In 2024, we found 3,500 vertebrate species predicted to have faced unprecedented temperatures. >1,250 already endangered. The window to act is real and monitoring what's going on in the field is crucial. Can we predict 9-months in advance? and in 10-years? more soon

Herbivory is a fundamental ecological process; treating it as harm (like recent work has suggested) misinforms conservation decisions about introduced herbivores. conbio.onlinelibrary.wiley.com/doi/10.1111/...

Check out our new letter in Conservation Biology where we argue that (re-)introduced large herbivores are often wrongly framed as harmful because herbivory is automatically equated with ecological damage - overlooking their potential to restore biodiversity and ecosystem functioning.

Start treating legends as information! This (work in progress) is a VSUP with model training points overlaid, and it shows that on the training dataset, most points are predicted with low uncertainty.
