Communities of epigeic beetles in the plantations of fast growing plant species for energetic purposes and in surrounding biotopes
 JAHNOVÁ, Zuzana
The aim of the work was to study the communities of epigeic beetles in plantations of energetic plants (Dactylis glomerata, Arrhenatherum elatius, Phalaris arundinacea, Helianthus tuberosus) and in surrounding lawn biotope. The method of pitfall trapping was used for beetle sampling from 2008 to 2010 during the growing season. Carabid beetles (Carabidae) and rove beetles (Staphylinidae) were used as bioindicators. In total 69 species and 1789 individuals were captured and evaluated. Eurytopic species were more common than stenotopic in all habitats, also the value of the index of beetle communities was low in all plots. RDA analysis proved the influence of surrounding biotope on beetle communities. It was concluded that communities of epigeic beetles might be also affected by the climatic factors, long termed population fluctuations of individual species, edge effect and microclimate inside the vegetation.
