Archaea is the least studied group of the reindeer rumen microbiocenosis. Although the functional load performed by this group of microorganisms in the rumen is large. Methane-forming archaea play a key role in the process of anaerobic decomposition of organic substances, the formation of methane. This study for the first time analyzed the composition of the archaeal part of the microbial community of the reindeer rumen using the T-RFLP method from various regions of the Russian Arctic. As a result, it was found that according to the estimates of the number of archaea by quantitative PCR in the reindeer rumen in the winter-spring period, on average, 108 genomes/g of archaea were observed in individuals of the Yamalo-Nenets Autonomous District, and 109 genomes/in animals from the Nenets Autonomous District Archean. Thus, in the winter-spring period, a lower number of archaea in the rumen was observed in the Yamalo-Nenets Autonomous District. According to the results of the T-RFLP method, 44 to 134 phylotypes were detected in the archaeal community of the reindeer rumen, the Shannon index was 2.02–3.80. The lowest content (up to 11.10 %) of methanogenic archaea of the Methanomicrobia class (including the families Methanosarcinaceae and Methanocorpusculaceae) was revealed in the Nenets Autonomous District, while their presence in individuals of the Yamalo-Nenets Autonomous District reached 36.33 %. Interestingly, in adults of the Yamalo-Nenets and Nenets Autonomous Districts, a significant decrease in the representation of methanogenic archaea of the Methanomicrobia class was noted by 1.38 (P <0.05) and 2.70 times (P <0.01), respectively, compared with young individuals (up to 2 years).

The article is devoted to analyzing credit instruments for increasing the financial and investment potential of the region. The place of credit instruments in the state monetary policy system is considered, and the influence of the monetary policy on regional economic processes is analyzed. Based on the analysis of the relevant research works, the thesis on different reactions of regions to significant decisions of monetary authorities while implementing the monetary policy is confirmed. Possibilities of differentiating application of the monetary policy instruments by territories in accordance with the development specifics of individual regions or their clusters are studied. It is concluded that some of the instruments (interest rates on operations of the Bank of Russia, mandatory reserve requirements, open market operations, refinancing of credit institutions) have a potential to adapt their use in the regional context. Separately, the article highlights and analyzes direct regional tools for enhancing credit activities, such as direct lending to priority areas and sectors of the economy by regional authorities, subsidizing credit rates for certain categories of borrowers, and creating regional credit organizations with governmenta participation. Based on the assessment of the principles of using the instruments to increase the financial and investment potential of the region, the article provides recommendations for choosing credit instruments for the regions of the Russian Arctic zone (Arkhangelsk region, Nenets Autonomous district, Yamalo-Nenets Autonomous district, Republic of Karelia, Komi Republic, Murmansk region, Krasnoyarsk territory, Republic of Sakha (Yakutia)). For this purpose, the features of building and functioning of the financial systems of the Russian Arctic regions, and the state and performance indicators of their banking sector were analyzed.

For the first time, comprehensive studies of the phenogenetic features of the Ural ecotype of domestic reindeer of the Nenets breed were performed. It was found out that the Ural reindeer relative to other ecotypes of the Nenets breed have smaller linear dimensions and live body weight. The studied group of reindeer was characterized by the minimum values of the majority of population genetic indicators, including the effective number of alleles (Ne = 4.422 ± 0.614), the Shannon information index (I = 1.663 ± 0.102), and the level of both the observed and expected heterozygosity (Ho = 0.561 ± 0.064 and He = 0.740 ± 0.035, respectively). It exceeded two other samples from neighboring breeding regions (Nenets Autonomous district and the Komi Republic) in the average number of alleles per locus: (Na = 9.667 ± 0.577 versus Na = 9.555 ± 0.669 and Na = 9.557 ± 0.709, respectively). Animals of the Ural population (YAM) have a closer genetic structure with reindeer individuals of the neighboring Nenets Autonomous district (NAO). The studied sample of the Nenets breed was characterized by a shift in genetic diversity towards a lack of heterozygotes, as evidenced by the positive Fis values. The introduction of genetic methods in the reindeer herding will allow improving the breeding work in the industry, revealing intraspecific genetic variation in inbreeding herds and identifying intrabreed groups of animals.

An annotated list of spider wasps collected in the circumpolar region of Western Siberia (Yamalo-Nenets Autonomous District) for the first time is given. The six species are listed, of them five species are newly recorded from Tyumen Prov. and Episyron rufipes (Linnaeus, 1758) is newly recorded from Western Siberia.

We studied in detail a moss-lichen component of Shokalsky Island vegetation for the first time and identified 79 species of mosses and 54 species and 2 subspecies of lichens and lichenicolous fungi. All species of mosses and 23 species and 2 subspecies of lichens and lichenicolous fungi are recorded for the first time for the island. The study is based on collections made in South West part of the island, in arctic tundra. We also explored the participation of the mosses and lichens in the main types of plant communities and the species distribution in 10 ecotopes. The paper describes the noteworthy findings (Abrothallus parmeliarum, Aongstroemia longipes, Arthonia peltigerea, Caloplaca caesiorufella, Catillaria stereocaulorum, Ceratodon heterophyllus, Lecanora leptacinella, Sphagnum concinnum, S. olafii) and features of bryo- and lichenoflora of Shokalsky Island.

Developing democracy institutions and citizen participation in state affairs, the world community focuses on postcolonial studies, which allow us to identify new perspectives, set new priorities in various areas, in law and public administration among others. In Arctic countries, postcolonial discourse has an impact on the methodology of research related to indigenous issues, and this makes possible to understand specific picture of the world and ideas about what is happening in the world. Moreover, the traditions of Russian state and governance are specific and interaction between indigenous peoples and public authorities should be studied with a special research methodology which would reflect the peculiarities of domestic public law and aimed at solving legal issue and enrich public policy. The objective of the paper is to present a new integrated methodology that includes a system of philosophical, anthropological, socio-psychological methods, as well as methods of comparative analysis and scenario development methods to involve peripheral communities into decision-making process of planning the socio-economic development in one of Russia’s Arctic regions — the Yamal-Nenets Autonomous District and to justify and further legislatively consolidate the optimal forms of interaction between public authorities and indigenous communities of the North. In 2020, the Arctic Research Center conducted a sociological survey in the Shuryshkararea of the Yamal-Nenets Autonomous District, which seems to limit existing approaches to identifying public opinion about prospects for developing villages and organizing life of their residents. Our proposed methodology for taking into account the views of indigenous peoples can help to overcome the identified limitations.
