Arealogical characteristics of the bee fauna (Hymenoptera: Apoidea: Apiformes) at Zeysky nature reserve (Amur region)

Arealogical characteristics of the Apoidea superfamily (section Apiformes - bees) fauna at Zeya Nature Reserve is presented by the author, based on the works by K.B. Gorodkov. We have analyzed the ranges of 134 native species from 6 families and 25 genera, currently collected in the southeastern part of the Tukuringra Ridge within the Reserve and its protected zone. Species are distributed into 20 types of ranges (chorological groups). Nine groups were distinguished by longitudinal component: Cosmopolitan (2 species - 1,5%), Circumholarctic (9 species - 6,7%), Amphigolarctic (6 - 4,5%), Transpalaearctic (50 - 37,3%), Eurasian (3 - 2,2%), Amphipalaearctic (22 - 16,3%), East Palearctic (11 - 8,3%), Siberian-Dalearctic (8 - 5,9%), Far Eastern (23 - 17,2%). By latitudinal component four groups were identified: boreal (6 species - 5,2%), subboreal (26 - 19,3%), temperate (18 - 13,5%), polyzonal (83 - 61,8%) - the most multispecies. There are no endemics inside the study area. Historically, the fauna has had an integral character, without any anthropogenic influence. The Zeya River, which borders the Reserve and flows in the south direction, has a great influence on biological diversity in general. The territory is characterized by a sharply continental climate.
