Urban rendezvous: Spatiotemporal overlap is more important than abundance and trait matching for urban plant–pollinator interactions

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our study shows that the generalized structure of urban plant–pollinator interactions is mirrored in the mechanisms that shape them, as interactions are governed primarily by less restrictive drivers such as abundance and spatiotemporal overlap rather than by trait matching.

Trait coordination reveals the fast–slow plant economics spectrum along the vertical canopy profile in central Amazonian forests

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3596-3610, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding how environmental drivers affect tree functioning is essential to improve predictions of tropical forests' response to climate change. While functional traits directly influence tree performance, our understanding of how canopy environments shape their ...

Precipitation and Temperature‐Dependent Locomotor Performance Drive the Abundance of a Neotropical Lizard

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
We investigated how climate and ecophysiology affect the demography of the lizard Tropidurus oreadicus in the Brazilian Cerrado. While lizards were more frequently captured in the dry season, their abundance peaked during the rainy season when their locomotor performance was highest.
