Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

open access: yesRemote Sensing in Ecology and Conservation, Volume 11, Issue 4, Page 394-410, August 2025.
We analyzed the effects of fire on secondary forests' vertical structure in different successional stages using lidar metrics. Our results show that independently of the successional stage, secondary forests that experienced fire were more degraded than unburned secondary forest areas. Overall, our results show that forests in early successional stage (

The Rapid Recovery of a Caatinga Dry Forest is Mediated by Disturbance‐Adapted Species

open access: yesBiotropica, Volume 57, Issue 4, July 2025.
Overall, regenerating and old‐growth forest stands exhibited similar plant diversity across all ontogenetic stages, with a negligible role played by forest stand age, precipitation, and chronic human disturbance. Species exclusively recorded as adults or seeds were mostly dispersed by animals, indicating that several species fail in either dispersing ...

Fire Effects on Bird Communities From Seasonally Flooded Forests Along Amazonian Black Water Rivers of the Negro River Basin

open access: yesDiversity and Distributions, Volume 31, Issue 5, May 2025.
ABSTRACT Aim Fire significantly contributes to Amazonian degradation, with igapó forests (seasonally flooded by blackwater rivers) being especially vulnerable. Igapó forests support species adapted to seasonal flooding, making fire a critical threat to these specialised organisms.

Bornean tropical forests recovering from logging at risk of regeneration failure

open access: yesGlobal Change Biology, Volume 30, Issue 3, March 2024.
The study investigates the impact of active restoration, such as enrichment planting, on the regeneration of logged forests in North Borneo. It found that while such interventions increase initial seedling production in logged forests, this is followed by higher seedling mortality and species diversity or evenness are not enhanced compared to natural ...
