Tendencies in the Dynamics of Birds Community in Agricultural Landscapes of the Steppe Trans-Urals at the Turn of the Century

The dynamics of the bird community in agricultural landscapes of the Trans-Urals steppe from the period of heavy agricultural intensification (1988 - 1992) until the decline of agricultural production (2000 - 2008) is considered. In the conditions of inten-sive agriculture, the agrophytocenosis structure and features of the agricultural cultivation technology serve as the key factors for the differentiation of bird communities in the steppe agricultural landscape.
