Ecological niche acts as an important evolutionary function of living organisms in the ecosystem and determines its properties, which are caused by the nutrient requirements, mobility, ability to reproduction, biochemical features, structural features limits tolerance to environmental conditions, opportunities performing certain actions in the specific biocenosis; in the process of divergence (species, their internal and external properties and abiotic characteristics) features of ecological niches are changed , there are new kinds of living organisms and, of course, the formation of new ecological niches
On the basis of the analysis of documentary data of Open Company «Tuimsky factory of nonferrous metals processing», the degree of the conformity of spent actions to requirements of preservation of the environment is established
The results of studying the ordinary pine condition in geographical cultures of the Central forest-steppe are cited in the article. The general pattern of the ordinary pine intraspecific variability is represented. The data of origin influence on safety, efficiency, qualitative adjectives is presented. The pattern of ecotypes adaptability to new environment conditions is presented
The article considers the results of engineering-ecological solutions and arrangements worked out at the diamond mining enterprise for protection of surface waters and recovery of commercial fish species resources
A method of obtaining insertion mutants for the hoc
gene, which encodes for the main phage antigen, was
developed on the model of bacteriophage T4. This gene
was cloned in the plasmid pBSL0+ and was disrupted
by insertion of foreign DNA. The phage mutants were
obtained by in vivo phage-plasmid recombination. The
construction of insertion bacteriophage mutants was
carried out in two stages. The resulting mutants on this
procedure could be grown on wild-type E. coli strains,
which is convenient for the production and use of these
phages in therapy. The mutants obtained had reduced
antigenicity. At the same time, the yield of the mutant
strains was high when they were grown on the
non-suppressor E. coli laboratory strains. A number of
stages of purification of the bacteriophage mutants
obtained were performed. Preparations have been
studied by transmission electron microscopy and mass
spectrometry. By several periodic cultivations of the
mutant bacteriophages, it was shown that mutations of
this type are stably maintained during more than 50
generations. T4 related bacteriophages of the family
Myoviridae, for example, T-even, have the significant
homology amongst their genomes, which makes
possible to produce similar mutants. Thus, our method
was developed to obtain mutants with reduced
antigenicity which can be used for both the treatment of
systemic infections, and diarrhea in the case, when,
bacteriophages penetrate into the bloodstream. Such
phages can be used in medicine and veterinary. The
reported study was partially supported by RFBR,
research projects No. 13-04-00991, 16-44-230855
The article covers the Akabane disease agent identification in the new green monkey kidney continuous cell line (VERO) that has not been used for that in Russia before. Besides, the time for the virus detection using the fluorescent antibody method was found to be considerable decreased
In this article we consider application of the automated systemic and cognitive analysis (ASK-analysis), its mathematical model – a systemic information theory and the program tools realizing them – the intellectual Eidos system, for input (digitization) of images from graphic files, synthesis of the generalized images of classes, their abstraction, classification of the generalized images of classes (clusters and constructs), comparison of concrete images with the generalized images (identification) of classes, comparisons of classes with each other and creations of the generalized images of genus of ground beetles on the basis of images of the types. The new approach to digitization of images of ground beetles based on use of a polar frame, the center of weight of the image and its external contour is offered. Before digitization of images, their transformations standardizing the provision of images, their sizes and an angle of rotation can be applied. Therefore, the results of digitization and the ASK-analysis of images can be invariant (are independent) concerning their situation, the sizes and turn. There is a successful experience of the solution of similar tasks in other subject domains. This article can be considered as a continuation of series of the works devoted to application of the automated systemic and cognitive analysis (ASK-analysis) and its program tools – the Eidos system
The Mavrostifo – Greece aboriginal variety. It is belong to the group of varieties convar. pontica subconvar. balcanica Negr. The time of production period is 156-165 days. The variety of medium height. The degree of ripening of vine is higher.

The article considers data on the stocktaking of plants
in the collection of medicinal plants of the Yakut
Botanical Garden on the following parameters: the
study of the component composition, the inclusion in
the Pharmacopoeia articles and the Russian State
Register of medicinal products. Introduction test in the
collection has been performed for 158 species from 99
genera and 41 families, currently the collection has
101 species from 79 genera and 34 families. Chemical
composition of plants is known for 61 species. 17
species are pharmacopoeal and 15 species make
medicinal products available. The rest of the medicinal
plants can be used in folk medicine. Most represented
are Asteraceae family (25), Ranunculaceae (20),
Rosaceae (16), Fabaceae (15), Lamiaceae (13), among
tested plants. According to the assessment of
introduction capabilities, 49 species in the collection
are highly stable, 51 - stable and just one is unstable
Currently, when solving the problem of greening it is
addressed to the technical and technological capabilities. These means can achieve some improvement of the environment in a particular region, but they are not enough to solve the problem of pollution in the whole country and the world. The
problem in general can be solved only through an integrated analysis of the set of economic and ecological processes, which makes it possible not only to improve the development, but also to manage the process of impacts on the environment itself
