Les castors débarquent en Arctique. J'en ai parlé avec le journaliste scientifique Joël Leblanc @zapiens.bsky.social pour le magazine L'actualité. À lire à lactualite.com/environnemen.... #uqar #wildlife #changementclimatique #faune

J'ai fait plusieurs entrevues ces derniers jours à la radio de Radio-Canada pour parler de nos recherches à l' #uqar sur les ours polaires. Merci à @emiliedesjardins.bsky.social qui y a BEAUCOUP contribué. Lien vers une entrevue représentative: urls.fr/AC3B_N

Integrating predator energetic balance, risk‐taking behaviour and microhabitat in functional response to untangle indirect interactions in a multispecies vertebrate community

In Functional Ecology, we integrate predator energy balance into functional responses to better understand tundra species interactions. This paper reflects major field and modelling efforts by our #UQAR team and colleagues. Read: bit.ly/49p6brL 🧪🌿🌎🦊 #wildlife #movementecology #arctic #fox #ecology

Cette semaine, j’ai cosigné dans La Presse un texte avec d’autres universitaires et chercheurs pour demander au gouvernement du Québec de renoncer à affaiblir la gouvernance climatique de la province. #uqar. À lire ici : bit.ly/4ilGWJz

In Molecular Ecology, we trace the origins of domestic Arctic fox lineages by comparing genomes of farmed and wild foxes. Congrats to Christopher Cockerill for leading the study; I contributed modestly with samples from Bylot Island. Read: bit.ly/4nRagIJ. 🧪🌿🌎🦊 #wildlife

NOAA aerial imagery is coming in. Hurricane Melissa literally turned western Jamaica from green to brown. Vegetation damage is immense — recovery will take years.

Stunning illustration of mimicry! Common cuckoo eggs (top row) imitate the eggs of their host species (bottom row). The 30 October issue of Science explains this dazzling coevolution with genomic data — though I admit, it’s complex enough that I’d struggle to teach it! 🧪🌿🌎🦉

Un renard arctique à Paris ! Merci à @audelalis.bsky.social de m’avoir fait découvrir l’exposition Désert au Muséum national d’histoire naturelle. Je visitais les lieux pour préparer une rencontre scientifique internationale qui, je l’espère, aura lieu au Muséum dans quelques années. 🧪🌿🌎🦊

'What makes PhD students happy? Good supervision. Supervisors who invest in positive mentoring relationships with their PhD candidates also reap the benefits for their own research.' Nature, 23 Oct 2025. I’m amazed this is framed as a revelation — it’s pure common sense. 🧪🌎🌐

Studying Arctic foxes on Bylot Island (Nunavut, Canada), or being studied by them? The collared fox in this photo is a male named Ram, captured this summer. Great shot by my excellent MSc student Laurianne Dumont. 🧪🌿🌎🦊 #MovementEcology #wildlife

Camera traps in the polar desert: A polar bear grazing on vegetation beside one of our arthropod traps — a rare sight in our biodiversity monitoring study area at CFS Alert, Nunavut, Canada. Not sure why they do this, but it’s not unheard of. 🧪🌿🌎🦊🐻‍❄️ #wildlife

Animals don’t know they’ll soon be released when we trap them for tagging. I couldn’t help but wonder what went through the mind of this Arctic fox as I held her (Bylot Island, Nunavut, Canada, summer 2025).🧪🌿🌎🦊

Last year I set up four polar bear sampling stations in our study area at Alert (Nunavut, Canada). Goal: collect pictures and hairs to document the understudied Arctic Basin population. This one, from 8 August 2025, is our first good photo ! 🧪🌿🌎🌐🦑🦊 (barbed wire for genetic hair collection visible)

You don’t need to love birding to enjoy Northern Gannets gliding at sunset over a calm sea. Picture taken during a boat trip off Prince Edward Island, Canada on August 4th, 2025.🌿🌎🦉🦑

You know you love birding when… you double-check that this young Great Black-backed Gull has all 12 retrices (tail feathers) as expected. Picture taken during a boat trip off Prince Edward Island, Canada on August 4th, 2025.🌿🌎🦉🦑

You know you love birding when… you find the molting pattern in the primaries of this adult American Herring Gull both 'very interesting' and 'aesthetic.' Picture taken during a boat trip off Prince Edward Island, Canada on August 4th, 2025.🌿🌎🦉🦑

Took hundreds of pictures this summer on Bylot Island (Nunavut, Canada), but only now had time to go through them. This molting Arctic fox giving a cute nose-lick while staring at me in the tundra is one of my favorites. 🌿🦊
