Meet Salwasiren qatarensis, the most complete dugongine yet from Qatar. Just published this week. #FossilFriday. Read it here: peerj.com/articles/200...

Discoveries reveal Arabian Gulf hosts both ancient fossil bed containing newly identified sea cow species and world’s largest living dugong herd Two new studies co-authored by a Texas A&M at Galveston biologist reveal Qatar as a 20-million-year hot spot for dugongs past and present.

EcoMorphLab publications! A pair of dugong papers out of Qatar highlights the discovery of a new 21 million old sea cow and new data on large aggregations of modern dugongs in the area. Check out the Texas A&M Press release summarizing both!.

Bluesky’s logo, a trusted verifier’s scalloped checkmark, and a standard verified blue check mark.

We’re introducing a new layer of verification on Bluesky — a user-friendly, easily recognizable blue check.

In addition to account verification issued by Bluesky, we're also introducing Trusted Verifiers. Select independent organizations can verify accounts directly.

As a curator at a natural history museum, I'm gutted to learn about the dismantling of the Institute of Museum and Library Services. If anything, we need to fund, protect and preserve museum collections and uphold institutions of scientific and cultural knowledge now more than ever.

Cool New 🐢 paper: Using three decades of satellite tracking date, Briscoe et al show how loggerheads in the North Pacific have shifted North 🌍🧪🦤 www.frontiersin.org/journals/mar...

Same. That is an impressive dissection.

Great list. Thx for adding the GCSTR. Pls add @ecomorphlab.bsky.social too

A cute little porcelain crab. The crab is orange/red with lots of white spots ringed in red all over its body.

The spotted porcelain crab, Porcellana sayana, which often lives as a #commensal inside of the shell of the giant red hermit crab, Petrochirus diogenes. That is excactly where I found this one hanging out in Tampa, FL. #crustmas #invertebrate

Tip for writers, especially academics . . .

Do sharks exhibit heterodonty by tooth position and over ontogeny? A comparison using elliptic Fourier analysis Ontogenetic changes in morphology are limited in bull sharks and do not occur in blacktip and bonnethead sharks. Heterodonty is ubiquitous within the jaws of each species. Significant interspecific d....

Our new work in ecomechanics using sharks to integrate trophic ecology w bite performance (Front in Mar Sci) builds upon past work on shark tooth morphology published in JMorph. Check out both.

Not a new paper, but still helps (1/2)

For science 🤓 folks. @bsky.app is now included in @altmetric.com scores for papers and is demonstrating good levels of engagement on publications (sent from @jadeunderwater.bsky.social ) 🐢🌍🧪🦑 🐟🐠🐡🌐🦤

Excellent new #OpenAccess paper by Holly Stokes and others demonstratng lack of negative impacts of satellite tracking of juvenile hawksbill turtles. Important insights from long term work. More studies appraising impacts needed 🐢🌍🧪🦑 🌐🦤

I like how you roll. I think about pinniped teeth and sea turtle beaks. Why reduce mastication or give up your teeth?

What a great resource for teaching #comparativeanatomy!

Testing and Masking Policies and Hospital-Onset Respiratory Viral Infections This cohort study examines the ratio between hospital- and community-onset respiratory viral infections at different levels of testing and masking from 2020 to 2024.

Most hospitals have dropped masking & #SARSCoV2 testing requirements. But after 10 Boston hospitals ended both precautions a surge in hospital-onset viral infections ensued. Just resuming masks—for healthcare workers only—lowered rates of respiratory infections by 33% jamanetwork.com/journals/jam...

Congrats to our newest PhD student, Justin Jenkins, on wrapping up his first semester as a graduate student. Justin will be investigation the trophic ecology of Galveston Bay sea turtles. Welcome aboard.

Congrats to doctoral student Theresa Morris. Her grant to “Develop[ing] Molecular Tools for Demographics and Distribution of Galveston Bay Estuary System Sea Turtles” was funded by Galveston Bay Estuary Program this month.

Congrats to now doctoral candidate Madelyn Rupp @seaturtlecenter.bsky.social and @ecomorphlab.bsky.social for passing her qualifying exams this month.

This week I was honored to receive the Regents Professor Award- the highest honor bestowed by @TAMU to faculty.

Thx to colleagues, students, staff, & volunteers that, over the years, were a part in making this possible. I owe each of you a debt of gratitude!

A pleasant Thanksgiving surprise . Our work on shark ecomechanics, which integrates bite performance with trophic ecology using stable isotopes, was officially published - a solid ecomorphological piece of work.
