At #NeoBiota2022 I started a survey among #invasionscience community about defining a 🐟 in 🇮🇸 under uncertainty whether it arrived naturally or was introduced If you work with #invasivespecies & have ~5min, take part! PLS retweet 🙂🇮🇸🐟 forms.office.com/r/dBSzVfsGvh 🧵for more info

Today I'm fulfilling a dream I've had for a while of going to the Muséum national d'Histoire naturelle in Paris. Just for today, writing my thesis can wait...

Finally got to meet Bimbus. The people that say you shouldn't meet your heroes were lying! 🥰 #FreeBimbus @al_vitruve Redpath Museum

A little teaser: Responses are currently more diverse than I would have expected 🤓 If you work #invasionscience, pls take part (& retweet 🙂) in my survey on defining an #alienspecies where uncertainty remains on how it arrived in its new habitat 🐟🇮🇸 #invasivespecies link ⬇️

The The Ricciardians is curling today! A lab bonding outing as our youngest honorary member watches with his dad

Rusty crayfish get a lot of attention across the Great Lakes Basin, and rightfully deserved. But there are other invasive crays we are closely watching out for: Red Swamp Crayfish and Marbled Crayfish among them. Never release purchased crayfish into the wild, and obey all laws!

What this picture doesn't show is that I walked the stage with my chosen study organism (or at least a 3D puzzle of one), hiding in my Master's hood 🥰

Our new study examines the transfer of microplastics in freshwater communities. In lab expts, Gen D'Avignon tested how trophic & nontrophic interactions of co-occurring benthic animals (round goby, quagga mussel, amphipod) affect their uptake of microbeads: sciencedirect.com/science/articl…

We now have a first record of the #invasive asexual Marbled #crayfish in the wild in Canada and North America. If you have these crayfish as a pet DO NOT release them in the wild!

Just finished a fantastic Dinosaur Park Project field season #DPP2023 incl 2 dino skulls, a multitaxic leaf site, and progress on drone surface mapping the entire park McGill University Redpath Museum McGill Biology

Excited to be announcing my first ever published paper 🥰 If you're interested in quantifying the reduction in feeding of gravid marbled crayfish as well as the impacts climate change may have on their reproduction read on!

In case you missed it, marbled crayfish have been found in Canada😞

Preprint on one of my PhD thesis chapters is now out!

So proud to see him grow up into the penguin he has become today 🥲 When he was first given to me 20 years ago as a Christmas present I don't think anyone would have guessed we'd both be doing our PhDs together
