Spatial-typological structure and organization of the spring and spring-summer bird communities of the northern macroslope of the Kyrgyz ridge (Tien-Shan)

Hierarchical classifications were comprised and the spatial-typological structure of the spring and spring-summer bird population of the northern macroslope of the Kyrgyz Range was revealed. Using the linear qualitative approximation the descriptiveness of obtained classification and structural representations was calculated, and the variability of communities due to environmental factors was assessed. The structure and organization of the bird communities were compared in Tien Shan and Altai in these periods as well as in winter and early spring.
