A sneak peek of our winter campaign in the beautiful Canadian Arctic ❄️💧

This is really a stunning paper. Cyanobacteria exposed to shorter days (in the lab) "rewire" their membrane lipids to anticipate cold weather. When those cells are plunged into cold water, they have "two or three-times higher survival" than cells exposed to longer days.

Nature research paper: Carbon emissions from the 2023 Canadian wildfires

New paper published in @NatureComms The 2023 fire season in Canada is a wake-up call: severe climate impacts on fire activity are arriving decades earlier than predicted. Building fire-resilient environments is now more critical than ever! @NRCan @CEF_CFR

Un sujet qui en surprend plus d'un!

"More than 4.4 billion people in poorer countries lack safe drinking water, a number more than twice as high as some other estimates" Mapping safe drinking water use in low- and middle-income countries | Science https://t.co/MS8WrCHbgm

Our new paper led by @kevcrose makes the case that aquatic deoxygenation has sufficient implications for the Earth system that it warrants inclusion in the planetary boundaries framework.

Excellent review/synthesis... worth checking out. Drought as an emergent driver of ecological transformation in the twenty-first century

"Walkouts, petitions & tweets: how a grass-roots movement led by students, postdocs and tenured academics changed gov. policy on science funding." Better pay for those funded by our tri-agency council. Definitely a *BIG* win. But still inequalities & short-term vision for most.

Pour l’🩵 des lacs, nous souhaitons vous rappeler d’adopter de bonnes pratiques de nettoyage 🚿 des embarcations ⛵️🚤🚣⛴️et ainsi limiter 🛑 la propagation des espèces aquatiques envahissantes (EAE).

It shouldn't have come to this but good to see alternatives for Can students coming to QC-hopefully more solutions will arise, esp for internat stds. Thx @mcgillu for sending the msg that stds are *welcome* here. Awards (80% eligibility) offset '24 tuition increases to '23 levels

Today we are happy to announce the most recent winners of SIL's prestigious Naumann-Thienemann medal, awarded for a lifetime of outstanding scientific contributions to limnology research 💧 Please join us in congratulating Dr Vera Huszar! 🏅

There is a ton of misinformation in my replies so here is a primer on permafrost carbon. Permafrost stores a HUGE amount of carbon because ancient life took up CO2, built biomass, then died. That organic matter (~50% C) slowly accrued in Earth's best freezer for 1000s of yrs. 1/

🐟Traditional Inuit fishing sites are linked to Arctic char habitat use. A fantastic collaboration with fishers allowed to characterize winter habitats.

Why are our best and brightest leaving Canada? 🤔 Really proud of the @SupportOurSci team for being featured in this piece from @UA_magazine! Read more here 👇👇 https://t.co/i5CWw5OZBw #SupportOurScience

That rings a bell.

Freshwater ecosystems cover <1% of Earth's surface but hold >10% of all known species.

"Women feel driven out by problems with toxic workplace culture more often than by lack of work–life balance."

@NatureClimate widespread oxygen loss in warming rivers in US + Central Europe, at rates higher than oceans but lower than coastal & lakes. Urban rivers warm up fastest; agricultural rivers lose oxygen fastest https://t.co/7fhd2snmpG @LiReactiveWater @JiangtaoLiud @BOKU_HyWa

#FactFriday Did you know that graduate students holding a Tricouncil award like #NSERC and #SSHRC can't afford to live in a 1-bedroom apartment in the city they study in. How can we expect researchers to make advances in Science when they can't make rent? 😱 #SupportOurScience

In our paper in @NatureGeosci, we find increasing concentrations of soluble phosphorus across the Great lakes Basin. Greater increases at higher latitudes suggest warming winters to be a potential driver #ClimateChange #waterquality #machinelearning @GWFpubs @LakeFutures
