Biocentra a biokoridory v zemědělské krajině - význam pro společenstva epigeických brouků (Coleoptera) / Biocentres and biocorridors in agricultural landscape - importance for communities of epigeic beetles (\kur{Coleoptera})

STLUKA, Pavel January 2013 (has links)
Communities of epigeic beetles were monitored on five localities, which were found in South Bohemia in Písecku. There were places located in agriculture landscape, which is affected by human activities. Selected localities were composed of biocenters and biocorridors. There were forest localities (spruce monoculture, age 60-70 years), edge of the forest, corn field and two groves with different sizes. The method of pitfall trapping was used for sampling. There were found 2409 specimens of epigeic beetles (15 families and 70 species). The highest number of epigeic beetles was found on both groves. There were found 864 individuals in smaller grove and 684 individuals of beetles in larger grove. Activity of beetles in the other localities was lesser. There were found 403 individuals on field, 333 individuals in the edge of forest and least number of beetles (125 individuals) was found in forest. Species´ spectrum of epigeic beetles was divided into three groups according by the sensitivity to antropogenic impacts (relict, adaptable and eurytop species). There were found only two last groups according by the sensitivity to antropogenic impacts of three (relict undetected). There were 51 eurytop species (E) and 19 adaptable species (R2). Counted index of antropogenic influence on communities of epigeic beetles proceeds in low values (communities are relatively strongly influenced by human). Forest habitat was affected least and corn field habitat was affected most. Groves are very strongly influenced by human too, but its values are better than values on field. Groves thus have a positive impact on communities of epigeic beetles and it can be compared with the edge of forest.
