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.

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.

The total concentrations of metals (Fe, Mn, Cu, Ni, Cr, Sr) and their mobile forms extracted by an ammonium acetate buffer (pH = 4,8) were studied in soils samples collected from Nadym-Pur interfluve (West Siberia), near the northern limit of the taiga zone. The heavy metal content was determined in 55 background soil samples and in 25 pyrogenic ones. Gross content was determined on a spectrometer "SPECTROSCAN MAX-GV" using X-ray fluorescence analysis. Mobile forms of metals were determined on a ContrAA 700 atomic absorption spectrometer by flame and electrothermal methods. The statistics are calculated using the Excel software package. The study confirmed the weak accumulation of metals in the soils of the northern regions of Western Siberia. The total content below the soil world average for Fe is 5 times, Mn – 3 times, Sr – 2 times, Cr – 1,4 times. The content of mobile forms varies widely depending on the amount of organic matter. The percentage of mobile forms of metals from the total content was: Cr – 0.84%, Fe – 1,2%, Sr – 3,8%, Mn – 8,7%, Ni – 15%. In the profile of podzols, the distribution of mobile forms of metals has an eluvial-illuvial character. Mn and Sr accumulate intensively in the surface organogenic horizons, and the Fe content increases in the BF horizon. Minimum values are marked in horizon E. In pyrogenic soils, there is an increase in the content of mobile forms of metals due to the intake of ash. Metal content usually not exceeded the maximal permissible concentrations for soils.
