Spatial Organization of Bird Communities in Central Siberia

Based on extensive data on the number and distribution of birds obtained during route surveys over the last 60 years, the classification of bird communities in Central Siberia is considered at the type level. The zonal and landscape–biotopic specificity of the identified types of ornithocomplexes is determined. The main directions of territorial changes in the bird communities are determined by afforestation and watering in combination with latitudinal zonality. Less significant differences in ornithocomplexes are associated with altitudinal zonation and built-up areas. The main natural and anthropogenic factors and hierarchy of their significance for the spatial differentiation of bird communities are established. The regional specificity of the spatial organization of bird communities in Central Siberia as compared with the East European and West Siberian plains is determined.
