The review considers a present level of knowledge
of terrestrial gastropod olfactory system. Special
attention is given to data concerning presence of
electrical coupling on different levels of terrestrial
gastropods olfactory analyzer functioning. Analysis
of available literature leads to conclusion that
further study of neural gap junctions in terrestrial
gastropods olfactory system will provide a
significant development in its structure and function
modeling
The article discusses the features of the pathogenesis of micromycetes Gibellina cerealis Pass. in vitro
This study has investigated the relationship between culture media, technique of concentrating and freeze drying conditions for the cells of Lactobacillus aci-dophilus. The study has demonstrated that milk whey tomato juice-enriched medium has the high-growth properties. This medium allows ensuring high freeze drying survival of Lactobacillus acidophilus
The results of ecological modeling of regularities of formation of vegetation sand massifs of Don basin are presented in the article
Studying the situation and the impact on mountain landscapes of Caucasus allows by means of measurements to establish the most important sources of pollution, to identify the main forms of pressure (emissions, solid wastes, etc.) on the natural landscapes and agricultural systems, to develop a monitoring program with allocation the main objectives and most important tasks of its implementation. The main purpose of monitoring – is to collection of basic information, which will be aimed at addressing specific environmental problems for improvement soil cover on northern slopes of Caucasus and protect it from water erosion. The monitoring program allows getting information, which is due specific problem and conditions of certain area. The main tasks of monitoring the soil cover of northern slopes include concrete achievements in solving problems. At the beginning of monitoring follows determine the range of issues under study. More than often limited resources strictly dictate the need to reduce of measurement program, but always save quality of received material. For solving this problem we have to define the polygons of monitoring and select the objects that are affected by anthropogenic and natural factors. Considering defined technique, it is possible to evaluate the direction of development of particular ecosystem under the influence of a specific mode of action
Surface sewer depends on vegetable cover. Deleting the
vegetable cover (due to cutting, overindulgent fall out
live-stock, fires), wrong plowing up of surfaces (along
declivity) and processing of ground without observance
agronomic rules bring reinforcement of erosions, local
soil washout, origin gully erosions and to increase the
turbidities of the rivers
The article deals with the use of paintings as illustrative and analytical material in the course of "Genetic monitoring", like sections of "Human Genetics", "Epigenetics". Using the paintings of great artists as the visual material in the learning process
performs several tasks: analytical, informational and resourcefu
We investigated the basic soil types (brown, brown wood) of foothill zone of Dagestan. We revealed that the distribution of nickel, chromium and lead in the soils depends on several factors: soil-forming rock, physical clay, humus and pH. We defined the background content of heavy metals in the studied soils of the region
The peculiarities of vegetative propagation of ornamental plant Hypericum forrestii (Hypericaceae) by cuttings under conditions of the Black Sea coast of the Krasnodar region have been studied. It has been found that summer cuttings of lignified and semi-lignified propagula are the best for vegetative propagation of Hypericum forrestii
In the article we have investigated the ontogeny and
the peculiarities of the passage of its stages from
Pulsatilla patens (L.) Mill. We have characterized the
morphological features of the developmental stages.
The age structure of populations and the influence of
anthropogenic factors on it have been set
