Landscape chorology of collembola on Taimyr Peninsula. 2. Biotopic preferences of species [Russian]

摘要

The distribution of collembolan species was analyzed on a transect from the northern taiga up to the polar deserts in Central Siberia. Groups of species similar in the latitudinal distribution were distinguished in Taimyr tundras. The share of natural Arctic species mainly related to the Subarctic treeless landscapes is rather high (more than 45% of the regional species list). This is unusual for such a primitive group. The pattern of the latitudinal distribution of Collembola on Taimyr differs little from that common for other taxa of terrestrial animals. All specific features of the zonal distribution of species described in the literature may be illustrated through the example of Collembola.
