| Аннотация: | The DNA studies of badgers (Meles sp.) from the right-bank and left-bank areas of the Volga River in the Saratov region are described. Asian badgers (Meles leucurus Hodgson, 1847) inhabit the Left Bank of the Volga River in the Saratov region, while European badgers (M. meles Linnaeus, 1758) inhabit the Volga Right-Bank districts of the region; however, Asian badgers have been found in Khvalynsky district of the Saratov Region in addition to the European badger. Despite the sufficient number of publications devoted to the Asiatic badger distribution in the Vyatka–Kama region and the Volga region and the studies devoted to the development of systematics of the genus Meles in Russia, the question of the boundaries of the ranges of European and Asiatic badgers and the zones of their sympatry (parapatry) in the Volga–Kama region has not been fully investigated to date. Our work is devoted to the study of this question. The analysis of biological material that we have collected has shown that all five of the studied badger individuals from the Saratov Volga region phenotypically look like Asian badgers; however, DNA analysis showed that only two of them were M. leucurus and other three were heterozygous individuals carrying genes from both species and were identified as hybrids. The remaining 29 individuals were captured in the right-bank areas of the region. Samples were taken from badger individuals from the northern to southern borders of the region in the areas located along the Volga River on the Volga Upland and in the Oka–Don Plain. Among them, one individual from Khvalynsky district turned out to be an Asian badger, one individual from Krasnoarmeysky district was a hybrid of these two species, and three individuals, one from Tatishchevsky, the second from Volsky and the third from Khvalynsky districts showed introgression of Asian badger genes into the genotype of European badger. Thus, we have managed to find out that, at this stage of the development of the climatic cycle phase in the Lower Volga Region characterized by warming winters, the Volga River, with its two reservoirs within the Saratov region, is not an absolute zoogeographical boundary and badgers whose species are characterized by winter sleep can under certain conditions overcome, most likely on ice, both the river itself and the lake parts of the Volgograd and Saratov reservoirs. According to the revealed introgression in some individuals from different areas on the Volga Upland of the right bank of the Saratov region, it can be assumed that such traveling across the Volga River took place earlier, possibly before its flow was regulated by dams. | |

| Аннотация: | Ranavirosis is an emerging infectious disease of amphibians, fish, and reptiles caused by large dsDNA viruses of the genus Ranavirus associated with morbidity and mass mortalities worldwide. They are considered to be one of the major drivers of the ongoing amphibian biodiversity crisis. In this study, we investigated the prevalence and genetic diversity of ranaviruses in native and invasive populations of water frogs (Pelophylax spp.) across Russia using the DNA sample collection established in 2006–2016. The collection included samples collected in the wild and samples from wild-caught water frogs that had been kept in laboratories for a period of time. Overall, 52 out of 590 (8.8%) of wild frogs from 18 out of 94 (19.1%) sampling sites tested positive, including samples from invasive populations. Among the captive frogs, 71 out of 263 (27.0%) were positive and they had a significantly higher relative viral load. We found six major capsid protein gene haplotypes from 22 positive samples, all belonging to the common midwife toad virus (CMTV-like) ranaviruses, at multiple sites within the basins of three of Europe's largest rivers (Volga, Dnieper, and Don). Combined with previously published data, this study provides evidence for a continent-wide distribution of CMTV-like ranaviruses in Europe and strengthens the hypothesis of their endemism on the continent. Our study also highlights that the water frogs are important hosts for ranaviruses and could potentially act as vectors for infection transmission. | |

| Аннотация: | The current capacity for the purposeful study of the mammalian fauna of Russia using public databases is discussed. A list of species of Russian fauna compiled under united principles is lacking and the lists of species published in different departments are inconsistent. Systems that can monitor changes in the qualitative or quantitative composition of the fauna are not yet sufficiently refined. The systematization of previously accumulated faunal data requires the involvement of qualified taxonomists. Nevertheless, initial work on the “Mammals of Russia” database, which currently contains 16 512 records on 235 species of mammals, has allowed us to positively assess the prospects for further ordering of faunal information within the country. | |

| Аннотация: | Studying the distribution of morphologically cryptic animal species is always a very difficult task. Because most marsh frog species (the Pelophylax ridibundus complex) are cryptic, we used molecular markers to identify them. Three marsh frog species (P. ridibundus, P. kurtmuelleri and P. cf. bedriagae) inhabit the northern part of Western Palearctic. We created a database of localities and built models of their modern distribution. These models showed that the most suitable habitats are on the north of the Mediterranean region for P. cf. bedriagae, temperate Europe for P. ridibundus, and the Balkan coastal areas for P. kurtmuelleri. The projection of the modern ecological niches under the late-Quaternary climatic conditions showed that the range of P. kurtmuelleri remained largely unchanged during the period, whereas the ranges of P. cf. bedriagae and especially P. ridibundus changed greatly over time. During the Last Glacial Maximum, the presumed range of P. cf. bedriagae covered a relatively large area in the north of the Mediterranean region and the south of European Russia. Glacial refugia of P. ridibundus were apparently located in the northern Balkans, the northern coast of the Black and Azov seas, and possibly in Western Europe. The northward long-distance post-glacial dispersal of P. ridibundus occurred from refugia in the northeastern Balkans and the Black-Azov seas region. Since the Late Pleistocene, suitable habitats for P. cf. bedriagae in southern Russia began to decline, but local habitats for P. ridibundus become more suitable. Therefore, a mosaic of populations consisting of these both species and their hybrids has now been found here. | |

| Аннотация: | Ground squirrels are ecosystem engineers and keystone species in many open landscapes of Eurasia, America, and Africa. They are model objects for population studies, behavioural ecology, life-history theory, and conservation biology, the research areas where microsatellite analysis is widely applied and fruitful. So far, microsatellite markers have been developed for only few Palearctic ground squirrels. We tested and characterized 14 markers previously developed for ground squirrels and 10 new loci with tri-, tetra-, and five-nucleotide repeats in the yellow ground squirrel, Spermophilus fulvus, a species widely distributed in Eurasia and endangered in some regions. We found polymorphism in 10 loci, five of them were highly polymorphic (5–14 alleles). These markers will benefit studies of the population genetic structure, parentage, mating system, reproductive success, and interspecific hybridization as well as conservation efforts in S. fulvus and other close-related Eurasian ground squirrels. | |

| Аннотация: | Testate amoebae are important components of benthic communities in freshwater lakes, where they play an essential role in decomposer food webs. They are used widely in paleoecological investigations because of their high taxonomic diversity, well-defined ecological preferences and decay-resistant tests. Studies of testate amoeba assemblages in lake surface sediments are necessary to better understand lake ecosystem function and improve the use of these organisms as bio-indicators in paleoecology. This study explored the use of testate amoebae as proxies for inferring past water level in freshwater lakes, and expanded upon the limited body of research into lake testate amoebae in Russia. Our results indicate that species composition of testate amoeba assemblages in the lakes was typical for such biotopes, with most of the species belonging to the genera Difflugia, Centropyxis, Arcella and Euglypha. Analysis of variation of testate amoebae along a water-depth gradient showed that three assemblage types could be distinguished: shallow-water (0–4.5 m), intermediate-water-depth (4.5–20.5) and deep-water (20.5–33 m). Deep-water assemblages did not contain any unique taxa and were dominated by eurybiotic and planktonic species. Species diversity was highest in the intermediate-water-depth assemblages and lowest in deep-water ones. Although variations in testate amoeba assemblages across water depth in freshwater lakes are complex and context-dependent, there are clear patterns in species composition and diversity, which can be used to infer past lake water levels. Future studies on the effect of water depth on testate amoeba assemblages in diverse types of freshwater lakes should increase the utility of the method. | |
