The UdeS made me Emeritus. This is a big deal in francophone universities. As an ethnic voter who speaks with an accent, it is not always easy to feel at home in Québec, but I always was at home at the Université de Sherbrooke, very grateful.

Canada’s first European Robin (Erinthacus rubecula)! Only the fourth observation in North America. Most likely a vagrant from a ship. There was just over 100 observers this morning. January 10th 2026, Montréal, QC www.inaturalist.org/observations...

Very sad to hear of this. I met Emma at conference I organized in Montreal in 2019. She had a stellar reputation, so I invited her as a keynote speaker. She was charismatic & inspirational. Students in particular told me they enjoyed meeting her. Wonderful person. theconversation.com/emma-johnsto...

Colossal Bioscience did not revive dire wolves, despite a sensationalist Time Magazine cover story. Making genetically modified animals that are cosplaying as extinct species is not de-extinction.

Blown away by this paper on body size variation among 11,264 (!!!) measured plethodontid salamanders over an elevational gradient. Super surprised to see that it is not temperature that has the main explanatory role, but mostly humidity and precipitation 🧪🦎 onlinelibrary.wiley.com/doi/full/10....
The Structure Equation Model (a fancy kind of Path model) from the paper, constructed of four factors influencing body size: elevation, which acts indirectly via its effect on temperature and precipitation; temperature, which acts directly only weakly, but more strongly via a direct effect on humidity; precipitation, which acts directly on body size but also has a significant relationship with humidity; and humidity, which has a direct influence. It's an elegant figure. There's a salamander representing body size, illustrated by one of the coauthors, Fleming.
