I am thrilled to share that the biology dept at Hamilton College is hiring a TT Evolutionary Ecologist to start in fall of 2027! This position would teach an upper level Evolution lect/lab, a section of Bio-100, rotate through our 200-level Eco/Evo course, and a seminar. apply.interfolio.com/190184

I feel so lucky to have great students, who are just as into frogs as I am. Check out this highlight featuring the work our lab is doing this summer ❤️🐸❤️ www.hamilton.edu/news/stories...

Fluorescently stained D. ochropheaus spermatophore! Heads are in red, rest of cell is green.

Please help us collect data on the experience of working at a PUI for our editorial!

Amazing visit at UF to collect amphibian testes from the Natural History museum and give a seminar. Met amazing people and met some amazing specimen. Lacking pics of people but here are some of my fav critters that I sampled! Special thanks to Dave Blackburn and Coleman Sheehy for all their help! 🐸

Super proud of Andrea! Check out her recent highlight of our lab for world frog day 🐸

Another beautiful testis specimen on the SEM! This time Leptodactylus boliviana. You can see the broad undulating membranes (the wavy bits) stacked together in the sperm bundles 🤯

Rhacophorus nigropalmatus testes sections from a museum specimen collected in 1980! The sperm have fantastic structural integrity after almost 50 years 🤯 Also, check out those curly sperm heads!

Nothing is better than a good night of herping! Spotted salamanders, wood frogs, spring peepers, green frogs, eastern spotted newts and redbacks all out and partying while the weather was warm.

Boy do I love phase images of salamander sperm 🌈 Pictured: Bolitoglossa peruviana

Highly recommend the Book of Frogs. It was an excellent read, and is accessible and interesting to folks at all levels! 🐸

It me.

Some beautiful TEMs of Rhinella marina flagella cross-sections! Axonemes on the left, connected with a membrane to axial fibers on the right (black teardrop shapes).

Love the photo booth at #SICB2026!

So proud of team frog sperm representing at #SICB2026! 🐸

Off to #SICB2026! Come check out the work from my lab: Sun at 11am (202)- My talk about the evolution of amphibian sperm Tues poster session - two posters about green frog sperm performance in egg water presented by my awesome students! See you there! 🐸 ⚫〰️

Our first TEMs of frog sperm rolling in! This species of Chiromantis has a flagellum with two axonemes surrounded by microtubles. Frogs are so weird! 🐸

A side quest/future project of mine is to figure out what the axial fiber in amphibian sperm tails is made of. Maybe the same material that makes up the fibrous sheath of mammal sperm? These SEMs show an intact cell and one where the cell membrane is lost revealing the protein structure of the fiber

Another highlight of Max and Charlotte's project! 🐸
