Crimean Orchids: pollinators composition, pollination systems diversity and its effectiveness
It was given a list of pollinators of 20 Crimean species of orchids including 98 insect species. Nectar attraction is used by 6 orchid species, and 14 species are nectar-less, they attract pollinators by fraud. Within fraudulently attraction the most widespread mechanism is attraction of inexperienced pollinators by the inflorescences glow combined with mimicry with forage plant flowers of pollinators (5 species) and clean attraction of inexperienced pollinators by the inflorescences glow (4 species). Mechanism of attraction only by mimicry with forage plant flowers of pollinators is used by 2 species; mechanism of sexual attraction is used by 2 species too; 1 species attract pollinators by imitation the feed of animal origin. The major part of species under study is pollinated by bees (14 species); 3 species are pollinated by butterflies and moths, 2 species – by vespoid wasps and 1 species – by gnats. The greatest and the most stable pollination level peculiar to nectar species and species which attract pollinators by the inflorescences glow combined with mimicry with forage plant flowers of pollinators. The less pollination level peculiar to species which use clean attraction of inexperienced pollinators by the inflorescences glow.

Analysis of evoked EEG-potentials under emotionally aversive arousal condition: temporal and topographic characteristics
Influence of emotionally negative visual stimuli on the temporal and topographic characteristics of evoked EEG-potentials was investigated. It’s shown that N1, Р2, N2 and Р3 components under emotionally aversive condition appear with noticeably shoter latency than under emotionally neutral condition. Latency decrease was a maximum in the frontal, central and temporal areas of the left hemisphere.
Interactions in coenopopulations of Salicornia perennans Willd.: competition vs. facilitation
The main factor, influencing on vitality and growth of S. perennans, is humidity of soil. An intraspecific competition reduces vitality of plants, influences on the form of growth and development. In the system of biotic factors the competition is the dominant form of interactions in coenopopulations of S. perennans on inland saline habitats; facilitation is possible only on the early stages of vegetation.

The Correlation between resting state EEG-characteristics and human working efficiency
The aim of the work was to find the human rest EEG-characteristics, which can enable us to make assumptions about the efficiency and the features of further adaptation to various types of the cognition activity. Our findings suggest that results of both mnemonic and sensomotor tasks depends on the 9,5-10,5 Hz EEG-band power in the left frontal cortex at the previous human resting state.
Studying effectiveness of gas mixtures in recovering the exterior breathing functions
In order to reveal the most effective gas mixtures for recovering functions of exterior breathing after strenuous muscles activity, hyper-oxygen (34% O2) and hyper-oxygen (1% CO2 + 34% O2) gas mixtures were applied. It was revealed that it is more effective to apply a gas mixture containing higher percentage of carbonic acid gas, than to use gas mixture containing oxygen alone, as it leads not only to liquidation of the oxygen debt, but also to metabolic carbon dioxide accumulation in tissues, that in its turn speeds up the process of recovery of exterior breathing and of the whole body. Inhaling the gas mixture containing 1% CO2 + 34% O2 for a short time can be used during training process and competitions for quick normalization of exterior breathing functions and basic oxygen blood conditions as a means of rapid recovery.

Optimization of nutrient medium for the induction calusogenesis in culture in vitro vegetative organs of Clematis vitalba
Callus induction in the culture of the vegetative organs of Clematis vitalba on the modified nutrient media Gamborg-Eveleigh (B5) and the Lin-Stabа supplemented 2,4-D and BAP were investigated. It was found that the frequency of callus induction depended on the concentration and ratio of growth regulators in the nutrient medium. The highest frequency of callus induction (97%) detected during cultivation of explants on a modified nutrient medium Gamborg-Eveleigh (B5) containing 1,5 mg/l 2,4-D and BAP.

The statistical analysis of morphometric parameters of reproductive structures of wild Crimea’s orchids
The results of statistical analysis of ovary’s morphometric parameters (length, width) of 4 orchid’s species of Crimea’s flora are represented. It is shown the high variability of the linear parameters of ovaries. Revealed reliable statistical indicators, which can be criteria for assessing the species at some stage of development of fruits and seeds.
The modifications of spectral power EEG rhythms of animal after realization alpha/teta session
The alpha/teta neurofeedback sessions on two wakeful cats were carried out based on elaborated sheme. The signal of feedback was the level of audio signal given to an animal, which diminished when the relation of powers of alpha - and teta-rhythms recorded in occipital area is increased. It is revealed, that spectral power of alpha-rhythm in occipital lead is increased and spectral power of teta-rhythm in occipital and right temporal leads is decreased after EEG biofeedback sessions
