Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Contexts of Anointing Behavior in a Group of Blond Capuchin Monkeys (Sapajus flavius) Inhabiting an Atlantic Forest Fragment

American Journal of Primatology, Volume 88, Issue 1, January 2026.
Wild blond capuchin anoints with millipede species that secrete a chemical capable of repelling ectoparasites, suggesting a self‐medicative function. Social and solitary anointing bouts occurred at similar frequencies, but with greater engagement by adult males, indicating that anointing is a multifunctional behavior.

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

Journal 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.

How Management Practices Shape the “Local Habitat Signature” That Modulates Bird Communities in Urban Green Spaces

Biotropica, Volume 58, Issue 1, January 2026.
Local scale factors, not just the broad urban gradient, are the key drivers of urban bird communities. Our multi‐scale study found that specific management practices, such as managing leaf litter depth or the presence of unmanaged tall grass, explained the largest portion of variation in bird composition.
