abstract = {The Hindu Kush Himalaya region is experiencing rapid climate change with adverse impacts in multiple sectors. To put recent climatic changes into a long-term context, here we reconstructed the region’s climate history using tree-ring width chronologies of climate-sensitive Cedrus deodara and Pinus gerardiana. Growth-climate analysis reveals that the species tree-growth is primarily limited by moisture stress during or preceding the growing season, as indicated by a positive relationship between the chronology and precipitation and scPDSI, and a negative one with temperature. We have reconstructed 635 years (1384–2018 CE) of February–June precipitation using a robust climate reconstruction model that explains about 53% variance of the measured precipitation data. Our reconstruction shows several dry and wet episodes over the reconstruction period along with an increase in extreme precipitation events during recent centuries or years. Long, very wet periods were observed during the following years: 1392–1393, 1430–1433, 1456–1461, 1523–1526, 1685–1690, 1715–1719, 1744–1748, 1763–1767, 1803–1806, 1843–1846, 1850–1855, 1874–1876, 1885–1887, 1907–1909, 1921–1925, 1939–1944, and 1990–1992, while long dry periods were observed during the following years: 1398–1399, 1464–1472, 1480–1484, 1645–1649, 1724–1727, 1782–1786, 1810–1814, 1831–1835, 1879–1881, 1912–1918, 1981–1986, 1998–2003, and 2016–2018 CE. We found predominantly short-term periodicity cycles of 2.0, 2.2, 2.3, 2.4, 2.6–2.7, 2.9, 3.3, 4.8, 8.1–8.3, and 9.4–9.6 years in our reconstruction. Spatial correlation analyses reveal that our reconstruction is an effective representation of the precipitation variability in the westerly climate-dominated areas of Pakistan and adjacent regions. In addition to the influence of regional circulation systems like western disturbances, we found possible teleconnections between the precipitation variability in northern Pakistan and broader-scale climate modes or phases like AMO and ENSO. The study also highlights the prospects of tree-ring application to explore linkages between western disturbance, increasing intensity and frequency of extreme climate events, and analysis of long-term atmospheric circulation over the western Himalayan region. © 2024, The Author(s).},

abstract = {Progressive industrialisation and urbanisation in recent decades have dramatically affected the soil cover and led to significant changes in its properties, which inevitably affect the functioning of other components of the forest ecosystems. The total content of Pb, Cd, Zn, Fe, Cr, Cu, Ni, As, and Hg was studied in twenty-five plots at different heights in the topsoil (organic and humus horizons) formed from the Carpathian flysch in the area of the Silesian Beskids (Western Carpathians). The aim of this article is to analyse the spatial distribution of potentially toxic elements in the mountain forest topsoil in different types of plant communities and to determine the relationship between altitude and potentially toxic elements contamination. The soils studied are acidic or very acidic, with an average range of 3.8 (H2O) and 2.9 (KCl). Concentrations of the metals Cd, Zn, Fe, Cr, Cu, Ni, and Hg on the plots that were analysed are within the range of permissible standards for forest ecosystems in Poland, while Pb and As exceed the permissible standards for this type of ecosystem. Spearman’s rank correlation coefficient showed a high correlation between Fe–Cr (r(32) = 0.879; Pb-Hg r(32) = 0.772; Ni–Cr r(32) = 0.738; Zn-Cd r(32) = 0.734; and Cu-Hg r(32) = 0.743; and a moderate statistically significant positive correlation between Cu-Pb r(32) = 0.667 and As-Pb r(32) = 0.557. No correlation was found between altitude and the occurrence of potentially toxic elements. The geo-accumulation index (Igeo) index; on the other hand; indicates that Pb; As; and Cd have the highest impact on soil contamination in all study plots: it classifies soils from moderately to strongly polluted. The enrichment factor (EF) obtained for As and Hg indicates significant-to-very high enrichment in all areas studied. The potential ecological risk index (PLI) calculated for the sites indicates the existence of pollution in all areas examined. The highest risk categories (considerable to very high) are associated with cadmium and mercury. © 2024; The Author(s).},

abstract = {River channels are regulated in various ways and the fertile soils of valleys are occupied for agricultural purposes, accompanied by human settlements. In many places on the floodplains, gravel or sand is mined and former pits fill with water. The consequences are changes in water relations, changes in land use and land cover. Natural riparian ecosystems gradually disappear. In addition, river valleys are susceptible places for the spread of invasive plant species. In the section of the Upper Odra Valley discussed in this article, all of the aforementioned factors have played roles in shaping modern habitats. The present study shows the impact of human-induced changes on the transformation of the plant cover of the Upper Odra Floodplain. In designated transects, we studied land use changes from 1910 to the present day and examined plant species diversity. The results show that the more heavily transformed floodplain adjacent to the channelized channel has a higher level of species diversity than agricultural areas located along a section of the river with a natural channel course. Most of the river valleys are colonized by geographically invasive alien species, such as Reynoutria japonica, Reynoutria sachalenesis and Impatiens glandulifera, which have contributed to the fact that all of the species typical of the ash, poplar and willow riparian forests characteristic of this habitat type have retreated, which is the main reason for the very low biodiversity. © 2023 by the authors.},

abstract = {This paper reports on a detailed dendrochronological and dendroclimatological study of juniper trees (Juniperus seravschanica Kom. and J. semiglobosa Regel), sampled at seven sites having different elevations (2200 – 3100 m) and exposures (south-north) in the Pamir-Alay mountains, north-western Tajikistan. We developed seven new, well-replicated ring-width chronologies extending back over the last 219–1320 years. Our results confirm that the main climate factor influencing radial growth in this semi-arid region is variability in precipitation. However, they also indicate that there is a divergence in dendroclimatic responses between low- and high-elevation sites, where different limiting factors play a dominant role. The radial growth of J. semiglobosa at the uppermost treeline locations is the most sensitive to winter precipitation. Tree-ring formation in J. seravschanica at low-elevation sites is strongly limited by spring-summer drought conditions and by winter temperatures. The results of PCA analysis indicate that the relationships between growth and climate are linked more to elevation than to exposure. It was also found that negative growth extremes at low elevation sites may be triggered by strong dust storm events. Our findings clearly show that precisely planned selections of topographically differentiated sites, including elevation and exposure, are crucial for the possible reconstruction of different climatic elements in the high mountains of Central Asia for the last hundreds to thousands of years. © 2023 The Author(s)},

abstract = {The article presents the impact of Zn and Pb ore mining and land use on ecohydrological changes in the area of the Biała Przemsza valley in the historical aspect, with particular emphasis on the period 1941–2021. GIS was used to analyse the maps to identify spatial and temporal changes in land use. The following trends could be observed in the spatial development of the Biała Przemsza valley: rapid urbanisation and industrialisation in the 21st century, marked reduction in the surface area of arable land and sands, and dynamics of the increase in the surface area occupied by forests. Notable changes occurred in the plant ecosystems between 1941 and 2021 due to land management. Groundwater level lowering due to mining activity resulted in the change from wet meadows to fresh or dry xerothermic grasslands, while forest cover increased by 4% within the catchment area. The hydrographic network evolved. After the commissioning of the Zn-Pb ore mines Olkusz and Pomorzany in the 1960s and 1970s, a regional depression cone with an area of 400 km2 was formed, while the maximum groundwater inflows to the mines reached 360 m3/min. Changes in the hydrodynamic conditions have resulted in changes in the hydrogeochemical regime of the Triassic aquifer manifested by increased levels of, e.g., SO4 and Cl. Wastewater with lignosulphonate compounds from the paper factory caused periodic degradation of some of the water flowing into the Pomorzany mine. As a result of mining activity, the character of some sections of the Biała Przemsza river changed to an infiltrating one, the quantitative depletion of groundwater resources within the range of the mine drainage cone occurred, river springs disappeared, and the flow in the river decreased. At the same time, mine water was discharged to the tributaries of the Biała Przemsza. A radical reduction in the flow of the Biała Przemsza and its tributaries occurred after the decommissioning of the Zn-Pb ore mines at the turn of 2021 and 2022. © 2023 by the authors.},

abstract = {Abandoned anthropogenic sites are transformed when they come into use. In the present study, such objects were abandoned Evangelical cemeteries located in the Land of the Great Mazurian Lakes (northern Poland). This study aims to compare the concentrations of selected major (Ca; Na; Mg; Al; Fe) and potentially toxic elements (Zn; Cd; Pb) in the roots, leaves, and branches of Syringa vulgaris and buried necrosols and unburied soils in which this species grows. The soils analysed differ in their profile structure; in the case of burial necrosols, anthropogenic layers are present, while Brunic Arenosol has a natural horizon arrangement. Regarding pH, the soils analysed are characterised in the weakly acidic (6.6–6.8) to alkaline (7.2–8.6) range, both in KCl and H2O. Total phosphorus has high values in the humus and anthropogenic horizons, especially at coffin sites (Rudówka Mała: layer of Ccoffin—759 mg∙kg−1; Szymonka—844 mg∙kg−1). Necrosols are characterised by a slightly higher variation in major element content than soils outside the burial area. The highest elemental content in Syringa vulgaris is accumulated in leaves and roots. Potassium (K) has the highest content in the studied tissues, and cadmium (Cd) is the lowest. The study showed no significant differences in heavy metal accumulation for plants directly associated with necrosols and soils formed outside of burials, which is confirmed by analyses of environmental indicators. The study showed that plant chemistry is more influenced by the soil substrate and soil-forming process than the soil anthropogenisation associated with burials. There was no significant effect of burials on the chemical composition of individual parts of Syringa vulgaris. © 2023 by the authors.},

abstract = {Anthropogenic ecological ecosystems create favourable conditions for the growth of the nitrophilous medicinal species Chelidonium majus in six urban parks in Southern Poland. This study focuses on the concentrations of trace elements in the soils, leaves, stems, and rhizomes of greater celandine. The soil samples were taken only in the humus horizon (A), which averaged approximately 15 cm in thickness under the clumps of Ch. majus. Regarding the reaction, the soil samples tested can be described as slightly acidic (5.6–6.8 in KCl) to alkaline (7.1–7.4 in H2O). Organic carbon content at all sites is high, ranging from 3.2% to 13.6%, while the highest total nitrogen (Nt) content is 0.664%. The average total phosphorus (Pt) content in all samples is 548.8 mg/kg (and its range is 298–940 mg/kg), such values indicating its anthropogenic origin. In terms of heavy metals, Zn has the highest content in the analysed soil samples compared to the other elements, and its range is from 394.50 mg/kg to 1363.80 mg/kg in soil. In rhizomes, Zn also has the highest values (178.7–408.3 mg/kg), whereas, in stems and leaves, it varies (from 80.6 to 227.5 and from 57.8 to 297.4 mg/kg; respectively). Spearman’s rank correlation showed high correlations between the content of Pb, Zn, Cd, and As in the soil and rhizomes of Ch. majus. Despite soil contamination with Pb, Cd, and Zn, Ch. majus does not accumulate them in its tissues. However, the translocation of Hg and Cr from rhizomes to leaves was observed. The different concentrations of metals in each park result from the degree of diversity of the parent rocks on which the soil was formed. © 2023 by the authors.},

abstract = {The exploitation of mineral resources associated with human mining activities leads to the degradation of both terrestrial and aquatic biocenotic systems. The drastic disturbance of water relations as a result of the relocation of the riverbed of the Biala Przemsza River (southern Poland) for coal and filler sand mining will lead to changes in plant ecosystems. The purpose of this study was to determine and compare the diversity and distribution of vegetation in the Biała Przemsza valley in sections of channel straightening with the old riverbed and areas undisturbed by engineering works against the background of land use in temporal and spatial aspects. The results of the ecological and phytosociological studies showed that the composition of flora and vegetation types varied. Within the transformed riverbed, anthropogenic mixed forests with species characteristic of different ecological systems are developing, whereas the non-regulated section of the river is overgrown by an alder riparian forest with an almost complete species composition for this plant community. The highest Simpson’s biodiversity index was found in the anthropogenically disturbed section of the river (0.86), and in the undisturbed section, it was 0.83. Both sections of the river were dominated by species of the family Compositae, Poaceae, Caryophyllaceae, Rosaceae and Apiaceae. The diversity of the flora in the transformed sections of the valley is determined by the presence of mosaics and microhabitats, as well as the nature of the surrounding vegetation, which is reflected in the ecological requirements of the flora concerning light preference (moderate light [56.25%]), and almost 90% of the flora from the area of the regulated section of the valley develops on humus-poor and mineral-humus soils. Although this area has lost its original natural function, it is now valuable for selected economic and social functions, especially in highly urbanized regions. © 2023 by the authors.},

Due to its anticancer, antibacterial, hepatoprotective, and antioxidant properties, it has been used in medical treatments. In this work, the X-ray structure of methanol solvate of chelidonic acid was determined. Layers of chelidonic acid are held by hydrogen bonds via COOH and C = O fragments and additionally bridged by methanol. The formed H-bond network between two acid units is different from typical –COOH dimers observed, e.g., in crystals of isophtalic acid. The molecular structure of 2,6-dimethyl-γ-pyrone (2Me4PN) and chelidonic acid, a 2,6-dicarboxylic derivate of γ-pyrone (4PN), was verified in silico using density functional theory (DFT-B3LYP) combined with large correlation-consistent basis sets. The impact of –CH3 and –COOH substituents on 4PN ring structure, dipole moments, geometric/magnetic indexes of aromaticity, and NBO charges was assessed following unconstrained geometry optimization in the gas phase, chloroform, methanol, DMSO, and water with solvent effect introduced using the polarized continuous model (PCM). H-bond network formed in chelidonic acid–methanol complex was analyzed and their interaction energy estimated. Theoretical modeling enabled prediction of accurate structural parameters, dipole moments, and geometric/magnetic indexes of aromaticity of the studied 4PN, 2Me4PN, and chelidonic acid molecules. © 2022, The Author(s).},

abstract = {The local community of the Suleiman and Hindukush mountain systems in Pakistan has largely depended on the natural resources of the environment since ancient times. The ecosystem of these regions is under huge pressure due to a lack of awareness and the uncontrolled interference of communal, commercial, security, political, and ecological conditions. The present study was designed to illuminate the link between mountain society and the consumption of the benefits from Monotheca phytocoenoses using the ecosystem services concept from the sphere of the socio-ecological system to cultural relations. The use of this approach is very important due to the visible role and dominant status of Monotheca vegetation within the ecological system of the region. M. buxifolia is strongly connected with both local and cultural traditions and is counted as a key species, particularly for high-mountain inhabitants. We report that Monotheca phytocoenoses provide several services including shelter, food, fodder, medicines, and wood, etc., to the indigenous community and is highly valued in the local culture because of the poor economic condition of the society. The concept of this cultural keystone species is crucial for understanding ecosystem services and must be considered for the protection and conservation of these habitats. The results of field and social studies have shown that the stable maintenance of Monotheca phytocoenosis forests ensures the existence of key species as the most important providers of ecosystem services, e.g., provisioning, regulation, maintenance and cultural services, indicating the close relations between society and the protection of mountain areas. According to the results obtained, the mountains community of the studied area believes that tree species like M. buxifolia, F. palmata, O. ferruginea, P. granatum, A. modesta, J. regia, etc., are the key components contributing to the function of both the mountain ecosystem and communities’ well-being. This approach will be extremely useful for ensuring an inclusive management of the socio-ecological system of the Hindukush and Suleiman Mountain ranges of Pakistan. © 2022 by the authors.},

abstract = {As an anthropogenic element of urban landscapes, coal heaps undergo changes due to both natural and anthropogenic factors. The aim of this study was to determine the common development of soil under the influence of vegetation succession against a background of environmental conditions. Vegetation changes and soil properties were analysed along a transect passing through a heap representing a particular succession stage. It was found that changes in the development of vegetation were closely related to the stages of coal-waste disposal, where the initial, transitional, and terminal stages were distinguished. The mean range of pH (H2O) values in the profiles was 6.75 ± 0.21 (profile 1), 7.2 ± 0.31 (profile 2), 6.3 ± 1.22 (profile 3), and 5.38 ± 0.42 (profile 4). The organic carbon (OC) content in all samples was high, ranging from 9.6% to 41.6%. The highest content of total nitrogen (Nt) was found (1.132%) in the algal crust and sub-horizon of the organic horizon (Olfh-0.751%) and humus (A-0.884) horizon in profile 3 under the initial forest. Notable contents of available elements were found in the algal shell for P (1588 mg∙kg−1) and Mg (670 mg∙kg−1). Soil organic matter content was mainly dominated by n-alkanes (n-C11-n-C34) and alkanoic acids (C5–C20). Phytene and Phytadiene were typical for the algal crust on the initial pedigree. The initiation of succession was determined by the variation in grain size of the waste dumped on the heap and the variation in relief and associated habitat mosaic. Algal crusts forming on clay–dust mineral and organic material accumulating in the depressions of the site and at the foot of the heap can be regarded as the focus of pedogenesis. © 2022 by the authors.},

abstract = {Sustainable development policy emphasizes, among other things, the role of green areas in urban space. This remark applies in particular to post-industrial and post-mining cities. One of the elements of shaping the sustainable development of post-mining cities is that forests are often anthropogenic forest ecosystems growing in previously mining areas, one of the most characteristic elements of their spatial development. This article examines the role of urban forests in the post-mining area in Sosnowiec, located in the core of the Katowice conurbation in southern Poland. This article aimed to show the social perception of forests in post-mining areas among the local community and the features of urban forests. The social dimension of the interaction between humans and the environment is related to the issue of urban planning. Research was implemented based on quantitative, qualitative (CATI survey), and cartographic methods. The results indicate the significant role of forests in post-mining areas depending on their location in the settlement areas in a post-industrial city. The research emphasizes that residents perceive forests in post-mining areas of cities as an essential and expected recreational space. Notably, half of them do not see any threats therein. It is also expected that these areas will be better developed for recreational purposes in the future. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {The black locust Robinia pseudoacacia L. is a common species that originated from North America. In Europe, it is an invasive and introduced plant. Due to its low habitat requirements and ecological plasticity, this species colonizes new anthropogenically transformed areas quickly. This study investigated the chemical composition of selected tissues of Robinia pseudoacacia L. in five various habitats with different levels of anthropopression conditions in southern Poland. The presented research aimed to compare the chemical composition of black locust parts tissues (leaves; branches; and seeds) and the soil under its canopy. To determine the heavy metal contamination and enrichment in soil, the geoaccumulation index, enrichment factor, contamination factor, pollution load index, and potential ecological risk index were calculated. The results showed that all examined soils are considerably or very highly contaminated and the main heavy metals, which pollute the studied samples, are cadmium (1.3–3.91 ppm), lead (78.17–157.99 ppm), and zinc (129.77–543.97 ppm). Conducted research indicates that R. pseudoacacia leaves are the primary carrier of potentially toxic elements. Due to low bioaccumulation factor (BAF) values, it is clear that black locusts do not accumulate contaminants in such amounts that it would pose risk to its use in degraded area reclamation. The obtained results showed that R. pseudoacacia is able to grow in a wide range of habitats and could be applied for greening urban habitats and disturbed ecosystems caused by industry. © 2021 by the authors.

This represents a great opportunity for the implementation of the principles of sustainable tourism, which will avoid the mistakes associated with the uncontrolled tourism development currently observed in other mountain areas of the world. The aim of this article is to demonstrate, using the example of the Fann Mountains, how hydrogeosites in mountain areas can be valorised for the needs of cognitive tourism. The valorisation methods used in previous research to this point have focused on the evaluation of the objects themselves. This study additionally takes into account features of the surroundings of hydrogeostations, such as the visibility range, the vertical development of the view, and the diversity of the landscape. The conducted value assessments of the sites and their surroundings show that in both internal and external assessments the highest values were achieved by lakes and wetlands. This means that the evaluation of the surroundings has a strong influence on the results obtained and the choice of hydrogeotourism attractions. © 2021 by the authors.

abstract = {Post-mining waste from Zn-Pb ore exploitation undergoes processes of spontaneous succession and changes in soil chemical composition. The Zakawie area was industrially transformed by historical mining activity, ore enrichment, and the metallurgical processing of Zn-Pb ore. The subject of the study was to analyse the rate of vegetation succession (from 1999 to 2019), soil chemistry, and the relationships between them in an anthropogenic habitat with high concentrations of potentially toxic metals. Ecological and geochemical studies were carried out in an area contaminated with waste from a disused Zn-Pb ore-washing plant. Between 1999 and 2019, the transformation of grassland and meadow vegetation into scrub and forest–grassland communities was observed. This transformation led to a decrease in the area of Molinietum caeruleae meadow (from 25.8% in 1999 to 10.7% in 2019), whose place was taken by Prunus spinosa and Rhamnus cathartica. The community of xerothermic limestone grasslands completely disappeared, being replaced in favour of the Diantho-Armerietum and Prunus spinosa community. In this period, the share of lifeforms of plants and species composition (46 and 60; respectively) also changed. The Shannon and Simpson biodiversity index reached high values in the second investigation period, and it was 0.893 and 0.86, respectively. The anthrosols had a high content of Zn—85,360 mg kg−1, Pb—28,300 mg kg−1, Cd—340 mg kg−1, and As—1200 mg kg−1 . Carbonates, clay minerals, and fe-oxides are predominant in the mineral composition of the rhizosphere; the metal-bearing phases are stable; and hardly soluble minerals include smithsonite, cerussite, monheimite, hemimorphite, and oxides of Fe and Fe-Mn. Mineralisa-tion/crust processes formed on the epidermis, and their influences on root development were found. Scanning electron microscopy and energy-dispersive X-ray spectroscopy studies on rhizosphere soil components provide information on the type of minerals and their susceptibility to heavy metals release. The identification of some biotic and mineral structures in rhizospheres can be an interesting source of information on pedogenic processes identified in back-scattered electron images. © 2021 by the authors.

A fire zone in which the soil temperature exceeded 50°C was selected for our study. Soil analyses were carried out for three grain sizes – d > 1 mm, 0.063 mm < d ≤ 1 mm, and d ≤ 0.063 mm – enabling identification of the diversity of the chemical composition in soil fractions. The highest concentration of heavy metals is represented by Mn (212–6972 mg kg-1), Zn (127–3283 mg kg-1), Pb (33.6–1344.7 mg kg-1), Cu (38.9–101.4 mg kg-1), and major elements by Fe (14;300–117;400 mg kg-1) and Ca (900–63;600 mg kg-1). Soil chemistry showed variations within individual studied sites. The soil reaction ranges from acidic (4.3 in KCl and 5.26 in H2O) to moderate alkaline (7.96 in H2O and 7.31 in KCl), whereas TOC ranges from 1.21% to 14.60% and TN from 0.023% to 0.291%. The distribution of n-alkanes clearly showed a low degree of transformation of organic matter and characteristic high values of Pr/Ph ratio for humic coals and coal waste in the region. Grains with diameters greater than 1 mm exhibited completely different features than those of fractions smaller than or equal to 1 mm. High organic carbon content (14.60) was detected in the samples along with PAHs. The influence of fire on the chemical composition of all samples was identified using geochemical indicators. PCA analysis showed that the values of the variables were more closely correlated in finer grains than in the coarsest fraction. © 2021 John Wiley & Sons, Ltd.},

abstract = {Based on the analysis and interpretation of maps, remote sensing data published in the literature, and environmental reconnaissance, this article discusses environmental transformations in the Wojkowice area in southern Poland (up to the year 2020). A comprehensive analysis was carried out concerning spatial development, mining activity, hydrogeological conditions and the biotic environment. The current state of the hydrogeological conditions was also characterized. Mining activity in the vicinity of the studied town caused significant changes in its relief, which contributed to its area dropping by about 5 m. In fact, these terrain forms are overgrown by various forms of vegetation that colonized these areas both naturally and as a result of forest reclamation. The contemporary vegetation of Wojkowice differs from the potential natural vegetation, which is an indicator of the complete anthropogenization of the natural environment. Over 100 years of industrial activity in Wojkowice has also contributed to a strong transformation of the groundwater. There has been a quantitative depletion of usable groundwater in the Triassic and Carboniferous formations. With inflows to the ore mines of up to 17 m3/min, the groundwater table has dropped by more than 60 m. The aquifer of Muschelkalk has been practically drained. At present, wells extract the waters from the Röth aquifer. There has been a major transformation of groundwater chemistry. The waters of the Triassic carbonate complex are anthropogenically transformated and are characterized by increased mineralization, multi-ionic types and usually with a quality class III and IV, and, therefore, they require some treatment. © 2021 by the authors.

Vegetation analysis involved the determination of species composition, life forms, and synecological affiliation. The mosaic diversity of the granulometric composition of the stored material and dynamically changing soil temperature had an impact on the character of vegetation. A specific type of flora, with various ecological requirements, was formed. Hemicryptophytes and apophytes predominated, especially in thermally active zones. The distribution of the range of vegetation due to changes in soil thermics was examined during three periods within a selected transect, in which three types of surfaces with varying soil thermics and smoldering fire directions were distinguished. Temperatures ranged from 9.9 to 139 °C at a depth of 20 cm and, simultaneously, from 3.1 to 69.0 °C on the surface. Total organic carbon content in all samples ranged from 1.7 to 7.6 and, simultaneously, from 3.1 to 4.5% in the active fire spots. The concentration of total nitrogen ranged from 0.023 to 0.29%. Soil reaction (pH) fluctuated between 5.8 and 8.0 (in H2O). The variability of the range of vegetation in time and space indicated the directions of movement of fire spots. The analysis showed that underground temperature has a significant impact on the distribution and species composition of plants growing on coal-waste dumps. © 2021 Elsevier Ltd},

abstract = {The indigenous societies of the Fann Mountains were and remain dependent on the resources of the natural environment. The present study aimed at investigating the relationship between mountain communities and the use of ecosystem services that are subject to change due to the influence of social, economic, and political conditions. The study made use of the concept of ecosystem services, which extends the scope of analyses of the socio-ecological system to the sphere of cultural relations. The application of this approach was crucial due to the dominance of juniper forests within the ecological system, given that the juniper, as a result of its connection with religion and local traditions, considered a key species for the mountain societies. The identified structure of the ecosystem services indicates the significance of the juniper in providing the indigenous community with services which, due to the economic situation of the society are characterised by greater value (wood; food; medicine) than cultural ecosystem services. Identification of ecosystem services taking into account the concept of cultural keystone species should be a starting point for the protection and restoration of juniper forest. The results of field and social studies have shown that the stable maintenance of juniper forests ensures the existence of key species as the most important ecosystem services, e.g. provisioning, regulation and maintenance and cultural, indicating the correct relations between the society and the protection of mountain areas. The obtained results showed that the inhabitants claim that juniper forests with the participation of Juniperus semiglobosa and Juniperus seravschanica are the main elements determining not only the functioning of mountain ecosystems, but also the communities living there.

abstract = {This research was conducted on an area of inland sands characterised by various degrees of overgrowth by vegetation and soil stabilisation. This landscape’s origin is not natural but is connected to human industrial activities dating from early medieval times, which created a powerful centre for mining and metallurgy. This study aims to identify the changes in the above-and belowground phytomass in the initial stages of succession and their influence on the chemical properties and morphology of the soil. It was found that Salix arenaria dominated in primary phytomass production in all plots tested. The amounts of this species found in each community were as follows: 8.55 kg/400 m2 (algae–mosses), 188.97 kg/400 m2 (sand grassland–willow), 123.44 kg/400 m2 (pine–willow–mosses), 14.63 kg/400 m2 (sand grassland–mosses–willow), and 196.55 kg/400 m2 (willow–pine–sand grassland). A notable share of Koeleria glauca was found in the phytomass production of Plots IV (45.73 kg) and V (86.16 kg). Basic soil properties (pH; Corg; Nt), available plant elements (P), and plant nutrients (Ca; Mg; K; P; Fe) beneath the dominant plant species were examined. Soil acidity (pH) varied greatly, ranging from acidic (pH = 3.2) to weakly acidic (pH = 6.3). The content of organic carbon (Corg) in individual plots beneath the dominant species in the humus horizon ranged from 0.28% to 1.42%. The maximum contents of organic carbon and total nitrogen were found in organic (O) and organic‐humus (OA) horizons. The highest Pavail content was found in organic and organic‐humus horizons, ranging from 10.41 to 65.23 mg/kg, and in mineral horizons under K. glauca (24.10 mg/kg) and Salix acutifola (25.11 mg/kg). The soil features and phytomass were varied differently across individual sites, representing different stages of succession. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {Coal-waste dumps are an integral part of the environment and shape the landscape of coal basins. This study aimed to present an analysis of environmental changes in terms of land use and changes in vegetation on self-heating coal-waste dumps of different ages. Spatial and temporal analyses of land relief and land cover in the area of the investigated coal-waste dumps were performed. The investigated areas differed in size, shape, management, and land cover. Thermally active zones were identified. The results showed that the species composition of the flora is diverse, but representatives of the Asteraceae family dominate on both dumps. The diversity of flora in the investigated dumps depends on the presence of mosaic-and microhabitats (often of an extreme nature) and the nature of the vegetation in the surroundings, which is manifested by the participation of socioecological groups of flora. The pace and dynamics of succession on burning coal-waste dumps depends on the stage of the fire, the topography, and the nature of the substrate. The investigated changes in the elements of the environment are important from the point of view of application research and monitoring of postindustrial areas, which may allow for the optimal management of postmining dumps. © 2020 by the authors.

abstract = {Ecosystems of city parks are one of the most important refuges of biodiversity in urbanized areas. Recently, naturalists have had an increased interest in floristic diversity in regions that have been drastically modified by human activity, particularly in urban spaces. Investigations were conducted at various levels of the biological organization, to protect the environment and to promote floristic diversity. The aim of this study is to present floristic diversity in urban parks in southern Poland. The research was conducted in 10 parks located in 3 cities (Dabrowa Górnicza; Sosnowiec and Bȩdzin). These parks have been formed at different times, on various parent rocks. They are both natural and anthropogenic in origin and have different sizes (the smallest being 6 ha and the largest 67 ha). Their common features are way of use and management. The results of this investigation have confirmed 426 vascular plants belonging to 83 families and 247 genera. The highest number of species belongs to Asteraceae and Poaceae. Grabek Park is the most species rich (288) in comparison to the other parks investigated. Research on urban parks shows important links between floral diversity and biodiversity within highly urbanized areas in city centres and in urban spaces in general. This variety includes both native species and alien species, which are often called 'park species' with a decorative origin. © 2019 Oimahmad Rahmonov et al, published by Sciendo 2019.},

abstract = {The article presents an analysis of directions of internal and international migrations undertaken by Polish pensioners. A typology of migration directions is proposed. We use the method of a table of signs to define five major types of pensioner migrations. We show the variability of these types over time, from the Type J (moderately mobile; consistent) in the 1990s to the Type H (moderately mobile; mixed) at present. A detailed analysis reveals a major difference between international and internal migrations: The former are mainly due to economic reasons and the latter to reasons related to housing. The obtained results allow us to conclude that pensioner migrations constitute an important factor in the social and economic development of local communities, especially in the day and age of society ageing and lengthening life expectancy. © 2020 John Wiley & Sons, Ltd.},

abstract = {The study focused on the changes in vegetation and soils on an undeveloped area of coal mine spoil heaps. The process of vegetation changes was evaluated on the basis of historical cartographic materials and fieldwork. Changes of vegetation in nearly 200 years are presented herein. The main purpose of this study is to present an analysis of spatio-temporal changes in vegetation and their influence on soil features. The diversity of ecological species in terms of habitat requirements, tendency of hornbeam communities formation, and the relationship between forest communities and soil features was found. The basic soil properties were examined under selected plant communities (pH; Corg; Nt), available forms of elements (P; K; Mg), and as plant nutrients and heavy metal occurrence (Fe; Zn; Mn; Co; Cd; Pb; Sr; Cr; Cu). The soil organic carbon (Corg) content varied from 3.17 ± 0.007% to 17.7 ± 0.21% and significant differences were observed between sites. The highest total nitrogen (Nt) content was recorded in the soils of the sites that were represented by Populus-Betula stands (0.60 ± 0.01%). Soil acidity (pH) varied greatly, ranging from acidic (pH = 4.1) to weakly acidic (pH = 5.9). The highest value for Mgavail (205.43 ± 0.5 mg·kg−1) was noted in the soils under Calamagrostis epegijos (L.) Roth community and for Pavail (184.07 ± 3.77) and Kavail (346.19 ± 2.92 mg·kg−1) under the Quercus-Pinus stand. On all sites, Zn was a dominant element and its concentration ranged from 526.1 to 1060.4 mg·kg−1. Obtained results show how important it is to study the issue of vegetation changes and the formation of the landscape within an industrial city. The described results are important for the management of urban greening issues. Human influence on the disintegration and development of the natural environment is clearly visible. Due to the diversity of former mining areas and their time of creation, the studied area is one of the most important experimental areas for the determination link between vegetation and soil. © 2020 by the authors.

abstract = {On the basis of the analysis and interpretation of maps, published literature, and environmental reconnaissance, this article discusses environmental transformations in the area of the KuznicaWarezynska sand mine in southern Poland over the years 1944-2015. A comprehensive ecological analysis was carried out concerning spatial development, mining activity, hydrogeological and hydrological conditions as well as the biotic environment. Among the unfavourable changes found were a drastic reduction in the agricultural function of the area (from 7.03 to 0.47 km2), mainly due to periodic activity of sand mine in 1967-2002, covering an area of about 5.80 km2, the destruction of the original biocenoses, the depletion and deterioration in quality of the groundwater resources, and man-made transformations of the hydrographic network (during the mine's activity its length reached over 103 km). Vegetation changes during the 70-year period examined were closely related to human mining activity. The greatest changes occurred at the end of the 1960s when large areas of pine forest were cut down. The analysis of vegetation in the former workings demonstrated that the diversity of habitats within the workings results in a significant increase in species (367 plant species; 2002 birds) and community diversity (Molinion caeruleae; Molinion caeruleae; three Natura habitats) there compared to the adjacent areas. On the other hand, favourable changes included the construction of a flood control reservoir, with an area of 560 ha and a volume of 51 million m3, created in 2003-2005, making the area more attractive for tourism and recreation, and an increase in biodiversity, including the establishment of a Natura 2000 site. © 2020 by the authors.},

abstract = {Saccharides are common constituents of soils, but their role and origin in the initial phases of pedogenesis remain unclear. Here we show the detailed composition of neutral sugars extracted from arenosols at different development stages, combined with additional lipids of diverse origins using gas chromatography-mass spectrometry (GC–MS). During the first stage (I) of development sucrose is the most abundant saccharide in the soil crust at up to 45,000 µg/g TOC. Sucrose is also the predominant compound in the second and third development stages, but its concentration decreased to the range of 1600 to 16,000 µg/g TOC. Stages II and III of soil development were characterized by a gradual increase in arabitol, mannitol and trehalose, compounds typical for fungi and lichen. Their abundances increased from several percent (compared to the major sucrose) to 10–32% for mannitol and 34–54% for trehalose. Moreover, in stage III there was a considerable increase in the contents of the saccharides: pinitol, myo-inositol, scyllo-inositol, arabinose, together with non-sugar compounds: dehydroabietic acid, p-hydroxybenzoic acid, gallic acid and sitosterol. All these latter compounds are higher plant markers, mainly derived from conifer detritus. The relationships between the ratios of trehalose/sucrose vs. (mannitol + arabitol)/sucrose and TOC vs. (mannitol + arabitol)/sucrose differentiated precisely the top soil layer of arenosols which are covered by different stages of biological soil crust. Our study shows that free sugars, supplemented by lipid biomarkers and total organic carbon contents, are good indicators of soil in the initial phase of pedogenesis. © 2019 The Authors},

abstract = {Changes in forest range are caused by human activity in many regions of the world. The aim of this paper is an attempt to determine the impact of pastoral and forest management on changes in forest cover and their fragmentation in the Silesian Beskids (southern Poland) in 1848–2015. Historical maps and landscape metrics were used to study changes in forest cover. Using a digital map of forests, analyses of the distribution of forest communities, site types and their condition were conducted. Since 1848 the forest area has increased by 11.8%, while the area of forest core zones has increased by 16.2%, accompanied by a 4.5% reduction in the forest’s internal buffer zone. From the mid-nineteenth century, the forest range has been systematically growing from 82.1 to 93.9% because of the pastureland abandonment and forest regeneration, despite temporary logging resulting in forest fragmentation. Minor changes in core area index (CAI) from 80.41 to 87.55 indicate that pastoral economy did not result in considerable fragmentation of forests. The impact of forest management was greater as the sites characterised by natural condition occupy only 28% of the forest land and anthropogenically transformed ones dominate occupying over 50%. An artificial spruce monoculture was died-off and large felling areas were created at the beginning of the twenty-first century covering almost 40% of the study area. © 2020 by the authors.

The aim of this article is to test a new method of landscape profiling, enabling measurement of the extent of anthropogenic transformation of a landscape and indication of zones of landscape disturbance. The method is based on an interdisciplinary analysis of various aspects of the landscape, consisting of an assessment of the degree of overlap between natural and non-natural boundaries. Three types of relationships were identified: landscape convergence (LC), landscape divergence (LD), and zone of landscape disturbance (ZLD). This analysis makes it easier for urban planners to change their existing land development plans. The method can be used universally to detect inappropriate land development, which is important in diagnosing the condition of landscapes and can be used in the spatial planning of cities and suburban zones. © 2019, © 2019 Newcastle University.},

abstract = {Although population ageing is progressing, seniors migrate with increasing frequency. This paper explores the question why Polish pensioners decide to migrate, as existing research has not provided satisfactory explanations. Reasons for migrations were determined on the basis of pensioners' answers to a questionnaire survey. The results show that migration decisions are taken for a number of reasons, which depend, inter alia, on the respondents' education level, age, and sex. For women as well as for men, the economic aspect plays a crucial role (e.g.; building or buying a new house). Ward's method was employed to distinguish five main migration types according to the main motivating factor; that is, family and finance, family, environmental, economic, and health. An analysis of internal as well as external migrations of Polish seniors shows that they differ considerably from migrations of seniors in other countries. Due to their unsatisfactory finances as well as deficits in knowledge of foreign languages, Polish pensioners, unlike their peers in other countries, rarely decide to settle down abroad. The Polish model of multigenerational family in which seniors assist their children in raising their grandchildren also contributes to lower emigration. © 2018 John Wiley & Sons, Ltd.},

The results of the palynological analysis indicate: (1) the dominant role of pollen from lime (Tilia) among the tree species; (2) substantial amounts of pollen from maple (Acer); (3) a significant presence of pollen from heather (Ericaceae), and 4) an increase in the contribution of pollen from plants (including grains) associated with human activity. A comparison of data obtained with results from analyzing the contemporary pollen rain in different plant communities of the other parts of Poland indicates that during the formation stage of the Holocene soils in the Bledow Desert, the aforementioned tree species were dominant in the composition of forests and that the presence of a large contribution of pollen from lime and pollen in the soil was determined by their properties and ability to persist in the paleosol. © 2018, Pleiades Publishing, Ltd.},

The branches of the Silk Road in central Asia clearly coincide with loess areas, where many settlements were erected based on the presence of fertile loess soil and water. The aim of the study was to analyse the environmental factors that led to the growth and decline of one of the most important Silk Road loess towns, ancient Panjikent, as an example of human and climatic impacts on landscape changes. The town, established in the fifth century, quickly became one of the most important cities of Sogdiana. Local loess material was used for the production of the sun-dried bricks. Rapid population growth led to deforestation and consequently increased the intensity of erosion rates and reductions in cultivation area. A period of drought near the end of the first millennium AD influenced the final abandonment of the ancient town and its relocation to the lower terrace of the Zarafshan River. A decline in natural and agricultural resources and subsequently climatic forces caused a decline in the number of cities in semiarid regions of central Asia. Copyright © University of Washington.

In this paper, winery landscapes are studied at two levels: typological (as a repeatable; specific type of area with precisely defined characteristic features), and regional (regional areas that are unique and individual). The authors analyze the evolution of winery landscapes over time and describe their natural and historical aspects. A wide range of factors were taken into consideration: historical and political, socio-economic, cultural and religious influences, as well as the natural environmental background.

Thirty samples were collected from two old buildings from a village located in the western Pamir-Alay; eight cores were taken from temple. Most of the construction wood was juniper species. The object chronologies crossdated well with the previously published chronology based on living juniper trees from western Pamir-Alay. The results of dating revealed that investigated structures are composed of wood coming from several periods. The oldest pieces of wood dated back to the 11th and 12th Centuries. Most timber samples come from the turn of the 17th and 18th Centuries, which were probably the period of intense development of the Artuch village. Besides dating of the wood samples from these historic structures, our investigation provides the opportunity to extend the currently existing regional tree-ring chronology for future climate reconstruction of the Pamir-Alay and High Asia. Dated sequences were assembled into a 1012-year chronology spanning the period 945-2014 C.E. and strengthened the replication of its earliest part (with critical 0.85 EPS value since the beginning of the 13th Century). © Copyright 2018 by The Tree-Ring Society.},

abstract = {Landscape changes in the Carpathians are related to centuries of human activity, which can be regarded as the key component of global change. Changes in mountainous regions are mainly caused by agriculture, urbanization, forest cutting for production and land abandonment. This paper aimed to assess the impact of natural and historical-cultural factors on forest ecosystem transformations occurred in the period 1848-2014 in two small areas (about 45 km2) on the Beskid Mountains (southern Poland). The comparison of historical and current maps, along with the application of GIS and field verification, allowed a full interpretation of changes in land use in the studied areas. A decrease of 58.0% in non-forest areas was observed in the considered period, while the forested area grew systematically by 28.3% and the forest-field boundary lowered in altitude. Current forest ecosystems are distributed as a mosaic and mainly consist of Dentario glandulosae-Fagetum, Luzulo nemorosae-Fagetum, Abieti-Piceetum montanum, with logged sites taking up large areas. Forest ecosystems include valuable semi-natural meadows such as Gladiolo-Agrostietum, Hieracio-Nardetum, Arrhenatheretum medioeuropaeum, Cirsietum rivularis or Juncetum effusi, whose extension is reducing and fragmentation increasing due to the recolonization of forest tree species after abandonment. We concluded that trends in land use in the Carpathians were mainly determined by non-environmental factors related to the development of farming-pasturing and forest management. The applied approach could be extended to other regions in the Carpathians which were subject to analogous historical cultural influences. Moreover, our results allow for a comparison with other regions which are subject to similar impacts of natural processes, but to different impact of historical and cultural processes. © SISEF.},

abstract = {The paper presents the varied presence of nitrates and phosphates in water from caves located in Częstochowa and Kraków, in urban, strongly anthropogenic conditions, representing the vadose zone of the fissure-karstic-porous massif of Upper Jurassic limestones. Hydrochemical research was carried out by the authors in the Cave on the Stone in Częstochowa in 2012–2015, in caves of the Zakrzówek horst from 1996 to 2002, and in the Dragon’s Cave by the research team of J. Motyka in 1995–1998. A number of NO3 and PO4 measurements were performed in waters sampled at these research sites: 20 measurements each of NO3 and PO4 at the Cave on the Stone, 228 of NO3 and 422 of PO4 at Zakrzówek, and 19 each of NO3 and PO4 at the Dragon’s Cave. To assess the quality aspect of N and P compounds in waters from the Cave on the Stone, the results of geochemical modelling were processed using PHREEQC software. In cave waters, the oxidised form of nitrogen NO3 − predominates; in surface waters in the vicinity, unoxidised forms prevail: NH4+, NH3, and NH4SO4 −. Among phosphorus speciations, dissolved forms are dominant: HPO4 2−, H2PO4 −, and the insoluble form CaHPO4; in surface waters, these forms are practically absent. Transformations of water chemistry in ‘urban’ caves, often centuries old, manifest themselves in, inter alia, the occurrence of multi-ionic waters, including seasonal variations and extremely diversified concentrations, with very high concentrations in subpopulations of NO3 (0.2–485 mg dm−3) and P (0.02–6.87 mg dm−3). The common presence of NO3 in waters of the phreatic zone of the Częstochowa Upland, an area developed in an agricultural direction, is documented by, inter alia, the exploitation of intakes supplying the city of Częstochowa (10–57 mg dm−3, 2011) and crenological studies from 2008 to 2015 (NO3, 2–58 mg dm−3), at simultaneously low phosphate concentrations (PO4, 0.02–0.24 mg dm−3). © 2017, The Author(s).},

abstract = {Active tectonics reflect high seismicity rates in the Pamir and surrounding areas. Long-lived trees growing in the western Pamir-Alay mountains are affected by ground accelerations and seismic-induced geomorphic processes. At a high-mountain site in the Pamir-Alay, 45 juniper trees were sampled in order to analyze the potential role of these trees in the reconstruction of disturbance events. Although the trees have a maximum age c. 500 years, only the period of the last 100 years was analyzed, aiming for the dendrochronological identification of earthquake events known by historic documents and measurements. Analysis mainly showed non-climatic growth suppression and releases. These signals were identified as the results of tectonic disturbances. Tree-ring data recorded many earthquakes from which the most distinct were: 1907, 1923, 1943, 1955, 1982, and 1998. The 1907 and 1923 large earthquakes took place after the vegetation period; therefore, growth reduction appeared in the following year. The 1943, 1955, 1982, and 1998 events occurred just before or during the vegetation period and therefore induced the immediate reduction of tree rings in the earthquake year. The identification of the characteristic growth ring patterns, which are a response to large earthquakes, will enable the reconstruction of these events in the past on the basis of centuries-long dendrochronological records. © 2017 Elsevier Ltd},

abstract = {Detailed analyses were conducted of human impact on juniper forest landscapes occurring within the Zarafshan Range (Pamir-Alay). Juniperus seravschanica and J. semiglobosa belong to forest-forming species in Central Asia. At present, juniper forests all over Tajikistan are seriously threatened as a result of excessive logging and cattle grazing. The aim of this paper is to present juniper forest transformation as a result of human activities as well as the diversity of soil properties in the organic and humus horizons in the altitudinal system of soil zonation. Three groups of phytocoenoses were distinguished: those with a dominant share of Juniperus seravschanica; those with a dominant share of J. semiglobosa; and mixed. Associations with Juniperus seravschanica and J. semiglobosa feature several variants of phytocoenoses with dominant species: Artemisia lehmanniana, A. dracunculus, Eremurus olgae, Festuca sulcata, Ligularia thomsonii, Stipa turkestanica, Thymus seravschanicus, and Ziziphora pamiroalaica. The collected soil samples differ in their granulometric composition. Gravelly cobble fractions >2 mm are dominant; the share of sandy particles <2 mm is much lower (about 10–20%). Fraction 0.5–0.05 attains 35% on average. The Corg content of the soil varied from 0.26 to 11.40% in the humus horizon (A) and from 4.3 to 25% in the organic (O). Similar relationships were reported in the case of Ntot concentration. A clear relationship can be observed between concentrations of Corg and Ntot. Soil pH varied, ranging from very low acidic (pH 5.5) to neutral (pH 8.5). The content of available P varied; high concentrations were noted in organic (O) (40.46–211 mg kg−1) and mixed horizons (OA) (2.61–119 mg kg−1). Maximum accumulations of Pavail (1739.6 mg kg−1) and Ptot (9696 mg kg−1) were observed at a site heavily affected by intense grazing. Concentrations of Mgavail varied from 116 to 964 mg kg−1. Most of the analysed soil profiles lacked an organic horizon; only thin humus occurred. © 2017, The Author(s).},

They provided the background for considering conditions for the functioning of juniper forest ecosystems. The uniqueness of these ecosystems also relies on the longevity of Juniperus seravschanica Kom., J. semiglobosa Regel and J. turkestanica Kom. Physiognomic features of the landscape are conditioned by the habitat, climate, landforms, and recently also by anthropopressure. The ecological, environmental and the cultural importance of juniper trees makes them a distinctive and determinant feature of the landscape. Currently juniper forests across Tajikistan, including those in the Zeravshan Mts., have been significantly disrupted as a result of chaotic, uncontrolled and excessive felling. The purpose of this article is to present natural conditions of juniper forest ecosystems, the impact of anthropogenic changes on their functioning as well as the occurrence of endemic species within them.

abstract = {Millennial long tree-ring records are crucial for better understanding temperature and hydroclimatic variability over the globe. Juniper is one of particularly long-lived species, which can provide more than a thousand-year record, especially in Central Asia. However, there is a lack of dendrochronological series from the Pamir Mountains. Here we report the first 1010-year (AD 1005–2014) juniper tree-ring chronology from the mountain ranges of north-western Tajikistan, the western Pamir-Alay. We present the potential of Juniperus semiglobosa and Juniperus seravshanica in developing millennia-long records. We sampled three study sites at the elevations from 2200 to 3500 m. In general, the climate-growth analyses show that radial growth of the Himalayan pencil juniper is positively correlated with the winter precipitation and spring temperature. At some sites tree rings were also positively correlated with summer temperature. Our findings demonstrate the importance of developing the tree-ring data network for the Pamir-Alay and its potential for reconstruction of hydroclimatic variability over the last thousand years in this region. © 2016 Elsevier GmbH},

Terrain regulation and drainage brought about an intensification of the overland runoff, and a decrease in irrigation of the territory. Due to soil overdrying, some tracts of the valley are experiencing a moisture deficiency. Peat drying can lead to negative consequences, because shallow peats mostly occur on the study territory. Disappearance of peaty soils acts to decrease the degree of suitability of the riverside territories for economic purposes as well as their capacity for recovery. The schematic map of vegetation distribution along the river valley prior to and after melioration as compiled from results of field observations displays differences between mosaic quasi-natural vegetation and areas of typical agrocenoses. The preservation of the natural values along the Brynica valley is possible through balanced economic management, while the differentiation of topography contributes to creating favorable conditions for the formation of biodiversity. © 2016, Pleiades Publishing, Ltd.},

The purpose of this project, carried out in 1995-2005, was to observe changes in the chemical composition of infiltration waters, especially Sr, Ba, Fe, Mn, and Zn concentration in precipitations, in soils and in caves within an unsaturated zone and a saturated zone situated in a carbonate massif. Field research was conducted in the Prądnik River’s drainage basin and at the Zakrzówek horst in Kraków. The chemical and mineralogical composition of limestone samples from 11 different quarries and natural exposures in the Kraków Upland were studied. The mineralogical research was conducted using the Roentgen diffraction method. The concentration of Sr, Ba, Fe, Mn and Zn in 700 samples from precipitation, caves and saturated zone waters was analysed. The determinations were made using mainly the ICP-AES Plasma 40 and ICP-MS Elan method. To assess the quality aspects of the migration of heavy metals, the results of the geochemical modelling were accounted for using the PHREEQC software. The hydrochemical research has shown distinct variability of concentrations of the analysed minor elements in different forms of precipitation (the highest concentrations being observed in sleet and the lowest in pure snowfall). In rainwater as well as in waters of the unsaturated and saturated zones, quantities of the five chemical elements appeared in the following decreasing order: Fe>Zn>Mn>Sr>Ba and Sr>Ba>Fe>Zn>Mn. The chemical composition of infiltration waters in the carbonate massif changes vertically. The fundamental trends in the waters of this area include an increase of Sr and Ba concentrations, a decrease of the concentration of Zn, and static concentrations of Fe and Mn. © 2015, Polish Society Magnesium Research.

The soil profiles have been compared to the control soil (a Brunic Arenosol according to the WRB classification) occurring beyond the cemetery area. The changes in the studied burial soils are mainly manifested in their morphology: the disturbance of the primary genetic horizons and the presence of mixed soil horizons and artifacts (bones; coffin remains; limestone-concrete debris of the cemetery infrastructure). Such changes in the chemical properties as an increase in the contents of the organic carbon and total nitrogen and the soil reaction were observed. Our studies have shown that the highest Ptotal concentration is observed in the A horizons of the anthropogenic burial horizons and undisturbed cemetery soils. The content of phosphorus in the Necrosols is significantly higher than that in the control soil profile, as is observed for the Cgrb layers of burial Necrosols. The morphology and chemistry of the undisturbed cemetery soils are very similar to those of the control profile. © 2014 Pleiades Publishing, Ltd.},

abstract = {The complete destruction of primary vegetation and soil cover as a result of human activity is the most drastic example of disturbances in ecosystem functioning. Despite the fact that inactive limestone and dolomite quarries are relatively common in the southern part of the Silesian Upland (the Jaworzno Hills mesoregion), there are not many studies on the processes of transformation of landscape within them. The aim of our paper is to present preliminary results of research on overgrowing processes in the select objects using applied GIS methods. The studies show that differentiation of overgrowing processes in investigated quarries depend on the time that passed from the end of exploitation and of the type of surrounding landscapes. The major fragments of quarries were overgrown by species with a wide ecological spectrum, both herbaceous species (e.g. Calamagrostis epigejos) and pioneering trees (e.g. Betula pendula; Salix caprea). Additionally, especially on the edge of investigated quarries, plant communities form class Rhamno-Prunetea and grasses from Cirsio-Brachypodion pinnati union formed. In total, 145 species of vascular plants were identified, including 2 strictly protected and 7 partially protected taxons. Research is based on archival aerial photographs and the latest orthophotomaps from the 1950s to 2009. All cartographic materials were calibrated and registered in Poland CS92 coordinate system (EPSG: 2180). Registration and digitalization of vegetation patch ranges were conducted with applied MapInfo Professional software.},

abstract = {Ecohydrological monitoring was conducted in the period of 1999-2013 (and beyond) in the riverhead section of the Kłodnica Valley, in the riverside ecosystems in the southern part of the Silesian Upland. The aim of this study was to analyze and evaluate the impact of mining on the changes in water conditions and their impact on plant ecosystems connected with waterlogged habitats in the valley. The monitoring included observations on the variability of the water table, the size of mining subsidence and the scale of ground deformation. In order to monitor the range of Allium ursinum and Veratrum lobelianum, five permanent plots of 100 m2 each were established. During coal extraction (2000-06) the water table depths ranged from 0 to 2.4 m in the uplands, and from 0 to about 1 m in the valley, and the waterlogging of the substrate was dependent on precipitation conditions (amount and distribution of rainfall throughout a year). At that time, the surface of the area lowered by a maximum of 1.78 m. After the coalmine operation ceased, i.e. in the period of 2007-13, the subsidence significantly declined and did not exceed 15 cm. The monitored populations of Allium ursinum L. and Veratrum lobelianum Bernh. did not show considerable changes in terms of the area they occupied. However, a trend was observed to increase their ranges not only in the plots but also in the whole area. Local decrease in the ranges of the tested species was caused by forest management carried out at the same time. According to the results of the monitoring, the changes evoked by the mining activities are dependent on geological and lithological conditions, the position of the water table, the size of the mining operation, and ground subsidence, as well as the technology of extraction. It was found that the impact of mining on riparian ecosystems in the study area has not caused negative changes in their functioning.},

abstract = {The aim of our paper is to identify the main trends in changes in land use of select urban parks in Sosnowiec and Będzin towns during 1927-2009 in light of changes to the urban areas. Research included two urban parks: Sielecki in Sosnowiec and Góra Zamkowa in Będzin. The analysis was based on old maps (from 1927; 1960s/70s; and 1990s) and the latest available orthophotomaps of the study area (2009). The results obtained on the basis of geographical information systems (GIS) shows significant differences, both in terms of spatial and quality changes in the land use in all urban parks, conditioned by their location in the different types of landscapes. The identified changes are linked to the wider range of functions taken over by parks, and also of changes in urban planning strategies. The GIS methods were helpful in interpretation of identified changes. Increasing forest areas is observed in the last research period and has a connection with the flora of both parks. The role of urban parks is particularly noticeable in strongly urbanized and industrialized areas - in the urban-industrial agglomeration and conurbation. The urban parks in these areas are an interesting problem in terms of geographical, botanical, and landscape ecology research. The documentation, monitoring, and protection of the oldest and the most valuable parts of the urban parks (urban forests) are important in light of the fact that urban parks are linked with local history.},

The aim of the research was to investigate the chemical-physical features of soil under a closed and dense canopy of R. japonica, the chemical composition of the R. japonica leaves, and to compare the content of certain elements in the soil-plant-soil system. The soil organic carbon (Corg) content varied from 1.38±0.004% to 8.2±0.047% and the maximum in leaves was 49.11±0.090%. The lowest levels of total nitrogen (Ntot) in soil were recorded on the heavily disturbed sites (till 0.227±0.021%). Soil pH varied greatly, ranging from acidic (pH=4.0) to neutral (pH=7.7). Heavy metal content differed significantly among the study sites. At all of the sites, both in the case of soil and plant leaves, Zn was a dominant element and its concentration ranged from 41.5 to 501.2 mg·kg-1 in soils and from 38.6 to 541.7 mg·kg-1 in leaves. Maximum accumulations of P (2103.3±15.3 mg·kg-1) and S (2571.7±17.6 mg·kg-1) were observed on the site that had been influenced by agricultural practices. The results obtained showed that R. japonica is able to accumulate high levels of heavy metals. © 2013 Versita Warsaw and Springer-Verlag Wien.},

abstract = {South-central Poland has thousands of anthropogenic lakes. Our study investigated the diversity of the chemical composition and concentration of trace elements in the lake bottom deposits. Particle size distribution was determined using sieve analysis and the combined areometric-sieve method. Concentrations of oxides (SiO2; TiO2; Al2O3; Fe2O3; MnO; MgO; CaO; Na2O; K2O; P2O5) were determined in sediments using the ICP method. Moreover, loss on ignition was measured and concentrations of Zn, Pb, Cu, Cd, and Ni were determined. Concentrations of As, Ba, Cs, Cr, Co, Ag, and Th were determined using the INAA method. Study results revealed considerable variation in the particle size distribution and chemical composition of bottom sediments. In broad terms the dominant grain size is >0.1 mm. Two other fraction sizes account for roughly equal proportions of the rest, i.e. 0.1-0.02 mm and <0.02 mm. As concerns overall composition, SiO2 dominated in samples, particularly those where loss on ignition was low. Bottom sediments in the lakes varies in chemistry and pollution levels. The scale of pollution is illustrated by the range of variability of average contents of trace elements in the bottom deposits, e.g.: As (7-63 mg•kg-1), Ba (262-1;630 mg•kg-1), Cs (1.6-134.0 mg•kg-1), Zn (83-3;720 mg•kg-1), Pb (28-731 mg•kg-1), Cr (22-146 mg•kg-1), Cd (0.5-50.3 mg•kg-1), and Cu (9- 197 mg•kg-1). The deviations from geochemical background standards found in the bottom sediments of the water bodies examined make them exceptional on a global scale.},

In terms of biodiversity, the high-mountain ecosystems of Central Asia include the most valuable areas in the world called as hotspot, and also are exposed to intense human pressure causing the destruction of habitats. Vegetation landscapes of Fann Mountains are very diverse because of high-mountain character of this area, local climatic conditions, topography and habitats. That differentiation leads up to biodiversity and formation of unique plant landscapes and endemic species. The vegetation landscapes in altitude order are represented by forbs meadow steppe, thymes, swamp, broad-leaf forest, juniper forests, flood-plain small-leaved forest, tugai, light deciduous forest, pistachio, forbs wormwood, almond, rare vegetation with cushion-shaped species, wormwood eurotia, steppe, thorny grasses with shrub-steppe, rocks and taluses with rare vegetation alpine zones. High level of endemism in Fann Mountains is connected to natural conditions such as geological structure, relief, high-mountain ranges and climate conditions. This fact has an influence on forming mosaic biotops, often isolated by orographic barriers.},

Using the INAA technique, concentrations of the following elements have been determined in common reed tissues: As (0.01-0.69 mgkg -1), Ba (6.0-62.0 mg kg -1), Br (2.5-71.5 mg kg -1), Ca (0.2-1.2%), Co (0.1-1.7 mgkg -1), Cr (0.2-1.7 mgkg -1), Fe (0.01-0.02%), K (0.7-2.9%), Na (235.0- 2910.0 mgkg -1'), Sb (0.05-1.16 mgkg -1), Zn (20.0- 250.0 mg kg -11). Using the INAA and ICP XRF techniques, the overall chemical composition of the substratum sediments on which P. austral grows and the elements they contain, has been determined. Results of common reed tissue analyses are highly varied and only reflect the fertility of the water environment and of the accumulated sediments on which P. austral is developed to a small extent. In many cases the samples also fail to reflect the pollution found in the water or substratum sediments. It was determined that within the water bodies examined, Phragmites austral is mainly forms singlespecies stands of the Phragmitetum austral is association. Its strong dynamics and high bioproductivity as well as the varied numbers of specimens present in different environments make the common reed to some degree a quantitative bioindicator and a mixed type bioindicator.},

The investigation involved field studies and laboratory analysis. The results show tliat the accumulation of nutrients is strongly linked to the plant canopies (Corg - 1.76%; Nt - 0.095) whereas, in the spaces between bushes (Corg - 0;68-1;54 %; Nt - 0;0-16), nutrient accumulation barely takes place. Enriched zones situated under the bush canopies, reflecting interaction between biotic andabiotic factors, are termed fertility islands. Vegetation also colonises the areas aroundtree trunks. Developing soil horizons under the canopies are termed soil islands. In these, organic horizons and sub-horizons create conditions advantageous to the development and existence of organisms which also influence the soils there. Considering the young ageof the soil, and the weak differentiation of soil horizons, the organic mailer that lies directly over the mineral layer plays an essential ecosystem role in the primary stages of vegetation-soil succession. Amount and quality of organic matter influence absorption capacity and cation numbers. The significance of alkaline cations (Ca2+; Mg12+; Na & K) in the composition of broad-leaved species leads to a decrease in soil acidity.},

A comparison of occurrence and diversity in composition of organic compounds in plant tissues and humus horizon of soils under the communities of coniferous forest series in the initial stages and phases was carried out. A large diversity of organic compounds under Algae-Cyanophyta communities, biological soil crusts and Polytrichum piliferum was noticed. A clear differentiation in the composition of the soil organic matter at different phases of succession under predominating communities with cryptogamous and vascular plants was observed. The analysis of organic compounds in plant tissues was found to facilitate the determination of origin of various groups of organic compounds in the soil. The results obtained from the Curie point pyrograms in the humus horizon (A) under grasses (Corynephorus canescens; Koeleria glauca) differed from the pyrolysates obtained under Algae-Cyanophyta communities. The polysaccharide derivates are more frequent in the pyrolysis products under algae, grasses (Corynephorus canescens; Koeleria glauca) and mosses than under Pinus sylvestris. In the beginning of the terminal stage of succession, lignin, phenols and aliphatic substances, prevailed over the polysaccharide derivates in the humus horizon. © 2010 Pleiades Publishing, Ltd.},

Investigations were carried out in the Kuznica Warezynska sandpit, located in the Silesian Upland in southern Poland. Results obtained indicate that at uncovered sands, due to exploitation in unreclaimed places, spontaneous regeneration of vegetation-soil cover occurs. In the succession series observed in the excavation, 3 stages were distinguished (primary; secondary and terminal), which were divided into 6 phases. The oldest observed succession stage was made by communities from the Dicrano-Pinion connection. The duration of succession of the oldest surfaces is estimated at 25 years. Considering morphology, the forming soil differs at every succession stage. In respect to observed soil formation processes, advancing soils, even the oldest surfaces, have initial character; they are poor in nutrients and characterized by acidic, slightly acidic to alkaline pH-reaction. Physico-chemical properties of soil, forming in the area of the sandpit, are conditioned most of all by the ground water level, its chemical composition and the duration of succession. Investigations proved that the course of succession at habitats fed mainly by waters, originated from the seepage of waters of deep circulation, and this differs from this those in places fed by the precipitation of waters. These differences appear most of all in the first phase of optimum stage. The sandpit is also characterized by a large differentiation of vegetation, resulting from the mosaic character of habitats. Habitat differentiation of the sandpit bottom is connected with its diversified relief and hydrogeological situation.},

abstract = {The Błędów Desert in the southern part of Poland is an extensive area of sands and gravels. The origin of the desert had nothing to do with climatic conditions: The effective cause was the development of a major mining and metallurgical industry that started in the 13th century. The surrounding forests were the main fuel source for the industry. In second half of the 20th century, the ca. 18 sq km desert was one of the largest inland areas of blown sand in Central Europe. Based on the analysis of maps from 1804, 1911, 1914 and 1933 and of aerial photographs taken in 1955, 1973 and 1996, changes in the landscape of the Błędów Desert area and in the outline of permanent and drift sands were estimated, as was the gradual overgrowth of the area. The study shows that over ca. 200 years, the vegetation succession in the desert occurred in primary and secondary ways and that it can be divided into 9 phases that are grouped into 3 stages. The primary succession took place in areas covered by loose, bare sand, the secondary succession in areas with remnants of fossil soils. The essential ecological and environmental importance of an initial phase involving algae and cyanobacteria was investigated. This involvement facilitated colonisation by species with high ecologicalrequirements through the fixing of loose sands, moisture absorption and the retention and improvement in edaphic conditions. Up to now, such a phase has not been described in terms of species composition and habitat, but this was done in this study.},

Species that colonize such regions form propagation cores of vegetation through the spread of secondary roots.

abstract = {Phytogenic hillocks are landforms typical for areas built of blown sands. They occur in desert areas with hot and dry (desert) climate as well as in sandy areas in moderate humid climate. They are an effect of cooperation of wind with bushy vegetation of specific features. Under natural desert conditions they are created at e. g. participation of tamarisks and they can reach the height of 6-7 m. In moderate climate, e. g. in area of seaside dunes they are formed at participation of other species and reach decidedly smaller heights. They can also originate in areas of blown inland sands, which were uncovered owing to human activity. One of such areas is located in Silesian Upland in southern Poland (so-called Bledow "Desert"), which beginning goes back to the Middle Ages. It is connected with deforestation, mainly for the needs of contemporary lead, silver and zinc metallurgy. Presently this area is covered in result of intentional vegetation introduction as well as by natural vegetation expansion and succession. One of species intensively entering into this area is Salix arenaria. And just at participation of this bushy willow in deflation areas very characteristic phytogenic hillocks of heights reaching up to 1,5 m are here created using more humid clayey insertions of substratum. They are an effect of these bushes covering up, thanks to which this plant spreads and creates larger and larger landforms. In area discussed it is possible to observe different development stages of phytogenic hillocks-from initial through mature to disappearing ones. The oldest from them were started to create in the period 1973-1976, wherefore the youngest-in the years 2000-2002. The age of hills was determined on the base of dendrochronological analysis. These hills have different shapes and heights, which are conditioned by the intensity of aeolian processes. It is possible to state that phytogenic hillocks of so-called Bledow "Desert" are created by natural physicogeographical processes but conditions for their development were prepared by human being. Thus they are the effect of indirect anthropogenic activity. © 2009 Gebrüder Bornraeger.},

abstract = {Robinia pseudoacacia is a North American species and in Poland it is currently invasive in character. It is used to recultivate sand excavations and others, most often in order to make the process of plant and soil succession more advanced. It has been observed that in places were R. pseudoacacia dominated in plan-tations, the herbaceous vegetation under the trees is poor and sometimes other vascular plants are not appearing at all. Plants usually overgrow the space out of the canopy shade. The positive influence of R. pseudoacacia on a habitat is primarily connected with the chemical composition of plant litter, as well as with the biology of the species. Chemical composition of R. pseudoacacia litter has been researched. The greatest accumulation of elements has been observed in the following parts: green leaves (Ca > K > Mg > P > Si > Na > Fe > Zn > Al > Mn) and leaf litter (Ca > K > Mg > Si > Fe > P > Na > Al > Zn > Mn). Similar regularities are observed in the remaining litter of R. pseudoacacia. It must be emphasized that nitrogen occurs in similar quantities in particular samples and it varies from 1.01 to 2.65%. The plant litter reaction (pH) vary from acid to weakly acid. In a short period of time under the canopy of R. pseudoacacia a 10 cm organic and humus horizont (O/A) has developed. © 2009 Ecological Society of China. Published by Elsevier B.V.},

abstract = {There are no stages of soil cover development in which cyanobacteria and algae do not participate. The degree of algae distribution on the ground and in the soil profile varies. As a result, the role of algae at particular stages of soil development and in different soils is differentiated. The most obvious and significant role of algae is connected with the process of rock weathering and primary humus formation on purely mineral substrata. The research work consisted in determining the species composition of soil cyanobacteria and algae and their role in sand colonisation and soil development. Occurrence of 11 species of cyanobacteria and algae was recorded in the Pustynia Błȩdowska desert area (six Cyanophyta; one Bacillariophyceae; four Chlorophyta (3 taxa; 1 sp.) in 2001 and 2002. The physico-chemical properties of the soil varied under different communities of cyanobacteria and algae. The highest contents of Nt; Corg; available P and exchangeable cations such as Ca2+; Mg 2+; Na+; K+ were observed under Cylindrocapsa sp. cover. Microscopic examinations revealed the existence of intricate filament nets composed of cyanobacteria and algae; which connect mobile sands and intercept the finest mineral fractions carried by the wind. Sand stabilisation by algae contributed to the initiation of soil forming processes.},

abstract = {The influence of fluvial processes in a meandering river to riparian black alders form-growth, Mala Panew River, Silesian Lowland The Maia Panew is a meandering river that flows for 20 km through a closed forest. The bottom of the valley is covered by sands of different grain size and the channel migrates laterally about 0,5 m/ year. Therefore, riparian alders are under the influence of bank erosion and their growth-forms are evaluated. Black alders growing on undercut banks are mostly leaned and their stems are bent, usually having exposed root systems. Clumps of alders growing on the concave banks number several stems, the stems are 1/3 less in diameter than alders growing near straight or convex banks. The clumps growing on banks shaped by erosion are protruding in the middle of the river channel. Alders produce clumps with extended root systems because this helps the plant to obtain stability in opposite to individual stems. Numerous alders growing along straight banks have exposed roots systems and strongly bent stems to take shape of a hook. The stem hooks are formed due to long-term erosion around their root systems. As a result of this process, the stem gradually bends under its own weight in the conditions of laterally stable channel. The alders growing at a distance of 5-15 meters from convex banks often have similar shapes to the trees present on the straight and concave bank. The similarity is caused by progressive lateral erosion and apparent movement of tree lines away from a channel bank.},

Initially, the area around the base of S. acutifolia is colonised by cryptogams. Then, soil formation takes place as S. acutifolia grows and the canopy develops. As a broadleaved species, S. acutifolia produces a lot of biomass. Good habitat conditions are created for the development of micro-organisms accelerating the process of leaf decomposition and humus formation. This encourages the subsequent entry and growth of vascular herbs under the canopy of S. acutifolia, which hasten the process of soil and plant succession. After 5 years, a large number of Pinus sylvestris seedlings develop under the S. acutifolia canopy. P. sylvestris outcompetes S. acutifolia for nutrients and eventually eliminates S. acutifolia from the site by contributing to soil acidification. P. sylvestris then becomes the dominant influence on the physico-chemical properties of the soil.},
