“…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). Для виду характер-не високе різноманіття клонів.…”

“…Навіть у межах однієї популяції обов'язково існує декілька клонів, а клони з різних популяцій не бувають ідентичними. Такий високий рівень генетичного різноманіття виду обумовлений високою мутабельністю геному (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.

“…A distinctive feature of the evolution of their karyotypes is polyploidy, which is widespread in the family. The polyploid races and subspecies occur as frequently as the diploid ones (Bulatova et al 1987, Perel 1987, Viktorov 1993, 1997, Kashmenskaya and Polyakov 2008, Garbar et al 2009, Vlasenko et al 2011). Di- and polyploid forms tend to be spatially isolated, with the latter occurring predominantly at the edges of the species’ ranges (Grebelnyi 2008, Kotsyuba et al 2010, Onyschuk and Garbar 2010).…”

Sixty-six specimens of the earthworm Drawida ghilarovi Gates, 1969 (Oligochaeta, Moniligastridae) from 15 localities of the southern Russian Far East were studied cytogenetically. We examined chromosome sets during mitosis and diakinesis as well as DNA content in the spermatogenous and somatic cell nuclei. The populations and morphs displayed no differences in karyotype and ploidy levels estimated in terms of both chromosome number and DNA mass index: n = 10, 2n = 20; c = 1.1 pg, 2c = 2.2 pg. We conclude that polyploidy as a species- or race-forming factor is not typical of these earthworms.
