Stone loach, common minnow, and gudgeon were recorded in more than 50% of the study sites. Common minnow was the most abundant species, contributing 66% of all captures. Elevation, depth, and width of the river were the main environmental factors influencing the distribution of more than half of the studied fish species. Our research in the eastern edge of Europe shows that fish preferences in terms of probability of occurrence, abundance, and niche breadth for environmental factors can vary greatly, even among closely related species. depth.

The development of methods for the isolation and analysis of ancient DNA from archaeological and paleontological remains has made it possible to take a new look at both the presumed core regions of domestication and the geography and dynamics of livestock distribution. This paper discusses the reports on the reconstruction of the migration processes of domestic animals in Eurasia using the analysis of ancient DNA performed by leading specialists from Great Britain, France, Finland, Ireland, and Russia at the international symposium on Domestic Animal Archaeogenomics (Bolgar, Republic of Tatarstan, March 2020). In addition to discussing the demographic history of different species of domestic animals, special attention was given to the development of methods for working with ancient DNA and the p...

The studied region has a high geographical and environmental heterogeneity. The impact of environmental factors on species occurrence was analyzed with generalized linear models. Among the selected fish, sunbleak had the highest probability of occurrence, and bleak had the highest abundance. Elevation was the only environmental variable significantly affecting the probability of occurrence of all three species. With an increase in elevation, the probability of occurrence of bleak, common spirlin, and sunbleak significantly decreased. Optimum values and niche breadth differed significantly between fish species for some of the environmental variables.

Brown trout populations from the middle Volga and upper Ural drainages in the Russian Federation ... more Brown trout populations from the middle Volga and upper Ural drainages in the Russian Federation were analyzed with respect to their interrelationships and phylogenetic status using complete mtDNA control region sequences and 10 microsatellite loci. Among 56 individuals from eight populations (six from the middle Volga and two from the upper Ural drainages) only one haplotype was detected: Iran1 from the Danube phylogenetic lineage. This haplotype is very frequent in the southern Caspian basin in Iran. Given the high diversity of haplotypes in northern Iran, in contrast to the complete domination of the Iran1 haplotype in our study, it seems likely that Iran1 reached the middle Volga and upper Ural drainages as a consequence of colonization from the southern Caspian basin. In contrast to the mtDNA analysis, a more pronounced differentiation was observed among the studied populations on the basis of microsatellite DNA data. Based on this result, it is proposed that each population should be treated as a distinct management unit in the context of future conservation activities.

The complete mitochondrial DNA control region was sequenced and 12 microsatellite loci genotyped. Five previously undescribed closely related haplotypes (Caspian clade) were detected. The Caspian and previously reported Scandinavian clade formed a Caspio-Scandinavian group that was found to be the closest relative to the Balkan clade of European grayling. Based upon the molecular results, paleogeological information and a molecular clock of 0.5% change per million years, it appears the Caspio-Scandinavian group split some 0.6 million years ago (95% HPD = 0.33-0.92 mya), while the Balkan clade separated about 1 mya, in the Pleistocene. The sister relationship between Caspian and Scandinavian haplotypes implies that, at some time over that period, the Caspian basin might have been a corridor for dispersal connecting eastern and northern Europe. Microsatellite analysis revealed relatively large inter-population genetic differentiation among the Caspian sample set, pointing to genetically distinct populations that are deserving of special attention in terms of management and conservation.

In this paper we have explored the entire range of elevational gradients existing in the European part of Russia. We analyzed how fish biodiversity (species richness, abundance, diversity indices) at 435 river sites differed by elevation. The impact of elevation on the distribution of freshwater fish species was analyzed using regression and ordination methods. For the first time for a large area of Eastern Europe, optimum points and niche breadth for fish species along altitude gradients were estimated. Our analyses showed: (1) species richness and Shannon index decreased in the upper part of the gradient; fish abundance showed a unimodal response to elevation; highest numbers were found at elevations between 250 and 500 m; (2) ordination analysis demonstrated an upstream-downstream gradient of the fish assemblages; (3) regression analysis showed significant preferences for elevation by 19 species, all of which were monotonic; (4) optimum and niche breadth (tolerance) were highly variable between species; only five species (brown trout, grayling, common minnow, bullhead and stone loach) were encountered at elevations above 650 m; and (5) in our region, the habitat of grayling was higher in the mountains, and its abundance (numbers) at extreme elevations was greater, than brown trout. These results show how fish assemblages differ with elevation. Our findings identify the data that can be used for regional environmental monitoring of the state of small rivers and for aquatic conservation.
