Hundreds of thousands of bats emerge from a large Mexican-free tailed colony in East Texas. The bats gave us a spectacular show with plenty of daylight left, emerging about 20 minutes before sunset 🦇

Second, our big effort to (1) make a new fish tree (2) date it (3) define taxon names (4) build the largest fish CT scan dataset to-date (5) answer ecomorphological questions- whew! @sternarchella.bsky.social @arciladk.bsky.social www.biorxiv.org/content/10.6...

New paper out today! @sternarchella.bsky.social and I review how modularity and integration influence adaptive radiations and diversification. Read it here: rdcu.be/fpcSX

Goby gummies? Yes, goby gummies. New lab paper out by @chemingson.bsky.social besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Twenty five years on from Dolph Schluter's book "The Ecology of Adaptive Radiation" that reshaped the way adaptive radiation was studied, this review revisits key questions raised to evaluate the progress made over the past quarter century, 8 of which remain unresolved...🌍🧪👇

‘The ecology of adaptive radiation’ revisited: A 25-year reflectionAbstract. Twenty-five years ago, the book The Ecology of Adaptive Radiation by Dolph Schluter presented a testable framework that integrated ecology, genetdoi.org

Peregrine falcon hunting bats (very successfully) in Houston tonight!

I'm glad that I wasn't a grandma for once and went to the division social because @sternarchella.bsky.social taught me that flat fish have handedness preferences (!!?!!) and that parrotfish beaks are a hellscape amalgamation of teeth. Fish are wild. I 🐟 #SICB2026

The K/Pg extinction created a buffet for open-ocean fishes. A new paper shows that Pelagiaria underwent an adaptive radiation following the extinction based on new jaw shapes to fill the vacuum @knapprew.bsky.social @evoswami.bsky.social @sternarchella.bsky.social academic.oup.com/evlett/advan...

New paper! Here we look at shape evolution of the mandible in Pelagiaria, a group of open-ocean fishes that includes tuna and mackerel. We find that shape disparity accumulated rapidly at the origin of the clade at around the K/Pg boundary... academic.oup.com/evlett/advan...

Adaptive radiation of pelagiarian fishes at the K/Pg boundary led to rapid diversification of mandible morphologyAbstract. Mandibles represent a key evolutionary innovation that has enabled jawed vertebrates to adapt and diversify in response to a range of food sourceacademic.oup.com

This paper has been in the works for a long time for various pandemicky and other reasons, and I thank all of my excellent coauthors for their hard work and patience! @evoswami.bsky.social @friedmanlab.bsky.social @sternarchella.bsky.social @gilespalaeo.bsky.social @gizehrdelazaro.bsky.social

MicroCT scan of crypt galls induced by the cynipid wasp Bassettia pallida in branches of the southern live oak, Quercus virginiana. Hiding in the crypts are a second parasitoid wasp, the crypt-keeper - Euderus set! @sternarchella.bsky.social #biodiversity

Stoplight Parrotfish, just a ridiculously beautiful animal. #scuba #diving #oceans 🦑

I love it when art and science connect! The newest art exhibit at Rice’s Moody Center features stunning representations of fish anatomy by @sternarchella.bsky.social and some of his students!

91 years is a good long run for most but too short for someone like Jane Goodall. Damn.

Jane Goodall, ethologist and conservationist, has died. She was 91

Thrilled to see our PNAS paper out! Such an amazing journey and couldn’t have asked for a better experience working with the Evans Lab 💙🐟

We have a new paper on the icefish adaptive radiation led by @mayaranevesbio.bsky.social, a new PI at UFPR 🧊🐟

Episode 62 launches this Friday! Join us as we chat with @sternarchella.bsky.social, Ichthyologist and professor of biosciences at Rice University. Dr. Evans chats with us about fish evolution, particularly through the lens of fish skulls. A fascinating discussion, fresh in your podcatcher Friday!

Wing pelage is suggested to have a functional role in bats — and it’s not just to make them cuter. Check out the publication below to learn more! #academia #academicSky #PhDSky #bats #science
