[Dynamics of the helminth fauna in the common shrew (Sorex araneus L.) from cut-over lands of different age in Karelia].

Abstract

Species diversity of helminths in the common shrew from three cut-over lands of different age in Karelia was studied. It was shown, that change of the plant cover in cut-over lands have no a significant effect on the species diversity of helminth communities in Sorex araneus, but the abundance of individual parasite species changes considerably. Changes of the S. araneus infestation with helminths were the greatest in a new cut-over land. Structure of the helminth community comprises four categories of parasites (dominants--4 species, subdominants--8, rare species--13, very rare species--10) and depends on the time passed since the felling. A redistribution of the species constituting the core of the helminth fauna was to be observed. It was shown, that being an integrated indicator of the status of terrestrial ecosystems, parasites clearly indicate changes not in the structure, but in the abundance and domination of individual species of terrestrial invertebrates and vertebrates in cut-over lands.
