Very excited for this incredible lineup of talks at #SSB2026! ssb2026.github.io/talks.html For those giving talks, more instructions will be sent shortly. @systbiol.bsky.social

We have 526 scientists signed up for spring semester. We try to get that to about 1000 scientists before unleashing the teachers on the database. Wanna connect a class of kids with science this spring? Sign up!

We're editing a special issue of Ibis and are after the best in collections-based research and commentary! All the usual Ibis paper formats are welcome (reviews, viewpoints, research articles, short communications). #ornithology #museums #birds

I started getting reports of an unseasonal Joshua tree bloom in the last few weeks, and looking over records on @inaturalist.bsky.social it's pretty widespread! So we're putting out the call for folks to record this "bonus bloom" and help us study it 🌿 lab.jbyoder.org/2025/12/10/w...

Looking for an *L.A. based* artist who (against all odds) has time for a poster gig before the end of the year. It's for a science + art event. We can offer $500 for the gig. Dreadfully sorry about the timeline. Link a portfolio if you're interested, I'll delete this post when we found someone.

Thrilled to share that @corriemoreau.bsky.social and I have a new paper out in Evolution, digging into the varied ways that extreme worker plasticity impacts genome evolution in turtle ants! Paper 📃: doi.org/10.1093/evol... Image 📸: Steven Wang, tinyurl.com/2rbjbyjh

For this month’s @outsidemag.bsky.social column, I took a rat taxidermy class, and it was… surprisingly sweet? As the teacher said, “We’re reclaiming what’s beautiful and interesting about the things we’ve been told are bad or gross.” I love my rat. His name is Meatball.

Check out our review/perspective piece on phylogenetic diversification analysis, intended for the 75th anniversary of @systbiol.bsky.social. I had the privilege of working with great coauthors, @fhenaodiaz.bsky.social, @tvasconcelos.bsky.social and @roszenil.bsky.social! doi.org/10.1093/sysb...

This is such a neat story!

Please apply to the ASN student research awards! This is such an amazing opportunity to get experience grant writing as a grad student, and the $$$ has funded some really fantastic research!!!

I know there are many worthy places to give, but if you're looking for a place to donate, @mammalogists.bsky.social is fundraising for a new award that honors Dr. Ralph Eckerlin to support students studying mammal parasites. You can donate to that fund (and others) here: asm.wildapricot.org/Donate

Looking for input on rodenticide testing . . . Colleagues are using a lab that needs 1 gram of liver sample to test, but often has specimens with less than that. Does anyone know if that amount of sample is really needed and/or have leads on labs that might be able to work with less? 🧪

Successful cleanout so far--half these shirts are gone! Thanks to everyone who has helped support my rebuilding efforts!

Here I am. Once again. I'm out of archaeologists. We matched 576 groups w/archaeologists, leaving 13 groups unmatched. This brings me pain! We've never run out of scientists like this before. 598 requests for one category is A LOT. But still. Archaeologists 🥺 www.skypeascientist.com/sign-up.html

74 students and 48 mentors have signed up so far! We can accommodate more of both groups. Student sign-up link is in the first comment.
