Temporal Variation in Birds and Fruits Along an Elevational Gradient in Costa Rica
We studied temporal fluctuations in fruit production by plants and in pop- ulations of understory fruit-eating birds at three elevations (50, 500, and 1000 m) in Costa Rican wet forests over a 12-16Expand

BIRD ASSEMBLAGES IN SECOND-GROWTH AND OLD-GROWTH FORESTS, COSTA RICA: PERSPECTIVES FROM MIST NETS AND POINT COUNTS
Abstract Second growth has replaced lowland forest in many parts of the Neotropics, providing valuable habitat for many resident and migrant bird species. Given the prevalence of such habitats andExpand

Breeding Birds of Isolated Woodlots: Area and Habitat Relationships.
We investigated breeding bird communities of isolated woodlots (1.8-600 ha) in east-central Illinois during three summers (1979-1981) to compare the influence of area and habitat on communityExpand

DIVERSITY OF BIRDS ALONG AN ELEVATIONAL GRADIENT IN THE CORDILLERA CENTRAL, COSTA RICA
Abstract Species diversity and community composition of birds change rapidly along elevational gradients in Costa Rica. Such changes are of interest ecologically and illustrate the value ofExpand

NEOTROPICAL FOREST BIRD COMMUNITIES: A COMPARISON OF SPECIES RICHNESS AND COMPOSITION AT LOCAL AND REGIONAL SCALES
Abstract Species richness and composition of Neotropical forest bird communities vary spatially at both large and small scales, but previous comparisons based on 100 ha plots have not replicatedExpand

Predicting species distributions from herbarium collections: does climate bias in collection sampling influence model outcomes?
Aim Species distribution models and geographical information system (GIS) technologies are becoming increasingly important tools in conservation planning and decision-making. Often the rich dataExpand

Nested Subsets and the Distribution of Birds on Isolated Woodlots
Abstract. Distribution of bird species among isolated habitat patches (e.g., woodlots in an agricultural landscape) often appears to be nonrandom; species present in small, species-poor patches alsoExpand

Estimates of Apparent Survival Rates for Forest Birds in Eastern Ecuador
Knowledge of survival rates of Neotropical landbirds remains limited, with estimates of apparent survival available from relatively few sites and species. We used capture–mark–recapture models toExpand

Species composition of bird communities and the conservation benefit of large versus small forests
Abstract Preservation of many species depends on the existence of parks and wildlife reserves that form islands of natural habitat. Isolated patches of forest provide habitat islands for many birdExpand

Diversity, Prevalence, and Host Specificity of Avian Plasmodium and Haemoproteus in a Western Amazon Assemblage
We used PCR and DNA sequencing to screen for haemosporidian parasites (Haemoproteus and Plasmodium) in 2,488 individual birds from 104 species and 22 families, primarily understory suboscineExpand
