Ground beetles (Carabidae) on quarry terraces in the vicinity of Brno (Czech Republic)

Abstract

The occurrence of ground beetles (Carabidae, Coleoptera) was monitored in the exhausted limestone quarry of massif Hády near Brno using formaldehyde pitfall traps with a monthly interval of collection. Research was conducted from April to October in 2009 and 2010. The obtained material was investigated on some synecological characteristics and species affiliation to bioindication groups. In total for both years, 462 specimens of 43 species were captured. Most species were found in habitats with vegetation cover in the immediate vicinity of cultivated agricultural land – 441 specimens of 39 species. In the quarry itself only a minimal amount of ground beetles was found – 21 specimens of 11 species. Decrease in the abundance of ground beetles towards the center of the quarry was demonstrated. Next, significant species of Brachinus crepitans, Brachinus explodens and Cicindela sylvicola (endangered species pursuant to Decree 395/1992 Coll.) and species listed in the Red List were reported – near threatened Ophonus sabulicola and vulnerable Cylindera germanica (also endangered species pursuant to Decree 395/1992 Coll).
