Conjugate occurrence of species in the community of the mountain-tundra belt in Khibiny Mountains (Murmansk Region)

Abstract

Strongly mosaic community rich in species was located in the mountain-tundra belt of the Khibiny Mts. The species of the community form two groups of species related to each other by positive correlations. There are six species in common for two groups. In the smaller group there are almost no negative correlations, in the larger one there is a division into subgroups with a large number of negative correlations between subgroups. Plants with a dwarf -shrub life form often avoid each other.
