A tenure-track faculty position (Professor of Evolutionary Biology) is open at #UQAR in Quebec, Canada. Teaching in French. Application deadline: 4 May 2026. Details: www.csz-scz.ca/job-postings... 🧪
Un poste de professeure ou professeur en biologie évolutive est disponible à l' #UQAR! 🧪https://www.uqar.ca/emploi/professeure-professeur-regulier-en-biologie-evolutive/
Cette semaine à l’ #UQAR, j’ai présenté une réflexion sur l’écriture scientifique à l’ère de l’IA générative. La diapo ci-dessous résume mon message central. Il ne fait pas l’unanimité, de loin, même s’il rejoint la position du CRSNG, d’Elsevier, de la revue Science, etc.

I have known many cows, but I had never seen something like this! 🧪
À Davos, le premier ministre du Canada Mark Carney a ouvert son discours en français puis l’a poursuivi en anglais. Le président français Emmanuel Macron l’a commencé en anglais et l’a continué… en anglais. Cherchez l’erreur !
We contributed data from our Arctic study site at Bylot Island, Nunavut, Canada. It is fascinating to see how collaboration among many scientists from many countries can generate new insight into the ecology of our planet. 🧪🌿🌎🌐🦉🦑🦊🐻❄️

Un Rougegorge familier à Montréal: une première au Canada! Cela me fait très plaisir car c'est mon oiseau préféré depuis des décennies (avec l'Albatros d'Amsterdam). Le rougegorge me rappelle mon enfance européenne et l'albatros mon premier emploi de biologiste. oiseauxrares.qc.ca/index.php/fr/ 🌿🦉
A selection of studied species is shown, with each inset giving information for that species on its generation time (T, in years; also depicted by the black bar next to it), its diet (carnivore: C, herbivore: H, and omnivore: O) and whether the species is a migrant (M) or a resident (R). The inset shows the number of studies per taxon and trait category. Illustration credits for the species pictures taken from Wikipedia: Svalbard reindeer—Bjørn Christian Tørrissen, four-striped grass mouse—C.R. Selvakumar, silver gull—JJ Harrison, snow petrel—Samuel Blanc, northern giant petrel—Liam Quinn, green turtle—Brocken Inaglory, green-rumped parrotlet—Jam.mohd, Columbian ground squirrel—Martin Pot, red-winged fairy-wren—John Anderson, grey-headed albatross—John Harrison. Two species pictures were provided by the co-authors of this study: painted turtle (credit: FJ) and Atlantic yellow-nosed albatross (credit: SOp). The remaining pictures were taken from Pixabay (https://pixabay.com/photos/).
In Nature Communications, our paper led by Viktoriia Radchuk shows that phenological change mediates global vertebrate responses to temperature. The study compiles 213 time series of phenotypes and population sizes, including data from Bylot. Read: urls.fr/w7ZKp9 @natcomms.nature.com 🧪🌿🌎🌐🦉🦑🦊🐻❄️

Facial postures in primates. From Geena R. Ianni et al. Science Magazine, January 8, 2026.
The images below are unrelated to US politics. They show facial postures in a primate from Ianni et al. (Science, Jan 8, 2026), suggesting in a complex study that facial expressions are not purely involuntary or emotional, but at least partly intentional and cognitively driven. 🧪🌿🌎🦊

The January issue of Functional Ecology features our Arctic fox study showing how mechanistic models that combine species traits, landscape features, and energy-based behaviour help better quantify interactions in natural communities. A bit technical but very interesting. Read: urls.fr/DRn3xm

Chu et al. (urls.fr/Yeo6-K) estimate that cats kill ~60 million birds per year in Canada (possibly up to 197 M). Outdoor cats pose a serious risk to native birds. Potential responses include bylaws, education, social engagement, and trap-neuter-release programs. Think about it if you own a cat 🧪🌿🌎🦉🦊

In Science today: In the 1970s, the US Congress passed two landmark wildlife laws—the Marine Mammal Protection Act (MMPA) and the Endangered Species Act (ESA). Recent US actions now threaten their success. Surprising, right? Details: mleslie@ursinus.edu 🧪🌿🌎🦑🐻❄️

Today in 1972, as Apollo 17 astronauts Eugene Cernan, Harrison “Jack” Schmitt, and Ron Evans were rocketing toward the Moon, one of them looked back and took this iconic photograph, the first to capture a fully-illuminated round Earth and the only one taken by a human being.

Submitted a paper this week to Arctic Science proposing a new way to index collared lemming abundance in the polar desert. The method uses the urine marks lemmings naturally leave on plastic cards placed in their habitat for 48 hours. I call it the pee-card method! 🧪🌿🌎🦊 #wildlife #Arctic #North

Camera traps in the polar desert: admire this powerful American ermine in one of our custom photoboxes for lemmings and ermines (thanks @dfauteux.bsky.social for the design and advice). From our biodiversity monitoring site at CFS Alert, Nunavut. 🧪🌿🦊🌎 #wildlife #Arctic #North #uqar
Camera traps in the polar desert: this American ermine was already white on August 1st, photographed in a special photobox designed for lemmings and ermines (thanks @dfauteux.bsky.social for the design and advice). Summer is extremely short at CFS Alert, Nunavut. 🧪🌿🦊🌎 #wildlife #arctic #North #uqar

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

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
