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.

STRUCTURAL ORGANIZATION AND SPECIFICITY OF TERRITORIAL LINKS AMONG BIRDS OF INNER-MOUNTAIN AND HIGH-MOUNTAIN DAGHESTAN

The results of our bird counts carried out in 1996-2017 in the Inner-mountain and High-mountain Dagestan are analyzed. The bird specific composition, average popula-tion abundance and ecological structure of the avifauna in two difficult-to-reach mountain areas of the republic are described for the first time.
