Nobody: what is a tree, anyway? Us:  authors.elsevier.com/sd/article/S... (Review out today, in which we ask whether xylem disconnection arising early in wood anatomy is convergent with disconnection seen across tall plants and whether tree evolution requires disconnection given periodic drought.)

Sorcery!

Bonellia viridis is a spoon worm where the female is a fat green blob and the male is microscopic and lives inside her. Sex is decided by luck: larvae that land on a female become male, larvae that land on bare mud become female. Mud determines your sex. #WormWednesday #marinelife

The strangest thing happened today. We went to the uninhabited island of Lunga, west of Mull, to look at the puffins nesting there. I was just taking photos when I felt a thump as something landed quite heavily in my head. It was a puffin! It stayed for about a minute before flying off.

What if some biological #traits are both one & many? 🤔 📄In our forthcoming paper @philsci.bsky.social, we show why recognizing composite traits matters for evolutionary inquiry & highlight the challenges they pose for #comparativebiology Preprint: philsci-archive.pitt.edu/30388/ #philbio #philsky

"A.i." for education is for cheating. That's its primary use case. Anyone who's pushing for "A.i." in education is pushing for fraud.

absolutely insane story, and yeah, just looking at this chart... with the exception of maybe two people, this entire class was cheating like motherfuckers

This puzzle is in my first book (the one no one reads), and I know Claude ate my books (bc I got part of that copyright settlement against Anthropic), so here's Claude's answer, from my book. The whole chapter is about this puzzle basically, builds answer using covariance genetics.

Leaf size is an important trait shaping species distributions globally. We looked at how climate and evolutionary history influence leaf size in conifers! Spoiler: lots of evolutionary conservatism!

Getting ridiculed for earning a PhD after a BA and Masters is a third degree burn.

Thrilled to share that my first dissertation chapter is now published at Ecology! dx.doi.org/10.1002/ecy.... We embed TPCs into population dynamics to show how changing temperatures' ordering — not just its distribution — increases extinction risk (i.e. heatwaves matter!) @esajournals.bsky.social

I just don't think there's such a thing as a "necessary" cookie.

I've been documenting a pair of black-capped chickadees nesting in our garden as they fly back & forth every few minutes, hunting meals. An avg clutch of 6 to 8 chickadees requires 3,000 to 5,000 feedings over the ~16 days from hatching to fledging. Most popular foods: caterpillars, moths, spiders.
