It was studied bumblebee communities in the European North of Russia (Eastern Fennoscandia, the taiga zone of north Russian Plain, Eastern European tundra). The aim of this work was the study of bumblebee communities in different types of ecosystems of European North and investigates them in the context of changes of species distribution in northern Europe. The most abundant species in the study region are usually Bombus cryptarum and B. jonellus. Some species of bumblebees (B. distinguendus, B. veteranus and others) are considered as southern immigrants in northern Europe. They will colonise the northern parts of European Russia in the middle and late 21st Century, according the models of future species distribution. These southern species are common in anthropogenic habitats. Unlike ruderal habitats, bumblebee assemblages of undisturbed ecosystems in the European North have not any southern species as B. distinguendus and B. veteranus, and are characterised by higher abundance of tundra species (B. lapponicus, B. polaris and others). Assemblages of ruderal habitats consist, mainly, of ubiquitous and boreal species and a number of southern immigrants. The general pattern is that bumblebee assemblages of anthropogenic habitats in northern Europe are enriched by southern immigrants, which are absent in native taiga and tundra ecosystems. This study was funded by RFBR, according to the research project № 16-34-60035 mol_а_dk.
