Abstract: | The species composition and structure of plant communities related to the activity of Formica rufa ants were studied in green moss pine forests located in Nerusso-Desnyanskoe Polesye (Bryansk Province). Four types of microsites
were established and examined: (1) the mound of an active ant nest, (2) the soil bank around an active ant nest, (3) the mound
of an abandoned nest, and (4) the soil bank around an abandoned nest. The background plant community was considered as the
fifth type. According to MRPP method, all pairs of microsites except (3–4) were different both in plant species composition
and species abundance. The microsites created by Formica rufa increase the habitat capacity and β diversity of the plant communities due to the appearance of meadow species requiring
richer soils. |
