ИСТИНА

The presentation shows specific examples of the current dynamics of the Arctic biota, due to biotic significant climate changes or other factors that are important for understanding modern processes in the ecosystems of the Russian Arctic. The formation paths of current habitats of Arctic mammals are traced and a forecast of their changes is given with further climate warming, features of the population dynamics in recent decades for model species of lemmings, reindeer, waterfowl and seafowl birds are revealed. It is shown that not all changes in the Arctic biota can be explained by climate changes. The analysis is supplemented with materials assessing the current dynamics of the Arctic flora and vegetation. A mechanism of the Arctic “greening” is shown in terms of the assessment using remote sensing and field methods.
