abstract = {Biological invasions are one of the greatest threats to biodiversity, economic development, and human health. Therefore an important challenge is to understand the mechanisms and factors that facilitate the spread of invasive species. The Ponto-Caspian polychaete Hypania invalida is one of the invaders that have been colonizing the river systems in Europe since the 1950s. The research aim was to map the distribution of H. invalida in the upper Oder and associated aquatic environments, to assess the contribution of H. invalida to the benthic fauna, to identify environmental factors linked to the occurrence of H. invalida, and to provide genetic markers that can be used to identify H. invalida and monitor its dispersal. H. invalida was found at two sites in the canalized section of the upper Oder and one site at the initial section of the Gliwice Canal. It was found at low abundance and coexisted with other alien macroinvertebrates. H. invalida was not recorded in any smaller river, whether natural, semi-natural, or anthropogenically modified. Apart from the watercourse width, no significant relationships between this polychaete and habitat drivers were found. Genetic analysis showed that the amplified cytochrome c oxidase subunit I and 18S gene fragments showed no sequence variation across all analyzed specimens. Further research is needed to follow the spread of H. invalida in the upper Oder River catchment, as at high densities it can adversely affect inhabited ecosystems. © M.

abstract = {Background: Secondary salinity of river water reduces the value of ecosystem services, negatively impacting the entire aquatic ecosystem and reducing the possibility of water use. In Poland, significant anthropogenic salinity of rivers and water reservoirs is usually associated with mining activity consisting of pumping salty mine water into settling ponds or often directly into rivers. However, to assess the reasons for the salinity of the Vistula waters, it is necessary to identify all sources of salt in surface waters, enabling the assessment of the salt load in the waters. Methods: The paper presents four sources of data which have been compiled to propose a valuable method for analyzing the threat of the river. Patrol monitoring was one method of data acquisition, and State Environmental Monitoring data ware also used. Clustering and correlation statistical techniques were used for analysis. Results: Of the 20 physical and chemical parameters analyzed, chloride, calcium sulphate and magnesium ions are important for salinity. Measurements with multi-parameter probes allowed for the identification of increased salinity pressure sites, while flow analyses were required to calculate the load. Conclusions: The Vistula River had the highest concentrations of the analyzed ions in the Silesia Region. The use of patrol monitoring can be highly useful in determining the causes of emerging problems with water quality and supporting State Environmental Monitoring. © 2023 by the authors.},

abstract = {Beaver-created ponds constitute an important element of small water retention in forest catchments and preserving biodiversity as breeding sites for vertebrates and invertebrates. In many areas, these habitats disappear as a result of drainage melioration, drainage formed from agricultural and developmental needs, and liquidation by littering and backfilling. This study was carried out from 2017 to 2019 to understand the transformations of river valley as a result of the beaver activity in the context of newly created ponds and mountain stream and to assess the changes and biodiversity. Beavers modified in-stream habitat by constructing dams, thus creating a series of interconnected dam ponds. Organic matter retention was higher in beaver ponds relative to unmodified river section. In beaver ponds, the invertebrate aquatic assemblages was highly variable. A total of 56 taxa were identified, and significant seasonal variability of benthos assemblages. The values of diversity indices confirmed the instability of benthos assemblage in beaver ponds (variability of species amongst years and sites), which may be related to the short period of their existence. Lotic macroinvertebrate assemblages were common in the beaver-modified section of stream, with some lentic taxa also being present. The unmodified section of stream had more abundant collectors- gatherers and predators and no filter feeders, while scrapers were more abundant in modified section. The environmental variables which significantly influenced invertebrate occurrence were pH, nitrates, iron and the content of organic matter. The results contribute to ecological characteristics of these aquatic environments, and enable determining their functioning in forest areas. © 2023 European Regional Centre for Ecohydrology of the Polish Academy of Sciences},

abstract = {In Natural Landscape Complexes and Ecological Sites, local environmental protection is used to cover previous industrial activities, fragments of the cultural landscape, and habitats of both vertebrates and invertebrates. In water bodies within the different types of habitat protection, aquatic invertebrate fauna was studied to investigate whether it is a general rule that different forms of protection ensure the diversity of aquatic invertebrates in rural and industrial areas. The research revealed differences between invertebrate assemblages within complexes and between reservoirs. Compared with unprotected reservoirs located in the same area, in the majority of the studied water bodies, either no alien species were found or their relative abundance in assemblages was very low. Significant differences in the density, the number of taxa, the diversity, and the percentage of alien species were observed between different geographical locations. The location of water bodies within the protected area plays an important role in maintaining benthos diversity in industrial areas. These findings are useful for comparison with those of future research to document possible improvements or ongoing ecological regression in the quality of aquatic ecosystems in industrial areas. This study can help guide revisions of protected habitat networks for adequate protection of freshwater biodiversity in industrial areas. © 2022 by the authors.},

abstract = {Many regions of the world are industrialised and urbanized like the Upper Silesian Coal Basin (USCB), which is located in one of the most industrialized areas of Europe. Due to the presence of coal and other mineral deposits and their excavation, this area is subject to extensive industrialization, including the functioning of mining and metallurgy industries. According to the Water Framework Directive, water released from mines contains a wide range of pollutants and hence poses a serious threat to the ecology of river systems, eventually resulting in their degradation. The aim of this study was to assess the ecological status of rivers located in the Vistula and Oder river basins, which are affected by the coal mining industry. In this study, macroinvertebrates were used as biological response on the water pollution, and were collected at 30 sampling sites in 12 rivers following the methodology of monitoring studies. The results revealed major differences in the parameters related to river salinity and nutrient loads in the studied rivers. Only the two rivers, Żylica and Liswarta, showed good ecological status, while bad ecological status was recorded for Bierawka, Rawa, Łęgoń, and Biała Przemsza rivers. A redundancy analysis of the results indicated the following: the quality class was positively related to the degree of conductivity; the density of macroinvertebrates was positively related to a higher content of N-NO2 (Nitrite nitrogen) and EPT (The number of families from Ephemeropthera; Plecoptera and Trichoptera), ASPT (average score per taxon PL), and 1-GOLD (abundance of Gastropod; Oligochaeta; and Diptera) indices were positively related to a higher content of dissolved oxygen. The condition of water and benthic invertebrates was significantly influenced by the industrial catchment, which was apparent from the ecological status of the studied systems. The rivers in the most industrialized part of this area were found to be characterized by worse conditions. © 2022 The Authors},

abstract = {Springs are unique aquatic environments that support specific biota, including endemic species and rare species listed in Red Lists. Due to their usually small size, springs are highly sensitive to disturbance. Many of them are threatened by aquifer depletion, contamination, surface-water diversion, livestock trampling, recreation, and invasive species. The aim of this study was to assess the colonization success of the invasive New Zealand mud snail (Potamopyrgus antipodarum) in a cold spring ecosystem in southern Poland. In Europe, this species has recently been added to the top “hundred worst” alien species due to its impact on invaded ecosystems. The study was carried out in two areas of the spring ecosystem—in the springhead and the springbrook—over a four-year period. Potamopyrus antipodarum dominated the benthic macroinvertebrate communities in both areas of the spring ecosystem. Nevertheless, its abundance in the springbrook was significantly greater, and increased noticeably during subsequent years compared to that in the springhead. The populations of P. antipodarum were exclusively composed of females. Smaller-sized New Zealand mudsnails were more abundant near the spring’s source than at the second site. The females at the springhead became fecund at sizes as small as 3.7 mm (the number of embryos was between 0 and 37), while at the springbrook, embryos were found in snails as small as 3.4 mm (the number of embryos was between 0 and 42). Our results suggest that the lower water temperature at the spring-head may limit the population size of P. antipodarum, thus making its density too low to be able to affect the community structure of benthic macroinvertebrates, including the spring snail Bythinella cf. austriaca. © 2021 by the authors.

abstract = {Apocorophium lacustre (Vanhoffen; 1911), which is a native brackish amphipod species of the North Atlantic and Baltic coasts, was recorded in the upper Oder River for the first time in 2017. Before that, only alien amphipod species had been found in this area. The aims of the study were to describe the distribution pattern of A. lacustre in the upper Oder River catchment, to investigate the composition and structure of the amphipod assemblages against the background of the habitat conditions and to provide a genetic identification of the species using DNA barcodes. In total, 16 sites were studied. A. lacustre was recorded in 14 of them. It was not found at one site in the Oder River and at one location in the lower Klodnica River. A. lacustre outnumbered the other amphipods in the Oder, in the mouth section of the Klodnica and at one site in the Gliwice Canal. The alien species Gammarus tigrinus (Sexton; 1939) was dominant in the amphipod communities at the southernmost site in the Oder River, in the Klodnica Canal, and at most sites along the Gliwice Canal. In the Klodnica River, another alien species, Dikerogammarus villosus (Sovinsky; 1894), was dominant in the amphipod fauna at two sites. Though the density of A. lacustre was high in the Oder River, it was much lower in both the canals and the Klodnica River. In our study, the depth and river velocity both contributed to the distribution of this species. © 2020 Wiley-VCH GmbH},

Such data are missing from Central Europe, and therefore, the presented study was performed in inland anthropogenic ponds with different salinity levels located in the second largest European hard coal basin. The researcher indicated a positive correlation between water salinity and the biomass and density of macrozoobenthos as well as the percentage of shredders and the abundance of alien species, whereas there was a decrease in taxa diversity and richness and the abundance of filtering and gathering collectors and predators along with increasing salinity. The survey showed that a high level of nutrients and organic matter were also significantly correlated with the distribution of the macroinvertebrate taxa and functional feeding groups. The conducted research confirmed that mining salinisation acts as a strong filter that shapes the biodiversity because it affects the composition, abundance, biomass and functional traits of benthic macroinvertebrates and significantly contributes to the invasion of alien species. © 2020, The Author(s).},

Earlier research has focused on macroinvertebrates including oligochaetes in anthropogenically saline rivers and streams, but studies on oligochaetes in anthropogenically saline stagnant waters remain scarce. Therefore, this study was conducted to assess changes in the species composition as well as the abundance and biomass of oligochaete communities along a large salinity gradient in the anthropogenic inland water bodies located in the Upper Silesian Coal Basin (Southern Poland), which is one of the largest coal basins in Europe. Herein, a total of 27 oligochaete species including five alien species were assessed, namely, Potamothrix bavaricus, Potamothrix hammoniensis, Potamothrix moldaviensis, Psammoryctides albicola, and Psammoryctides barbatus. The results confirmed that the freshwater oligochaetes could tolerate elevated water salinity and showed highest densities and taxa richness in intermediate salinity. Moreover, the waters with the highest salinity had an extremely low number of oligochaete species. A salinity level above 2800 mg L-1 led to significant loss of diversity of the oligochaetes, and consequently, these habitats were colonized by halotolerant species, especially Paranais litoralis, whose abundance increased with increasing salinity gradient. © A.

Until now, 111 annelid taxa (mainly oligochaetes) had been identified in underground waters in Poland, with higher numbers (71) in the interstitial habitat than in stream bottoms (62). The number of species identified in the caves and wells was distinctly lower (54 and 29; respectively). The Correspondence Analysis did not separate the samples from various underground water types into distinct groups, and the distribution of well fauna was especially scattered (in the ordination diagram) because abiotic parameters differ strongly in studied wells. Only three stygobiontic species (Cernosvitoviella parviseta; Enchytraeus dominicae and Trichodrilus moravicus) were related to some caves.

The objectives of the survey were to analyse the structure of the macroinvertebrate communities in the Bolina River, which is currently the second most anthropogenic salinised river in the world, in relation to various types of instream microhabitats and to determine the environmental factors that have a significant effect on the structure of the macroinvertebrate communities. The result of a canonical correspondence analysis (CCA) showed that electrical conductivity, the temperature of the water and the organic matter content in the bottom sediments were the most important factors (statistically significant) that influenced the macroinvertebrate communities in the anthropogenic salinised river. A total of 77 taxa of macroinvertebrates were recorded in the Bolina River. A Kruskal-Wallis one-way ANOVA and multiple comparison post hoc tests revealed statistically significant differences in the median number of taxa and the median density of macroinvertebrates between the various types of microhabitats in the salinised river. The anthropogenic salinisation of a river can lead to a decrease in aquatic biodiversity that favours invasive species over native species. The Bolina River, which has a salinity of up to 33.6‰, is an example of a unique habitat for organisms that are salt tolerant (euryhaline) or eurytopic. It is a route for the spread of alien and invasive invertebrate species including Gammarus tigrinus, Potamopyrgus antipodarum, and Monopylephorus limosus. © 2019, Springer Nature Switzerland AG.},

abstract = {Anthropogenic salinisation of freshwater ecosystems is frequent across the world. The scale of this phenomenon remains unrecognised, and therefore, monitoring and management of such ecosystems is very important. We conducted a study on the mollusc communities in inland anthropogenic ponds covering a large gradient of salinity located in an area of underground coal mining activity. A total of 14 gastropod and 6 bivalve species were noted. No molluscs were found in waters with total dissolved solids (TDS) higher than 17.1 g L−1. The share of alien species in the communities was very high in waters with elevated salinity and significantly lower in the freshwaters. Canonical correspondence analysis (CCA) showed that TDS, pH, alkalinity, nitrate nitrogen, ammonium nitrogen, iron, the content of organic matter in sediments, the type of substrate and the content of sand and gravel in sediments were the variables that were significantly associated with the distribution of molluscs. The regression analysis revealed that total mollusc density was positively related to alkalinity and negatively related to nitrate nitrogen. The taxa richness was negatively related to TDS, which is consistent with previous studies which indicated that a high salinity level is a significant threat to freshwater malacofauna, causing a loss of biodiversity and contributing to the colonisation and establishment of alien species in aquatic ecosystems. © 2019, The Author(s).},

abstract = {Sinkhole ponds originated as a result of human activity leading to ground subsidence and create important habitats for the diversity of benthos fauna in urban areas. The objectives of this study were to determine whether the context (roadside/forest) is important in relation to the composition and diversity of macroinvertebrates, and to evaluate the influence of environmental factors (e.g. water quality) on snail communities. The study showed that the context of ponds had an impact on the properties of the water. Ponds located along roads were characterised by higher conductivity and a higher concentration of calcium and phosphates. The fauna was composed of 47 taxa, including 26 taxa found in both pond contexts. The density of macroinvertebrates was higher in forest ponds. CCA analysis showed that conductivity and concentration of nitrates were most strongly associated with the distribution of gastropods. Alien snail species more often inhabited the roadside ponds. © 2018, © 2018 Landscape Research Group Ltd.},

The widgeon grass creates underwater meadows in the shore zone of the settling pond and it grows in dense communities together with the common reed Phragmites australis in the coastal zone. Apart from these two plants, no other species were found. The morphological features of the vegetative and generative organs of the studied population of R. maritima is similar to those that have been reported from Europe. The bottom of the pond is atypical for R. maritima-it is covered by mine waste. The water of the settling pond has a high salinity and the water chemistry corresponds to the more natural environments that are inhabited by widgeon grass. This substitute habitat, which imitates the natural environment of R. maritima contributes to the good development of these species. However the studied settling pond offers unstable conditions due to the ongoing mining activity and requires permanent monitoring. © 2018 E-flow BioOne. All rights reserved.},

In our study, B. sowerbyi was found on one site (108 km of the river course) that is located more than 400 km from its previous recordings in the Oder River. This finding may show that B. sowerbyi has spread upstream.

abstract = {Older observations, which were based solely on light microscopy, suggested that the main stages of oogenesis such as yolk uptake, take place outside the ovary, i.e. in the body or the ovisac cavity in some groups of clitellate annelids. Such extraovarian oogenesis was observed in naidines (Naidinae). Because there are no current data about the ovary organization and the course of oogenesis in Naidinae, we analyzed female gametogenesis in three common representatives of this taxon – Stylaria lacustris, Chaetogaster diaphanus and Ripistes parasita – using light, fluorescent and transmission electron microscopy. We found paired and inconspicuous ovaries only in S. lacustris. These ovaries were made up of four to five syncytial cysts that are composed of oogonia and germ cells, which are synchronously entering meiotic prophase I. The cysts were enveloped by thin somatic cells. No growing oocytes were observed within the ovaries. However, as many as five freely floating germ-line cysts, each clustering about 30 germ cells surrounded by flat somatic cells, were observed within the ovisacs in all three of the species studied. The germ-line cysts that were found in all of the naidines studied had an architecture that is typical for clitellate annelids, i.e. each germ cell was connected to a common and anuclear cytoplasmic mass, the cytophore, via one intercellular bridge. Within these cysts, two morphologically different categories of germ cells arose. One cell usually continued meiosis, gathered nutrients and became the oocyte, whereas the rest of cells did not continue meiosis and did not gather a yolk – these cells appear to supply the oocyte with cytoplasm and cell organelles and are regarded as nurse cells. Generally, as in other microdriles, the species studied produced large, yolky oocytes. The details of oogenesis and oocyte organization are similar to other oligochaetous clitellates that have been studied. Interestingly, peculiar organelles, which are called accessory nuclei, have been found within the perinuclear cytoplasm of Ch. diaphanus vitellogenic oocytes. However, their molecular composition, functions and fate are unknown. The results obtained unequivocally show that in the naidines studied, the majority of oogenesis takes place outside the ovary, i.e. most of oogenesis is extraovarian. For comparative purposes, we propose the term “an ovary of the Stylaria type” to describe the type of extraovarian oogenesis in which polarized germ-line cysts develop freely within the ovisac cavity. © 2016 Elsevier GmbH},

The anthropogenic impact on the quality of water was revealed in some wells in both areas, which resulted in relatively low fauna diversity and abundance in polluted wells. Canonical correspondence analyses suggested that depth, age, sediment organic matter content, water oxygenation, and conductivity best explained the variance in the distribution of benthic fauna taxa. Among the 19 taxa that were determined to the family level, oligochaetous Clitellata dominated. They were represented by 13 species and one genus. Among them, two stygobionts, Trichodrilus moravicus and Rhyacodrilus subterraneus, were determined. Moreover, only one crustacean stygobiont, Niphargus tatrensis, was found, and it occurred only in a single well. A low number and abundance of stygobionts and stygophiles compared with stygoxenes was observed.

In total, 21 oligochaete species were recorded (7–11 in the urban ponds; 11–15 in the woodland ponds). Aulodrilus pluriseta, Aulodrilus japonicus and Ophidonais serpentina were only found in the woodland ponds, while Potamothrix bavaricus only occurred in the urban ponds. Limnodrilus hoffmeisteri, Limnodrilus claparedeanus, Chaetogaster diaphanus and Ophidonais serpentina dominated in the woodland ponds, whereas Limnodrilus hoffmeisteri, Limnodrilus claparedeanus, Potamothrix bavaricus and Tubifex tubifex prevailed in the urban ponds. The total density of oligochaetes was higher in the urban ponds thought the values of the diversity indices were higher in the woodland ponds. The local diversity of the ponds was high, while the among-site diversity made only a small contribution to the regional diversity. Nonetheless, a cluster analysis divided all of the ponds into two distinct groups depending on their location. CCA analysis showed that conductivity, pH, total hardness, alkalinity, the concentration of chlorides and the content of organic matter in the bottom sediments were most associated with the distribution of some oligochaete species among the ponds studied. © 2016, Springer Science+Business Media New York.},

Their rapid expansion is a significant component of the global changes that pose a great ecological impact and a serious threat to the diversity of native fauna. This study documents new localities of occurrence of Sinanodonta woodiana in Poland. We also attempted to determine its density, biomass, morphometric features and age structure. We found that its presence is clearly related to temperature and that the current range of its occurrence in Poland mostly overlaps with the areas with the highest average annual temperatures. The study showed significant differences in mean density between the fishponds: on particular sites the density amounted to 9 individuals/m 2 and their biomass exceeded 3000 g/m 2. ANOVA revealed significant differences in the mean dimensions of the shells between the three fishponds related to their height and width. Seven-year-old individuals were the most numerous while one-, two-, five- and six-year-old specimens were the most numerous in pond 2. In our opinion, S. woodiana has created a permanent population that is probably able to breed. This is confirmed by the appearance of one-year-old individuals as well as the other younger age classes. © A. Spyra et al., Published by EDP Sciences 2016.},

abstract = {Capilloventridae are regarded as the putative sister taxon to all other Clitellata. To shed more light on their internal anatomy, we studied the ovary organization and the course of oogenesis in Capilloventer australis. We found that the ovary organization differs substantially from that known in all other clitellate annelids. In contrast to other clitellate annelids, the germ cells in C. australis ovaries develop individually and do not from syncytial cysts. Neither intercellular bridges nor central cytoplasmic mass (cytophore) - structures that are characteristic of gametogenesis in other Clitellata - were found. The paired ovaries of C. australis are located in segment XIII and form chains that are composed of linearly arranged growing germ cells that are covered by a thin envelope of somatic cells. The progression of germ cell development can be observed along the long ovary axis. The ovary tip is occupied by oogonia and below it, previtellogenic and early vitellogenic oocytes occur. Large, vitellogenic oocytes, which are filled with yolk, detach from the ovary and fill the segment lumen. Vitellogenic oocytes are not enveloped by somatic cells. With the exception of the lack of germ-line cyst formation, oogenesis is similar to that found in other Clitellata. It is not clear whether the lack of germ-line cysts is a basal condition for Clitellata that is retained in C. australis or, by contrast, did clitellate annelids inherit a female germ-line cysts from their ancestors and their lack in C. australis is a derived condition? © 2015 Elsevier GmbH.},

abstract = {Studies were carried out in a man-made reservoir that was undergoing restoration using selective hypolimnetic withdrawal (Pławniowice reservoir; Southern Poland). The aim of the research was to assess the changes in the composition of oligochaete fauna in relation to water quality and to estimate whether indices based on oligochaetes may be useful in the assessment of a reservoir’s recovery from eutrophication. Samples were collected in the first, fifth, and eighth year of the restoration during the summer stratification at 22 sites along six transects that covered depths from 2 to 15 m. The results of the survey indicated an improvement in some physical and chemical water parameters in respect to those during the period prior to the restoration measures. The present study showed an increase in the oligochaete diversity and a decrease in their abundance accompanied by a shift toward a larger share of taxa that are characteristic of mesotrophic and oligotrophic conditions. This study detected slow changes in the values of the trophic indices based on oligochaetes toward mesotrophic conditions. Discriminant analysis, performed using stepwise forward selection, demonstrated a good separation of samples from 2004 and 2011 according to trophic condition (TC) and biotic quality index (BQI) indices. The present data shows that metrics based on Oligochaeta may be useful for detecting changes in the trophic status. © 2015, Springer International Publishing Switzerland.},

abstract = {The paired ovaries of Propappus volki are small, conically shaped structures with a narrow end that is connected to the intersegmental septum, while the wide end extends into the coelom. Ultrastructural studies showed that the ovaries are composed of interconnected germ cells that form syncytia and accompanying somatic cells. Each germ cell in a cyst is connected with the central, anuclear cytoplasmic core, the cytophore, via one cytoplasmic bridge. The somatic cells form both a thin ligament that joins the gonad with the septum and also surround the germ cells, thus, forming a thin ovary envelope. The somatic cells that are in immediate contact with growing oocytes, i.e., follicular cells, are more voluminous than other somatic cells. There is a clear gradient in the development of germ cells along the long ovary axis. As a consequence, three zones can be distinguished. In zone I all of the germ cells are in the prophase I of meiosis, while zone II contains undifferentiated germ cells with a similar morphology. In zone III there are two morphologically distinct categories of germ cells - the more numerous but smaller germ cells that are regarded here as nurse cells and several growing oocytes. The growing oocytes gradually accumulate cytoplasm and yolk material and protrude from the ovary into the segment cavity. The late vitellogenic oocytes, which are filled with yolk spheres, lose contact with the gonad and float within the coelom. The comparison of the results that were obtained with the ovary structure and oogenesis in other Clitellata shows that: (1) the pattern of germ-line cyst organization in P. volki and other Clitellata is the same; (2) the course of oogenesis in P. volki is similar to other oligochaetous clitellates and (3) the ovary organization in P. volki is broadly similar to that which has been described in tubificins, brachiobdellids and lumbriculids but which differs significantly from that found in Enchytraeus albidus. © 2015 Elsevier GmbH.},

abstract = {The objectives of the survey were to analyse the structure of the mollusc communities in the mining subsidence reservoirs that were created as a result of land subsidence over exploited hard coal seams and to determine the most predictive environmental factors that influence the distribution of mollusc species. The reservoirs are located in urbanised and industrialised areas along the Trans-Regional Highway, which has a high volume of vehicular traffic. They all have the same sources of supply but differ in the physical and chemical parameters of the water. In total, 15 mollusc species were recorded including four bivalve species. Among them Anodonta cygnea is classified as Endangered according to the Polish Red Data Book of Animals and also as Near Threatened according to the European Red List of Non-marine Molluscs. Eleven of the 15 mollusc species are included on the European Red List of Non-marine Molluscs as Least Concern. Conductivity, pH and the concentration of calcium were the parameters most associated with the distribution of mollusc species. Canonical correspondence analysis showed that Potamopyrgus antipodarum, Radix balthica, Physella acuta, Gyraulus crista and Pisidium casertanum were associated with higher conductivity and lower pH values. A. cygnea, Anodonta anatina and Ferrissia fragilis were negatively influenced by these parameters of the water. The results of this survey showed that the mining subsidence reservoirs located in urbanised and industrialised areas provide refuges for rare and legally protected species and that they play an essential role in the dispersal of alien species as well. © 2015 The Author(s).},

This is a naidid species that is not usually abundant in oligochaete communities. Its ecology and biology is poorly known and thus the aim of this study was to characterise the environmental conditions influencing the occurrence of R. parasita and to assess its population dynamics and life history pattern. R. parasita occurred in a pond with soft water and a low level of mineralisation, a pH ranging from 6.1 to 7.0, and a high content of nitrogen and phosphorus. During our investigation, considerable seasonal changes in the occurrence and population density were detected. Specimens of this species inhabited alder leaf deposits in winter and early spring while in summer and autumn they occupied in large number floating Nuphar lutea leaves. A stepwise regression analysis showed a relationship between the temperature and dissolved oxygen content in the water and the density of R. parasita. The R. parasita reproduced asexually by paratomy (between May and November). The mean doubling time (days) for the population was 22.4. Only a few individuals (less than 1% of the population) matured in September and October. © 2015 Institute of Zoology, Slovak Academy of Sciences.},

abstract = {The ultrastructure of the ovaries and oogenesis was studied in three species of three genera of Tubificinae. The paired ovaries are small, conically shaped structures, connected to the intersegmental septum between segments X and XI by their narrow end. The ovaries are composed of syncytial cysts of germ cells interconnected by stable cytoplasmic bridges (ring canals) and surrounded by follicular cells. The architecture of the germ-line cysts is exactly the same as in all clitellate annelids studied to date, i. e. each cell in a cyst has only one ring canal connecting it to the central, anuclear cytoplasmic mass, the cytophore. The ovaries found in all of the species studied seem to be meroistic, i. e. the ultimate fate of germ cells within a cyst is different, and the majority of cells withdraw from meiosis and become nurse cells; the rest continue meiosis, gather macromolecules, cell organelles and storage material, and become oocytes. The ovaries are polarized; their narrow end contains mitotically dividing oogonia and germ cells entering the meiosis prophase; whereas within the middle and basal parts, nurse cells, a prominent cytophore and growing oocytes occur. During late previtellogenesis/early vitellogenesis, the oocytes detach from the cytophore and float in the coelom; they are usually enveloped by the peritoneal epithelium and associated with blood vessels. Generally, the organization of ovaries in all of the Tubificinae species studied resembles the polarized ovary cords found within the ovisacs of some Euhirudinea. The organization of ovaries and the course of oogenesis between the genera studied and other clitellate annelids are compared. Finally, it is suggested that germ-line cysts formation and the meroistic mode of oogenesis may be a primary character for all Clitellata. © 2010 The Author(s).},

The results of the study showed that the richness of Oligochaeta species is not a good method for estimating the trophic levels of the studied sand pits.

abstract = {Studies were carried out from April 2000 to April 2001 on two mining subsidence pools located in the nature reserve Żabie Doły. Collected worms belong to 14 species and one genus. The most numerous were representatives of the Tubificidae (96% of specimens collected from the 1 st water body and 79.5% from the 2nd) and Naididae (3.3% and 20.4%, respectively). Moreover, in the first pool single representatives of the Lumbriculidae family (0.2% of the collection) and Enchytraeidae (0.5% of the collection) were found whereas in the second, there were only single specimens of Lumbriculidae (0.1% of the collection). Seasonal changes in the abundance of the Naididae family representatives in both water bodies were noted, whereas the number of the Tubificidae was stable in both pools during the study period.},

abstract = {The investigations were carried out in post-exploitation water bodies (subsidence pools, sand- and gravel pits) situated in urbanised and over-industrialised region of Upper Silesia. The least diversified leech (Hirudinea) communities occurred in subsidence pools, because of the very high concentration of chlorides, sulphates and phosphates in their water, which is moreover very hard and of high BOD5 value. In other kinds of studied water bodies greater leech species diversity was observed. Most of the species found in studied water bodies occur commonly in various freshwater habitats, what may point out the lack of peculiarity of leech communities in these unnatural conditions.},
