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...

Looks like a Cuban Tree Frog (Osteopilus septentrionalis), invasive but still cute. Great shot by the way!

Just a few chapters in and I’m already in love!
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 !
