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.
This study was conducted in the tropical moist deciduous forest in Bangladesh to describe the species composition, diversity, and the forest structure. There were three plots established in Ranishonkoil, Ruhia, and Baliadangi forest beat in Thakurgaon. A total of 126 tree species, 1,991 stems (66...
The spatial structure of the total bird population at the level of communities has been studied in a definite area at the boundary between northern open forests and forest-tundra. The boundaries of communities have been delimited by mapping out areas with a homogeneous species composition. The pa...
Stand structure and spatial distribution of Picea jezoensis (Siebold et Zucc.) Carriere on Mt. Gyebang, Korea was investigated to provide information on the structural characteristics and the maintenance of P. jezoensis population in northern temperate mixed coniferous forests. Height and diamete...
Majority of plant species in northern temperate deciduous forests are restricted to the ground layer, but the importance of colonization processes relative to environmental filtering in structuring spatial variation in ground-layer plant communities is poorly understood.2. Using multivariate an...
Several phylogeographic studies in northern Mesoamerica have examined the influence of Pleistocene glaciations on the genetic structure of temperate tree species with their southern limit by the contact zone between species otherwise characteristic of North or South America, but few have featured...
The practice of careful logging has been mandated in northeastern Canada’s coniferous and mixedwood forests as a means of protecting natural regeneration while minimizing soil disturbance by machinery. This practice imposes evenly spaced, parallel trails for circulation of harvesting machinery,...
Deciduous forests are regenerating following industrial disturbance in large areas of eastern North America and western Europe. To understand the long-term process of forest regeneration, the microenvironment and flora of post-industrial plots were compared with non-industrial controls at two 19t...
Biological invasions have important ecological impacts at both local and global levels, affecting biodiversity, ecosystem functioning, and economic sustainability. The study of invasions requires specific methodological approaches to gain rapid insight into the spatial and temporal dynamics of th...
The joint and independent effects of dominant tree species, forest patch spatial attributes, and forest structure and management as drivers of plant species richness and composition in small forest patches scattered within an intensive agricultural landscape were addressed.In a landscape with sca...
Different organisms respond to landscape configuration and spatial structure in different terms and across different spatial scales. Here, regression models with variation partitioning were applied to determine relative influence of the three groups of variables (climate, land use and environment...
