Abstract


The classification of spring macrozoobenthos communities is carried out on original data. The 11 types of communities are shown. The differentiation factors of these communities are substrate type, water flow, water velocity. The two strategies of topical space division by communities are revealed. The first is when community occupies all existing biotopes. The second is when different types of the communities combine in the single spring. The former strategy realize by two modes: by the tolerance of predominant taxa and by the alteration in the predominant complex. Some types of community can show the both strategies in different hydrological conditions.

Key words


spring macrozoobenthos, types of communities, combination of communities
