Amanda Sabatino, @jpjahner.bsky.social and I have a new paper on @biorxiv-evobio.bsky.social. Amanda, in her undergraduate thesis work, found variation in Colias colour phenotypes is associated with different metrics of urbanization in Toronto. www.biorxiv.org/content/10.1...
Anthropogenic factors explain wing colour variation in Colias (Lepidoptera: Pieridae) butterflies across the Toronto urbanization gradient
Hybridization, or interbreeding between two previously diverged populations, is increasing due to human influences on the environment. Rates of hybridization might be increasing particularly quickly a...

My car cloned itself while I was at work! But I’m confused as an evolutionary biologist bc I thought only hybrids did that, and it’s electric! Is my car a plant? Was it parthenogenesis, gynogenesis, or kleptogenesis? Mysteries abound!

Very cool! The more we learn about the biology of sex determination, the more interesting and complicated it gets. (I rescind my previous snarky comments that birds are "simple and boring" in this department.)
Newest lab research:
Up to 6% of the wild birds - in all 5 species we looked at - showed a different sex morphology than what their blood tests (read: chromosomes) told us. Sex is not simple!

Today the air quality index where I live is 168 due to drifting smoke from wildfires. I canceled my trail run. My kid is mad at me for not letting her attend soccer camp, but really, we should all be mad at our leaders. We need climate science and clean energy policies, not cuts.

It's easy! Save their numbers in your phone and make calling a habit. Call the ones you agree with and the ones you don't - positive feedback when they do the right thing is just as important as critical feedback when they're doing something you don't like.

Michiganders, I just called my Republican congressional representative to express my opposition to the budget bill, and got right through to a staffer. That's not right, his phone should be ringing constantly. If you're in the UP, represented by Bergman, and oppose the budget bill, give him a call!

The USGS coop units are so essential to fish and wildlife management/conservation. I have been so lucky to work with these talented and dedicated researchers over the years, and am beyond sad and infuriated about these proposed cuts.
Fate of Wyoming Cooperative Fish and Wildlife Research Unit staffers — Matt Kauffman, Anna Chalfoun and Annika Walters — remains unclear, but Trump administration cuts have led to widespread suspicion that their days on the job are numbered.
