Disappearance of insectivorous birds from tropical forest fragments.
Determining the impact of forest disturbance and fragmentation on tropical biotas is a central goal of conservation biology. Among tropical forest birds, understory insectivores are particularly sensitive to habitat disturbance and fragmentation, despite their relatively small sizes and freedom from hunting pressure. Why these birds are especially vulnerable to fragmentation is not known. Our d...
متن کاملRegional forest fragmentation and the nesting success of migratory birds.
Forest fragmentation, the disruption in the continuity of forest habitat, is hypothesized to be a major cause of population decline for some species of forest birds because fragmentation reduces nesting (reproductive) success. Nest predation and parasitism by cowbirds increased with forest fragmentation in nine midwestern (United States) landscapes that varied from 6 to 95 percent forest cover ...
متن کاملConservation Biology: Predicting Birds' Responses to Forest Fragmentation
Understanding species' ecological responses to habitat fragmentation is critical for biodiversity conservation, especially in tropical forests. A detailed recent study has shown that changes in the abundances of bird species following fragmentation may be dramatic and unpredictable.

متن کاملEvaluation of an Arthropod Sampling Technique for Measuring Food Availability for Forest Insectivorous Birds
—I provide a detailed description of an arthropod sampling technique, ‘‘branch clipping,’’ and evaluate its efficacy in measuring food availability for three foliage-gleaning migratory warbler species wintering in Jamaica. I incorporated foraging observations into the sampling protocol to facilitate a match between the distribution of branch-clip samples and the distribution of warbler foraging...
