Zonation in the plant cover on the Wrangel Island: syntaxonomical approach

Research on Wrangel Island reveals distinct vegetation zones characterized by unique syntaxonomic traits. The study identifies four variants: two arctic tundra subzones (southern and northern), a northern typical tundra subzone, and a southern coastal polar desert zone. The polar desert zone exhibits the lowest diversity, with minimal syntaxa presence, reduced vascular plant cover, and increased lichen dominance. In contrast, the northern typical tundra shows high diversity, including 19 syntaxa on south-facing slopes and the highest phytomass (89.9 g/m²). Arctic tundra variants share similar diversity metrics but differ from other zones in syntaxa distribution and species composition. The study employs hierarchical subdivision using syntaxonomic criteria, including zonation indexes, species-area relationships, and typomorphic groups, providing a nuanced understanding of Wrangel Island's vegetation dynamics.
