Another day of Ford nonsense…..

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.

Emma Johnston was a visionary scientist, environmentalist and leader, with an abiding hope for humanity The University of Melbourne Vice-Chancellor, who has died aged 52, was driven by a deep love of science and a desire to safeguard the planet’s future.

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...

Why Britain has a deer problem Deer numbers have rocketed over the last 40 years and particularly since the Covid-19 pandemic.

Methinks it's more of a people problem. Especially people who think contraception is part of the solution. www.bbc.com/news/article...

Join us August 25th for a herps Bioblitz at île du Marais (Sainte-Catherine-de-Hatley). Spend an afternoon observing reptiles and amphibians, while contributing to citizen science by uploading your observation to iNatualist 🐸🐢🐍! @qcbs.ca @inaturalist.bsky.social @usherbrooke.bsky.social

This week I had the opportunity to represent Université de Sherbrooke at #CSEE2025, presenting my research on Eastern chipmunk behaviour and life-history.
I am honoured to have been able to attend, and discuss the future of ecology and evolution with both new and old colleagues and friends.

I had the opportunity of presenting the first preliminary results of my project this week at #CSEE2025, which we hosted in Sherbrooke. I’m extremely grateful to have met amazing researchers and fellow students, most of which, love frogs as much as I do 🐸.

With field work about to finish, here are a some pictures from the last few weeks 🐸!

Fantastic Dream Team of volunteers! #CSEE25

What a great team of co-directors!
Quelle belle équipe de codirection !
