Effects of proximity to urban areas on a riparian bird community in remnant Atlantic Forest in southeastern Brazil

摘要

The goal of this study was to evaluate the effect of urban activities on the structure and composition of a bird community in riparian forests in the state of S?o Paulo, Brazil. The study was carried out in seven areas of remnant riparian forest where fixed points have been established to sample bird species. Richness, diversity, abundance, frequency and trophic groups were used as metrics of the bird community. At each point measurements were taken for: (1) habitat characteristics: average height of trees, number of trees above 2m, number of shrubs.
