We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.

Social media highlights the overlooked impact of cats on arthropods
The impact of domestic cats on vertebrate biodiversity is unequivocal; however, we still know little about their effects on arthropods. By analysing over 17,000 photos and videos from social media platforms (iStock and TikTok), we documented 550 predation events of cats on arthropods.
