Earthworm Populations (Oligochaeta, Lumbricidae) in the Basin of the Middle Reaches of the Bol’shaya Laba River (Northwestern Caucasus, Buffer Zone of Caucasian Nature Reserve)
Journal: Biology Bulletin
Year: 2019

The species composition and structure of the population of earthworms in the forest and meadow formations in the basin of the middle reaches of the Bol’shaya Laba River are studied for the first time. The species of the Crimea and Caucasus are unusually rare. The erosion topography in combination with significant precipitation results in increased heterogeneity of habitats and in the formation of specific taxocenoses with respect to a hydromorphic or automorphic soil regime. The Crimean–Caucasia
