The article demonstrates the taxation parameters of the pine plantations that was damaged by fire in 2010 in Suburban forestry of the Voronezh region and was calculated the basic ecological functions they performed before death. The intercommunication was found between increasing level of air pollution in the study areas and growing of heart and pulmonary morbidity of population
Development of plants in mixed or combined sowings is based on the symbiotic association in the basis of which we have decreased sexual process and its mechanism of genetic exchange among endosymbionts and stimulating of genetic exchange and expansion of the diversity of species among exosymbionts. The exception is the symbiosis of orchids and fungi - activators of orchids mycorrhiza with developed micellar system easily passing on saprophytic option. Coevolution of plant organisms with fungi indicates the specifics symbiogenic conjugate evolution, showing an example of the evolution of a small community with different contact with the external environment. The phenomenon of symbiogenesis has a long history and was manifested in a variety of different types of organisms. Today, some dependence of existence of one species from other organisms is observed at approximately 75% of higher plants and 90% of the animals in varying degrees of symbiogenic dependence from other species and taxa. Originality of symbiogenesis was analyzed by Academician A.A. Takhtadzhyan (1973) during its consideration of origin of eukaryotic cells as process of "assembly" of a complex system. Different approaches to determining the biological essence of symbiosis are known in the history of study of this phenomenon. On the whole phenomenon of symbiosis belongs to the category mutual relations of organisms of different phylogenetic groups
Creation of joint sowings is very complicated modern environmental problem and the solution is impossible without a comprehensive study of the relationship between individuals of different species that are emerging at the level of a plant community. Studying biotic relationships between taxa used in these crops is very important; joint crops include combinations (sowing crops in rows) and mixed crops (crop seeds mixed and sown together); great attention in the mixed and combined sowings has been paid to selection and combination of cultures
The main criteria in assessing the adaptive capacity of Actinidia deliciosa (kiwi), cultivated in Russian subtropics were yield of the introduced cultivars, as well as ecological (stability and periodicity of fruiting) and biological indicators (resistance and periodicity of fruiting). The studied nature of the way Actinidia cultivars react to the constantly changing weather conditions during the period from 1998 to 2011 will help to optimize the placement of the crop in subtropical zone, and use natural resources for its unique climatic properties of Russian territory in a sustainable way
The condition of agrolandscape systems of Kuban has limited number of natural factors, among which an important place is occupied by temperature, moisture, nutrients and places with weediness of sown areas. Basic soils are occupied by cultivation of agricultural crops with a significant presence of segetal communities in the tilled crops, as well as field protective strips. In soils of agricultural landscapes there are actively developing bacteria, actinomycetes and microscopic fungi, the representatives of mesofauna, qualitative composition of which is very varied. When characterizing the soils we can mark a broad aspect of their contamination with heavy metals and oil, as well we pay attention to peculiarities of agriculture
The article studies the problems of correlation of protection of environment and provision of environmental security including the problem of organizational mechanism of protection of environment in the process of ensuring environmental security
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
The article presents the data about flora and vegetation of
the territory of the Yakut Botanical garden, where an
ecological trail will be; there is a characteristic of plant
communities and their classification. Preliminary, the
flora of the ecological path includes 310 species of
higher vascular plants belonging to 54 families and 172
genera
The article presents the ecological characteristics of soil types and forest cover of the Red October forestry of the State Unitary Enterprise of the Republic of Adygea. We have defined their relationship and the division into groups of forestry and environmental values. A complex combination of bioclimatic factors, parent rocks and topography has led to a large diversity of soil cover. We have revealed that different soils have different degrees of erosion on sloping hillsides, ravines, and steep slopes are dominated by strongly eroded soils. The most common form of physical degradation of soils of the red October experienced forestry is seal root layer observed on heavily used areas and pastures. Also, we found that poorly structured soils containing little humus are prone to compaction. Methods of rooting out areas after clear cutting of forests lead to secondary soil degradation. It especially enhanced if, at the moment of stressing, the soil is in the waterlogged condition. Therefore, at reforestation we should use different reclamation processing. And this leads to the difficulty of their use in reforestation. It is established that intensive anthropogenic activity leads to degradation of soil and forest cover of the study area
A significant decrease in yields of field crops due to lack of moisture enhances the role of adaptive breeding. The development of varieties that combine high productivity and quality and resistance to biotic and abiotic stresses is complicated by a negative correlation between high yield and resistance to adverse conditions. Selection of effective methods for assessing the potential of productivity and resistance to stress factors allows creating varieties that provide stable high yields. We had estimated six varieties of common mustard for 10 years in contrasting weather conditions in the zone of insufficient and unstable moisture of the Azov district in the Rostov region. The necessity of taking into account the indicators of the HTC, the index of the environment and its value when conducting an objective analysis of weather conditions is revealed. The greatest stress resistance, ecological plasticity and stability of the Nika variety were established by calculating the difference between the minimum and maximum yield per year, calculating the coefficient of linear regression and the value of homeostasis. The varieties Lera, Donskaya 8, Lux bred in conditions of insufficient moisture demonstrated maximum genetic flexibility and drought resistance. The greatest breeding value was determined in varieties Donskaya 8 and Lera. These varieties are recommended to be included in further breeding work. The study of mustard varieties in contrast conditions (HTC from 0.30 to 1.53) marked their broad environmental plasticity, which makes it possible to recommend them for cultivation in different weather conditions regions
