Spatial–typological structure and organization of the winter and early spring bird assemblages on the northern macroslope of the Kyrgyz Ridge (Tien Shan)

Resumo

The hierarchical classification was drafted and the spatial–typological structure of the winter and pre-spring bird assemblages is described for the northern macroslope of the Kyrgyz Ridge. The descriptiveness of the classification and structural representations, as well as an evaluation of the variability of communities in relation to environmental factors, are determined using a linear approximation of quality, structure, and organization of bird assemblages in these periods. In general, the heterogeneity of bird communities on the northern slope of Kyrgyz Ridge in winter and early spring periods is associated with the variability in heat and humidity, as well as the presence of built-up areas and single-crop agriculture. In winter, changes in avifauna are more gradual than in the early spring period.
