Spatial-typological structure of bird communities in coniferous and deciduous forests of the Northern Volga region.

摘要

Based on materials collected during continuous year-round strip censuses, the spatial heterogeneity of bird communities in coniferous and deciduous forests of the Northern Volga region was analyzed for the first time and the key factors determining it were identified. A spatial-temporal classification of bird communities of the study area was made, and a quantitative estimate of the strength and generality of the relationship between the spatial heterogeneity of bird communities and environmental factors is given. The spatial-temporal structure of bird communities is mainly determined by forest cover, seasonal variation in heat supply, tree species composition, build-up area, and relief.Notes Translated from Sibirskii Ekologicheskii Zhurnal (2012) 19 (1) 107-114 (Ru).
