The Spatial Organization of the Summer Bird Communities in the Urals

S. G. LIVANOV, V. A. KOROVIN, S. K. KOCHANOV

Abstract

The results of route accounts of birds performed at the territory of the Ural mountainous country (from the Sub-Polar to Southern Urals, inclusively) during the first half of summer (16.05-15.07) embracing generally the period from 1948 to 2000 are analyzed. The total length of the routes was about 3500 km. The total number of initial versions of the bird communities is 394. On the basis of the multidimensional factor analysis, a hierarchic classification of ornithocomplexes was composed and the main environmental factors forming the structure of communities were revealed. Comparative analysis showed that the specificity of the space and typological non-uniformity of ornithocomplexes in the Urals is exhibited even at the level of the systems of bird communities and is connected with the natural peculiarity of this physical geographic territory and the features of its development.
