Impact of cocoa agricultural intensification on bird diversity and community composition. [PDF]
Conserv Biol, 2022 Abstract To meet the growing demand for chocolate, cocoa (Theobroma cacao) agriculture is expanding and intensifying. Although this threatens tropical forests, cocoa sustainability initiatives largely overlook biodiversity conservation. To inform these initiatives, we analyzed how cocoa agriculture affects bird diversity at farm and landscape scales ...

Conservation Biology, Volume 37, Issue 6, December 2023., 2023 Abstract Tropical montane bird communities are hypothesized to be highly sensitive to anthropogenic disturbance because species are adapted to a narrow range of environmental conditions and display high rates of endemism. We assessed avian sensitivity at regional and continental scales for a global epicenter of montane bird biodiversity, the tropical ...

Effects of forest fragmentation on avian breeding activity
Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract Biodiversity declines and ecosystem decay follow forest fragmentation; initially, abundant species may become rare or be extirpated. Underlying mechanisms behind delayed extirpation of certain species following forest fragmentation are unknown.

Biotropica, Volume 55, Issue 3, Page 650-664, May 2023., 2023 Our findings suggest a continuous shift in the frugivore community composition along the vertical gradient of a plant species fruiting across forest strata, from a few generalized frugivores in the understorey to a diverse set of specialized frugivores in the canopy.

Journal of Animal Ecology, Volume 92, Issue 3, Page 606-618, March 2023., 2023 This article accounts for species absences before occupancy analyses, addressing a long‐standing concern of whether absence is true or due to low sampling effort. The authors affiliate long‐term bird species trends with functional traits in a lowland tropical rainforest landscape in southeast Mexico to help guide land management and conservation ...

Variable relationships between trait diversity and avian ecological functions in agroecosystems
Functional Ecology, Volume 37, Issue 1, Page 87-98, January 2023., 2023 Read the free Plain Language Summary for this article on the Journal blog. Abstract The diversity of traits within animal assemblages has been shown to affect the magnitude of animal‐provided ecological functions. However, little is known about how consistent trait diversity effects are across ecological functions and ecosystems.

Biotropica, Volume 54, Issue 4, Page 852-859, July 2022., 2022 Deforestation and habitat fragmentation are known as the chief drivers of biodiversity loss. Habitat fragmentation in the Brazilian Amazon was found to affect the weight of birds that remained in isolated areas. Our results provide a novel analysis into how avian body mass responds to habitat fragmentation.

FRUGIVORIA E PREDAÇÃO DE SEMENTES POR AVES NO PARQUE ESTADUAL ALBERTO LÖFGREN, SÃO PAULO, SP
Revista do Instituto Florestal, 2007 As aves são importantes dispersoras e predadoras de sementes. O estudo de comunidades de aves frugívoras-granívoras e dos vegetais por elas utilizados é ainda pouco freqüente no Brasil.
