Based on the material of Macrolepidoptera, high percentage of in the taiga and tundra biota of subboreal geographical elements – one of the main biogeographic features of the European North-East of Russia – is considered. It is shown that over 50 species of Lepidoptera from 11 families have peripheral area covers in various extent taiga zone and the southern parts of Hypoarctic zone, and the area of their ecological optimum situated in the subboreal forest and steppe zones. In consideration of peculiarities of the natural process, the analysis of the landscape-zonal distribution of Lepidoptera species suggests that the penetration of subboreal species was began and gradually took place during the warm periods of Holocene. A few groups of Holocene climatic relicts have been preserved in various areas of the taiga and the foresttundra zones. At the present time the most of subboreal species of Lepidoptera in the European North- East of Russia are new and actively distributing in anthropogenic habitats.

The results of a long-term studu of the flora of technologenichabitats of the taiga zone of the Komi Republic are summarized. An annotated list of vascular plants is presented, including 406 species from 222 genera and 52 families. For each of them, it is indicated that they belong to a life from, an element of the flora and type of area, an ecologicsl group, zonal and ecotopic affinity. Data on the taxonomic composition of vascular plants, the biomorphrological, geographical, and ecological structures of synanthropic flora, the diversity of synanthropic plant communities, and the stages of vegetation restoration in disturbed areas are presented.

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.

The results of floristic classification of technogenic vegetation (alliance Chamerio angustifolii–Matricarion hookeri A. Ishbirdin et al. 1996, order Chamerio–Betuletalia nanae Khusainov et al. in Sumina 2012, class Matricario–Poetea arcticae A. Ishbirdin in Sumina 2012) conducted by the Braun-Blanquet method (Braun-Blanquet, 1964; Mirkin, Naumova, 1998) are given. 98 geobotanical relevés, made in 1981–2013 on areas of oil fields and suburbs of the Usinsk city (Komi Republic) (56–60о N, 67–66о E), were involved into analysis (Fig. 1). The ecological parameters like moisture (F) and mineral nitrogen soil enrichment (N) were assessed using the Ellenberg ecological scales (Ellenberg, 1974).

The specificities of temperature regime of automorphic clayey soils forming under the suffruticous and shrub vegetation within the zone of tundra and forest tundra in the European North-East were studied. As the objects of investigation we chose the organic cryometamorphic soils and cryometamorphic gleezems; in the both soil types the CRM cryometamorphic horizon is developed. The soils are formed in conditions of long-termed seasonal freezing at the absence (deep occurrence) of the permafrost rocks. The dynamics near the zero temperatures (zero curtains) is characterized. The hypothesis, concerning the role of zero curtains in the sustaining of the specific angular-grainy structure within the mass of cryometamorphic horizons is formulated. The mass of cryometamorphic horizons and the depth of present-day zero curtains, which observed at the long-term seasonal soil freezing, correlate to each other. The impact of suffruticous and shrub vegetation on the specificities of winter and summer soil temperature regime is determined. We discovered that the main differences between the soils developing under suffruticous and shrub vegetation tundras are stipulated by the different intensity of the snow accumulation within these areas. The soils that are developed under the shrub vegetation are warmer than soils developed under the suffruticous tundra, where permafrost may occur at the depth of 2-3 cm. In general, seasonaly freezing tundra soils are located in the middle of the range of the automorphic clay loamy soils in the tundra-taiga ecotone of European North-East of Russia, and occupy the niche between permafrost tundra and non-permafrost north taiga soils.

For the first time there is reconstructed the history of creation of the Memorial Flat of the Doctor of Geological and Mineralogical Sciences, Professor Andrey Yakovlevich Krems, Hero of Socialist Labor, Laureate of two State Prizes of USSR (Ukhta town, Komi Republic). There is presented the characteristic of his private library, which reflected his professional interests and which he collected for several decades. A.Y. Krems developed and implemented mine oil extraction method, discovered several oil and gas fields of global impact and contributed to the industrial development of the European North-East.
