Habitat Amount Shapes Ant Diversity in the Central Amazon

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Ant diversity in fragmented Amazonian forest landscapes is primarily driven by landscape‐scale habitat amount rather than fragment size, supporting the Habitat Amount Hypothesis (HAH) over Island Biogeography Theory (IBT). Consequently, conservation strategies should prioritize maintaining and restoring forest cover across human‐modified landscapes ...

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 ...

Phenotypic, Floristic, and Anthropogenic Drivers of the Pollen Niche of Amazonian Stingless Bees

open access: yesBiotropica, Volume 57, Issue 3, May 2025.
The pollen diversity and composition collected by Amazonian stingless bees depend on their body mass, tree composition, and urbanization. Further, bees have been collecting fewer pollen types since the 1970s. ABSTRACT Stingless bees (Apidae: Meliponini) are major pollinators in the tropics, supporting key ecosystem services.

Exposing illegal hunting and wildlife depletion in the world's largest tropical country through social media data

open access: yesConservation Biology, Volume 38, Issue 5, October 2024.
Abstract Globally, illegal sport hunting can threaten prey populations when unregulated. Due to its covert nature, illegal sport hunting poses challenges for data collection, hindering efforts to understand the full extent of its impacts. We gathered social media data to analyze patterns of illegal sport hunting and wildlife depletion across Brazil. We

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 ...
