Abstract: Arctic Environmental Research 21(1): 1-7 DOI : 10.3897/issn2541-8416.2021.21.1.1 Authors : NR Pirtskhalava-Karpova, AA Karpov, DA Barashnin : Monitoring of the animal world is an important component in the development of world science. Observations of animals in specially protected nature areas are conducted year-round. The goal of the study was to develop electronic data collection forms for Survey123 used for ArcGIS application and to collect field data using this application tested during the field seasons 2018–2019 in the National Park Russian Arctic. Monitoring of the number of Arctic animals (white bears, walruses, seals, etc.) was carried out from the marine vessel and along the walking routes during the polar day by the state inspectors of the Russian Arctic National Park. The results of the application testing were the animal counting field data in electronic format taken during one flight of the 50 Years of Victory icebreaker, on the vessel “Altai” and during three flights of the Sea Spirit vessel. The total number of mammals obtained using the application during the 2018–2019 field seasons was 3,452 individuals, and the total number of birds was 14,457. All animal encounters are referenced by coordinates and presented on the electronic map. The Survey123 application testing during the 2018–2019 field seasons showed the efficiency of collecting animal data in electronic format which makes the data immediately available for processing and analysis. At the end of the field seasons, it was concluded that the electronic application can completely replace the hand-written register of animals. HTML XML PDF PubDate: Mon, 25 Jan 2021 15:26:00 +020
Abstract: Arctic Environmental Research 20(1): 29-36 DOI : 10.3897/issn2541-8416.2020.20.1.29 Authors : IT Kishchenko : Most species of woody plants indigenous to the Russian taiga are extremely sensitive to pollutants. However, many species of deciduous trees that grow in other geographical areas, including the genus Fraxinus, are fairly tolerant to progressive environmental pollution. For the introduction of cultivated plants into new environmental conditions, an impartial assessment of their introduction potential is required, which is possible only on the basis of comprehensive studies. The most important processes characterising the condition of plants are growth and development. The present study examined the introduction of three species of the Fraxinus L. genus to the middle taiga subzone. These were F. excelsior L., F. americana L. and F. pennsylvanica Marsh. The stems and leaves of the plants were measured once every 2–3 days over the course of two growth periods. Phenological observations were carried out between May and October over the course of 17 years. The introduction potential of the studied species was determined through visual assessment carried out in the autumn. The findings showed that the growth of shoots and leaves in the studied Fraxinus species began in late May-early June, varying between species by 1–5 days. The cessation of shoot and leaf growth in the studied Fraxinus species, which occurred in July, varied by up to ten days. The dates of onset and culmination of the growth of shoots and leaves appeared to be determined primarily by air temperature, with a year-by-year variability of 3–7 days. All the studied Fraxinus species showed a high degree of introduction potential and can be successfully used for gardening and landscaping purposes in the middle taiga subzone.

Abstract: Arctic Environmental Research 20(1): 37-42 DOI : 10.3897/issn2541-8416.2020.20.1.37 Authors : IP Belozerov, MG Gubaidullin, AV Yuriev : The question of digital core modelling appears highly relevant due to the fact that there is not always a sufficient amount of core material available from studied wells: in some cases, it is not possible to select core material (in case of loose, weakly cemented rocks); in others, such material may be completely absent. In order to create a computer model of a digital core, it is necessary to have a correct understanding of the pore space microstructure and rock lithological composition and structure, among the most important features determining the quality of sedimentary reservoir rocks. Such information can be obtained by carrying out lithological-petrographic studies of thin sections of reference (standard) core samples. The aim of the present work is to study petrographic thin sections for their further use in creating a digital core model. The article discusses the methodology and results of laboratory lithological and petrographic studies of thin sections using the available core information. The paper presents the results of laboratory studies of thin sections of terrigenous sandstones obtained from the Berea Sandstone formation (USA). The choice of the Berea Sandstone is due to its wide recognition by specialists, as well as its homogeneity, both in terms of the grain size of constituent rocks and their filtration and reservoir properties. The work also presents the results of data analysis on lithological and petrographic studies of core material from the terrigenous deposits obtained in the Timan-Pechora province in northern Russia. The research results can be used for mathematical modelling of the pore space microstructure in a digital core model. HTML XML PDF PubDate: Mon, 2 Nov 2020 10:32:14 +0200
Abstract: Arctic Environmental Research 20(1): 17-28 DOI : 10.3897/issn2541-8416.2020.20.1.17 Authors : NE Koroleva, EI Kopeina : Rare and endangered habitat types and vascular plant species were studied in the canyon associated with slope cirque “Gorodskaya shchel' (Town Crack)" in the southern part of Khibiny Mountains (Murmansk Region). Habitat types are interpreted based on a phytosociological approach (Braun-Blanquet classification). Habitat type “D4.2. Basic mountain flushes and streamsides, with a rich arctic-montane flora" of the Emerald Network (partly coincides with type 3220 “Alpine rivers and the herbaceous vegetation along their banks" of Council Directive 92/43/EEC) includes two associations: Mniobryo–Epilobietum hornemannii Nordhagen 1943 of alliance Mniobryo–Epilobion hornemannii Nordhagen 1943, сlass Montio–Cardaminetea Br.-Bl. et Tx. ex Klika et Hadač 1944, and Oxyrietum digynae Gjaerevoll 1956 of alliance Saxifrago stellaris–Oxyrion digynae Gjaerevoll 1956, class Salicetea herbaceae Br.-Bl. 1948. Habitat type “H2.6 Ultra-basic screes of warm exposures" of the Emerald Network is represented by community type Racomitrium spp.–Ranunculus glacialis (class Thlaspietea rotundifolii). These habitats harbor a number of Red Data Book species: 16 rare vascular plants including two species of the Red Data Book of Russia, four species of Red Data Book of Murmansk Region and ten species which need special attention to their state in the natural environment if the Murmansk Region occurred in the studied canyon, cirque and nearest surroundings. As the area is out of the borders of National Park “Khibiny" and has high conservation value, it is necessary to establish here the botanical nature monument.

Abstract: Arctic Environmental Research 20(1): 10-16 DOI : 10.3897/issn2541-8416.2020.20.1.10 Authors : E Romanov, C Shabanova, H Nakvasina, A Popova, H Kosareva : Increased soil acidity remains one of the important problems in world agriculture, especially relevant for the Northern territories, Traditionally, it is solved using lime ameliorants. Searching for new ameliorants that are just as effective, but at the same time are more are more accessible to certain areas is a promising direction for the development of agricultural science. Saponite water suspension can become effective ameliorant to improve acidic properties of soil on the territory of the Arkhangelsk region (Russia). This is possible due to the unique properties of saponite, its availability and the presence of large reserves in the region. This article presents the results of an experiment conducted in the Kholmogorsky district of the Arkhangelsk region (Russia) on sod-weak podzolic loam tame soil to identify the effect of saponite water suspension on acidic properties of soil under a naked fallow condition. The experiment proves the dependence of the seasonality of application, the different proportions of saponite water suspension and changes in pH and hydrolytic acidity, as well as the estimation of the most effective proportions of saponite water suspension to improve acidic properties of soil and revealed differences in the influence of seasonal application on the manifestations of the deoxidizing ability of saponite water suspension.

Abstract: Arctic Environmental Research 20(1): 1-9 DOI : 10.3897/issn2541-8416.2020.20.1.1 Authors : GS Potapov, YuS Kolosova : The fauna and ecology of bumblebees in the European North are quite well-studied. However, there is a scarcity of information about the distribution and ecology of certain species of bumblebees, especially for the territory of Northern Russia. In this study, we summarised materials concerning Bombus (Pyrobombus) jonellus (Kirby, 1802), which is typical bumblebee species for the north-western portion of the Russian Plain and surrounding areas. The studied territory includes the Arkhangelsk Region and the western part of the Nenets Autonomous District, i.e. a wide strip from taiga to tundra ecosystems. Due to the studies of materials that were collected over a period 17 years, we established that B. jonellus is widely distributed and the northern border of its range within the studied region reaches the northern part of the Kanin Peninsula. In the north-western Russian Plain, B. jonellus has been found in various types of habitats, the most common being coniferous and birch forests, secondary meadows and ruderal patches. In the Solovetsky Islands, White Sea, Russia, B. jonellus is typical on coastal heathlands. In the northern part of the studied region, B. jonellus has a tendency to forage in open habitats and visits a wide range of entomophilous plants, mostly of the family Ericaceae. Our findings highlight that the territory of the north-western Russian Plain and surrounding areas is where B. jonellus is widely distributed and abundant, being recorded in different types of habitats.
