Journal of Avian Biology, Volume 2026, Issue 3, May 2026.The Northern Andes, acting both as barrier and corridor, exert strong influence in Neotropical biodiversity. Still, the diversification of foothill taxa inhabiting ecotonal zones between lowland rainforest and montane environments in this region remains poorly understood.

Beyond species means – the intraspecific contribution to global wood density variation
New Phytologist, Volume 249, Issue 6, Page 2630-2651, March 2026.Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Ontogenetic shifts in wood anatomy and leaf traits in tropical dry forests
New Phytologist, Volume 249, Issue 2, Page 848-859, January 2026.Summary Trees experience changes in environmental conditions and biophysical constraints as they grow that may lead to shifts in functional traits. While ontogenetic shifts in leaf traits are relatively well understood, changes in wood anatomy traits from seedlings to adults are less clear, especially in tropical dry forests where drought strongly ...
