The article presents the results of an expert assessment of the thinning out of forest stands on the territory of the N district of the Kirov region based on field studies. Fieldwork consisted of recalculating and measuring the diameters of stumps left after felling trees, establishing their species composition and quality condition to determine the volume of harvested wood in the context of species. The stumps found were identified as pine (70 %), spruce, birch, and aspen.The authors reveal that the release forest cutting was carried out within the boundaries of the designated cutting area with an excess of the established volume of wood harvesting for the prime breed (pine). The volume of felled pinewood exceeded 2.5 times; for other species, these data is more than 70 % lower than declared. At the same time, the total actual volume of the withdrawn wood does not exceed the data of the forest declaration. Based on the revealed violation of the forest legislation and the relevant regulatory documents, the authors have calculated the amount of damage caused to the forest plantation due to illegal logging of pine wood in the volume of 297 m3. The damage amounted to more than 4 million rubles.

Capabilities of the remote sensing methods for making maps of actual and potential vegetation, and assessment of the extent of anthropogenic transformation of rangelands are presented in the paper. Study area is a large intermountain depression, which is under intensive agricultural use. Color photographs have been made by Aircraft camera Wild Heerburg RC-30 and multispectral scanner Daedalus (AMS) digital aerial data (6 bands, 3.5m resolution) have been used for analysis of distribution and assessment of the state of vegetation. Digital data were processed using specialized program ENVI 3.0. Main stages of the development of cartographic models have been described: initial processing of the aerial images and their visualization, preliminary pre-field interpretation (classification) of the images on the basis of unsupervised automated classification, field studies (geobotanical records and GPS measurements at the sites chosen at previous stage). Post-field stage had the following sub-stages: final geometric correction of the digital images, elaboration of the classification system for the main mapping subdivisions, final supervised automated classification on the basis of expert assessment. By systematizing clusters of the obtained classified image the cartographic models of the study area have been made. Application of the new technology of remote sensing allowed making qualitative and quantitative assessment of modern state of rangelands.

The article presents research in the field of quality management by suppliers of dairy whey to a bakery enterprise in the Omsk region. The general assessment criteria are systematized in the form of a tree diagram, which makes it possible to identify them depending on the target orientation. When evaluating suppliers, such fundamental elements as the quality of purchased raw materials, their cost and timeliness of delivery were taken into account. The results of an expert assessment of the organoleptic parameters of serum, controlled physicochemical parameters and subsequent regression analysis made it possible to establish their compliance with the requirements of regulatory documents. A comprehensive assessment of the possibilities allowed us to give an objective assessment, as well as to make a decision on choosing in favor of one of the suppliers.

SummaryThe Sahel in West Africa is a major wintering area for many western Palearctic migrants. The breeding populations of many of these have declined over the past 50 years. However, there have been few intensive field studies on migrant ecology in the Sahel and these were generally within a very restricted area. Consequently our knowledge of the distribution of species within this extensive area and the habitat associations of these species is limited. Understanding these habitat associations is essential for the effective conservation management of populations. We brought together a group of experts and consulted a wider group by email to assess the main Sahelian habitat types used by 68 African-Eurasian migrant bird species. Those species that showed strongest declines during 1970–1990 were associated with more open habitats than those newly declining during 1990–2000, when declining species were associated with habitats with more shrubs and trees. Populations of species that winter in the Sahel are generally stable or increasing now as rainfall has increased and is now near the long-term average for the Sahel. Those which use the Sahel only as a staging area are, in many cases, in rapid decline at present.

The study of silts settling nature in reservoirs and assessment of their accumulation volume are of significant importence and have direct relation to the water balance, evaluation of the actual volume for the reservoir regulation, and effective use of water resources. The purpose of this work is determination of accumulated amount of sediments and their settling pattern along the Khachen reservoir in the Republic of Nagorno Karabagh on the basis of analytic and field study. During 2012-2013 a number of field studies have been carried out designed to elucidate conditions under which mud and silt carried by the river are formed, their volume, grain-size composition, and nature of their accumulation over 50 years of the Khachen reservoir operation. In the presented developments data on water and silt flows, actual coordinates of the Khachen reservoir bottom and the banks and grain fineness measurements have been used. The study results permit to arrive at the conclusion that comparison of analytic analysis and field measurements enables to reliably evaluate the Khachen reservoir sedimentation regime, to refine geometrical characteristics of the accumulated sediments and make scientific prognostication on the further change of usable storage of the reservoir and the life of the dam and power station.

Despite the growing trends in quantitative field studies on tropical snake assemblages around the world, Asian tropical snake assemblages have remained less profoundly studied. A snake assemblage in an altered tropical forest-plantation mosaic in Bangladesh was studied for six months. Data were collected on the species composition and their relative frequency of occurrence. On the basis of these data, some major patterns highlighted by earlier studies on tropical snake ecology were tested. More specifically, we tested, the existence of: (1) non-random habitat niche partitioning, (2) the energetic equivalence rule, and (3) different mean body sizes among snake guilds, with distinctly smaller body sizes being expected among the subterranean species. A total of 374 specimens belonging to 34 different species were collected. High mean habitat niche overlap among species was observed, and there was no apparent non-random niche partitioning by snakes either considering all species together or dividing them by guild. The ‘energetic equivalence rule’ was verified, with larger species being less abundant than smaller species. Body sizes differed significantly across species’ habits, with subterranean species being not only significantly smaller but also revealing the least interspecific variation, and terrestrial/arboreal species showing the greatest interspecific variation. Overall, tropical Asian snake assemblages seem to be similar to tropical African snake assemblages in terms of their general organization.

Abstract The Guerrouche forest is home to a fairly important flora heritage which offers this massif a forest cover by the presence of quite remarkable forest stands, from a floristic point of view by the presence of natural vegetation characterized by a diverse flora. This study aims to quantify the floristic diversity of the vegetation associated with the three main tree species (zeen oak, cork oak and afares oak) that inhabit the Guerrouche forest on the basis of distributed floristic surveys, according to a sampling strategy. stratified and systematic, which took into account the species present in each type of tree stand. The floristic surveys thus carried out, numbering 55, made it possible to establish a list of a floristic list made up of 172 species, which belonged to 69 genera and 45 botanical families. Of these, 42 were endemic species, including 4 specific to the study area. The number of rare and very rare species was 70 taxa. The study also revealed the clear degradation of the genus Erica of this ecosystem. Analysis of the overall chorological spectrum showed a dominance of Mediterranean species (209 species), with a dominance (82.3%) of species that were therophyte species. The forest stands of the genus Quercus inhabiting the Guerrouche massif must be supported by the authorities to preserve and conserve this forest heritage against fires, illegal logging, etc. The results of this study will be the subject of development actions and rational management of these natural forest ecosystems.

The article on the observations of weather stations in the south-west of the Chernozem (Black Earth) zone of Russia checks the main hypothesis about the increase in the maximum daily precipitation which is the basis for calculating the maximum water consumption when designing reservoirs of hydraulic structures on small catchments. Statistical calculations showed a clear regional trend towards an increase in the maximum daily precipitation over time. Studies have confirmed a significant asymmetry in the distribution of their values, the ratio between the coefficients of asymmetry and variation ranges from 2 to 5. It isnoted that there is currently no sufficiently accurate method for determining the coefficients of asymmetry, therefore, approaches to their expert assessment have been proposed. It isrecommended to estimate the normative values of the maximum daily precipitation for erosion calculations using empirical probability curves. Thus, in the current regulatory documents intended for the design of hydraulic structures, there are shortcomings in the methods for determining hydro meteorological characteristics which leads to a decrease in their operational reliability during the passage of dangerous rain floods. The necessity of appropriate updating of the existing regulatory documents is substantiated.
