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:

Assessing differences in food web metrics in freshwater ecosystems after the invasion of Northern crayfish (Faxonius virilis) Aquatic invasive species are among the greatest threats to freshwater biodiversity. Crayfish are especially robust freshwater invaders that can compete on various trophic levels simultaneously. The No...

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.

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🤍

Cambarus robustus at Bronte Creek Provincial Park.

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.

Oh no! 😰

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.

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!

Check out our new paper "Bioclimatic, terrain, and specific peatland composition are major drivers of woodland caribou winter habitat suitability in northern Ontario". I am grateful to have worked on this important topic with this amazing team!
