Exciting news! @wcratcliff.bsky.social and I published an essay last week in @nature.com reviewing the substantial contributions of 'long-term' studies to evolutionary biology

Please repost! We are looking for two field technicians to work on our deer mouse project in the Colorado Rockies this spring-fall. Learn about physiology, ecology, and evolution, all in one project! Not to mention that you get to be in the ⛰️. Reach out if you have any questions.

all right Marius! great job leading this v cool effort to test ideas about elevational migration at global scale
Why is there such variation in the birds encountered as you go up or down a mountain? New paper in #ScienceAdvances examines how climate and ecological interactions drive bird distributions in mountains throughout the year:

Climate, ecological dynamics, and the seasonal distribution of birds in mountains
Ecological dynamics related to energy use and competition drives the seasonal distribution of birds in mountains across the world.

why do males defend territories in some species while pairs or family groups defend territories in others?
then-undergrad Shreyas Arashanapalli did a fantastic project to find out, analyzing 3177 playback experiments on 264 species
the best predictor?

*walking around campus* Wow look at those distichous leaves...reminds me of 🦎Anolis distichus. I mean...leaf venation. Huh lizards have veins. Wait. No. Plants. Chlorophyll is cool...why do no lizards photosynthesize? Plants probably blocked them. Yeh, that makes sense. Should write a paper.

New paper out - fun collaboration with @wcratcliff.bsky.social & led by the wonderful Tony Burnetti! IMO, a rare clear example identifying the mechanism underlying priority effects at macroevolutionary scales. Also, continuing to justify my PhD from a plant lab 🍃

New paper out! Here's a puzzle: phototrophy, the ability to use light for energy, is one of life's great innovations. It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects.
