Changing Asian mountain steppes require better conservation for endangered Argali sheep

We present a rare insight into the biodiversity of a remote, mountainous area of central Asia and outline challenges to conserve the critically endangered keystone argali (Ovis ammon ammon L.), the largest subspecies of mountain sheep. Existing conservation is set in the context of competition with livestock grazing and disturbance by local pastoralists. We suggest how this pressure would increase as pastures become degraded by a future more arid climate. Focusing on the transboundary population, migrating between the Russian and Mongolian Altai over the Sailugem Ridge, we track historical population numbers. Due to increased protection, the argali’s local population is currently growing. However, most argali populations live outside the protected areas where they are forced to compete for forage with livestock. Due to ever-increasing anthropogenic pressures, argali has almost reached the region’s environmental capacity, so the number of local populations is decreasing. Consequently, even the current situation requires more areas of protection, and climate change will accelerate pasture degradation, thereby further increasing competition with livestock. We present various ways to predict the impacts of changes in climate, e.g., the “7 M’s approach” and grazing pressure and then recommend additional conservation measures acceptable for the indigenous population of traditional pastoralists

Paleolithic Man of Denisova Cave and Zoogeography of Pleistocene Mammals of Northwestern Altai

Mammal population of the northwestern Altai included residents, autochthonous species, cosmopolitans, and migrants. The last clearly indicate biogeographical relationships of the biota of the Altai Mountains in the Pleistocene. Most of them penetrated into the Altai from the south. The majority of ungulates and rodents migrated from Central Asia. Yak, red dog, and snow leopard came from the Himalayas, Pamir, and Tien Shan. The natural environment of the Altai Mountains in the Pleistocene enabled migrations of these mammals from the south to north. The same opportunity was true of the ancient man. It is possible to assume that humans migrated from southeastern Asia and Indochina along the eastern foothills of the Himalayas and Nan Shan Mountains to the northwest, to the Zaisan Depression and Altai. This resulted in inevitable exchange of gene material of Paleolithic human populations of southeastern Asia and the Altai
