Under pressure: assessing the vulnerability of two wetland birds to climate change Climate change drives significant shifts in species distributions, with consequences for individuals and entire ecosystems. While there has been an in…

New paper out!

We used ecological niche models to assess how climate change may affect two Neotropical wetland birds (Gubernetes yetapa and Heteroxolmis dominicanus).

Results suggest range shifts but loss of highly suitable areas.

Here, we investigated drivers of spatial variation in the abundance of a South American frui bat. Competitor richness emerged as the strongest predictor, outperforming climate, topography, and land cover, highlighting the role of diffuse competition.

Estudantes pretos e pardos ampliam presença na pós-graduação. Dados mostram evolução nas últimas três décadas, mas desigualdade racial no acesso ao mestrado e doutorado ainda é expressiva.

Bird responses to plant invasions are shaped by dispersal syndrome and historical disturbance: a meta-analysis - Biological Invasions Biological invasions significantly impact biodiversity by altering ecosystem attributes, potentially leading to species loss and environmental homogenization. These changes reduce habitat heterogeneit...

Our study published in Biological Invasions quantifies the negative effects of invasive plants on bird diversity. We found that herbaceous invasives and those with non-endozoochoric dispersal significantly decrease bird richness and abundance. Full paper here: link.springer.com/article/10.1...

It’s reached that time of year again where I gently suggest you hang on to your manuscripts and submit them early in 2026. Otherwise they’re likely to just sit on a virtual to do list for the next 3 weeks sending auto-reminders to editors/reviewers. 🎄

Are non-USA people still looking for a research position in academia in the US since Trump took office?
