Features of changes in the number and density of rodents in mosaic agricultural landscape of North-Western Black sea in 1961-2016

Abstract

Reflects the results of the stages of the study of bioclimatic and landscape-nanotechnik characteristics of the steppe zone of the North-Western part of the black sea region, as the formation of mosaic agrozootehnice mixed natural agroinnova Genesis. It is recommended to differentiate the dry steppe pjone only the territory South of the interfluve of the Dniester-Dnieper. A retrospective analysis allowed to argue that a significant amount of anthropogenic development in the process of transformation of the steppes into agricultural lands, stimulated a radical break with zonal ecosystems. This transformation of biocenosis occurred against the background of climate aridization and under the influence of anthropogenic actions. A structured approach to analytical generalization allowed to update selected issues and became the basis for the study. The obtained results allowed axiomatic to say about the deterioration of the conditions of existence for the available biotic complex, and also significantly affects the seasonal conditions of existence of rodents in the field of agricultural landscapes, directly and indirectly limiting their population status.
