The role of septum in the mechanisms of aggressive behaviour formation has been studied. It has been established, that forced stimulation of septum leads to diminution of aggressive manifestations in behaviour. Electrical destructions lead to outburst of strong aggression in behaviour. Behaviour is accompanied by a considerable increase of convulsive paroxysmal activity. Monoamines are neurochemical substances ensuring this behaviour. They form complicated hierarchical interrelations between each other.

The methods and a laboratory bench have been developed for research of the multienzyme systems of cyanobacteriae Mycrocystis aeruginosa. The bench allows regulating the luminous intensity and suspension agitation, studying the cells reproduction and conducting the chemical analysis of water. It has been established that algae can be used in a biofilter for reducing low concentrations of total iron in water to the levels which meet state standard (GOST 2874-82) requirements. Algae cells reproduction during water treatment from iron in a biofilter indicates that the number of enzyme systems and their activity increase. The advantage of the algae multienzyme systems use for the water treatment is the fact that they maintain their activity for a long time and do not need any carbonaceous energy substrata.

The influence of the fishing electrical trawl ELU-4M on ichthyofauna in artificial ponds is studied. The comparative analysis of the results obtained and the literature sources is presented. Negative and positive consequences of the electrical trawl application for industrial fishery and regulation of its use are described. It is determined that the exploitation of the industrial electrical trowl (taking into account some ambiguous influence to the biota) in artificial isolated ponds doesn`t influence catastrophically on a hydroecosystem. The work regulation of trowl consists in limitation of its seasonable and diurnal uset, and also in the fishing locations.

Experimental investigation of defensive behavior of Rasbora paviei Tirant, 1885 from riverine and limnetic habitats was carried out. Fish for the experiment were caught in the upper stream of Cai river and shallow littoral of Cam Lam reservoir of Khanh Hoa province of Central Vietnam. Billfish Lepisosteus sp. was used as a model predator for the experiment. Distinctions in defensive reaction of R. paviei from different ecological conditions were found. It was revealed that defensive behavior of fish from river’s upper stream was more effective than that of fish from the shallow littoral zone of the reservoir.

Taxonomical composition and ecological structure of Oribatei associates in recultivated territories located near Zhovti Vody town are investigated. The artificial arboreal planting causes increase of oribatida number in comparison with recultivated areas without arbors. Planting of trees and presence of the leaf litter promote to redistribution of oribatida life-form and change of structure in their complexes. The positive influence of artificial forest ecosystems in technogenic landscapes of different stages of technical remediation on forming of Oribatei ecological structure is shown.

The direct comparative facts of different options of inoculum production of Plearotus ostreatus:classical, tissue, with the use of «grain», active and fermentative mycelium are presented. The advantages and shortcomings of each method have been shown, that gives the possibility of chosing the most optimum variant for already formed grow conditions. The methods of mycelium production on the grain substrate and also with the use of the active material demand considerable expenditure for the equipment and absolutely sterile conditions that is very difficult to achieve. The improved technological possibilities of mycelium production by a new fermentation way promotes rationalisation and profitability, that cause reduction of product price

The results of the long term research on the number and the species composition of the phyllosphere’s yeasts (epigenous yeasts) of the plants in the northern, southern and subtropical regions of the Republic of Azerbaijan have been generalized. The obtained results show that the number and diversity of the yeast communities naturally decrease in different substrates, which correspond to different stages of the plants development. A set of dominant species is characteristic for each stage of the development. High yeast diversity is peculiar to forest biogeocenos rather than other ones. We identified 48 types of yeasts in phyllosphere and associated substances, 35 of which we were able to identify by morphological and physiological characteristics. Most of the identified yeasts were minor species, whose occurrence did not exceed 0.5% of the total specified yeasts. The results show that only 25 species of yeasts are permanent habitants of phyllosphere and alltogether they account for 90 % of the total yeast population.

Gas-producing bacteria were isolated from natural media: soil and compost extracts. The properties of the obtained microorganisms cultures as destructors of organic substances were studied. Studied bacteria were cultivated in experimental semi-synthetic media with saw dust and carboxymethyl cellulose. A growth at different pH values, a dynamics of growth, an amount of utilizated sugar, a volume of released gas during cultivation were studied. Most intensive growth of gas-producing cultures has been observed in a medium with CMC and the ability to gas producing was more manifested in the bacterial culture isolaited from the compost.

Microelements accumulation features are considered in micromammals’ organism taken from different degrees transformation biogeocoenosis of Dnipropetrovs’k region. Coefficients of accumulation are defined in different organs and tissues. Accumulation of heavy metals in the micromammals’ organism in different ecosystems, with a different technogenic contamination is heterogeneous. Organs which defined as concentrators are spleen, heart and gonads. They have primary accumulation of heavy metals. Organs–deconcentrators are those which have active extraction of microelements (liver, kidneysand and intestine). Tendency to the decline of microelements accumulation intensity in animals from strongly transformed biogeocoenosis are stated. Formation of the special barriers of accumulation and excretion from organism by organs–deconcentrators testifies to making an adaptive mechanism at the level of physiology-biochemical processes and, first of all, the metabolism intensification.
