Competition and the structure of bird communities.

The effects of habitat fragmentation on bird communities in Hyrcanian forests (Case study: Gorgan Township)

Diversity of bird's communities on dumpsite and sewage stabilization ponds of Moshi Municipal, Kilimanjaro, Tanzania

Urban development is rapidly expanding across the globe and is a major driver of environmental change. It is important to understand how bird species responds to urbanization. Therefore I conducted a qualitative study of birds associated with waste sites such as dumpsite and sewage stabilization ponds was carried out on Moshi municipal. The study assessed the diversity between dumpsite and sewa...

Breeding birds were censused along four elevational gradients in the Adirondack Mountains, New York, and the Green Mountains, Vermont. The bird communities of the four gradients were basically similar in species composition, richness and amplitude patterns. Three measures of species diversity decreased with increasing elevation. Low-elevation communities contained higher proportions of rare spe...

Linking optimal foraging behavior to bird community structure in an urban-desert landscape: field experiments with artificial food patches.

Urban bird communities exhibit high population densities and low species diversity, yet mechanisms behind these patterns remain largely untested. We present results from experimental studies of behavioral mechanisms underlying these patterns and provide a test of foraging theory applied to urban bird communities. We measured foraging decisions at artificial food patches to assess how urban habi...

A taxonomic, functional, and phylogenetic perspective on the community assembly of passerine birds along an elevational gradient in southwest China

Integrating multiple facets of biodiversity to describe spatial and temporal distribution patterns is one way of revealing the mechanisms driving community assembly. We assessed the species, functional, and phylogenetic composition and structure of passerine bird communities along an elevational gradient both in wintering and breeding seasons in the Ailao Mountains, southwest China, in order to...
