“…Nowadays, the intense use of natural resources and the supply of industrial waste and other types of pollutants produced by human economic activities provoke changes in ecosystems. Most of deleterious substances supplied into water bodies are poorly decomposed and exert a bad effect on fish population [1], [2], [3], [4], [5].…”

The composition of the fish population of three water bodies in the Kenti River system (White Sea basin), polluted by waste from a mining concentration plant, was analyzed. Only four out of 12 fish species of the Kenti River system (pike, burbot, bleak and roach) occur in all the water bodies studied. The fish population is dominated by roach. Smelt and dace were shown to be most sensitive to industrial waste. The closer to the source of pollution, the smaller the number of fish species in the lake. The impoverishment of the fish fauna is largely due to its (alkaline) habitat and the loss of spawning and growing conditions for juveniles (small areas occupied by aquatic vegetation).

“…Recent anthropogenic introductions have altered ecosystems and have threatened biodiversity. Thousands of scientific publications have demonstrated their harmful economic effect and destructive consequences for terrestrial, marine, and freshwater ecosystems [35][36][37][38][39]. Many intergovernmental documents, such as the Convention on Biological Diversity, warn of biological invasions and their consequences.…”

“…Many intergovernmental documents, such as the Convention on Biological Diversity, warn of biological invasions and their consequences. It is obvious that biological invasions and the mixing of faunas are international problems, as the invasive species do not recognize international borders [38,40]. Some of these introductions are "cryptic", defined as "the introduction and spread of non-native lineages within the species' native range (intra-specific cryptic invasion) or the invasion of non-native species that goes unnoticed due to misidentification as a native or another invasive species (inter-specific cryptic invasion)" [41].…”

Biotic introductions are an ongoing disruption for many ecosystems. For passively dispersed freshwater zooplankton, transcontinental introductions have been common but are poorly studied in the southern hemisphere. Here we assess the hypothesis of recent introduction for populations of the Chydorus sphaericus group (Crustacea: Cladocera) in Australia. We analyzed 254 sequences (63 original sequences) from the cytochrome oxidase I region of mitochondrial DNA of Chydorus sp., which included global representation. Three Australian populations were connected with separate clades in the northern hemisphere, suggesting multiple colonization events for Australia. The timescale of the divergences was consistent with recent (Quaternary) dispersal. As Australian populations are exposed to migrating birds from the northern hemisphere, both avian and anthropogenic sources are candidates for dispersal vectors. We concluded that recent cross-hemisphere dispersal in the Chydorus sphaericus group is more common than previously believed.

“…The degradation of biotopes and ecosystems has been shown to be directly related to various human economic activities [1], [2], [3], [4], [5], [6]. Considerable changes in freshwater ecosystems result from various types of industrial pollution, hydraulic engineering, poorly organized commercial fishing and the acclimatization and selfcolonization by new aquatic organism species.…”

The current state of four water bodies in the upper and middle reaches of the River Kenti system, Western Karelia, affected by long-term industrial potassium-sulphate pollution, is assessed. The upper water body of the system, Lake Kostomukshskoye, is supplied by waste water from an iron mining concentration plant. Lakes Okunevoye, Poppalijärvi and Koivas are located downstream. Analysis of some hydrochemical indices and phyto- and zooplankton communities has shown that as the distance from the pollution source increases, the hydrological regime is stabilized, species diversity increases and the quantitative indices of the biotic constituent of the lake-river system grow. For example, the total mineralization value decreases from 632 дo 45 mg/l, the concentrations of major polluting agents, such as K+ and Na+ ions, decline by an average of two orders of magnitude and the medium reaction passes from alkaline (pН 7.7) to neutral (pН 6.8). The species composition of the phytoplankton varies from 18 to 23 species of six 6 divisions. The number of zooplankton taxa increases from 15 to 24 and average quantitative indices grow from 0.048 g/m3 (1.1 thousand individuals/m3) to 0.368 g/m3 (10.3 thousand individuals/m3), respectively. The data obtained were compared with earlier results.
