New paper out! 🐸 By incorporating abundance into #EcologicalNicheModels, we show that #climatechange may cause stronger population declines than traditional distribution models predict. Species may persist geographically while experiencing abundance losses. onlinelibrary.wiley.com/doi/full/10....

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. www.sciencedirect.com/science/arti...

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. onlinelibrary.wiley.com/doi/10.1111/...

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?
