In the article we have investigated the influence of nickel oxide in the amount of 100, 1000 mg/kg of the soil (1, 10 MPC), combined with the influence of an alternating magnetic field of induction of 50, 100 and 650 µT power frequency of 50 Hz on the biological
properties of alkalinity black soil
The article gives an assessment of resistance of the brown typical soil of the Utrish national reserve to pollution with heavy metals (Cr, Cu, Ni, Pb) and oil on biological indicators
We have studied changes in flora, humus content, peroxidase activity and polyphenoloxidase in ordinary black soils in natural succession of different-age deposits. We have also selected stage successions in uneven deposits
This article presents an assessment of the stability of the black soil of the Crimea to contamination with heavy metals (Pb, Cu, Cr, Ni) and oil using biological indicators
This study was aimed on testing of IRAP markers developed
at plum on varieties of peach, Russian plum and cherry plum and genotyping of home and foreign varieties of plum, followed by an analysis of the data. During the testing of the markers have been identified as a high level of polymorphism between genotypes of plum and between the studied species. On the basis of the results obtained by genotyping 15 samples of Prunus was built dendrogram. Cluster analysis was divided into 3 groups corresponding varieties of P. persica, P. domestica and a common group for varieties of Russian plum and cherry plum
The optimum combination of quantitative and qualitative
relationships between structures of organic and mineral wastes of various industries provides the formation of compound composts, which improves its physical, chemical and biological properties of the soil, helps conserve macro- and micronutrients, organic
matter, enhance ecological niches system, to ensure the
development of ecological trophic groups of microorganisms
This article presents the data of chorological analysis of the flies’ fauna (Insecta, Diptera) of the Kamishanova Polyana Nature reserve. The analysis of distribution of 432 species of the reserve allowed to identify the 4 groups and 16 types of areals
The article presets results of the studies that reflect the nature of the distribution of forests of Predkamje of the Republic of Tatarstan on the types of forest grown conditions, the predominant tree species, age, site class, completeness and volume of stem wood. It is shown that there are large reserves of increasing productivity of forest stands by optimizing their density and species composition of forests
The effects of increased water temperatures on the reproductive characteristics of rainbow trout females were studied. It was found, that the increased water temperatures produced negative effects on the gonad maturation and survival of the embryos when acted at the late stages (IV and V) of female gametogenesis, but not at the earlier (III) stage
The article considers the enzymatic activity and some other ecological and biological properties of zonal soils of the Crimea (cambisol, Chromic cambisol, different subtypes of chernozems). We have revealed significant differences in catalase, dehydrogenase, polyphenol oxidase, peroxidase,
invertase for soils of the Crimea, which can not be explained only by the content of soil organic matter. Despite the low humus content of the soil, some have a high level of some enzymes. The level of enzyme activity depends on the reaction medium, the content of carbonate and other soil properties. We have also revealed that the agricultural use of brown
soils under vineyards leads to a significant change in their properties and enzymatic activity
