Classification of species being a part of zoocenosis is presented. The paper stated on the necessity of permanent realization of certain human activity for the most animal species conservation in the steppe. The specific form of activity, which forming the environment, must be a subject of protection.

Springtail populations in four forest biogeocenoses (one population – in the Polissya, two – in the Forest-Steppe, one artificial – in the Steppe) have been studied. Similar nature in seasonal dynamics of springtail populations and general tendencies of changing correlations of life forms during different seasons have been ascertained.

This article is devoted to investigation of preservation conditions of the different form of complex entomopathogenic preparation on the basis of Bacillus thuringiensis and Beauveria bassiana. It was shown, the qualitative preservation of the liquid form with 5 % NaCl, and the paste form with саrboxymetilcellulose, tiaurea, and mineral salt (CuSO4, MgSO4, ZnSO4, KCl) was got. The effective application of a bentonit as a basis for the granulose form of the preparation was provided. The efficiency of the preparation (solution with 0,5–1,0 % concentration) against larvae of Archips podana Scop. was shown.

Dynamics of competitive interactions in populations of annual euhalophyte S. europaea was investigated. For S. europaea the hypothesis of Newman and Tilman is confirmed, concerning presence of intensive competition between plants on unproductive habitats for soil resources. Vital state of plants in populations of S. europaea is determined by intensity of competitive interactions, level of humidity and degree of salinity of ecotype. On an example of S. europaea, productive activity of plants on salted habitats was analyzed and the role of interspecific competition in this process was determined.

The species and taxonomy diversity are the impotant components of ecological diversity of living organism’s complexes. The article analyses the modern approaches of quantitative estimation of the ecosystem diversity. In hypothetical experiment the indexes have been tested to study the properties dealing with taxonomy complexity reflection. Diversity indexes have been used to analyze some real soil invertebrate’s complexes.

In researches, conducted on cats after delabyrinthation, was ascertained a decrease of weakening action of Strychninum on the eariy phase of inhibition of flexor and extensor motor-neurones with a maximum of display on 3-6 ms and duration of 7-10 ms as compared was observed in conditions of conservation of labyrinthes. The late phase of the inhibition with a maximum on 30-80 ms and duration of 100-200 ms amplified. Possible physiological mechanisms of the registered phenomena are discussed.

The dynamics of total proteins content in the different phenophasis in leaves and spouts of Spiraea L. rase plant-introducent has been studied. It is noted, that the protein accumulation depends on extermal environment conditions and plants certain bind of this rase.

Research of changes of cord dorsum potentials (CDP) of spinal cord (SC) of depending on age in cats. Is shown, that the first negative component of CDP is most stable on amplitude and dynamic characteristic for all age-group. Components of CDP, which were connected to work of polysynaptic neurones and especially with presynaptic inhibition showed large variables and instability at a repeated or long-term stimulation for very young or old animals. We assume, that the specified character of changes of potentials is connected to change of an effective performance of neurones in a brain

This work directs data about mineral water genesis. The accent on balneological sense is done. We suggest the criteria of biochemical processes estimation which take part in mineral water compounds creation. These criteria can be used for illustration of dependence between waters medical properties and biochemical processes of their genesis.

The genetic connection of animal complexes and soil cover is in the basis of diagnostic ability of animals to indicate and quantity assessment of soil processes. The ecoiGgical view and peculiarity of soil animal complexes has the most impotent value. The soil animal complexes of steppe and their trans-formation under artificial forest are discussed

Catalase and peroxidase activity dynamic in ripe corn of different ripeness term maise hybrides on sowing term and grow regulator influence was studied. Term sowing and seeds incrustation influence on these ensymes activity depedence was discovered. The possibility of optimum sowing term selection and grow regulators using for adaptive plant systems condition influences were discussed.

The influence of benzene physiological and biochemical indexes of four species of tailless amphibians was analysed. Decrease of relative weight of amphibians organs and tissues was found. This can result in the declin animals resistance to toxicants influence and to degradation of their populations under conditions of influence chemical enterprises sewage.

Antioxidative enzyme superoxide dismutase (SOD) role in maize grain was investigated under herbicide action. Combinations of Dialen C with Harness, Primextra Gold and Frontier were used. Increasing in SOD activity proved to be a highly sensitive reaction. Data obtained suggest an enzyme participation in homeostasis supporting in stress conditions.

The development and the structure of the ovule and the embryo sac of the representative of the family Hydrangeaceae Deutzia scarba are investigated. It is established that the ovule of the given species is hemitropic, tenuinucellatic, unitegmic. The embryo sac develops according to Polygonum-type. The structure of the mature ovule has the specific peculiarities connected with the growth of the micropilar region of the embryo sac.

Experimental data on chronic influence of ions of heavy metals in a dose of 2 EPC (extreme permissible concentrations) and of low-intensity irradiation in a dose of 0,25 Gr both separately, and jointly on transmembrane transport of K+ ions through membranes of rat brain cortex are submitted. The decrease of passive and active flows of potassium ions under the effect of irradiation has been shown, that, probably, is connected to disturbance of membrane transport functions. Under the combined influence of a mixture of heavy metal salts and of irradiation increase of passive permeability of K4 has been observed simultaneously with inhibition of active membranous transport, that can testify to exhaustion of compensatory capabilities of a cell on a background of structural-functional disturbances of a membrane

The dynamic of changes of capacity of electroencephalogram’s rhythms back hypothalamus at animals of control group and group in stress conditions in parallel with rats who on a background of stress development accepted pyroxan is analyzed. The submitted results have shown influence of a pharmacological preparation pyroxan on bioelectric activity of back hypothalamus in stress conditions that restoration of electric activity under action of this preparation was more shown at 3 weeks of its application.

The new researches in optimisation of nutrient medium for cultivation of yeasts Saccharomyces cerevisiae is discussed in this abstract. Microdoses of a pancreatic RNA-ase préparation or RNA-ase of Bacillus intermedius stimulate the yeasts growth and improve their quality. Using geothermal water as the mineral sourse, ensures recovery of biomass with high biotechnological properties.
