The Influence of the Agroecological Resources of Crimea on thePrimary and Secondary Metabolites of AligoteGrapes

This research focused on examining the interrelationships between the natural conditions for growing grapes, as well as the quantitative and qualitative characteristics of the harvest. These are important criteria for the scientifically grounded selection of a territory for planting a vineyard, selecting varieties and determining the use of the resulting products. The characteristics of six model vineyards of the Aligote cultivar, located in various natural zones and viticultural regions of the Crimea, were analyzed. The values of climatic indicators were calculated, including the growing degree days above 10∘C (∑Т ∘С10), growing degree days above 20∘C (∑Т ∘С20), Huglin index, Winkler index, average growing season temperature, average September temperature, ratio ∑Т ∘С20/∑Т ∘С10,total precipitation during the year, total precipitation during the growing season, total precipitation in September, and Selyaninov hydrothermal coefficient. These were calculated usinggeoinformation and mathematical modeling for the locations of the analyzed vineyards. The content of the primary metabolites (total sugars, titrated acids and calculated indicators based on them) and secondary metabolites (phenolic components, oxidase activity) of grapes from the model vineyards were analyzed. The range of variation in the studied indicators within the analyzed territories was calculated, and the nature and magnitude of the relationships between the indicators were revealed. A cluster analysis of the analyzed vineyards was carried out and clusters were distinguished according to the degree of similarity in climatic parameters, as well as the content of the primary and secondary metabolites of the grapes. Keywords: grapes, agroecological factors, primary and secondary grape metabolites, ampeloecological zoning, terroir

Geoplastics of relief as a means of forming the perception of landscape compositions on the example of the Pechersk landscape park in Kyiv

Geoplastics, as a method of vertical planning, is gaining more and more popularity among landscape architects, because this method gives the landscape an aesthetic unity, expressiveness, and a peculiar feature. The paper considers the influence of geo-plastic changes in the relief on a person, the viewer's perception of the environment. These factors are extremely important in the creation and design of the park, they allow the key elements to be presented, while creating harmonious combinations in the space, it is admirable and it is this that encourages you to visit the landscape object. Pechersk Landscape Park is located on the picturesque slopes of the Dnieper in Kiev, has a landscape type of planning, which is characterized by large areas of lawns with groups of shrubs and trees, the lack of symmetry in the placement of alleys and other elements of free planning. The park zone itself covers an area of 32,92 hectares. Location in difficult terrain contributes to the use of geo-plastic tools, which can be used to improve and develop park space. The illuminated research is based on the analogy method, by means of which the analog elements of geoplastics are transferred to the results obtained during the field survey of the park territory on difficult terrain. Graphic materials were developed using the ArchiCad 21 software package based on the original cartographic data. A detailed analysis of the problematic aspects of the Pechersky Landscape Park identified the main tasks: adaptability to the needs of society, increasing the comfort of stay, improving the natural landscape, arranging natural zones of park relief. Techniques and methods for improving the territory were applied, such as terracing slopes, creating eco-chairs, using artificial relief in playgrounds. The impact of these changes on the stay of visitors and on the environment as a whole is summarized and predicted. The use of geoplastics in the context of the perception of landscape compositions will contribute to solving problematic relief and exposition aspects of the Pechersk Landscape Park, which will increase its recreational potential.

Scientific-methodical and practical principles for assessment of the key territories of the Eastern Podillya's econetwork based on the main criteria of their formation

The article presents scientific-methodical and practical principles for assessment of key territories of the ecological network of Eastern Podillya based on the main criteria of their formation. It offers the system of appropriate approaches and principles to be applied for formation of the key territories of the region's ecological network. The principle of representativeness should serve as a main criterion for selection of the key territories, however, we still advise to consider three types of such territories – biotic (botanical, zoological, mycological); geographical (landscape; biogeographical); geozoological (object; categorical; functional). Such aspects as area, size, configuration, state of internal ecological balance should play a significant role in creating the key territories, however, the qualitative and quantitative composition of protected objects, degree of anthropogenic impact on natural and man-made ecosystems and types of conservation regimes are also extremely important. Matrix representativeness, which is widely used in EU countries, should be also of great importance in forming a network of key territories. It is based on the landscape-zonal principle, where the systems of natural zoning units (biogeographical, geobotanical, floristic, forest typological, zoogeographical, physical-geographical) form the matrix of biodiversity species and landscapes. According to this principle, the basis for creation of key territories should by all means include typical (indicator) species of biodiversity, landscapes of all natural zones, subzones, regions, provinces, sub-provinces, districts. The field surveys of Eastern Podillya led us to a conclusion that a significant number of key territories do not perform a function of preserving biotic and landscape diversity. The conducted field researches allowed establishing the fact that there is a risk of losing such diversity under current ecological conditions of the region. Therefore, using the principle of representativeness, we presented a method of assessing the key territories of the Eastern Podillya's ecological network based on the main criteria of their formation. The main criteria include degree of naturalness of a certain key territory, its floristic and faunistic significance, landscape-coenotic and specific (relating to species) representativeness, purpose of a key territory, and its protected status (regime).

Geochemical differentiation of atmospheric aerosols in natural zones of European Russia

Climate and environmental changes on Earth have become modern challenges to humanity. The main factor affecting the landscapes of Russia is an increase in air temperature and a decrease in precipitation. Because of these processes, the amount of aerosols in the near-ground atmosphere of the landscapes of the ETR (European territory of Russia) increases. The aim of the study is to determine the atmogeophysical and atmogeochemical indicators that reveal the interaction of the atmosphere and the diversity of natural landscapes in European Russia. Landscape-geochemical research methods make it possible to study geosystems with the participation of all landscape components and actual migration processes, especially the atmospheric migration of chemical elements. To determine the modern atmogeochemical existence, field comprehensive studies of the potential emission of matter in all natural zones of the ETR were carried out submeridionally - in the landscapes of the steppe, forest-steppe, forest and tundra zones of the ETR. The research results show that in the submeridional profile, the mass concentration of aerosols decreases regularly from south to north, the minimum concentrations of atmospheric aerosols are observed in the forest zone, in the tundra there was a slight increase due to anthropogenic landscapes and the influence of the sea. Analysis of the chemical composition of aerosols revealed that, among the elements of global importance, aluminosilicates naturally increase to the south of the ETR as elements of clay minerals that are widespread in the Russian Plain. The maximum phosphorus content occurs in the residential area with agricultural landscapes. Sulfur concentrations are confined to the semiarid zone of the ETR, then decrease in the forest zone and increase again in the technogenic regions and the tundra belt of the Kola Peninsula, surrounded by the sea. The concentrations of chemical elements of regional and local distribution in atmospheric aerosols are more differentiated on the ETR and depend on the natural and technogenic features of each region. Thus, heavy metals are more common in the Plain territories of the forest-steppe and forest zones of the ETR and are confined to the bedrock and technogenic sources. High concentrations of calcium and strontium are associated with areas of weathering of carbonate rocks. In general, increased concentrations of atmospheric aerosols with an increased content of anthropogenic elements are observed during the western and southern transport of air masses. At the same time, the amount of rainstorm precipitation increases when these aerosols act as condensation nuclei. To assess the current state of the atmosphere at the ETR, it is necessary to continue field measurements and organize European annual and seasonal geochemical monitoring at stationary observation points.

The number of juvenile fish and fish productivity of water bodies of the Ob River basin (Western Siberia): review

The article presents an overview of published materials for the period 1963-2020, containing information on the number of larvae and juveniles of fish in different types of water bodies of the Ob River basin (Western Siberia). Data on the fish productivity of rivers and lakes of the Ob basin for steppe, forest-steppe, taiga and tundra natural zones are presented. The Ob River is the main waterway of Western Siberia. The area of the Ob River basin is 2929,000 km2, the length of the river is 3680 km. The existing pronounced differences in the nature of the relief, climate, soils, waters, vegetation of the natural zones of the Ob basin determine the features of the hydrological regime and the living conditions of hydrobionts. Accordingly, the floodplain of the Ob river with its numerous backwaters, kuryami, lakes, sorami is the main places of spawning and feeding of fish. In the course of generalization of the published materials, information was obtained on the number and features of the distribution of juvenile fish in different types of water bodies (channel pits, floodplain lakes, old trees, sores) of the Ob River basin. The results of studies on determining the fish productivity of rivers and lakes of the Ob basin of steppe, forest-steppe, taiga and tundra natural zones are analyzed.

Regional unevenness of the summer warming in the continental Arctic as an indicator of natural boundaries of northern landscapes

The authors have revealed the features of summer warming in different sectors of the Russian Arctic zone in the modern period and the near future. In connection with the considered features of the summer warming within 1991—2018, the researchers present a unique analysis of the inter-decade distribution of trends in the characteristics of the natural zones surface (vegetation index, total evapotranspiration, surface temperature, albedo). Changes in climatic conditions provide prerequisites for a change in the spectral characteristics of landscape zones, especially in the central sector of the Russian Arctic zone.

The humid and thermal impact on distribution of Sea buckthorn fly (Rhagolethis batava Hering, 1958) in Mongolia

A total of 80 species in 1834 types of Tephritidae Newman (fruit flies) were recorded in the Mongolian-Russian comprehensive and joint expedition report, which was organized in 1967-1995. In the course of an itinerary survey conducted in 2019, we have recorded the dispersion of Rhagoletis batava at 223 natural (wild) and planted sea buckthorn points in 22 soums of Bayan-Ulgii, Uvs, Zavkhan, Khovd, Selenge and Govi-Altai aimags (provinces). Accordingly, we summarized the spread of sea buckthorn fruit fly relating mostly to territories that have dry and cooler climates, while some areas are humid and cold. Based on the dispersion points, we determined the current and future changes in the distribution of this species of flies, using the MaxEnt Modeling of geographical distribution. Thermal and humidity rates that affect the flies were estimated using data collected from 18 meteorological stations and sentinel posts. These points are located in different natural zones with an average annual air temperature fluctuating from -4.8 to 3.2°С. For example, in Tes soum of Uvs aimag, Bayantes soum of Zavkhan aimag and in Tes along the Tes river basin the average annual temperature is from -3.7 to - 4.8°С; in Baitag Kharuul of Bulgan soum of Khovd aimag, along the Bulgan river basin, the warmest temperature is 3.2°С, and in other soums it is -2.4 ... 1.8°С.

Spiders of the Udmurt Republic, Russia

The long-term project "Spiders of the Udmurt Republic" (2007–2018) aimed to research spiders' regional fauna and zoogeography, diversity (including spatial and seasonal patterns) and habitat preferences. We performed the collection of spiders in all natural zones of the republic, habitats and vegetation layers, both at permanent sampling plots and through ad-hoc sampling en route. The dataset includes occurrences from 53 geographical points with 10,500 records and more than 35,000 specimens. This increases the existing data on Russian spiders on GBIF by four times, from 11,000 (excluding iNaturalist observations) to 46,000. The dataset allows for the exploration of regional fauna, local and general species distribution, spider phenology and habitat preferences for the purposes of monitoring and conservation.
