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

Bornean tropical forests recovering from logging at risk of regeneration failure
Global 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 ...
