“…Different morphometric parameters of individual species vary differently in the gradient of the same anthropogenic factor (Sukhodolskaya & Saveliev, 2014). Head width, elytra length and four morphometric indices significantly change in B. aspericolle under the influence of anthropogenic factors (Komlyk & Brygadyrenko, 2019). Changes in the linear dimensions of B. minimum body with an increase in recrea-tional load and cattle grazing are similar to those found in our researches.…”

“…Ground beetles can be divided into two groups: in some -females are more sensitive to environmental changes, in others -males. In our researches, B. minimum females are larger than males, as with B. articulatum and B. aspericolle (Brygadyrenko & Slynko, 2015;Komlyk & Brygadyrenko, 2019). Sexual dimorphism of B. minimum is in evidence in all linear parameters and most morphometric indices.…”

“…Morphometric measurements were performed using photographs in the TpsDig 2.17 program (F. James Rohlf, State University of New York at Stony Brook, USA, 2004). 13 linear characteristics, 1 angular characteristic, density of pores on the elytra, contrast of the light spots of the left and right elytra were measured (Brygadyrenko & Fedorchenko, 2008;Brygadyrenko & Korolev, 2015;Komlyk & Brygadyrenko, 2019). Six morphometric indices were calculated (Brygadyrenko & Reshetniak, 2014;Brygadyrenko & Slynko, 2015;Komlyk & Brygadyrenko, 2019).…”

“…Species of the genus Bembidion occupy most of these biotopes. We previously studied the morphological variability of three species of the genus Bembidion: B. varium (Olivier, 1795), B. articulatum (Panzer, 1796) and B. aspericolle (Germar, 1829) (Slinko et al, 2008;Brygadyrenko & Slynko, 2015;Komlyk & Brygadyrenko, 2019). This article is devoted to the study of the morphological variability of B. minimum (Fabricius, 1792), which is widely distributed in riparian biotopes.…”

Morphological variability is the result of interaction between genetic diversity of the population and environmental selection. Despite the large number of studies of morphological variability of ground beetles, there is very little research dedicated to influence of environmental factors on it. This article discusses the influence of natural and anthropogenic factors on the variability of Bembidion minimum (Fabricius, 1792). B. minimum is a West Palearctic species which is distributed in North Africa, Europe, Western Asia. It is a macropterous species that lives in humid biotopes along the shores of seas, rivers and standing water bodies. 410 specimens were collected from 12 ecosystems differing by plant cover, degree of litter development, mechanical composition of the soil, mineralization and acidity of soil solution, type and intensity of anthropogenic impact. 13 linear characteristics, one angular characteristic, density of elytra puncturing and contrast of spots on the beetles’ elytra were measured. Additionally 6 morphometric indices were calculated. More than a third of the variability of imagoes in the studied populations was found to be determined by the general body size. Sexual dimorphism was observed on all linear parameters and most morphometric indices. Females do not differ from males in the back angles of the prothorax. Natural and anthropogenic factors to a greater or lesser degree were shown to affect the morphological variability of B. minimum: soil acidity and mineralization have the greatest impact. The soil acidity causes significant variability of most linear parameters; mineralization – body length, head length, prothorax length and width, elytra width. Plant cover and mechanical composition of the soil have a slight impact on imago morphology. The type and structure of vegetation significantly affect head width, prothorax length and width, and the mechanical composition of the soil – body length and head length. Degree of litter development does not cause significant changes in the linear dimensions of beetles. With thickening of the litter the posterior spots on the elytra become brighter, they have sharper contours, and density of elytra puncturing also changes. The mean value of the back angles is affected by the herb layer of meadow vegetation, soil mineralization and acidity. The variability of morphometric indexes under the influence of natural factors was found to be lower than variability of linear characteristics. The recreational load and cattle grazing cause similar changes in linear measurements and morphometric indexes of B. minimum. With escalation of these factors, the body length, length and width of elytra of both females and males decrease. Assessing the natural morphological variability of populations in ecosystems whose environmental factors are within extreme and sub-extreme values for a given population is a promising direction of research in modern ecology.

Dnipropetrovsk Region is situated in the steppe zone of Ukraine, in conditions of insufficient moisture. Forest vegetation covers only 5.1% of the region. Over 80% of the region’s area is used for agricultural purposes.

The analytical review attempts to summarize the results of numerous scientific research conducted by scientists around the world on selenium scattering and accumulation in natural environment, with considerable attention paid to the concentration of this trace element in soils, natural waters and plants. It is shown that selenium content in agricultural products is caused by the processes of physico-chemical and biogenic migration of this element in the biogeochemical food chain. According to the modern classification of trace elements, which is based on their biological significance for living organisms, selenium belongs to the vital group or biogenic elements. As a biotic element, it has unique physicochemical and biochemical properties and with adequately absorbed into the human body has a positive effect on a number of physiological processes. Various research shows that the majority of the world population (except in some regions) today consumes less selenium with the food than necessary and its consumption decreases every year. Insufficient selenium intake in the human body (less than 15–30 μg/day) leads to the development one of the hypomicroelementosis – hyposelenosis. Selenium deficiency is considered as a possible etiological factor in some cardiovascular, cancer, osteoarticular and neurodegenerative diseases that threaten to human life. Providing the human body with selenium in optimal amounts is one of the important conditions of nutrition. A number of countries have developed recommended selenium intake standards for the adults, which range from 55 to 120 μg/day. We can calculate the physiological need for selenium in children and adolescents by extrapolation. The most safe and effective way to maintain the necessary level of selenium for the human body can be achieved only through the poultry and livestock products by mandatory introduction of premixes containing highly effective biologically available selenium forms into animal feed. This will ensure a relatively high level of trace element in meat, eggs, and milk and would eliminate the cases of toxicosis in human population due to buffer effect of animal tissues.
