Spring distribution of beetles (Coleoptera: Carabidae) in abandoned agroecosystems and surrounding forests

In most habitats in temperate zones, Carabidae show clear intra-annual changes abundance and species composition. the spring, we studied beetle fauna 5 different biotopes differing degree of overgrowth birch forest over a period three years. According to years research, 10,528 specimens (64 from 6 subfamilies) were collected. Twelve beetles found all biotopes. The highest numbers obtained 12-15-year forest; lowest abandoned lands. biodiversity was ecotone at border young fallow A high Shannon Biodiversity Index low Simpson indicate that communities lands are equalized.
