“…Tissue DNA isolation was successful in only eleven mussels (five from Chukcha Lake and two samples from each of the other three populations). DNA was isolated from soft tissue samples fixed with ethanol using BioSilica columns (Novosibirsk, Russia) according to a published protocol [27]. A fragment of the cox1 mitochondrial gene was amplified with the universal primers LCOm and HCO [28] within project no.…”

The origin of the fauna of Beringia is a notable biogeographical puzzle. Large mussels of the genus Beringiana inhabit both Northeast Asia and the northwestern part of North America and thus provide an important model to investigate the paleobiogeography of Beringia and the past and current intercontinental species exchanges. Data on Beringiana distribution, morphology, genetics, and taxonomy are fragmentary or questionable. In this study, we summarized the data on its distribution in Northeast Asia, performed genetic analysis (cox1), and studied the variation in the shell morphology in samples from four isolated populations, including the putative sympatric species. Over ten large enclaves of Beringiana are currently known in Northeast Asia (east to the Verkhoyansk Range), mostly in the lower reaches of large rivers in northeastern Yakutia, Kamchatka, Magadan Oblast, and Khabarovsk Krai. These enclaves are far apart (several hundreds of kilometers) because the mussel is associated with muddy sand or pebbly sand bottom substrates and spreads through its glochidia, which are parasitic on the fish. Shell morphology can be highly variable even in a single population, overlapping the diagnoses of several Beringiana species (which are currently not recognized as valid). Our analysis of the cox1 sequence in four populations identified all individuals as B. beringiana. We evaluated the possible current and probable Late Pleistocene–Early Holocene freshwater and marine pathways of B. beringiana dispersal through the area of former Beringia, including the current intercontinental migration of glochidia on fish.

“…A. rosea значно розширив свій ареал за останні два десятиліття і тепер зустрічається в Західному Сибіру. Порівняно з близькоспорідненим видом A. caliginosa, A. rosea має більш низьке генетичне різноманіття, що, ймовірно, викликано меншою кількістю випадків розселення (Shekhovtsov et al, 2020). Дощовий черв'як A. rosea часто зустрічається в розріджених популяціях, де виживання можливе здебільшого за рахунок партеногенезу (Vlasenko et al, 2011;Mezhgerin et al, 2018).…”

An ecomorph reveals the relationship between organisms and the environment and reflects the level of their adaptation to the most important elements of the biogeocenosis. The eco-morphic approach to the analysis of ecological systems is a component of the concept of ecomorphic matrices. The ecomorphic matrices consist of blocks comprising the synecological properties of the soil animal community, each reflecting a particular aspect of its ecological features. The systemic combination of these characteristics is able to provide a comprehensive reflection of the diversity and functional state of the community. As a result of research on the territory of green areas in the city of Dnieper and Melitopol revealed 53 species or taxon species level representatives of soil macrofauna of the 48 genera and 32 families, 13 orders, 7 classes and 3 types. The article presents the biological and ecological characteristics of macrofauna species. Analysis of the ecomorphic structure of communities of soil macrofauna showed that in the cenomorphic structure prevail syl-vants, which represent 44.2% of the species richness of the community. Differences between com-munities Melitopol and Dnieper on cenomorphic structure statistically not reliable. Saprophages and predators prevail in trophic structure of soil macrofauna communities. Topomorphic structure of communities is dominated by epigeic forms (65.4%) and considerably exceeded by endogean forms (32.7%) Only one species represents burrowing soil animals – D. nassonovi. The community is dominated by mesophiles, which is typical for forest cenoses. Megatrophocenomorphs predomi-nate in the trophocenomorphic structure of the community. Aerophiles (48.1%) and subaerophiles (34.6%) predominate in the communities. The dominance of aeromorphs sensitive to the provision of air for breathing, indicates a satisfactory air regime in the soil green areas of public use. Carbon-atophiles are most represented in the community. Communities of soil macrofauna of public green spaces has features of amphicenosis, in which steppe and meadow components are significantly represented against the background of predominance of forest component. Tree plantations in a city park form a common forest environment, although they do not form a stable forest monocenosis. Recreation and other forms of anthropogenic influence do not allow the formation of a forest mono-cenosis or pseudomonocenosis. The trophic aspect of the structure deciphers the importance in the community of the cenotic components. The trophic structure of sylvants repeats the trophic structure of the community as a whole and this allows us to consider sylvants as the functional basis of the soil fauna community. Phytophages prevail among sylvanians, which fully corresponds to typical trophic structure of steppe zonal communities. This peculiarity taking into account proportional representation of zoophages and saprophages allows to estimate as functionally stable structure of the steppe community.
