Abstract | Lake Baikal, the largest freshwater lake in the world and UNESCO world heritage site, is inhabited by an exceptionally species-rich, largely endemic fauna which is distinct from faunas from other freshwaters in the Palearctic. With regard to species-richness, extremely high abundance of individuals and high total biomass amphipods (Amphipoda, Crustacea) constitute a major, ecologically highly relevant animal taxon of Lake Baikal. The “immiscibility barrier” of faunas, i.e., the separation of amphipod faunas from Lake Baikal and other Palearctic waters, is believed to be related with the high degree of adaptation of Lake Baikal species to the specific environmental conditions of their habitats; under these conditions they outcompete potentially invasive non-Baikal species that are unable to establish stable populations in Lake Baikal. It is a question of great interest whether the current global change related, massive alterations of temperature and chemical conditions in Lake Baikal will favor potential invasive species. Our molecular and physiological studies with representative endemic Eulimnogammarus species show that these species are indeed equipped to deal with stress from unfavorable environmental conditions and in comparison to a potentially invasive amphipod may not necessarily be more sensitive. However, considerable differences in stress responses among the different species suggest that species shifts in the Lake Baikal ecosystem may occur when environmental conditions continue to change. |
