Приведено описание авторской модификации алгоритма определения численности бурого медведя на основе методики визуального количественного учета в высокогорной местности. Показано, что оптимальные сроки учетных работ в условиях преимущественно высокогорного Катунского заповедника приходятся на 1–2 декаду мая, когда бурый медведь в поисках легкодоступ...

Cadmium (Cd) is one of the most toxic trace elements. The most important sources of Cd contamination by burning fossil fuels as coal or oil and incineration of urban waste, including plastics and nickel-cadmium batteries. In all countries these sources make Cd contamination an important health issue worldwide. Cd can enter the body through smoking...

По результатам зимнего маршрутного учета 2001-2020 гг. на ландшафтной основе в геоинформационной среде MapInfo построена карта, отражающая биотопическое распределение узкоареального подвида соболя Martes zibellina avereni Bazhanov, 1943 в условиях Катунского заповедника. Для этого на основе алгоритма расчета "естественных" групп проведено ранжирова...

Abstract. Probability models of the past, current and future range of Apollo, Parnassius apollo (Lepidoptera, Papil-ionidae), in the Altai Mts are constructed by means of the maximum entropy method. Evaluation of the predictive capacity of 19 bioclimatic and 3 topographic factors has shown that the spatial distribution of the species mostly correla...

The aim of the research is a comprehensive evaluation of the character of the impact of recreational activity and tourism on the biological communities of the Republic of Altai. The article discusses the main tendencies of changes in biological communities in the Altai Mountains proper to places of high recreational load. It is shown that as a rule...

Studies of ecology and fauna are still important for studies of animal communities, important components of ecosystems of various levels. The article analyses the spatial distribution and diversity of communities and individual mammal species in the South Eastern Altai. The characteristics of land habitats and the integral ecosystem stability facto...

Tourism development directly affects territorial biological diversity. Therefore, the main objective of this study is to analyze the biological diversity in the areas with intensive impact of tourism and recreational activities in the Altai Republic. The article presents the results of field studies in the Katun Nature Reserve in the Altai Republic...

Mountainous natural complexes of Altai cross-border territory is a unique object of studies into their durability against an external impact since they represent a complex mosaic structure. Authors used an integral characteristic as an assessment factor, which allowed to determine the durability of their soil cover. First, the river layer was conve...

The major spatial changes in the communities of invertebrates in the grass cover of the Northeastern Altai and the factors determining these changes are revealed on the basis of multi-year accounts. The strength and general character of the connection between nonhomogeneity of population and environment are estimated.

Long-term field studies of day moth populations in the southeastern Altai showed that their spatial mosaicity mainly due to thermal factor related to absolute altitudes. Spatial variation of these communities is associated to a lesser degree with humidity, zonality, afforestation and share of cliffs in lanscapes. Changes in population density, spec...

An analysis of the spatial distribution of skippers (Hesperiidae) in the territory of the Russian Altai, based on the results of quantitative collections (1975-2004) and literature data, is given. The role of the main environmental factors (humidity, temperature, fodder plants) in the heterogeneous distribution of skippers by habitats is shown.
