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

open access: yesEcological Entomology, Volume 51, Issue 3, Page 558-569, June 2026.
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 ...

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

open access: yesBiotropica, 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.
