Patterns of formation of island Rhopalocera fauna at the northern forest boundary in the region of Valdai inland ice were analyzed by the example of White Sea islands. The ecotone effect, typical for northernmost taiga and forest-tundra and introducing the transitional Rhopalocera fauna in near-tundra forest between the boreal and hypoarctic zones, was not observed on the White Sea islands. Island isolation provided for the absence of some Arctic species, entering near-tundra forest from the North, in the island fauna. Island Rhopalocera faunas represent poor variants of the northern taiga fauna lacking some polyzonal and temperate species and having a reduced set of Arctic boreal species. |
