Abstract
The patterns of changes in the species richness, abundance, species composition, and species structure of the testate amoebae community along six different types of water-land boundaries in the Medveditsa River (Don river Basin) were studied, namely, a new boundary, terrigenous and reogeneous edges, reogeneous and terrigenous hemiecotones, and the full ecotone. The testate amoebae communities are divided into terrestrial and aquatic variants for all types of boundaries. Hydrophilic species of the genera Arcella, Diffugia, Cyphoderia, and Pseudodifflugia dominate in the aquatic types of communities while pedobiont and eurybiont groups from the genera Centropyxis, Euglypha, Plagiopyxis, and Trinema are characteristic of the terrestrial communities. A decrease in the abundance and species richness of testate amoebae in the boundary zones was detected.
