The future of tropical forests depends on their ability to resist and recover from multiple disturbances. Here, we evaluated how edge effects, experimental fires, extreme droughts, and blowdowns reshaped forest structure, composition, and functional traits over two decades in the Amazon–Cerrado transition. Initially, forests resisted low-intensity fires, but subsequent high-intensity fires during severe droughts sharply increased susceptibility to further disturbances. Along forest edges bordering agriculture, these compound disturbances drove losses of tree species richness, declines in Amazonian forest-specialist
species, and shifts toward generalists with broad distributions, indicating increased compositional homogenization (i.e., reduced taxonomic diversity and dominance of generalist species).
Protected areas are effective on curbing fires in the Amazon
The assessment of whether protected areas (PAs) inhibit environmentally damaging fires is challenged by three sources of bias: (i) non-random site protection, (ii) influence of simultaneous land use and environmental changes, and (iii) unobservable time-invariant...
