Analysis of biometric studies data of environmentally-sensitive species of Ranunculaceae family in relation to the studies of the influence of long-term technogenic emission in the city of Baikalsk on the natural resistibility factors of plants is given. It has been proved that it is possible to use the state of cenosis populations of herbaceous mesophyte Thalictrum minus L. as a bioindicator to estimate pollution of forest ecosystems of the South Baikal Region. A change of 15-30 % of species habitus and reduction in the duration of certain ontogenetic states up to 3-15 years is registered according to degradation of environmental performance indices of a specific area. Species of average and low vitality form decreasing populations. Their dynamics leads to the change of vitality range and reduction in indicator species in the areas of high aerotechnogenic environmental stress. Statistical analysis of factors influencing formation of plants habitus has shown that the most significant ones are crown thinning, projective cover of grass stand and percentage of organic substance in the soil. Non-linear regression modeling of environmental factors influence on habitus development of Thalictrum mesophytes makes it possible to prognosticate the behavior of their cenosis parameters in conditions of environmental stress accurately.

Biotechnological methods of plants propagation have prospects for genetic conservation of wild rare and declining species. They appear to be effective in plants reproduction to produce a large number of individuals within a short time. We present here our results in production of callus culture of the endemic species Eranthis tanhoensis Erst (Ranunculaceae) from the South Baikal region.

The results of studies on the influence of agrotechnological techniques on the productivity of alfalfa (Medicago sativa), cultivation on agro-peat soils in the south of Belarus were presented. It was established that the yield of green mass on average over 4 years of life was 393.6–517.9 c / ha when sown under cover and 494.3–629.8 centners ha-1 with coverless sowing. Productivity — 56.5–75.1 and 69.5–89.7 centners ha-1, respectively. A positive correlation between the increase in the yield and productivity of the grass stand with an rise in the seeding rate and doses of fertilizers applied was noted.

This article focuses on the location of brown-headedtit (Parus montanus CONRAD VON BALDENSTEIN, 1827) on the territory southern Baikal region. The article presents literature data on the intra-landscape placement of chubby tit and gives a complete description of areas suitable for the habitat of these birds.

Mapping of hazardous geomorphological processes in the Baikal Region and its ecological and geomorphological zoning was carried out on the basis of the improved method, developed earlier by the authors. Baikal Region includes the subjects of the Russian Federation in the South Siberia and Republic of Mongolia within the boundaries of the Lake Baikal Basin. The basis of zoning are

The paper presents the results of studies aimed at the analysis and assessment of atmospheric pollution over the Lake Baikal in the summer. This information is necessary to create physical models of the formation and transfer of atmospheric aerosol fields, taking into account the physical and geographical features of the Baikal region. Measurements were carried out by a lidar «LOSA-A2» installed on the scientific-research vessel «Academician V.A. Koptyug». The vessel’s route passed along the South, Middle and Northern Baikal, from July 15, 2018 to July 26, 2018. At the same time, observations were conducted using lidar «LOSA-M2». It was located in the background area at Boyarsky stationary site (51.84° N, 106.06° E), in the south-eastern part of the lake. The results of changes in the spatial structure of atmospheric aerosol fields in background conditions and during forest fires are shown.
