Long-term dynamics of the species composition of herpetobiont and hortobiont beetles (Coleoptera) in the Galichya Gora Nature Reserve

Аннотация

A long-term study of the species composition of adult beetles (Coleoptera) was performed in the Morozova Gora locality (the Galichya Gora Nature Reserve, Lipetsk Province, Russia). From 1995 to 2005, a total of 23 683 ind. of 545 species from 57 families were captured in the migration trap, i.e., a system of 10 pitfall traps connected by guide barriers. Net-sweeping of the herbage in the steppe, oak grove, and meadow yielded 9048 ind. of 383 species from 33 families. The species composition of herpetobiont beetles was shown to change gradually in time, while that of inhabitants of the herbage layer changed sharply from year to year. The abundance dynamics patterns varied greatly between species and habitats.
