136 bones of the postcranial skeleton and a part of the skull of a female Baikal yak (Poephagus mutus baikalensis N. Verestcthagin, 1954), originating from 18 cave locations and open-type Paleolithic sites in Altai-Sayan, Transbaikalia and Central Mongolia were examined. The material includes 38 metacarpals and 9 metatarsals of the yak. Morphometric differences in the structure of the postcranial skeleton of the yak and the bison (Bison priscus Bojanus, 1827) were revealed. The body size of the Baikal yak significantly exceeded that of the wild Tibetan yak (Poephagus mutus Przewalski, 1883). The largest representatives of P. m. baikalensis inhabited the Altai Mountains. In most of the sites, located in the mid-mountain landscapes of Southern Siberia (with absolute heights of 500–700 m), only a few remains of the Baikal yak were found, accounting for 0.01% to 1–2% of the number of megafauna remains. Most likely, herds of yaks did not live here permanently, but appeared only sporadically, during seasonal migrations. In higher mountainous areas (from 1000–1500 m) of Gorny Altai and Khangai Mountains in Central Mongolia, the proportion of the remains of the Baikal yak increases significantly – up to 16–22%. Like the contemporary P. mutus, the Pleistocene yak found its ecological optimum in the high-mountainous parts of ridges and mountain plateaus, dominated by cold, dry mountain-steppe landscapes with herb-grass vegetation and a small amount of snow. During the periods of cryochrones, the area of P. m. baikalensis apparently expanded significantly, incorporating the adjacent foothill territories. During the periods of thermochrones, it was most likely limited to the high-mountainous areas of the mountain uplifts of Southern Siberia.

The Impact

The growing interest in mountainous areas is accompanied by the expansion of the process of involving unique landscapes in economic circulation, which often leads to a disruption of the natural balance. Consequently, the need for a change in the inertial paradigm, reorientation of the development of society to the path of constructing a sustainable system of environmental management is becoming more acute. This idea can be realized through the creation of ecological and economic zones, which imply the implementation of the concept of landscape organization and proportionality on the basis of the conservation and functionality of mountain landscapes. Background. The main purpose of the article is to actualize the urgent need to find a compromise between the market aspirations of various categories of nature users and the system of protected areas in the mountainous zone of the Kabardino-Balkarian Republic (KBR). To achieve this goal, the following tasks were solved: identification of the peculiarities of mountain valley landscapes in relation to the concepts of "threshold" and "capacity"; analysis of the possibilities of ecological optimization of the use of functional landscapes; Евразийский Союз Ученых (ЕСУ) # 12(81), 2020                                                                  5 search for a compromise option for co-development of the main types of landscapes that are of practical importance. Methods. In accordance with the intended goal and tasks, the authors relied on the following research methods: using the cartographic method, the centers of the impact of large hazardous natural processes on functional landscapes were considered and their paragenetic connections with adjacent fragments of geosystems were analyzed; the route method made it possible to trace the indicative connections between disturbed geo-complexes and anthropogenic pressure on the mountain-valley complexes Bashil - Chegem section of the high-mountain reserve; based on the predictive method, it is recommended to impose an additional tourist and recreational function on mountain-meadow landscapes; on the basis of an experimental method, the achievement of a critical level of sparseness and death of ageold pines within the forest park landscapes of the Elbrus region was confirmed. This publication is based on theoretical and empirical studies of Russian and foreign scientists: Isachenko A.G., Kochurova B.I., Beruchashvili N.L., supplemented by the specification of the territory under consideration.

Recent Project

Mountain glaciers represent an important hydrological and touristic resource, and their recent evolution provides a dramatic evidence of climate change for the general public. Glacier inventories, quantifying glacier characteristics and evolution, are an important tool to describe and manage high mountain glacier environments and Italy has developed a long tradition in this sector. Our country was the first to provide itself with a glacier inventory, compiled by Comitato Glaciologico Italiano and CNR, showing a glacier surface of 530 km2. A recent project, coordinated by Università Statale di Milano with the support of private bodies and the cooperation of Comitato EvK2CNR and Comitato Glaciologico Italiano, led to the development of the new Italian Glacier Inventory, a national atlas produced from the analysis of color orthophotos at high resolution acquired between 2005 and 2011. The New Italian Glacier Inventory lists 903 glaciers, covering an area of 370 km2. The largest part of glacier area is located in Val d’Aosta (36.15% of the total), followed by Lombardia and South Tyrol. 84% of glaciers (considering the number of glaciers) have an area lower than 0.5 km2 and jointly account for 21% of the total glacier surface. Glaciers larger than 1 Km2 make up 9.4% of the total number, but cover 67.8% of the total glacier area. The comparison between data from the New Italian Glacier Inventory and the CGI-CNR inventory (1959-1962) shows a 30% reduction in glacier area in Italy; considering instead the World Glacier Inventory or WGI, published at the end of the ‘80s, which reported 1381 glaciers and an area of 609 km2, glacier loss sums up to 478 glaciers and an area of 239 km2 (-39%). This shrinkage has led to rapid and significant changes to high mountain landscapes, notably glacier fragmentation, an increase in deglaciated areas, the formation of proglacial lakes and the development of pioneer vegetation.

A high-resolution paleoclimatic record for the last two glacial – interglacial cycles has been documented at Kurtak in southern Siberia. A unique, 34 m high late Quaternary loess section (section 29) with a series of 32 variably developed paleosol horizons provides evidence of a strongly fluctuating, but patterned, climatic change. Mineralogical composition and grain morphology of the undifferentiated (aeolian and colluviated) loess indicate a local provenance and a short transport of the silt, derived by glacial erosion of the granitic and metamorphic bedrock in the Kuznetskiy Alatau and eastern Sayan mountains, and subsequently subaerially redeposited from the alluvial plain in the Yenisey River valley. The succession of Chernozemic, Brunisolic, and Gleyed Regosolic soils, alternating with nonweathered or weakly weathered loess events, matched by parallel changes in magnetic susceptibility, can be correlated with marine isotope stages 1 – 7. The magnetic susceptibility pattern is completely opposite to that of the Chinese loess record, where magnetic susceptibility is highest in paleosols, as opposed to lowest in Kurtak paleosols. The reason for this is not completely understood. Nevertheless, the magnetic susceptibility profile correlates well with the last two glacial – interglacial cycles. Furthermore, isotope stage 5 includes several short-duration, relatively small amplitude susceptibility signals corresponding to equivalent signals in the δ18O record. These include the colder intervals (stadials?) 5b and 5d, warmer intervals (interstadials?) 5a and 5c, and the "optimum" warm interval 5e.
