The extent of biological invasions in southern Ukraine for the vertebrates, their significance and implications forecosystems and humans were evaluated.

Peculiarities of distribution and current state of feather-grass communities of Azov Sea coastal zone are describedand the measures for their protection were proposed. Characteristics of some six syntaxons of the coastal zone weregiven. It is suggested to create five objects of Nature Reserve Fund of Ukraine for the protection of the feather-grasscommunities.

Physical and chemical regularities of coagulant treatment of sewage of Open Joint-Stock Company «GidrosylaMZTG» from heavy metals, chlorides and sulfates by with aluminum sulphate are studied.

Data on algae floristic spectrum of coastal salt marshes of the left bank of Molochny liman were presented. Thealgae diversity was presented by four compartments: Cyanophyta, Chlorophyta, Bacillariophyta, and Xanthophyta. Theregistered algae belong to 15 orders, 20 families, and 27 genera. The Cyanophyta algae were the dominant in exploredsalt marshes, counted 56% from total discovered species. The schematic algae structure of left bank salt marshes ofMolochniy liman was performed, some algae macroscopic accrescences on salt marshes surface were revealed,dominant algae families, dominant and most abundant algae species were defined.

The forming mechanism of the biological and seed productivity of halophytes of different ecological groups inUkrainian Priazov’y? was considered. Salinity in all the periods of vegetation was considerably influenced on thegrowth processes as well as biological and seed productivity of the plants. The negative action of salt stress wasextremely high in the middle of the vegetation, when other external factors have maximum effect, the plants werecharacterized by biggest sizes of surface and the important processes of pollination, impregnation, and forming ofseed are determined. The mesophytes were seemed to be the most sensible to the salinity, but the halophytes werealso depended upon this factor. The pattern of plants distribution along the salt gradient was performed: P.lanceolata ® A. santonica ® H. pedunculata ® S. europaea.

Role of river valleys in the existence of a large number of bird species is greater than in the breeding period andduring seasonal migrations and movements. Total during the year they recorded 102 bird species, including 62 speciesof breeding period. Feature of the habitat of the valleys of small rivers is the combination in small areas of differenthabitats. This increases the patchiness of zonal steppe landscape, which allows the expansion of areas along the riverbeds of individual species. Flood regime of rivers is the determining factor for the birds: The most diverse speciescomposition and abundance of avifauna of individual species in the high-water seasons.

Distribution and ecology of weevils of Larinus were investigated. In the vicinity of Zaporiz`ka oblast (Ukraine)some 9 species were found, namely Larinus adspersus, L. canescens, L. jaceae, L. minutus, L. obtusus, L. planus, L.sturnus, L. turbinatus, L. vulpes. Data on number, distribution, feeding, phenology, breeding, preimaginal developmentand parasites are given for each species. It is suggested that Larinus jaceae, L. ?btusus and L. sturnus could be used forweeds biological control.

The analysis of the main factors, which specify the spreading of colonial Laridae to the islands of Azov and BlackSea region, is presented. The influence of the anthropogenic pressure and the interspecific interrelations on the islandbird communities is considered. The basic directions of anthropogenic influence on island birds were determined. Theanalysis of mutual breeding of island birds was performed.

The results of the biochemical analysis of oil of mutant and initial (control) lines of sunflower which were differedby morphological signs were compared. The mutants with definite marker signs which have the oil with some changesin eicosanoic acids ratio were revealed.

The article devoted to the problem of conservation by means of ecologically

In recent decades the number of gray ducks within range of the species has declined sharply, it has been includedin several national Red books, including the Ukrainian one. Restoration of this species is only possible by studying ofthe features of its biology and amendments to the game hunting. The lake forest-steppe part of Western Siberia is stillthe center of the reproduction of gray duck. Reproductive capacity of this species is extremely high. The brood had upto 6-13 eggs, with an average of 8. Early clutches contain on average 9-11, late - 6 eggs. In broods there are 6-11, withan average of 8 chicks. Mixed stack with other species of ducks make up to 2,7%. The breed mortality in different yearswas up to 66,7%, the eggs - up to 20,5%, mortality of nestlings - 30,9%. To restore the population of gray duck huntingreserves it is recommended to conduct the biotechnology activities, to create special conditions for transition to colonialtype of breeding.

Landscape and biotopic characteristics of some Sivash islands are presented. The principal role of these factors forthe support of the bird species diversity is proved. It is suggested that the islands’ genesis determines the dominantvegetation and the breeding habitats for the birds. Two types of islands – accumulative and continental are considered.

The individual features of blood microcirculation were investigated for children of 6-9 years. The childrennormative of blood microcirculation were revealed due to laser Doppler flow data.

On results the long-term researches conducted in 1988-2008 the estimation of dynamics of biodiversity the nestingbirds’ community of Molochny estuary was performed. The breeding birds’ community of reeds, saline lands, sandyislands and spits, arboreal-shrub jungles were estimated. Is is proved that the gulls, terns, cormorants and passerineswere the dominant species during the period of high water. Maximum specific variety was also proved for this timeperiod. In drought seasons of 2001-2010 the water level in estuary went down sharply that had resulted in the decline ofbiodiversity and amount of breeding birds. Negative trend of biodiversity level was discussed.
