摘要
The spatial heterogeneity of bird assemblages has been evaluated based on the results of transect bird counts taken in different areas of the Northern Urals from June 1 to July 15 in 1966 to 2005. On the whole, 154 bird species were recorded over the routes extending for about 3000 km. A total of 126 variants of bird assemblages were included in calculations. Using multidimensional factor analysis, a hierarchical classification of these assemblages has been constructed, and basic environmental factors having an effect on their structure have been revealed. The results show that the spatial organization of bird assemblages in the Northern Urals is most similar to that in the Northeastern Altai.
