Check out how far back the tongue tip (gold sphere) reaches during swallowing in cane toads! What does this mean for our understanding of frog feeding? Read more about this cool behavior here: academic.oup.com/iob/article…

Beyond the party horn tongue 🥳🐸 @rmkeeffe and team x-rayed cane toads' feeding behavior to document the complex pulley system of cartilage and muscle that travels so far down their throat, it butts up against their heart.

I'm excited to share our recent publication in @iobjournal on feeding mechanics in toads! Think you know frog tongues? There is a lot more to them than meets the eye!

The Mayerl lab at @NAU is hiring! We're looking to recruit a graduate student and postdoc interested in #Physiology , #feeding , and #biomechanics. Check out the lab website or message for more christophermayerl.weebly.com…
New paper on the function of bone fusion in the frog forelimb (authored by myself and @davidcblackburn) is now open access in the Journal of Anatomy! Frog arms still have a lot to teach us about frog evolution, come check it out! doi.org/10.1111/joa.13737

A new study by @rmkeeffe + @davidcblackburn indicates the way frogs mate and fight may hold a missing clue to their mysterious skeletal evolution.

I am pleased to announce that I passed my PhD defense yesterday! Starting this fall I will be joining @sexinnature at Mount Holyoke College as a postdoc--I am so excited to work with Patty on her project investigating genital coevolution in snakes!
My defense seminar is happening this Friday at 12PM - 1PM EST! Tune in if you'd like to learn about why frog arms, tongues, and hyoids are so amazing!

Saw two juvenile diamondbacks over the weekend near St. Augustine--such gorgeous animals! Diamondbacks are one of the six venomous #snake species in FL. #herping #rattlesnake

Check out this fun article about the new burrowing frog paper @davidcblackburn and I published in @BiolJLinnSoc! Very fun working with @hallewrites @FloridaMuseum for this one.
Burrowing frogs may not look ripped, but their pecs have been honed by 200 million years of evolution. (Talk about reps!) We bring you the science of #RoundFrog anatomy & workout tips for getting the burrowing body of your dreams.

I'm excited to share some of the work I've been doing on burrowing frog pectoral anatomy! This paper includes a literature review of burrowing behavior in frogs as well as morphometrics of the humerus across all frog families.

A 29 million-year-old coquí fossil takes the title of the earliest Caribbean frog ever recorded. Fittingly, the fossil was found on the island where coquís are most beloved – Puerto Rico. 🇵🇷🐸🦴

Here it is, the oldest Caribbean frog! In this paper with coauthors @davidcblackburn @rmkeeffe & M.C. Vallejo-Pareja we describe a humerus of a #coquí frog (Eleutherodactylus) from the early #Oligocene of #PuertoRico! 1/6

New paper out in New Phytologist I wrote with @mcdaniellab and Jon Spoelhof of @soltislab on polyploid incidence in plants and animals. Was fun collaborating on a paper about such a broad group of organisms. nph.onlinelibrary.wiley.com/…
So glad to have been able to contribute to this project, what an incredible group of fishes! Take a look if you like cool life history strategies and kinematics #goby
