Check out our new paper on adopting a trait-based framework for protist diversity! We make the case for a unified protist trait database, how to build it, and how it could transform research on protist ecology and evolution.

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!
