A growth in the number of deer and an increase in their productivity are closely related to the solution of the complex problem of reproduction and rational use of deer females. Significant damage to reindeer husbandry is caused by the barrenness of northern domestic deer, the level of which has been quite high in recent years. So, in the Republic of Sakha, on 01.01.2020, the number of domesticated reindeer was 152,068, of which female deer and heifers — 71,818, offspring per 100 females — 59, business yield amounted to 52 fawns per 100 females. The causes of infertility are very diverse, as the natural and climatic conditions of the breeding zones have a significant influence on the reproductive function of reindeer. In Yakutia, the main population of northern domestic deer is bred in mountain taiga and tundra natural-climatic zones, so there are about 55 thousand deer in the mountain taiga zone and more than 65 thousand deer in the tundra zone. In this regard, the study of the peculiarities of the postpartum period course in domestic reindeer females, its morphophysiology, and behavioral reactions depending on the natural and climatic conditions of breeding is of great importance.

Abstract Domestic reindeer are bred across the Russian tundra from the Kola Peninsula to Chukotka and in the mountain-taiga zone. To understand the genetic diversity and population structure of domestic reindeer, 528 individuals were analyzed using 14 microsatellites. The sample included the Nenets breed of the Komi Republic (NEN_K, n = 42), Nenets (NEN_N, n = 148), Yamalo-Nenets (NEN_Y, n = 46), Archangelsk (NEN_A, n = 47), Murmansk (NEN_M, n = 43), Taymyr (NEN_T, n = 52) regions; the Even (EVN, n = 33), the Evenk (EVK, n = 31), the Chukotka (CHUY, n = 33) breeds of Yakutia; the Chukotka breed (CHU, n = 40) of Chukotka Region; the Tuvinian (TUV, n = 32) and Mongolian (MGL, n = 21) populations of the Tuva Republic and Mongolia. Calculations were done in R package “diveRsity,” software SplitsTree 4.14.6., Structure 2.3.4. Possibly due to permanent exchanges with animals among farms of the Nenets region and thus introduction of “foreign” alleles into the herds, a higher level of genetic diversity was found in NEN_N (HE=0.699; AR =6.086). All groups had a significant homozygote excess with the maximal value of FIS in geographically isolated populations MGL (0.326) and TUV (0.229). Neighbor-Net tree showed formation of three main clusters according to breed origin and breeding region: (1) the Nenets reindeer from different regions, (2) three breeds of Yakutia and (3) TUV and MGL populations. CHU branched individually with a distance from others. At K=11 of STRUCTURE, we observed a clear clustering of CHU, MGL, TUV, NEN_T. A middle level of admixture was detected in NEN_A, NEN_Y, NEN_M and NEN_N with NEN_K and CHUY with EVN/EVK, which formed one cluster. Here, we obtained more detailed information on genetic variability of Russian domestic reindeer, which would assist to fill current gaps in knowledge about this essential species for many indigenous peoples of the Far North. The study was funded by the RSF within Project no. 16-16-10068-P.

Bee-farming is a promising branch of the agro-industrial complex in the Russian regions including the Altai Region with all required conditions for the development of the in-dustry. Numerous melliferous plants growing in the Altai Region is good bee forage which contributes to bee-farming development. Honeybees produce first-class hon-ey varieties with an extraordinary aroma and tastes from the nectar of the local melliferous plants. According to the plan of breed zoning, the European dark bee (Apis mellif-era melliferaL.) is recommended in the Altai Region. Intro-duced to West Siberia in the second half of the 18th centu-ry, these bees have adapted well to the local climate and settled in different natural zones. The comparison of the morphometric and economic indices of the Altai population with purebred individuals will make it possible to determine their position in the breed composition of honeybees. The data on the exterior characteristics of bees and the compo-sition of 2 honeybrands collected in the mountain-taiga zone of the Region is discussed. It was found that the bees of the Altai population, in terms of measured indices (the average proboscis length -6.2 mm; tergite 3 width -5.0 mm; cubital index -59.5%, negative discoidal dis-placement in 100% of individuals, etc.) were consistent with the standard of the European dark bee. Pollen study of 2 brands of centrifuged honey showed that the main pollen belonged to the plants of the Umbelliferae family (39.4%) in one sample and Compositae (56.5%) in another sample. The rest of the pollen was found in insignificant quantities and belonged to the plants of the following families: Rosaceae, Onagraceae, Labiatae, Fabaceae, Crucifers and Boraginaceae.

The purpose of the research is to study the water-physical parameters of the soil, on the basis of which it is possible to analyze the moisture regime and draw conclusions about the applied innovative technologies. The results of the experiments; set according to the developed recommendations by the employees of the Altay Botanical Garden. The article provides data on the water-physical properties of the soil: density, humidity and maximum field moisture capacity. The results of the experiments showed that with the help of the «Akvasorb» hydrogel, it is possible to regulate the water regime of soils and increase the moisture reserves available to plants in conditions of water scarcity. Thus, the addition of the preparation at a rate of 1.5 kg/m3 and 2.0 kg/m3 helps to retain the greatest amount of moisture in the soil from 15 % to 24 % across all horizons. These same norms increase the water reserves in the oil, especially in the spring and improve its density. All this contributes to a better development of plants.
