Changing of beetles (Insecta: Coleoptera) population structure of pine fireplaces with the age of burnt site

The paper deals with the species and trophic structure of beetles population, living in different aged fireplaces and lichen pine stands. The researches were carried out in June-August of 2005-2007 years. Five fireplaces and two control pots were investigated. 130 species (103 genus, 31 families) were collected. 17 trophic groups were discovered. The species composition and quantity of beetles populating burnt sites depend on volume of forage basis. The trophic structure changes with succession.
