In most colonies, relatively light phenotypes prevailed: most often P00000, less often Y00000 or Y00300. In total, more than a third of the collected specimens had the phenotype P00000. Great variability of the phenotypic and genetic structure of this introduced species in the study area was demonstrated, which usually does not have a clear connection with the locations of colonies or with the shading of habitats. This may be due to both random factors (founder effect, gene drift in recently formed colonies), and the relative youth of the colonies. In the future, the obtained data can be used to monitor possible long-term changes in the phenotypic composition of the investigated colonies to assess the potential effect of selective factors on this composition, first of all, climatic selection outside the natural range of <em>C. nemoralis</em>.</p> N.

Our morphological study showed the similarity between the specimens of <em>S. sarsi</em> found in Kyiv with existing illustrations and descriptions of the Asian population of this species. The most likely route of penetration is human intentional release. Some diagnostic details are discussed and short redescription of species is presented in the paper.</p> L. Svetlichny L.

The significant interpopulation differentiation between populations from different region was demonstrated. The hypothesis of multiple origins of the hybrid form <em>Eusomus ovulum</em>&nbsp;from several parental species was proposed.</p> S. Yu. Morozov-Leonov V. Yu.

Thus, its malacofauna is a nominal standard for the southern water systems of Central Europe. Particular attention is paid to freshwater mussels, which are indicator species and most of which are subject to special protection. During 2009-2011, 50 points of the Danube river basin were surveyed. In 23 of them, seven species of Unionidae were recorded: <em>U.&nbsp;pictorum, U. tumidus</em>, <em>U. crassus</em> s. lato<em>,</em> <em>A. anatina,</em> <em>A. cygnea,</em> <em>P.&nbsp;сomplanatа </em>and<em> S.&nbsp;woodiana</em>, which is an invasive species. The index of occurrence of freshwater mussels in general was 100% in the Lower Danube river (5 study areas), 42% in Tisa river (31 study areas), 33.3% in Seret river (3 study areas), 36% in Prut river (11 study areas). The index of occurrence of species was rather low: 24% of <em>A.&nbsp;anatina</em>, 22% of <em>U.&nbsp; tumidus</em>, 22% of <em>U</em><em>.&nbsp;crassus</em>,&nbsp; 16% of<em> U.&nbsp;pictorum</em>, 14% of<em> P</em><em>.&nbsp;complanata</em>, 14% of<em> S</em><em>.&nbsp;woodiana</em>, and 2% of <em>A.&nbsp;cygnea</em>. <em>U.&nbsp;crassus</em> was not found in the Lower Danube river, while <em>A. cygnea </em>was found only there outside the main watercourse. The invasive species <em>S</em><em>.&nbsp;woodiana</em> occurred in the Lower Danube river and in the sub-basin of Tisa river (with 83% and 20% frequency, respectively. The mean values of population densities ranged from 1.00 (<em>A.&nbsp;cygnea</em>) to 6.14 ind./m<sup>2 </sup>(<em>S.&nbsp;woodiana</em>), and the mean biomass varied from 1.14 (<em>P.&nbsp;сomplanatа</em>) to 797.54 g/m<sup>2&nbsp; </sup>(<em>S.&nbsp;woodiana</em>). In general, the composition of aboriginal malacofauna was stable, with a tendency to decreasing population densities</p> L. Shevchuk L. Vasilyeva M. Taradajnyk S. Mezhzherin Copyright (c) 2021 L.
