- Аннотация: Biotopic preferences of species can be useful for community characterization. Communities of soil micrarthropod Collembola consist of four categories of species: specialized to the natural biotope being examined, specialized to a different natural biotope, eurytopic and disturbed site species. Four categories of communities (specialized, eurytopic, modular, and ruderal communities) can be distinguished according to the dominance of different biotopic groups. Spectra of biotopic groups are found to be sensitive to human activities. The ratio between specialized and eurytopic species decreases both under industrial pollution and the degree of urbanization. A high diversity (due to high evenness) of biotopic groups is characteristic of modular collembolan communities in urban soils. Specialized collembolan communities are consequently replaced by eurytopic, modular and ruderal ones along gradients of human impact.
