Our last study on the cover of Ecology 🐹❄️
Say hello to our October cover star! This Arctic lemming was photographed by @MathildePoir during a study that explores how winter weather events like melt-freeze and rain-on-snow affect these high-latitude critters Browse the full issue here: esajournals.onlinelibrary.wiley.com/toc/19399170/2…
Excited to share our new paper in @ESAEcology ! ❄️ Our 17-year study shows that even moderate winter events (rain-on-snow, melt-feeze) can negatively influence lemming winter reproduction and population growth. 🐹 Open-access available here: 🔗 doi.org/10.1002/ecy.70…

New paper in @SpringerEcology! 🐹❄️ Our study shows the importance of deep snow in #lemming habitats, providing them with favorable conditions. But there's a tradeoff: deeper snowpack means tougher snow, impacting lemming winter reproduction negatively. ➡️rdcu.be/dfhux

Joignez vous à nous pour cette école doctorale sur la neige! ❄️
Cette école de pointe se penchera sur les processus dynamiques de la neige arctique et sa relation avec l'humain, le climat et l'environnement dans un Nord en mutation. ❄️ Soumettez avant le 15 janvier : bit.ly/3Oh4UGt #sentinellenord @USherbrooke @CRSNG_NSERC

Les intrigantes variations cycliques des lemmings n'ont pas fini de surprendre @museedelanature @FSGulaval @cen_nord bit.ly/3IAT6Ms

Lemmings: la prédation des femelles au cœur des variations cycliques
La mortalité différentielle des femelles ferait en sorte qu'elles sont trois fois moins nombreuses que les mâles lorsque la population atteint un creux de vague
Shrub branches are great thermal conductor (about 20X more than snow!). Those shrubs can lead to a cooling of the permafrost in winter (thermal bridging by frozen branches) and a warming in spring (light/heat absorption by buried branches). ❄️ See our new study in @NatureGeosci

#DYK that the lemming plays a bigger role in the arctic ecosystem than the polar bear? Learn how climate change is affecting the Arctic’s smallest mammal. #Arcticmammal #arcticecosystem canada.ca/en/polar-knowl…
#DYK that #climatechange is making it harder for #lemmings to dig tunnels in the snow? Read tinyurl.com/3rhryuyc to find out why that’s a big deal in the #Arctic @universitelaval @MuseumofNature
1/2 #DYK that Lemmings are small mammals with a big influence on Arctic ecosystems? Most arctic predators eat lemmings.
I have the chance to be involve in this amazing multidisciplinary project! Check out our new paper about the challenges and design of a camera trap filming lemmings under the snow! 🐹🎥 @sentinelle_nord
By applying new solutions to their camera traps, these researchers obtained the first videos of lemmings under the snow during the Arctic winter! @cen_nord @universitelaval buff.ly/3dUJI7O
