Thank you to our community for making McGill the outstanding university it is. McGill has been named the #1 university in Canada — and ranked 30th in the world — in the QS World University Rankings 2027. And we did it together! 

Had a great time meeting @drecrevisse.bsky.social in person this past weekend and discussing all things crayfish! 🦞🦞🦞

Did you see the news from yesterday? The Jane Goodall Hike for Hope takes place October 3rd and 4th – you can sign up now at HikeForHope.ca! We're inviting people across Canada to connect with the natural world and raise funds for the work that Dr. Jane championed. Photo: Chase Pickering

It's Jane Goodall Day! Today would have been Dr. Jane's 92nd birthday, and we plan to celebrate the only way we know how – by taking action. Want to do the same? Here are some ways you can get involved: Photos: Jane Goodall Institute of Canada / Katherine Holland

New Invasive Crayfish Publication Alert !!! 🦞🚨 In a watershed with no native crayfishes, the trophic niches of invasive virile crayfish and native fish overlap in the basin-wide niche space, but are mostly separate in the realized niche space. aquaticinvasions.arphahub.com/article/1831...

Such a loss. She was such a champion of conservation. She inspired me to become an ecologist and I am so grateful to have had the chance to see her speak, twice. We must all continue her legacy by fighting for wildlife conservation and continue to have hope 🤍 Rest in Peace, Jane🤍

Dr. Jane made an indelible mark on our understanding of chimpanzees and other species, and also of humankind and the environments we all share. She inspired curiosity, hope, and compassion in countless people, and paved the way for many others. #ThankYouJane #RememberingJane Photo: Marko Zlousic

I went on a solo hike today at Bronte Creek Provincial park with the goal of witnessing the beginning of the salmon run. The salmon haven’t made it this far west yet, but I was blessed to find this beautiful Cambarus robustus who had recently molted.

That’s a wrap on field season 2025! Check out some highlights from the 9 weeks spent on the St. Lawrence & Ottawa Rivers! 4/4

A reminder: There is no analogy in the fossil record for the magnitude & scale of the modern bioinvasion event. Driven by human activities, species are moving faster, farther, and in greater numbers than at any time in the history of life.

Anthony Ricciardi@ecoinvasions.bsky.social · 2y ago

Climate change is a 'natural' process now occurring ~10 times faster than the average rate after an ice age. Extinction is 'natural' but is now occurring 1000X faster than in past eras (apart from mass extinctions). Biological invasion is now at rates 100000X prehistoric levels of spp colonisations.

Blessed to find this beautiful electric blue Faxonius virilis while sampling the St. Lawrence for my doctoral work! This is a fairly rare phenotype for this native North American species!
