That is too bad. I do have students on site doing good work, so data are collected, but it is sad not to be there. Good luck with your projects.

Drove 10 hours to Canadian Forces Base Trenton to catch a C-130 Hercules to Greenland & Ellesmere. Flight cancelled (plane needed for forest fire response in Canada). Drove 10 hours back home. Oh well, this is part of Arctic field work! Next year will be better. Picture: inside a Hercules (2024).

Just back from animal ecology field work on Bylot Island, Nunavut. Taking a moment to share this picture of me walking near one of our beautiful short-term camps (background=Baffin). Not all work was that glamorous; I’ll share more ‘usual’ moments later. Now heading to Alert, Ellesmere Island.🧪🌿🌎🦉🦊🐻‍❄️

L’Ile Bylot, en face du village de Pond Inlet au Nunavut. C’est là que je rejoindrai demain mes étudiantes de l’ #UQAR, déjà arrivée il y a un mois pour nos recherches sur la faune arctique.

Scientific American covered our #MovementEcology work on Arctic foxes a couple of years ago, beautifully illustrating their continental-scale dispersal across Arctic Canada, through islands and sea ice straits.🧪🌿🌎🦊🌐🦑🐻‍❄️ #wildlife. If interested, enlarge map below (with full reference to article).

I'll be heading to Bylot Island (Nunavut) in a few days to study Arctic fox movements and Arctic biodiversity. My students are already there. Watch the video to feel what it’s like landing in the snowy tundra around mid-June (helicopter sound included). Impressive. 🦊🧪🌿🌎🌐 #wildlife

Les recherches sur la biodiversité de l'Arctique sont fascinantes et cruciales mais coûtent incroyablement cher. C'est toujours un combat de réussir à les mener; je l'ai expliqué à la journaliste Matisse Harvey de Radio-Canada. Lire à lc.cx/EZlUw- 🧪🌿🌎🌐🦊 #uqar #wildlife

White-nose syndrome has very severe consequences for North American bats, yet it’s largely overlooked by the public because neither bats nor the syndrome make for attractive photos. Exciting new discoveries on the syndrome in the latest Nature (lc.cx/5QJ8kM) 🧪🌿🌎🌐 #wildlife

Causes of decline include climate change on their Arctic breeding grounds, as well as collisions with vehicles, rodenticide poisoning, electrocution, and diseases such as avian influenza on their wintering grounds. Curbing the artificialization of natural habitats is essential to protect wildlife.

The Snowy Owl, Québec’s provincial bird, has just been assessed as Threatened in Canada. This species nests in one of the fastest-changing climates on the planet. I took this photo of a Snowy Owl chick in our Alert biodiversity monitoring area (Nunavut) during the 2019 lemming peak. 🌿🌎🦉 #wildlife

Le harfang des neiges, emblème du Québec, est désormais « menacé ». J'en ai parlé, ainsi que de la biodiversité, avec Denis Leduc sur Radio-Canada : lc.cx/ndTqjY (15h46). J'avais pris cette photo de poussins à Alert (Nunavut, Canada) lors du pic de lemmings de 2019. #uqar 🌿🌎🦉 ‪@qcbs.ca

Sometimes you dig through your old pictures and find gems like this baby North American porcupine in Parc national du Bic (Quebec). We spent nights in the woods studying their ecology, and I learned that you CAN pet a porcupine—just make sure you’re going in the right direction! 🧪🌿🌎🦊 #wildlife
