Zonal and Zoogeographic Characteristic of the Ant Fauna (Hymenoptera, Formicidae) of UkraineOne hundred fourty ant species belonging to 38 genera of 5 subfamilies are known to occur in Ukraine nowadays. All the species are attributed to 16 zoogeographic complexes that are grouped into three faunogenetic classes. Comparative zonal and zoogeographical analysis of the fauna of different geographical regions of Ukraine has revealed their essential heterogeneity. The ant fauna of the Forest-Steppe zone is not original. At the same time, it is not transitive between the faunae of the Forest and Steppe zones. Ant fauna of the Forest-Steppe is related to those not the Steppe but the Forests zones, and the Forest-Steppe can be included in the southern subzone of a Forest zone of t Europe.

The results of a comprehensive analysis of the microelement composition of soils — B, Co, Cu, Mn, Mo, Ni, Zn and plants — Ag, Co, Cu, Mn, Mo, Ni, Pb, Zn (oak (Quercus robur L.), pine (Pinus sylvestris L.) perennial grasses — Kupena (Polygonatum multiflorum (L.) All.), wheatgrass (Elymus repens (L.) Gould)) of natural reserve belonging to different physical and geographical zones — Polessky reserve (mixed forest zone), Roztochya reserve (broad-leaved forest zone), Kanevsky reserve (forest-steppe zone), the reserve «Askania Nova» (steppe zone), the Chernogorsk massif of the Carpathian Biosphere Reserve (KBR, Ukrainian Carpathians), which are proposed to be considered as background. It was found that in the soils of mixed and broad-leaved forests and the Chernogorsk massif KBR with an increase in the content of gross forms of Co, Cu, Ni, Zn, the content of their mobile forms increases, this dependence is inverse in the soils of the steppe zone, which is associated with a decrease in soil acidity and mobility microelements A positive correlation was revealed between the humus content in soils and Zn, Co (gross and mobile forms) and negative — B, Mo in the soils of all reserve zones. It was found that the greatest biogeochemical activity is characteristic of plants in the zone of deciduous forests — oak leaves (Quercus robur L.) and pine needles (Pinus sylvestris L.).

The purpose of the publication is to present the results of the study of anthropogenic changes in the landscapes of the Forest-Steppe zone of Ukraine, implemented by assessing the indicators of landscapes anthropogenic transformation, their diversity and fragmentation. The basic research methods are methods of geospatial GIS analysis and decoding of remote sensing data of the Earth, geoinformation mapping. According to the indicators of anthropogenic transformation of landscapes at the level of physical-geographical regions and districts of the Forest-Steppe zone, the features of changes for the period 1992-2018 are determined. The results of assessment of anthropogenic changes in forest-steppe landscapes of Ukraine show that in 1992 as well as in 2018 the vast majority of the landscapes of the territory are strongly and excessively transformed by anthropogenic activity. Such patterns persist, despite the fact that during the analyzed period in part of the investigated area there is a certain decrease in anthropogenic pressure on landscapes. The regular relations between the indicators of anthropic landscape diversity and fragmentation of landscapes are determined, which corroborates to their certain conditionality by the degree and nature of anthropogenic transformation of the territory. The novelty of the study are the proposed methods of spatial and temporal changes in landscapes estimating and identifying such changes in landscapes at the level of physical and geographical regions for the period 1992-2018 and revealing trends in the structure of land use, especially agricultural lands, forests, built-up territories as the leading types of land use in the Forest-Steppe zone of Ukraine.

The comparative analysis of floristic composition of the Russian Plain center broad-leaved forests of the alliance Carpinion betuli Issler 1931 em. Meyer 1937 was carried out by means of detrended correspondence analysis (DCA) and direct ordination along ecological factor scales. The three associations representing the proper zonal units of the area, namely Querco-Tilietum cordatae Laivinš 1983 in the hemiboreal forest zone, Aceri campestris—Tilietum cordatae ass. nov. hoc loco in the broad-leaved forest zone, and Aceri campestris—Quercetum roboris Bulokhov et Solomeshch 1991 in the forest-steppe zone are characterized. Although all the forest stands described are small geographically isolated fragments, their floristic composition demonstrates the existence of syntaxonomic continuum and seems to be influenced by landscape features and anthropogenic disturbance just as strong as by zonal climatic factors. As a result of the undertaken analysis, the syntaxonomical revision of the Central-Russian broad-leaved forests of the alliance Carpinion betuli Issler 1931 em. Meyer 1937 is proposed.

The morphological variability of the aerial vegetative and generative organs of Melilotus officinalis in the ecotone communities of the forest-steppe zone, the forest zone of the Republic of Tatarstan including desecrated parts of the forest zone was studied. The ascorbic acid content in various parts of the plants growing in these habitats was also analyzed. It was revealed that the realization of the morpho-physiological potential of plants was determined by the conditions of botanical-geographical zones. The sweet clover, growing on black soils under the conditions of ecotone communities of the forest-steppe zone, was found to have higher indicators of “total biomass”, “biomass of leaves”, “biomass of inflorescences”, etc., as compared to the plants from similar communities growing on gray soils of the forest zone. Under the conditions of the ecotone communities of the forest-steppe zone, the content of ascorbic acid in all parts of the plant was also higher. Melilotus officinalis, growing in the conditions of a desecrated soil layer, was characterized by the maximum realization of its biomorphological potential with a low value of the coefficient of variation (CV), which reflected a stronger homogeneity of the samples. In the plants growing under extreme conditions, a sharp increase in the concentration of ascorbic acid in all parts was observed, which could be considered as an important mechanism for the adaptation of the species to survival under conditions of a sharp temperature difference of the substrate. Along with an increase in the generative period, an important component of the species adaptation was the low correlation between the indicator “biomass of inflorescences” and the concentration of ascorbic acid in inflorescences, “biomass of inflorescences” and the concentration of ascorbic acid in the leaves, which reflected the stable process of formation of the generative system of sweet clover. All coenopopulations were characterized by an incomplete ontogenetic spectrum with an absolute maximum on the plants with the middle-age ontogenetic status (95%).

A review of the ground beetles of the Ukrainian fauna is given. Almost 750 species from 117 genera of Carabidae are known to occur in the Ukraine. Approximately 450 species of ground beetles are registered in the Carpathian region. No less than 300 species of ground beetles are found in the forest zone. Approximately 400 species of Carabidae present in the forest-steppe zone are relatively similar in species composition to those in the forest territories. Some 450 species of Carabidae are inhabitants of the steppe zone. Representatives of many other regions of heterogeneous biotopes such as forest, semi desert, intrazonal, etc. can be found in the steppe areas. The fauna of Carabidae (ca. 100 species) of the lowlands of southern Ukraine (sandy biotopes), situated mostly in the Kherson region, is very peculiar. The fauna of the Crimean mountains contains about 300 species. Conservation measures for the Carabidae are discussed.

Background. Trypsin-inhibiting activity (TIA) is one of the factors of plant immunity. This factor provides the presence of general non-specific systemic resistance. Representatives of the genus Hedysarum L. are promising medicinal and high-protein fodder plants with high TIA in the leaves. High TIA values in the aboveground part of plants lead to a decrease in protein assimilation by animals. Therefore, identifying the differentiation in the features of TIA seasonal dynamics will make it possible to use the potential of these species most effectively under the conditions of Southern Siberia.Materials and methods. TIA in the leaves of mature generative plants of Hedysarum theinum Krasnob. and H. flavescens Regel & Schmalh. was analyzed. H. theinum is a rare species for Siberia; H. flavescens is a settled one in the forest-steppe zone of Western Siberia. The studies were conducted with H. theinum in 2010 under natural conditions (Altai Republic) and in cultivation (forest zone of Western Siberia). In 2017, H. theinum and H. flavescens were studied under cultivation in the forest-steppe zone of Western Siberia. The research method was based on the spectrophotometric measurement of the optical density in protein substrate (BAPA) decomposition products under the effect of trypsin (at 405 nm). Bovine trypsin manufactured by ISNBiomedical (USA) was used. BAPA (Na -benzoyl-DL-argininep-nitroanilide) served as a substrate.Conclusions. The TIA values in the flowering phase of seasonal plant development reached their maximum only under favorable conditions: in Altai Republic for the leaves of H. theinum, and in the foreststeppe zone of Western Siberia for H. flavescens. TIA values in H. theinum did not increase during flowering in the forest zone of Western Siberia and significantly decreased in the forest steppe. In view of these findings, these two species may be recommended for practical utilization in this phase of seasonal development.

The plot of study is Cheboksary and its suburbans and located on the joint of two landscape zones: a forest zone and a forest-steppe zone. The border between the zones goes along the Volga River, which establishes favourable environment for recreation. There has been observed slope type of areas on the right bank of the Volga River of the Cheboksary and Kuybyshev Reservoir. It has 3º and more incline, with washed-off soil and broadleaved woodland (relict mountainous oak woods), subjected to considerable land-clearing. In the immediate bank zone of the Volga River, where abrasive-soil-slipping and abrasive-talus processes mostly develop, the main types of natural areas have been marked out: 1) Abrasive landslide cliffs at the original slopes of Volga Valley of 60º steepness, more than 15 m high, with permanent watering as a result of underground waters leakage; 2) Abrasive cliffs of terraces above flood-plains of 2 m high; 3) Abrasive cliffs of original slope of the valley of the river Volga of 2 m high, with distinctive abrasive niches in the lower part of the slope or temporary concentration of caving demolishing material. Left coast is lowland plain, the part of taiga landscape zone. Low terraces above flood plain of Volga are formed by sand with loam layers, with sod-podzol sandy and sandy loam soil in combination with marshy soil, with fir-pine forest, with from lichen bogs to sphagnum bog; in lowlands, on old felling plots, on abandoned peat mines deciduous forests with mostly birches and aspens prevail.

The work submitted in this paper presents the first checklist of the ant species of the Segura River Basin based on a review of specific literature and biological material collected during field work conducted from 2012 to 2017. Our findings recorded 110 species belonging to 30 genera of ants and twenty two of these species were recorded for the first time in this area. The zoogeographical composition is dominated by the species of the Mediterranean zone (75.2%), followed by the mixed and deciduous forest zone (19.1%). The most important zoogeographic elements are: Iberian (20%), Holomediterranean (17.1%) and West-Mediterranean (13.3%). There are only six cosmopolitan species (5.71%). There is a greater proportion of species from the mixed and deciduous forest zone in the high-mid altitudes in the Segura River Basin, where the climate is cooler, and more humid. The Euro-Caucasian and Euro-West Siberian elements seems to be more associated to the more humid forest, whilst the Euro-Caucasian elements seem to be more associated to ecosystems more similar to the forest-steppe zone. The existence of these different zoogeographic origins in this area is probably linked with: the position between Africa and Europe; the complex geotectonic, paleogeographic, and paleoclimatic history during the last 7 My; the complex geomorphology; and the high climate and habitat diversity. Based on ant studies and other taxa, possible explanations of the zoogeographic origin of these ant chorotypes are proposed.

The comparative analysis of floristic composition of the Russian Plain center broad-leaved forests of the alliance Carpinion betuli Issler 1931 em. Meyer 1937 was carried out by means of detrended correspondence analysis (DCA) and direct ordination along ecological factor scales. The three associations representing the proper zonal units of the area, namely Querco-Tilietum cordatae Laivinš 1983 in the hemiboreal forest zone, Aceri campestris—Tilietum cordatae ass. nov. hoc loco in the broad-leaved forest zone, and Aceri campestris—Quercetum roboris Bulokhov et Solomeshch 1991 in the forest-steppe zone are characterized. Although all the forest stands described are small geographically isolated fragments, their floristic composition demonstrates the existence of syntaxonomic continuum and seems to be influenced by landscape features and anthropogenic disturbance just as strong as by zonal climatic factors. As a result of the undertaken analysis, the syntaxonomical revision of the Central-Russian broad-leaved forests of the alliance Carpinion betuli Issler 1931 em. Meyer 1937 is proposed.
