Проблемы изменчивости синтаксонов в Арктике
Variability or variation of syntaxons of Arctic is seen as a change in their floristic composition, biomorphic set and structure types when the geographic location and environmental conditions are change.

Variability or variation of syntaxons of Arctic is seen as a change in their floristic composition, biomorphic set and structure types when the geographic location and environmental conditions are change.

Examples of local, regional and major associations are considered. The formation of a geographical association is determined by two groups of factors: the process of phylogenesis and major changes in the physio-geographical environment occurring in the geological past.
