Total ecosystem respiration and evapotranspiration of steppe catena (West Siberia) The article deals with the diurnal dynamics of CO2 emission and evapotranspiration of steppe ecosystems. The profiles of carbon dioxide distribution in soil atmosphere were set under soil salinity conditions. The findings help to explain the ecological function of steppe catena.

Features of action of weak low-frequency alternating magnetic field on the intensity of division planarian Dugesia tigrina at static magnetic field with "zero" and geomagnetic values It have been shown that exposure of the planarians to low-frequency alternating magnetic field (frequency of 3,7 Hz, the amplitude of 40 nT, exposure 4 h) in combination with a static magnetic field collinear with the induction of 42 mT promoted its division. On other hand compensation of the static magnetic field (induction £ 0,1 mT) by means of alternating magnetic field resulted in the opposite directional inhibitory effect consisted of reduction of the number of divisions of planarians.

Dynamics of toxicity waters of the small river within megapolis (r. Temernik, SFD) Ecological problems of small rivers were considered. Based on years of material toxicity waters r. Temernik (SFD) at bioassay was shown the evolution of toxicity classes and ecological status of water.

Erosion processes on the territory of small catchment — regularities of formation Analysis of the results four years of research of the snowmelt runoff formation and soil loss on the catchment area of the small river Lubozikha showed that surface runoff and soil washout has an influence not only on the intensity of erosion processes, but also on the chemical composition of river waters.

To the study of water mites (Acariformes) as part of a small river Devitsa Zooperiphiton (Voronezh region) An ecologo-faunistic information about 13 species from 6 families of water mites of zooperiphyton  river Devitsa (Limestone North Central Russian upland, Voronezh region), of which 10 are listed for the first time for the region. Identified dominant and rare species, preferences in of various substrates.

Effects of partial cutting on soil microbial complex in pinewoods of Krasnoyarsk forest-steppe region The analysis of a structural-functional condition of soil microbita has shown, that satisfactory soil forest-vegetation conditions the pinewoods density of 0,6—0,7 which have been passed by the first cutting. Intensity of felling a forest stand, the season of lumbering and a way of brush disposal the promote redistribution in structure of eco-trophic groups of microorganisms and formation of an optimum level of enzymes activity in soil.

The role of agrochemistry in the conditions of modern agriculture in Russia An analysis of current problems and the negative consequences of underestimating major laws of agriculture in the Russia were carried out. Have considered the ecological function of agrochemistry in agroecosystems and the conditions which necessary for the successful development and modernization of  agriculture of the country.

The soil and microbiological characteristics of virgin and deposit gray forest soils of Priangarye, are formed in conditions of hillocky relief One of the factors that determine the characteristics of soil formation and soil microbial processes in the Priangarye is hillocky relief. It promotes differentiation of soil-forming processes in the soil profile and a sharp difference of their morphology and properties. When plowing of soil is a significant change in the properties of soils [12] and microbiological parameters [13], which for a long time is saved when translated into deposit mode.

Introduction of trees and shrubs in the Nikita Botanical Gardens and their naturalization on the Crimean peninsula The check-list of trees and shrubs presented in collection of the Nikita Botanical Gardens capable for self-reproduction or run wild on the territory of Crimean peninsula have been provided. Invasive activity of species have been given according to the categories used in the database on naturalized species in European botanical gardens.

Agroecological efficiency of use of rice meliorative cultivated lands on the basis of the evaluation of agricultural resource territory potential The approbation of methodological approaches according to the agroecological evaluation of lands of rice irrigation system has been conducted. Based on the analysis of statistic and predicted data on yield capacity of rice crop rotation it has been proved that it can be eligible for developing farming system in rice cultivation. The correspondence between actual and calculated according to the degree method of agroecological land quality has been discovered.

Some peculiarities of reproductive system of the campanula sibirica l. (campanulaceae) The results of biology study Campanula sibirica L. at the conditions of his nature growth at the mountain Crimea have been presented. Peculiarities of the male and female reproductive structures development (availability of the placentoid and the fibrous thickening in the walls of the connective cells in microsporangium, development postamento-podium and hypostases in ovule etc.) have been shown. The of flowering and pollination processes have been described in details; the phenomenon of the invagination, the male phase in the flower  bud, structure of seeds, and also the mechanism of dissemination have been illustrated.  The conclusion about the formation many quantity of seeds and possibility their dissemination at greatly distance has been determinated of the original peculiarities of flowering, pollination and also the structure fruits and the  dissemination of this species  has been made.

Lunaria rediviva L. (Cruciferae) from Mordovian State Nature Reserve in Conditions in vivo and in vitro Perennial honesty is the tertiary relict of European deciduous forests. In the Republic of Mordovia it known from the Mordovian State Nature Reserve and the National Park «Smolny» and it is included in the regional Red Data Book. Population of Lunaria rediviva L. from the Mordovian State Nature Reserve was studied. The composition of the accompanying flora is revealed and it is analyzed on the environment factors. Comparison of the ratio of age groups and generative elements of individuals in the population for 2011—2012 was carried out. The attempt to reduce the stratification period of Lunaria rediviva seed in its germination in culture in vitro by exposure to sterilants was made.

The kind of adventitious flora in the Kaliningrad city 201 kind considered adventives plant growing in the Kaliningrad city. The analysis of adventives species.
