A mouse that lives higher than any other mammal has evolved unexpected adaptations that allow it to thrive from sea level to Andean summits, researchers report in a new Science study. Learn more: https://scim.ag/4bzjqWY

Adaptation across an extreme elevational gradient in Andean leaf-eared mice, the world’s highest-dwelling mammal

Andean leaf-eared mice (Phyllotis vaccarum) live at the highest elevations of any mammal, and they also have the broadest elevational range, from sea level to mountain summits of >6700 meters. Highlan...

Excited to share our new paper in @science.org on Andean leaf-eared mice, the world’s highest-dwelling mammal. It’s a fun and exciting project to be part of with a great team of collaborators!

My latest for CBC News: “At the top of a 6,739-metre Andean volcano, where the air is thin, temperatures are almost always below freezing and humans struggle to survive, a tiny leaf-eared mouse has made itself at home — dining on toxic plants.” #scicomm #sciencenews #evolution

Check out the new articles posted in our special issue, The Integrative Biology of Exercise, drawing on work in vertebrates and invertebrates to illustrate the plasticity or evolutionary changes necessary for exercise or sustained locomotion journals.biologists.com/jeb/issue/22...

New review article from the lab! In addition to discussing relatively easily studied hovering animals (hummingbirds, nectar bats), we call for further work studying energetics/fuel use in other nectar and fruit-feeders! With @giuliarossi.bsky.social @utscbiology.bsky.social @utsc.utoronto.ca 🦇🧪

Journal of Experimental Biology@jexpbiol.bsky.social · 4mo ago

Hummingbirds and nectar bats sustain hovering flight using sugar as a fuel source. In their SI Review, Welch & Rossi discuss the convergent and divergent mechanisms that these animals use to fuel this energetically costly mode of flight doi.org/10.1242/jeb....

Oxygen-free metabolism in the bird inner retina supported by the pecten - Nature

While the photoreceptor outer segments in the bird outer retina have access to oxygen, the inner retina operates under chronic anoxia, supported by anaerobic glycolysis in the retinal neurons.

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 ‪
