πŸ“£ πŸ“£ Calling genomics-y and ecology friends, three permanent faculty positions at @monashbiol.bsky.social in Melbourne, Australia! See job listings here.

Extremely excited to share I have accepted an offer to be an Assistant Professor in the MCDB department at the University of Michigan! Go Blue! The Ledvina lab will investigate the molecular interworking of the bacterial immune systems including defense against both viral and bacterial pathogens.

Evolution of endothermy in marine fishes is related to competition with cetaceans. This incredible paper is a masterpiece of phylogenetic comparative methods and a future classic for marine biologists www.science.org/doi/10.1126/...

#Evol2025 was for me maybe the most important meeting I have ever been to. My science will be drastically improved by my interactions over the past week. It was bittersweet due to the current situation and the people who weren't there, but I'm optimistic that we are strong enough to overcome this.

Another day testing the limits of resilience. The Alexandria NSF building was designed for the NSF merit review process (gold standard), complete with a floor devoted to panels. Now we aren’t allowed to have in person panels. The loss of US science leadership will haunt this country for decades.

I am thrilled to announce that in January 2026 I will be starting my own lab at NYU Biology! Soon enough I will be recruiting postdocs and students! Please reach out if you are interested with a CV and description of your research interests, or if you know of people who could be interested! πŸ§¬πŸ—½ 🦊

With news of court-ordered #NIH grant reinstatements, and rumors of changes to termination policy, we're trying to get a handle on what is actually happening to PIs. Your reports are the best info we have! Please submit reports of *reinstatements* to grant-watch.us as well as terminations.

Had a blast at #Evol2025. It was an honor to present my research on the endangered scrub mint, Conradina glabra, to so many brilliant scientists. A lot has happened in the years since my first conference poster!

I had the pleasure of presenting my poster at #Evol2025. Special thanks to my mentors Ricardo Azevedo @ricardoazevedo.bsky.social, Becky Zufall @rebeccazufall.bsky.social and everyone who came by!

Want to watch my Presidential Address from #Evol2025 where I share who I have learned from, how I hope to pay it forward, what I have learned from studying ants, and how it is all of our responsibility to create equitable and just futures for everyone? Watch here: www.youtube.com/live/vkBD3fg...

The 500 additional GRFPs NSF awarded were not very evenly distributed across fields, it seems. www.science.org/content/arti...

My kid on useful expressions he’s learning: β€œno pinto nada aquΓ­ - this isn’t for me, i’m out of place here (think of dada at a party)”

Had an amazing time at #Evolution2025 β€” Grateful for the chance to share my work on how phenological shifts are impacting plant fitness. Until next time! #Evol2025

#Evol2025 was such an amazing experience! I presented my work on sexual differentiation in Silene acaulis, watched my science heroes present their work, and connected with others working on similar questions. I feel fortunate to be surrounded by an amazing group of supportive and brilliant people!

Ethical scientific journals and where to find them....here is DAFNEE, a #database of non-profit journals in #Ecology and #Evolution #EvoBio, to choose an ethical place where to publish your next articles! (1/2) dafnee.isem-evolution.fr πŸ§ͺ #science

Huge LSU crew at Evolution! We don't know where the tiger came from πŸ˜‚ (seriously we don't)

Phylosignal celebrates its 500 citations! πŸ“¦πŸŽ‰ I've written a short blog post to celebrate and reflect on this 10-year old #rstats project. πŸ‘¨β€πŸ’» www.pieceofk.fr/phylosignal-...

11 years ago today, I was at the super social at my 3rd Evolution conference, at the Natural History Museum in Raleigh, NC. Today, I was at the super social at my 3rd meeting as one of the organizers of the conference, at the botanical gardens in Athens, GA. Gratuitous old pic:

NSF to be booted from office space but also required to work in person? www.alxnow.com/2025/06/24/r...

If you were at #evol2025, *this* is why every conversation you found yourself in had someone from LSU! We roll deep. Join us in Baton Rouge in January for the @systbiol.bsky.social breakout meeting! Equally good science conversation, just add gumbo and king cake.

FYI if anyone else at #Evol2025 will be driving home through Atlanta today -- I-20W is currently closed through downtown due to a fatal crash (according to local news) around 3AM but no idea when it will reopen. Godspeed 🫑

& that's a wrap for #Evol2025 ! Thank you to everyone who came to show your support and give constructive feedback for dusti 🐌 It was amazing meeting so many outstanding biologists in the field of evolutionary biology the past few days!

In multiple discussions of biggest take-away from #Evol2025, I keep coming back to @corlettwood.bsky.social’s talk about how rhizobia affect Medicago trichome number (herbivore defense) in the opposite direction of what I’d expect

Now THIS was a beautiful, fun, and memorable super social! Absolutely stunning garden and conservatory - worth dealing with the heat. πŸ₯΅ What a great way to close out a great conference. #Evol2025

Just want to point out here that many departments with low enrollments are considered "service" departments. For example: at a lot of schools, most students in chemistry classes are biology majors (often with a pre-health focus), or nursing students.

NEW: NSF will be kicked out of their building. Announcement will be made tomorrow by HUD Sec. and Governor of VA. HUD will take over the NSF building over the next two years. NSF staffer: "There is no planning for NSF, no identified future location, appropriation for a new building or a move."

Successful first #Evol2025 with @gbaucom.bsky.social lab! Shout out to @inam-j.bsky.social and @gmzhang.bsky.social who presented great talks and my cohort member Emma Foster who presented a poster of her newest review paper!

Great running trails in Athens, Georgia, for #Evol2025! πŸƒπŸƒβ€β™€οΈπŸƒβ€β™‚οΈ @runnersworld.bsky.social

Thanks @LSU folks! Higher quality photo coming soon! #Evol2025

Very sad to learn Richard Bambach has passed away. In addition to his significant contributions to science and the 'paleobiological revolution', I will mostly remember him as a warm and wonderful presence in our paleobiology journal club when I was a postdoc at the Smithsonian

Amazing #Evol2025 ! New friends on Bluesky 🌌 Stunning science 🧬 Heartfelt rally calls πŸ“£ Hope in the face of adversity πŸ«‚ But... I will not miss the jingle jangle of those darn badges πŸ”•
