It was shown that some emergent aquatic plants may be used for treatment of waste waters. The plants have specific composition of surface lipids (SL). The SL composition was found to be changed under the influence of water pollutants. These changes concerned the processes of elongation and desaturation of the SL components. The response to contamination was specific for each species.
Dependence of suborders Strongylata and Rhabditata larvae development from the mineralization level of soil has been established. With increase of concentration of salt the period of the larvae viability decreases. The lowest larvae number was found in the Tsarychanka district of the Dnipropetrovs’k province, which is characterized by high mineralization level of the soil. The larvae of the genera Dictyocaulus Raill. et Hen., Bunostomum Raill., Haemonchus Cobb., Oesophagostomum Mol. was found in the P’yatykhatki district; Strongуloides Wedl. and Dictyocaulus Raill. – in the Shyrokovo district; Dictyocaulus Raill. – in the Dnipropetrovsk district; Dictyocaulus Raill., Haemonchus Cobb., Oesophagostomum Mol. and Chabertia Raill. et Hen. – in the Novomoskovs’k district and Haemonchus Cobb. – in theTsarychanka district.
On the basis of research of litter mesofauna in four forest biogeocenoses of the Poltava region the trophic-weight models of invertebrate communities are creating. The biomass differentiation between trophic levels, weight and taxonomic structure of the separate levels are analysed. The differentiation and similarity of the trophic-weight models of litter invertebrate communities are discussed.
The state of pollution of natural environment along the highway «Kyiv – Warsaw» is analysed. It is indicated on the variety of plants’ species and on the basic pollutant of the environment. The peculiarities of Pb distribution in the soil and Pb concentration in the vegetative organs of predominant vegetation are lighted up. Dynamics of the toxicant distribution in crops is presented. The comparative analysis of pigments’ contents in the plants’ laminas was carried out.
On the basis of dummy individual consortia of Salvia nutans L. an important component of fertilization mechanism – the dynamics of trophic relations of antophylus agents with an entomophilous angiosperm autotroph was investigated. The dominant position in species structure of fertilizers in conditionally native steppe ecosystems is occupied by relict TomaresnogelidobrogensisCar.
