Probably cold tolerance, but maybe also flight endurance.

Snowfinches actually had a totally different phenotype than high-elevation sparrows, with more capillaries in their heart to enhance oxygen supply.

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

This week, we are also highlighting Carol Bucking, who recently co-edited @jexpbiol.bsky.social Special Issue: The Integrative Biology of the Gut, as an extraordinary biologist. #100biologists ‪

Thank you NSERC for providing me funding to start my research!

New paper shows that cardiovascular adaptations to high elevation in birds depend on evolutionary time at high altitude. It was great being part of this collaboration with Yanhua Qu, Huishing She, and others at Chinese Academy of Sciences. academic.oup.com/mbe/article/...

Congrats to Ranim Saleem from the Scott Lab for winning best physiology poster at the @csz-sczofficial.bsky.social meeting for her work on mitochondrial adaptations to high altitude.

Are you searching for a postdoc in Saskatchewan? I have a 1-year opportunity (with possible extension), effective immediately! This opportunity is a Mitacs Elevate with the Canadian Prairies Prescribed Fire Exchange! Reach out if you're interested! 🐦🔥

Do you like songbirds? Are you concerned about how wildfire smoke may impact their physiology?

I'm searching for graduate students who are interested in looking at the effect of wildfire smoke on songbird physiology! Come join my lab @usaskartsci.bsky.social!

The Scott Lab at McMaster is currently recruiting graduate students to examine the physiological and molecular mechanisms of high-altitude adaptation in small mammals. Details at scottlab.ca/opportunities/

Congrats to Emily Choy for being awarded the King Charles III Coronation Medal for her research! Great to have her as a colleague @mcmasteruniversity.bsky.social

I'm looking for a post doc to work on the effects of CO2 and diet on lake whitefish growth and physiology in collaboration with Dr David Huyben. Term 12 months, salary 60k CAD. More info here utsc.utoronto.ca/biosci/emplo.... Deadline May 18! @utscbiology.bsky.social

The time has come once again where we put out the request for donations for the 2025 CSZ-SCZ Silent Auction. All funds obtained go towards supporting the student section.

There is still time to apply for this position! Great fit for students interested in combining evolutionary and eco-physiology theory to find solutions that promote pollinators in a warming world. Please distribute in your networks. Details 👇 🐝🦟 ☀️🌡

For Women's History Month, may we all remember and summon the courage of Rachel Carson, who wrote Silent Spring to inform the world what DDT was doing to the songbirds, raptors,and by extension, us. While battling cancer, she stood her ground against savage attacks by the chemical industry...

Honouring Lulu Gaiser, trailblazing biologist who in 1925 became the first woman to join the faculty at McMaster. science.mcmaster.ca/ahead-by-a-c...

I contributed to this deep dive by @ljevanso.bsky.social on the long road to gender equity in the 🇨🇦 academy. Worth a read! universityaffairs.ca/features/the...
