The meetings of the CSEE/SCÉÉ have benefitted from hundreds of volunteers who helped further ecology and evolution research in Canada. Here are those from the 2025 meeting in Sherbrooke. My contributions were to talk others into doing most of the work and suggesting the color of the T-shirts.
Most of the volunteers for the 2025 meeting of the CSEE/SCÉÉ in Sherbrooke, Québec. The T-shirts illustrate some of the wildlife on Mt Bellevue, next to the UdeS campus. The meeting featured a land acknowledgment where I uttered a few words in Abenaki, a daycare, a nursing room and a substantial amount of French being spoken. The CSEE/SCÉÉ is strong on EDI, a key to its success.

My first #CSEE meeting was in 2012. At that meeting my introduction to the ecology and evolution community in Canada could not have been more memorable than being a part of over 1000 scientists from #CSEE2012 that marched on Parliament Hill as part of the #DeathOfEvidence march in #SCEECSEE20.

A fond post-CSEE meeting memory was meeting with Prof. Graham Bell after #CSEE2025 in Sherbrooke, co-founder and the first president of CSEE. As we sipped espresso at his favourite cafe in Montreal he shared with me the story of how CSEE came to be 20 years ago. A magical moment #SCEECSEE20
