Ecological arrangement of floro-faunistic heterogeneity of Northern Eurasia

In the previous articles on the faunistic and floristic zoning of the northern Eurasia the results were summed up. At first, in was done on all classes of terrestrial vertebrate animals separately, then on fishes and cyclostomes and after that on all these groups together (Ravkin, Bogomolova, Tsybulin, 2015a) as well as on invertebrate animals and flora of woody plants (Ravkin et. al., 2014, 2015b). The main aim of this analysis is a complex biotic zoning apart from comparing the variants of the local zoning produced on the same basis and using the same approaches and computing instruments.
