Carabid (col. Carabidae) aggregations in the production cycle of tree stand on fresh-soil mixed coniferous forest sites

摘要

The development of carabid aggregations in the fresh-soil coniferous and fresh-soil mixed coniferous forest sites was compared. The stands grew on forest and former agricutlural land. The representatives of forest fauna, big zoophages, autumn species were less abundant in carbid aggregations developing on the fresh-soil coniferous forest site, by about 20/100 than in respective aggregations from the fresh-soil mixed coniferous forest site. The average individual biomass was respectively by about 20/100 lesser too. Moreover final aggregations of carabids from the poorer variant of the fresh-soil coniferous forest did not reach the complete set of species recorded from the fresh-soil mixed coniferous forest site.
