This article analyses abundances of seven Poecilus and Pterostichus species sampled from 836 forest sites located in five geographical regions of the steppe zone of Ukraine. The abundances are analysed in relation to eight forest conditions. New information about associations of the following five species was found. Poecilus versicolor was most abundant in sparse forest sites and on moist sandy soil. Pterostichus melanarius reached its maximum abundance on sites with a thick litter layer, mesohygrophilous condition, clay soils and a sparse herbaceous layer. Pterostichus niger reached maximum abundance in forests with mesohygrophilous and hygrophilous conditions and on sandy loam soils. Abundance of Pterostichus oblongopunctatus was at the highest on sites with a closed tree canopy, a thin litter layer and loamy soils of average salinity. Pterostichus ovoideus was most abundant in forests with low to average litter depth, hygrophilous conditions and loamy soils oflow to average salinity. For Poecilus sericeus and Poecilus cupreus the results ofthis study agreed with the published information.

We sampled beetles in different regions of Russia (Tatarstan Republic, Mariy El Republic, Udmurtia Republic, Kemerovo, Sverdlovsk, Stavropol, Cis-Ural provinces) at sites which varied in the level of anthropogenic impact and vegetation. We used linear models to clarify how urbanization affected body size variation in studied species. All of them were palearctic generalists – Carabus granulatus, Carabus cancellatus, Pterostichus melanarius, Pterostichus niger, Poecilus cupreus, and only Carabus aeruginosus was a Siberian one. Beetles we measured for six dimensional traits. In a whole 12000 specimen have been analyzed. Results showed that different traits of Ground Beetles can response to urbanization in opposite directions: e.g. in some studies species factor “city” decreased elytra length, but increased its width and vise versa. Effect of “city” and “suburbs” factors had different directions, e. g. in a given species body size decreased in cities but in suburbs it increased and verse versa. Cognate species, which occupy similar ecological niches, have responded to urbanization in opposite directions. Females and males can respond to urbanization in opposite directions, the latter lead to the significant body size sexual dimorphism in the gradient of urbanization.

Abstract The aim of this study was to identify the role of field margin habitats in preserving the diversity and abundance of ground beetle assemblages, including potentially entomophagous species and those with conservation status in Poland. Research material was collected in 2006–2007 in four types of margin habitats – a forest, bushes, ditches and in two arable fields. Insects were captured into pitfalls, without preservation liquid or bait added to the traps. Traps were inspected twice a week, between May and August, and one sample was a weekly capture. In field margin habitats the most abundant species were Limodromus assimilis, Anchomenus dorsalis, Pterostichus melanarius and Carabus auratus. A lower abundance of species was noted on fields, with dominant Poecilus cupreus and P. melanarius. The group of zoophagous carabids found in our study includes 30 species from field margin habitats, i.e. 37.5% of all captured Carabidae taxa and 58.3% of all specimens. The share of aphidophagous species was 84.9% among bushes, 86.7% near ditches, and 88.0% in the forest habitat. Several species captured during the study are under protection in Poland. These include the partly protected Carabus convexus, which also has the status of near threatened species, the partly protected Calosoma auropunctatum, and Broscus cephalotes. Considering all the investigated field margin habitats, ground beetles were most numerous in the oak-hornbeam habitat, defined as bushes, formed predominantly by Prunus spinosa, Crataegus leavigata, Sambucus nigra and Rosa canina. Thus, this habitat was the most important reservoir/refugium for the ground beetles.

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 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 article provides a predictive assessment of longevity of Ulmus pumila L. stands in the Astrakhan Zavolzhye. The effi and expediency of renewable logging for rejuvenation and increasing the longevity of plantings in the semi-desert were confi The classifi of ecotopes of the Astrakhan Zavolzhye on suitability for cultivation of protective and shadow elm plantings on pasture lands was developed and presented. In the Caspian region, Ulmus pumila became widespread in forest reclamation of semi-desert lands in the 1950s. Since then, till the beginning of the 1990s, Bogdinskaya research agroforestry experimental station laid on the sandy massifs about 1 thousand hectares of Ulmus pumila L. plantings, which currently amounts to 1824 %. The long-term practice of using protective shade Ulmus pumila umbrellas has shown their signifi ecological effect on functioning pastures. The aim of the research was to develop an improved technology for creating long-lived protective shade stands of Ulmus pumila on degraded pastures of the Astrakhan Zavolzhye. The research was carried out using generally accepted methods of stand forest taxation by A.P. Anuchin (1961), 1. Bitvinskas (1974) and A.S. Manaenkov (2001). Soil conditions were studied by drilling sounding to 3 m depth. The results of the research revealed that the longevity of wood species in the dry-steppe zone was determined mainly by two factors: productive moisture in the soil and salinity level. The most favorable growing conditions for Ulmus pumila were unsalted (to a depth of at least 3 m) brown sandy soils, sandy loam soils, dark-colored swale soils with periodic redistributed accumulation of moisture. In arid conditions of the Astrakhan Zavolzhye in island plantations (group of trees, umbrellas, 0.51 ha parts of forest area) and optimal growing conditions without logging and reforestation, Ulmus pumila lives up to 6070 years.

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 article deals with the morphological features of the profile and slopes of ravine systems developed in sand deposits of the southern part of the Volga Upland. The author notes that the southern part of the Volga Upland is a vast inter-river space bounded by the river valleys of the Don and the lower reaches of the Ilovlya river in the west and the Volga river and Volgograd reservoir in the east. This area has a potential for water and wind erosion. This is determined by the features of the geological structure (the development of Cenozoic Eocene-Oligocene marine deposits represented by alternating layers of clays, siltstones, sandstones and sands and Neogene-Quaternary sand-loam covers), as well as hilly type of terrain. The density of the erosion net here is 0.8–1.0 km/km2. The ravine and river valleys of the territory under consideration are typified by the age and morphological criteria into 4 types: middle and late Pliocene valleys of the Don drainage basin; Pleistocene valleys of widespread distribution; late Pleistocene valleys of the Don drainage basin; modern Holocene erosional forms. Broad floodplains with sandy loam alluvium, flattened valley slopes, and trough-shaped cross-sections are noted as common features of the structure of ravine and river valleys. The role of deflation and water erosion in the evolution of the slope microrelief of erosion forms is analyzed. The role of ravine systems in the formation of natural-territorial complexes of psammophytic steppes with a significant share of rare plant species, as well as the spread of bayrachny forest in the dry-steppe zone is noted. The predominant role of such natural-territorial complexes as psammophytic sagebrush-cereal sparse steppes on the sodsandy soils of the Don above-floodplain terraces; sparse dry sheep fescue and white artemisia steppe on the light mechanical composition of the soils of the Ergeninsk sands on the ravine slopes is noted. Among the intrazonal natural-territorial complexes, ravine and floodplain poplar-oak and old-growth aspen-poplar forests are distinguished.

The physico-chemical properties of soil vary with the variation in the topographic features, climatic conditions and forest types. In any forest ecosystem, both vegetation and soil influence each other through nutrient cycles. The altitudinal variation in soil physico-chemical properties was analyzed in a temperate forest (Radi forest) of Upper Yamuna Forest Division in Uttarkashi district of Uttarakhand (Western Himalaya, India). A total of three forest sites were selected at different altitudes (the lower, middle, and upper) to collect composite soil samples from each site covering 0–10 cm, 11–20 cm and 21–30 cm depths. The textural class of the soils was sandy loam. The colour of the soil samples varied from brown to very dark brown. The water holding capacity (r = 0.994), soil organic carbon (r = 0.967), organic matter (r = 0.966), nitrogen (r = 0.993), phosphorus (r = 0.982) and potassium content (r = 0.994) had positive correlation with altitude whereas negative correlation was observed between altitude and soil pH (r = -0.983) in the study. The present study concludes that soil physico-chemical properties in temperate forests of Uttarakhand Himalaya vary significantly with variation in altitude.

ABSTRACT The expansion of silviculture in Brazil, and the consequent intensive practices for soil preparation with high demand for fertilizers require sustainable nutrient management of forest sites. The objective of this study was to quantify the biomass and the micronutrient stocks of a 60-month-old Eucalyptus dunnii stand established in Alegrete, Rio Grande do Sul. The stand was established in a Rhodic Paleudult soil with low fertility and texture varying between sandy loam and sandy-clay loam. For the sampling of stand biomass, twelve trees were harvested, sectioned at ground level, and subsequently fractionated into the components roots, leaves, branches, stembark and stemwood to determine the dry mass and micronutrient content. The total biomass of the stand was 67.49 Mg ha-1, with mass allocation in descending order from: stem wood > root > bark > branches > leaves. Total micronutrient stocks for boron (B), copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) were 562.57, 401.46, 9913.28, 31877.82, and 766.96 g ha-1, respectively. In addition, we found greater accumulation of Zn in the wood, high Mn accumulation especially in the bark, and high Fe content in the roots. Therefore, based on these micronutrient levels and their allocation between biomass fractions, we emphasize that the practice of retaining forest residues on-site after harvest is essential for forest nutrition through nutrient cycling and for soil conservation and fertility.
