Brouci (Insecta: Coleoptera) sutí vrchu Plešivec (severní Čechy, CHKO České středohoří)

Abstrakt: Thirty one beetle species (Coleoptera) were found in the rock debris of the Plešivec hill (České středohoří Protected Landscape Area, northern Bohemia), in 1993. Modified pitfail traps baited with fish meat and ripened cheese, located near the debris surface were used. The relict cold-adapted species Pterostichus negligens (Sturm, 1824) (Carabidae) was present only in ice hollows at the base of the western slope; the psychrophilic small carrion beetle Choleva nivalis (Kraatz, 1856) (Leiodidae: Cholevinae) was found at the same place and also on the northeastern slope. Thermo- and xerophilic species were found at warm top part: Nargus wilkini (Spence, 1815) (Leiodidae: Cholevinae), Trox scaber (Linneaus, 1767) (Trogidae), Dermestes undulatus Brahm, 1790, D. murinus Linneaus, 1758 (both Dermestidae) and Ptinus schlerethi Reitter, 1884 (Ptinidae). Using the coefficient of Sorensen and UPGMA, cluster analysis of traps’ similarity is provided.
