Tree-Cover Gradients Modulate the Taxonomic and Functional Diversity of Birds in Amazonian Cattle-Ranching Landscapes

Alexander Velásquez Valencia, Jenniffer Tatiana Díaz-Cháux, María Argenis Bonilla…·Fernando Casanoves

This study examines how tree-cover gradients affect bird taxonomic and functional diversity in Amazonian cattle-ranching landscapes, finding differential impacts on guild-level richness, evenness, and functionality across cover types.
