Dendroclimatic analysis of stands of radial increment of the natural forest and forest plantations of Scots pine in the Khrenovoe pine forest, growing in dry-moist site conditions is conducted. Cyclic dynamics of increment, weak expression of the low-frequency oscillation amplitude in the plantations stands is revealed. Direct correlation with precipitation has increased over the past 40 years, in complex suboron – to 0,48 – 0,50
The results of biological recultivation of disturbed lands are offered in the article. Silvicultural and taxation parameters of basic wood types of dumps and their role in stable ecosystem formation are presented
Products, received from hips (fruits of wild roses), are profit a high consumer demand, that dictate solutions, which connected with technology of improvement natural dense bushes and creating artificial planting the most valuable in economic relation forms. In connection with it different characters of allocation of wild rose’s bushes is revealed by indicator of size of hips
Simulation models are designed to reflect the cause-effect relationships between epizootic situation tensity for bovine leucosis and technogenic & radiation factors of environmental pollution. Zoning of Chelyabinsk region in terms of epizootic risk of bovine leucosis was carried out
Radioecological risks of bovine leucosis spread among cattle in Chelyabinsk region are estimated. The obtained data can be used for simulation modeling and the forecasting of leucosis prevalence in the conditions of ecological troubles
The results of primary screening of bacterial strains on the basis of cell-wall degrading enzymes and antifungal activity against the fungus Fusarium graminearum. Selected active strains perspective for the development of biopreparations based on their type of multifunctional action to protect fall wheat from Fusarium pathogens are given
Regularities of the succession of the dynamics of Durmast Oak and Pedunculate Oak Forests on the fundamental land forms of Western Caucasus have been established and studied
We have assessed the effect of the new generations of fungicides on the vital activity of daphnia. The data of the chronic experiment allowed us to determine non-effective and threshold concentrations of the substances studied. The toxic effect of the xenobiotics is shown to be of different intensity. When entering water they may be dangerous, first of all, for the zooplankton that is the food base of young fish, and may have unfavorable effects on fish development
Results of studying of meat efficiency of bull-calves of Kazakh white-headed, Kalmyk and Simmental breeds are evaluated. Features of formation of meat qualities of bull-calves in the conditions of the Bottom Volga region are considered
The article gives the estimation of the influence of Agro industrial complex on the state of small water basins. Hidrochemical and microbiological researches of rivers at their main stages of water regime were conducted. Seasonal fluctuations of main polluting substances were revealed. For microbiological estimation of the water quality in investigated water basins, there was done the calculation of the total quality of microorganisms. At the same time, a quality control of sanitary demonstrative microorganisms was done
