Lisovyy M. Ecological peculiarities of species condition of entomological biodiversity of agrolandscape in the Forest-Steppe Zone in Ukraine.

The dissertation is devoted to the theoretical grounding of key factors of precritical condition of agrosphere in Ukraine on the base of the investigation of natural dynamics condition of agrolandscape biotes. As a working hypothesis of dissertation it was created the logical module of the principal factors of modern ecological condition of agrosphere on the base of the conception of ecology-economical function of biodiversity. It was established, that at the average index of specific entomological biodiversity of agrolandscapes in the Forest - Steppe Zone in Ukraine decreased by 49,6%. The decrease of biodiversity level was accounted for insect- heophyles, in a greater degree, it reflects essential ecological disruptions of pedosphere. By the species biodiversity and plenty indexes tree belt area agrolanscape biotes are the most loaded. Against the background of species biodiversity, taxonomical structure rearrangement of entomocomplex is observing. Regularities of space-time distribution of species insect diversity index in agrolandscape represent very difficult development in the heterogeny index in the space and time either in the conditions of genetically homogeneous plants of agrocenosis, or ecological niches diversity in the conditions of ecotones of different nature and seminatural ecosystems. Due to lack of human pressure species biodiversity is gradually growing in seminatural ecosystems, it contributes in long-term aspect not only to preservation, but also to background entomological agrolandscapes biodiversity level. Findings to the biodiversity condition of agrolandscapes establish convincingly ecological substantiation of working hypothesis, it allows proposing optimal ways of sanation of ecological condition of environment in Ukraine.
