Abstract
The occurrence of density compensation effect (DCE) was estimated in areas of extreme habitats occupied by communities of vascular plants, mosses and lichens in the high mountain part of the North Caucasus. The density of species was estimated according to their frequency. The nature of the correlation between number and frequency of the species in the areas did not confirm the suggestion that extreme environmental conditions alone can be a reason for DCE, at least on local scale.
