An Actual Biogeographical Hazard of the Expansion of Small Mammals and Their Parasites Linked with Climate Changes in the East Nepal Himalaya

The results of zoological and parasitological research in the MakaluMakalu-Makalu Barun area, Makalu base camp Barun region are presented. These findings are compared with the landform evolution during the Quaternary. The complex interpretation made it possible to determine the expansion and migration of small terrestrial mammals in correlation with the orogenetic uplift and changes in the extent of mountain glaciation since the Upper Pleistocene. Biogeographical hazards and risks associated with the rapid expansion of the periglacial climate-morphogenetic zone and the increased human impact in the High HimalayaHigh Himalaya are emphasized.
