The role of different hedgerow types in shaping carabid beetle assemblages (Coleoptera:Carabidae) in agricultural landscape
 JAHNOVÁ, Zuzana
Detailed record
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.

Communities of epigeic beetles in the plantations of fast growing plant species for energetic purposes
 JAHNOVÁ, Zuzana
The aim of the work was to study the communities of epigeic beetles in plantations of fast growing plant species for energetic purposes. The method of pitfall trapping was used for beetle sampling. Four plots of fast growing plants were studied {--} Dactylis glomerata, Arrhenatherum elatius, Phalaris arundinacea and Helianthus tuberosus. Carabid beetles (Carabidae) and rove beetles (Staphylinidae) were used as bioindicators. It was found 18 species and 45 individuals of family Staphylinidae and 25 species and 594 individuals of family Carabidae (43 species nad 639 individuals in total). The highest number of species was found on plot of Dactylis glomerata (28 species) and the highest number of individuals was found on plot of Phalaris arundinacea (246 individuals). The majority of the beetles were carabid beetles belonging to the next species - Poecilus cupreus, Pseudophonus rufipes, Calathus fuscipes, Harpalus aeneus and Nebria brevicollis. These species occured in all plantations. Eurytopic species were more common than stenotopic in all habitats. The smallest value of index of human impact and so the biggest human impact was found in reed canary-grass. It is supposed that the communities were influenced by the surrounding biotope (lawn) and the weather during the period of experiment.
