This publication serves as a continuation of the inventory of aquatic beetle faunas in the Udmurtiya and Bashkortostan, a summary of which was published in 2020. The known composition of the faunas of the republics at the time of the study consisted of 230 (for Udmurtiya) and 120 (for Bashkiriya) species of aquatic beetles (including Donaciinae and Bagoiinae). The material for the article was the collections carried out in the framework of the study of the macrozoobenthos of rivers, oxbow lakes and temporary waterbidies from 2019 to 2020. Sampling of adults and beetle larvae from substrates submerged in water (stones and wood) was carried out manually. When collecting aquatic organisms in overgrown water bodies and rivers, a hydrobiological scraper was used. Data on the first finds of 5 species from 5 families in the territory of Udmurtiya and 6 species from 4 families in Bashkiriya are given. They are respectively as following: Orectochilus villosus (Gyrinidae), Haliplus confinis (Haliplidae), Rhantus bistriatus (Dytiscidae), Helophorus redtenbacheri (Helophoridae), Limnebius crinifer (Hydraenidae) in Udmurtiya, and Haliplus varius (Haliplidae), Ilybius fenestratus, Hydroporus palustris, Graptodytes bilineatus (Dytiscidae), Helophorus brevipalpis (Helophoridae), Limnebius cf. parvulus (Hydraenidae) in Bashkiriya.

This work presents a list of water beetles of the families Hydraenidae and Elmidae occurring in Kabylia (central-north of Algeria) based on an exhaustive review of literature (1872–2016) and on more than 2126 individuals collected during field campaigns (2013–2015). Twenty-five species belonging to nine genera of Hydraenidae and Elmidae are here recorded from a total of 25 sites. Ochthebius (Ochthebius) bifoveolatus Waltl, 1835 is here recorded for the first time from Algeria; Hydraena leprieuri, Limnebius pilicauda, and Limnius intermedius are new records for Kabylia.                A biogeographical analysis shows that the Hydraenidae and Elmidae from Kabylia are essentially Mediterranean (80%) and Palaearctic (20%) elements. Elements with wider distributions are absent.

Hydrological System

AbstractThe middle course of the Neman River is the habitat of 120 water beetle species. Water beetles were most abundant in the Neman River, its major tributaries and oxbow lakes. They consisted of four synecological groups: rheobiontic and rheophilic organisms, type “a” and “b” stagnobionts. The diverse types of aquatic environments constitute faunal centers which, in addition to the specific and dominant Coleopteran populations, also feature migrational elements. The presence of close relations between the fauna of different environments indicates that they form a single, faunistically integrated hydrological system.

Abstract The subject of this study is to analyse changes in the taxonomic structure and development intensity of phytoplankton and, thus, to determine the diversity of cyanobacteria and algae along with the trophy state of two oxbow lakes in the Wrocław area (south-western Poland). The analysis of samples and data from previous years showed a total of 244 cyanobacteria and algae species within these two lakes. The species composition changed significantly in both of them – there were found 90 species new to the studied flora (37% of current flora) and 74 species which were previously recorded. The diversity of cyanobacteria and algae reflects the conditions in these water bodies and each change in ecological conditions (e.g., anthropological dangers) is reflected by a change in the phytoplankton assemblage structure. Consequently, knowledge of taxonomic diversity is useful in monitoring water bodies to preserve them in good conditions. Both studied oxbow lakes belong to eutrophic ecosystems as evidenced by their phycoflora, which is rich in species characteristic of high-trophy water, and recorded water blooms. The analysis of changes in cyanobacterial and algal assemblages in these lakes was also a basis for determining their trophy and finding it to be progressively eutrophic. Regular phycological studies of Wrocław numerous water bodies are essential and, in the future, will allow us to protect them and to react quickly in case of danger to these ecosystems. It will also allow us to study eutrophication processes in the water bodies that are crucial to the city.

Temporary ponds are specific freshwater habitats in which the characteristic fauna of aquatic organisms is formed. One of the large groups of invertebrates in temporary water bodies is water mites. In this work, water mites were studied in three different types of temporary ponds in the vicinity of the city of Tyumen, Western Siberia. The studies were carried out in two periods with a long time interval between them: in 2008–2010 and 2018–2019. In total, 33 species of water mites from 7 families were identified in the studied ponds. All ponds were dominated by vernal mite species typical for this type of water bodies. Also, they were characterized by similar seasonal dynamics of numbers. The species composition and the number of mites in different ponds varied, which is associated with different physicochemical parameters and the fauna of invertebrates, which served as food objects and hosts for the adults and larvae. Despite the small size and periodic drying of the ponds, the fauna of the mites inhabiting them has changed little over the long period of time that separates the studies. Only in one pond, which became permanent due to the rise of groundwater, significant changes in acarofauna were observed. Considering such constancy of the fauna of water mites of temporary ponds, they can be used as bioindicators of the ecological state of water bodies.

We analysed the occurrence of ostracods in a small river, taking into account all the types of water bodies in the floodplain − these included helocrenes, oxbow lakes, and ponds, as well as the main river channel. The objective of the study was to investigate the variation in ostracod communities and identify those factors determining species distribution. The environmental factors considered were the type of water body, responsible for 17% of the variance, the physical and chemical water properties (29%), and the biotic and abiotic factors associated with the substrate type (23%). Among the factors associated with the substrate, sediment sorting, plant coverage and insolation were the most important. The ostracod fauna of the helocrenes differed from that of the other water bodies in the floodplain. In the water bodies of the Krąpiel valley and in the main river channel, 33 ostracod species were recorded, of which 26 were found in the main river channel. Refugia in the floodplain were the main source of the diversity and abundance of ostracods in the main river channel. The mean density in the main river channel was very low, at 330 indiv. m−2, while in the water bodies of the floodplain it was the greatest, reaching up to 5568 indiv. m−2.

Toxicity Mechanisms

This review summarizes the present knowledge on the toxicity of copper and copper nanoparticles (CuNPs) to various fish species. In previous decades, the excessive usage of metal and metallic nanoparticles has increased significantly, increasing the probability of the accumulation and discharge of metals in various trophic levels of the environment. Due to these concerns, it is important to understand the toxicity mechanisms of metals and metallic nanoparticles before they lead to unhealthy effects on human health. In this review paper, we specifically focus on the effect of metal copper and CuNPs on different fish organs under different physiochemical parameters of various water bodies. Nowadays, different forms of copper have distinctive and specific usages, e.g., copper sulfate is a well-established pesticide which is used to control the growth of algae in lakes and ponds. Deactivating the fungi enzymes prevents fungal spores from germinating. This process of deactivation is achieved via the free cupric ions, which are established as the most toxic forms of copper. Complexes of copper with other ligands may or may not be bioavailable for use in aquatic organisms. On the other hand, CuNPs have shown cost-effectiveness and numerous promising uses, but the toxicity and availability of copper in a nanoparticle form is largely unknown, Additionally, physiochemical factors such as the hardness of the water, alkalinity, presence of inorganic and organic ligands, levels of pH, and temperature in various different water bodies affect the toxicity caused by copper and CuNPs. However, comprehensive knowledge and data regarding the pattern of toxicity for copper metal ions and CuNPs in marine organisms is still limited. In this review, we carry out a critical analysis of the availability of the toxicological profiles of copper metal ions and CuNPs for different fishes in order to understand the toxicity mechanisms of copper and CuNPs. We believe that this review will provide valuable information on the toxicological profile of copper, which will further help in devising safe guidelines for the usage of copper and CuNPs in a sustainable manner.

Long-palped Water Beetles were collected during a taxon expedition in Montenegro which involved citizen scientists, students and taxonomists. The material was collected from springs, brooks, fens and the Tara River, at altitudes between 600 m and 1450 m above sea level, using fine-meshed hand-nets and by manual checking of submerged substrates. The morphological species delimitation was supplemented and congruent with mtDNA sequences mainly obtained in the field using the newly-developed MinION-based ONTrack pipeline. The new species Hydraena dinarica Freitag & de Vries, sp. n. from Durmitor Mt. is described, illustrated and compared in detail to closely-related congeners of the H. saga d'Orchymont, 1930/H. emarginata Rey, 1885 species complex. Five additional species and female specimens of two unidentified morphospecies of the genus were also recorded in the vicinity of Durmitor National Park. New records and the first DNA barcodes for Hydraena biltoni Jäch & Díaz, 2012 (endemic to Montenegro) and H. morio Kiesenwetter, 1849 are provided. Further records of H. nigrita Germar, 1824, H. minutissima Stephens, 1829, H. subintegra Ganglbauer, 1901 and females of two unidentified morphospecies are commented upon. The resulting inter- and intraspecific genetic distances and some observations of low or zero sequence divergence between recently-diverged species of Hydraena Kugelann, 1794 are briefly discussed.
