Strong Variation in Land‐Use Change Impacts on Tropical Avian Phylogenetic Diversity Between Ecoregions Highlights the Need to Sample Large Spatial Scales

open access: yesGlobal Change Biology, Volume 32, Issue 1, January 2026.
Forest conversion for agriculture is a major cause of biodiversity loss in the tropics, but its impacts depend on how broadly they are measured. Using data from across Colombia, one of the most biodiverse countries in the world, we examined how deforestation for cattle farming affects the evolutionary history of bird species.
