Functional Biogeography and Ecological Strategies of Trees Across the Amazon–Cerrado Transition

open access: yesJournal of Vegetation Science, Volume 36, Issue 5, September/October 2025.
We investigated how tree functional traits vary across six vegetation types in the Amazon–Cerrado transition and identified key environmental drivers of these patterns, revealing a functional continuum from savanna to forest formations. Our results highlight the ecological distinctiveness of this transition zone and demonstrate that accounting for ...
