We now have a starter pack for the Tree of Sex consortium! Interested in reproduction (not just sex) in eukaryotes? Get involved!

Many thanks to @ajmongue.bsky.social for putting this together!
As work ramps up, we've created a Starter pack to follow members of the consortium.

Fellow Europeans, it's time to move away from using American technology and software. Using European and open source alternatives makes us more sovereign and safe, and reduces the influence of Trump-supporting technology oligarchy.

Here's a good guide for finding European alternatives.

If you're interested in the evolution of sex determination, check out this opinion piece from Tom Kocher, @tonygamble.bsky.social , @behrenskristen.bsky.social , Will Gammerdinger, and me. We argue that genetic variation in sex determination is probably more prevalent that most people think.
Yes, polygenic sex determination is a thing!
The process of sexual development in animals is modulated by a variety of mechanisms. Some species respond to environmental cues, while, in others, sex determination is thought to be controlled by a s...

There are a lot of new people here, so I've set up a starter pack on Mating Systems, including sexual selection and conflict, sex differences and determination. Let me know if you want to be added! go.bsky.app/QXrYoQY

Genetics Starter Pack 2
Some accounts I can’t believe I missed the first time, self-nominees, and recent arrivals. If I still missed you, I’m probably sorry. Maybe you can post starter pack 3.

Let us be clear: This is a fraught moment, and one that has polarized not only Americans but people all over the world. It demands incredible sensitivity and strict adherence to journalistic standards of objectivity, and simply put, that is something we aren’t willing to do.

Our Dept is hiring two TT faculty positions. Very broad search that has been delineated into two positions. I'm on both committees, happy to answer questions.
