Now out in the September issue of @journal-evo.bsky.social!

- Pop-level thresholds between male/female development (Tpiv) correlate with mean incubation temps among species, but temp variability within species

- Threshold variation within pops (TRT) is more complex and confounded by study design

Attention graduate students! The Orianne Society’s Grant Program for Reptile and Amphibian Conservation in the Southeast is now accepting applications.

Despite how often I’ve had a spotted turtle retract its head and thought “Wow, that thing is really tucked away!”, I somehow don’t have a picture of it to share. But apparently that neck skin has evolved to be thick and protective and now it has a name: the clemmysian fold!

A wee thing helped across the road today. I think this is the smallest wild box turtle I’ve ever seen - just hatched last fall!

Haven’t practiced photography in a while, but Mooney was a cooperative enough model while I quickly reminded myself how a flash works

Hey #JMIH2025, interested in temperature-dependent sex determination? Come to my talk at 1:30 today, right at the beginning of session 18!

Proofs are up for my latest pub in @journal-evo.bsky.social! It’s a big ol’ analysis of how sex-ratio reaction norms vary with local climates within and among turtle species with TSD. Check it out here:

Nothing hits quite like finding a new population of these guys

The duality of turtles

I’ve only played a small role, but I’m excited to be a part of the revamped Tree of Sex group and to see what’s coming!

🚨 Cool new project alert 🚨

WE- you, me, everyone- need to work together to get important science messages out to people.

4 artists & 3 scientists collab'd on these posters. We hope YOU will put them out in your community. Each poster comes w/info about each topic.

New research from our lab exploring the ecological consequences of behavioral syndromes! @morganichemistry.bsky.social shows that antipredator behavior in painted turtles is repeatable and associated with ecologically significant variation in nest site choice.

Crazy times, but I'll be advertising for a 2 year postdoc to work with me on new comp. methods to estimate evolutionary history soon - specifically to develop methods to handle missing data (e.g. ascertainment bias, allele dropout). Are you a comp. biologist graduating with a PhD soon? Reach out!

We’ve reached new records of small in the field recently

One of the biggest and one of the smallest Blanding’s I’ve caught so far! The big one has about 2 decades on the small one

Bumper day for Blanding’s

Today was for 20+ year old Blanding’s

I know it’s field season when my camera roll starts to look like this:

It snowed this morning, but 35 degree water won’t stop spotted turtles from making more spotted turtles!
