Papka O. Factor analysis of the ecological niche of the common milkweed (Asclepias syriaca L.) as a basis of the invasion prognosis within agricultural lands

The regularities of spatial variation of ceonopopulation of common milkweed (As-clepias syriaca L.) within the agricultural lands of the Poltava oblast have been stated in the dissertation, that allows to the optimal strategy for control of weeds using remote sensing data based on the concept of the ecological niche. Opportunity seen geomor-phological indicators using digital elevation model as a ecological predictors of the common milkweed ecological niche, and investigated the patterns of their spatial varia-tion with regard to the configuration of the agricultural fields. Highlighted the major trends in the variability of plant cover agricultural land as the top environmental space common milkweed ecological niche and installed an explanatory ability features of relief to describe spatial patterns of vegetation.
