Forest Cover and Geographic Distance Shape Ant Assemblages in the Southwestern Brazilian Amazon

Ecology and Evolution, Volume 15, Issue 11, November 2025.
We investigated how forest cover, precipitation, and spatial distance influence ant species richness and composition in the southwestern Brazilian Amazon. We found that forest cover increases species richness, especially of forest specialists, while spatial distance is the main driver of variation in species composition.

Seasonal Forest Resources Support Fish Biomass in Floodplain Lakes of an Amazonian Tributary

Freshwater Biology, Volume 70, Issue 11, November 2025.
ABSTRACT The Flood Pulse Concept is a foundational ecological theory that emphasizes the critical role of lateral connectivity between a river channel and its floodplain. Many tropical rivers inundate the surrounding floodplain in the flood stage, thereby receiving large amounts of terrestrial organic matter that can be decomposed by microbes and ...

Surviving in a Warming and Fragmented World: Long‐Term Population Dynamics of the Lizard Gonatodes humeralis

Austral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Climate change presents significant challenges to species survival; however, the long‐term effects on tropical lizard populations remain poorly understood. Previous studies have predicted contrasting outcomes, with some forecasting a high risk of extinction due to rising temperatures, while others suggest greater resilience in tropical ...
