Description
The problem of environmental contamination by heavy metals is significant problem of urbanization. The search of ways of indication heavy metals pollution becomes actual, because of their simplicity and affordability. A widely used test objects for heavy metals pollution indicators are leafy mosses used for bioindication, because they are highly sensitive to any stress factor. The research shows that bioindication with using leafy mosses as test objects is highly effective method definition of heavy metals pollution. Using of bioindication methods are promising techniques for the assessment of the contamination of ecosystems by heavy metals. Through the use of this method, it is possible indication of pollution of the surface layer of air with heavy metals. The epiphytic moss (Pylaisia polyantha) growing in different zones of the city of Rostov-on-Don, was used for the heavy metals pollution biomonitoring of urbosystems. The accumulation features of heavy metals in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. pylaisiella moss (P. polyantha) accumulates the largest amounts of the following heavy metals: Zn, Cr, Pb, Sr, Ni (Kc to 1.07), and Cu. According to the Kc values, all the studied elements accumulated by pylaisiella moss form the following series of biological uptake: Zn > Pb > Sr > Cr > V > Ni > Cu > Cо. The results of investigation showed that the epiphytic moss (Pylaisia polyantha) can be used as indicator of heavy metals pollution in different polluted zones

Description
The article shows the direct impact of oil pollution on morphometric parameters and external a large burdock broadleaf and camel spines ordinary. The object of the study is Sokolovsky oil wells in the Astrakhan region. Vegetation is very sensitive to violations environment and most visually reflects the changing ecological situation territory as a result of anthropogenic impact. Petroleum products concentration of 8100 mg / kg leads to a decrease some morphometric indicators plants and deterioration of their external condition. The results of content research oil products in the soil showed that the maximum values of this indicator at the end of the oil wells (near rescue station), which was more than 8 ODK, the minimum - in control, in the region beach (0.1 ODK), at all other points. The indices were within the norm (1000 mg / kg). In the location of the oil there were 10 terrestrial plant species. We have studied plant territories using the following parameters: root length, thickness, the length of the above-ground part

ANALYSIS OF SYNANTHROPIC FLORA OF RICE SYSTEMS OF THE KRASNODAR REGION
DescriptionThis article has given the analysis of systematic and ecological structures of synanthropic flora of rice sys-tems of the Krasnodar region. There was shown the relation of plants of aboriginal and adventive frac-tions of flora to different ecological factors. There were studied the timeness of different plant species to elements of the rice system and the degree dependence of their distribution on rice growing tech-nology

Analysis of polymorphism of lagenaria fruits have been made on the basis of images of the paintings and sculpture, marked characteristic features of each country. Issues of selection on the basis of the trait of fruit form have considered

ANALYSIS OF TREE HIGHT GROWTH CURVE DEVIATION OF SCOTS PINE IN MINUSINSK PINE WOODS
DescriptionA deviation from tree height growth trends of Scots pine is analyzed. They have a periodicity and vary both by the amplitude and period. At average the value of period is 40-50 years and has a significant variabil-ity. It depends on longevity of tree life and age classes. The deviation depends on relation between the trees in stand. An abiotic factors effect increases and comes to the fore under constant of actual adverse environment conditions for growing

ANALYZE OF THE LIVING FORM OF CARABIDAE’S IMAGO IN TERSKO-KUMSCKAY LOWLAND OF DAGESTAN
DescriptionThe results of the morpho-ecological adaptations of imago carabidae researches in Tersko-Kumsckay lowland of Dagestan are exposed in this article. The species composition of carabidae in area was classified according to the Sharova’s system of living form and the detailed analyze has been done in this work

Description
In the process of the research we had accomplished an analysis of allelic polymorphism of self-incompatibility in pears in demand in the production and breeding of modern varieties of pears of North-Caucasian Zonal Research Institute of Horticulture and Viticulture collection of genetic resources. In the first stage the consensus primers PycomC1F and PycomC5R were used. With obtained data, after identification of the alleles studied in varieties using consensus primers an allele specific S5 and S8 DNA markers were used for confirming the presence / absence of data allele studied cultivars

Description
Application of a factorial method for determining the needs in metabolic protein and essential amino acids, helps to deepen knowledge on physiology of protein and amino acid supply and allow to improve the standards for dairy cows during the transition period; in insufficient of metabolic protein and essential amino acids increased coefficients of their transformation into net protein and absorptive amino acids as a result of mobilization of body of cows; with an optimal protein nutrition their transformation in net milk protein, lysine and methionine accordingly amounted to 0.67, 0,83 and 0,82. The most significant changes in the concentration of methionine, proline, glutamate, glutamine, glycine were observed in cows before calving and immediately after birth, stabilization of their level starts with a 24 lactation day, that is connected with the peculiarities of the feeding behavior of the cows and the gradual intensification of the processes of metabolism and milk production. To control the status of protein metabolism we have offered benchmarks compositions of free amino acids in cows’ blood plasma phases: 21-0 days before calving, 0-21 and 22-120 days after calving
