Strong Variation in Land‐Use Change Impacts on Tropical Avian Phylogenetic Diversity Between Ecoregions Highlights the Need to Sample Large Spatial Scales
Global 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.Giovanny Pérez, Simon C.

Integrative Conservation, Volume 4, Issue 4, Page 600-615, December 2025.Only 1541 (34.2%) of 4503 recognized non‐passerine bird species are held in ZIMS institutions worldwide. Approximately ~83% of the species kept globally are classified as non‐threatened and ~16% as threatened. To improve the conservation of threatened birds, a shift toward keeping threatened species should be considered within ex situ management ...Anna Wahle, Clara Graßmann, Emily Zell, Laura Leiss, Bernd Marcordes, Theodor B.

The effects of rivers as barriers for species dispersal can be expected to vary according to both species traits and the characteristics of rivers themselves. In this context, our aim was to investigate dissimilarities in species composition across opposite banks of two major Amazonian rivers, the Juruá and the Tapajós, and relate them to ...</span><br><span class="r_sub"><i>M.
