The distribution of the often dominant in density and biomass epi-endogeic and endogeic earthworm species in forests of the Northwest Caucasus was estimated based on a large array of field data and GIS modeling of modern potential areas. Quantitative accountings of earthworms were conducted annually from 2014 to 2019 in different types of forests: sticky alder forest, small-leaved forests, broadleaf forests (hornbeam and beech forests), coniferous-deciduous forests, dark coniferous forests, and pine forests (792 geographic locations). It is shown that the native species of the Caucasian fauna dominate in the number and biomass from piedmont to high mountain forests.

Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, and soil properties.

- - The study focuses on an autochthonous Siberian earthworm species known for its wide distribution across various ecosystems and high levels of diversity, prompting the idea of splitting it into multiple species.
- - Researchers used genetic analysis, including COI gene diversity and transcriptome sequencing, to investigate the species' phylogeny, finding it to be monophyletic but divided into two distinct clades based on geographical distribution.
- - The authors propose to classify the species into two separate species based on these findings, abolishing the current recognition of a non-pigmented subspecies and expanding another to include previously identified lineages.
