Abstract Based on the studies conducted in 2012-2020 on the key plots of mixed fir tree woodlands that grow within the Ulan-Burgasy Mountain range, the authors identified a special nemoral group of lepidopterans, that typically inhabit ocean coastline mixed and broad-leaved forests. Another peculiarity of this area is the presence of species atypical for the major part of the Transbaikal Region: Spialia orbifer Hbn., Leucodonta bicoloria Den. et Schiff., Furcula bifida Brahm (Sub-boreal group); Laothoe populi L. (Central Palearctic group); and Feralia sauberi Graes. (Palearchearctic group). The comparison of Lepidoptera faunas on the key plots and other forest and forest-steppe habitats in the Transbaikal Region revealed their high similarity (more than 80%) to the Ulan-Burgasy humid forests that grow near Baikal and mixed fir tree taiga forests of the Khamar-Daban Ridge.

AbstractThe increasing animosity towards wolves (Canislupus) by livestock-keeping nomads in Mongolia and the accompanying conflicts highlight the urgent need for knowledge about the feeding behavior of wolves, since information on the feeding ecology of wolves in Mongolia is rare, especially in the mountain taiga and mountain forest steppe regions of Northern Mongolia. Those regions are characterized by a relatively high wildlife diversity and are sparsely populated by humans. To face this problem, 137 wolf scats were collected in the Khentii Mountain range in Northern Mongolia between 2008 and 2012. Almost all wolf faeces contained remnants of wild ungulates, which made up 89% of the consumed biomass. Siberian roe deer (Capreoluspygargus) was the most important and positively selected prey species. It was followed by red deer (Cervuselaphus) and wild boar (Susscrofa), which was negatively selected by wolves. Wolves also fed on buffer prey species such as lagomorphs and small mammals. No evidence of domestic ungulates was found in the wolf diet. Thus, near-natural habitats with a diverse fauna of wild animals are important to limit livestock depredation.

Mountain Taiga

The Munku-Sardyk mountain range is an important link in the Eastern Sayan mountain system, performing a barrier and refugial role for various mammalian species, in the transition zone between the Central Asian steppe and the Siberian taiga. Thus, the southern steppe slopes are the northern limit in the distribution of the Tuvan and Mongolian voles, Tarbagan marmot, tolai hare, mountain weasel and manul. For the Altai mole, brown bear, sable, Siberian musk deer, reindeer and elk, the southern border of their distribution lies in the forest zone of the Khubsugul region. The paper presents the basic information about the features of the vertical distribution of mammals on the southern and northern slopes of the massif. The complex structure of the vertical zonation of the mountain range and the harsh habitat conditions are of paramount importance in the distribution and number of mammals inhabiting it. The species composition of communities in five high-altitude belts is presented: forest-steppe, mountain- taiga, subalpine, alpine and nival. A comparative analysis of the degree of similarity of mammalian communities, depending on the altitudinal zonality and exposure of the slope, using the Jaccard coefficient, based on the analysis of qualitative data, has been carried out. A high degree of similarity of the lower belt with the higher one was revealed on both slopes of the mountain range. The highest degree of similarity between the mountain-taiga and subalpine belts was noted, and the lowest degree was observed in the forest-steppe and nival belts that were separated from each other. The low species diversity in the nival belt is associated with the harsh habitat conditions associated with the absence of protective feeding stations and mechanisms of adaptation to hypoxia in most mammals living in the lower part. When comparing the community of mammalian faunas between the belts of the southern and northern slopes, a high similarity of mountain-taiga belts and a decrease in the proportion of common species with height were noted. The obtained information eliminates the existing gaps in the territory poorly studied in the zoogeographic plan and makes it possible to form a unified environmental policy in the transboundary region.

The Ulziit Mountain has a unique ecosystem which is one of northern branch mountains of Khangai mountain range in Mongolia. Several field survey were conducted in summer in all habitats in different altitudes. A total of 314 taxa were registered belonging to 161 genera from 52 families in Ulziit Mountain flora. The family Asteraceae was found to be the largest with 37 taxa, followed by Poaceae with 30 taxa, Ranunculaceae with 24 taxa, Cyperaceae, Caryophyllaceae and Rosaceae each with 17 taxa, Salicaceae with 16 taxa, and Fabaceae with 15 taxa; in total, these comprised 55.1% of all flora complements in this mountain. During the investigation, 5 species were newly recorded in the Khangai mountains forest-steppe region. The most represented life forms in the flora are hemicryptophytes (71.97%), which are common for mountain steppe vegetation. In a time of climate change, effective conservation of nature is needed at an ecosystem such as a single mountain particularly for endemic, relict and other salient species. Furthermore, such a detailed floristic survey is important for finding new records in the field of plant taxonomy and conservation of nature in these specific areas. Bangladesh J.

Spatial Series

The syntaxonomic analysis of pine forests with Acer negundo occurring on fluvio-glacial sandy deposits of Altai Krai (South-East Siberia) was made based on 93 releves. It was established that Acer negundo takes a different phytocenotic part in 2 associations, 2 variants, and 6 no-ranked communities of 4 classes and 4 orders according to the Braun-Blanquet approach. The method of detrended correspondence analysis (DCA coordination) implemented in the DECORANA software package was used to confirm the ecological and floristic integrity of the identified vegetation units. New data on the spatial syntaxa distributions depend on the complex humidity gradient, soil fertility, and anthropogenic factors. Acer negundo is most abundant and common in the communities of the Brachypodio-Betuletea pendulae class, which are characterized by habitats with moderate moistening and greater soil fertility. In the spatial series considered, according to the soil fertility and humidity gradients, we observe an increase in Acer negundo in the Vicia sylvatica – Pinus sylvestris community and an increase in the activity of mesophytes and mesohygrophytes that are more demanding to soil fertility.

Preceding Session

(Ed. note: The custom in these Symposia has been to have a summary-introductory presentation which lasts about 1 to 1.5 hours, during which discussion from the floor is minor and usually directed at technical clarification. The remainder of the session is then devoted to discussion of the whole subject, oriented around the summary-introduction. The preceding session, I-A, at Nice, followed this pattern. Christy suggested that we might experiment in his presentation with a much more informal approach, allowing considerable discussion of the points raised in the summary-introduction during its presentation, with perhaps the entire morning spent in this way, reserving the afternoon session for discussion only. At Varenna, in the Fourth Symposium, several of the summaryintroductory papers presented from the astronomical viewpoint had been so full of concepts unfamiliar to a number of the aerodynamicists-physicists present, that a major part of the following discussion session had been devoted to simply clarifying concepts and then repeating a considerable amount of what had been summarized. So, always looking for alternatives which help to increase the understanding between the different disciplines by introducing clarification of concept as expeditiously as possible, we tried Christy's suggestion. Thus you will find the pattern of the following different from that in session I-A. I am much indebted to Christy for extensive collaboration in editing the resulting combined presentation and discussion. As always, however, I have taken upon myself the responsibility for the final editing, and so all shortcomings are on my head.)

The Past

This subject, is like observing the panorama of a mountain range, magnificent towering peaks, but it doesn't take much duration of observation to recognize that they are still in the process of formation. The mountains consist of approaches, materials and methods and the rocky substance of information has accumulated to such a degree that I find myself concentrating on the foothills in the foreground in order to keep up with the advance; the edifices behind form a wonderous, substantive background. It's a short history for such an accumulation and much of it has been moved by the members of the societies that make up this International Federation. My panel of speakers are here to provide what we hope is an interesting scientific fare, based on the fact that there is a continuum of biological organization from biochemical molecules through macromolecular assemblies and cellular membranes to the cell itself. Indeed, this fact explains the whole range of towering peaks that have emerged progressively during the past 25 years.
