Matviichuk O. The specific structure of ornithocenozes of Upper and Middle Pobuzhzhia within the anthropogenic transformation of ecosystems

The existent literary sources of the problems of specific composition, character of stay, and biothopical belonging of the birds of Upper and Middle Pobuzhzhia, as physical-geographical region, were studied and generalized for the first time. The complex researches of modern specific structure and quantity of ornithopopulation of anthropogenic landscapes were conducted for the first time; quantitative correlation of kinds is given on the type of fauna origin, the composition of meal which prevails in a ration, after the place of nesting and character of stay of different types of birds on the research territory. The features of the biothopical distributing and terms of migrations were found out. The conformities with a law of forming and functioning of ornithocenozes of artificial landscapes of Upper and Middle Pobuzhzhia in the conditions of growth of the anthropogenic loading were studied. The comparison of ornithopopulation of basic types of anthropogenic landscapes of Upper and Middle Pobuzhzhia was done. On the basis of analysis of literary sources and results of own researches the reasons and character of changes in the avifauna of region during the last and the beginning of current century were found out and the ways of reduction of anthropical pressure on artificial ecosystems were offered.
