Abstract
The article is based on the original data obtained during the study of soil gamasid mites (Mesostigmata) in 24 typical habitats along an altitudinal gradient at 400–1860 m a.s.l. in physico-geographic province of North Altai. The changes of main sinecological characteristics — taxonomic richness, total abundance and index of b-diversity of populations — were discussed. Analysis of the distribution of species with different types of habitats along the altitudinal gradient with regard to their number and abundance was carried out. The spatial-typological structure of soil gamasid mites populations in North Altai was characterized as inhomogeneous, and the impact of the main environmental factors on it was evaluated.
