Applications for the ASIH Raney Fund are due in 10 days! Please spread the word if you know a student that could use funding for fishy research. I'm chairing the committee for the awards this year and am happy to answer any questions about it

I am thrilled to share that I have accepted an offer for Assistant Curator of Fishes at the Sam Noble Museum/Assistant Professor at University of Oklahoma!

I will be starting this August and looking forward to more fishy research. 🐟🐠🐡

Thanks to all who've helped me get this far!

I don't think people fully appreciate how apocalyptic things are for US science. I haven't had any new funding since 2024, but I'm still ok since typical grants are for three years. This means next year I will be completely out of funding and will have to fire everyone in the lab. It's not great.

I have been tasked with creating an evolutionary biology course. I was wondering if anyone has done the same recently, and has advice. Thank you.

Are you a student who wants to visit the NHMLA for your research? Do you advise or know a student who would benefit from visiting our collections? Well, there are three weeks left to apply for the NHMLA Student Collections Award. Help spread the word!

Habitat and complex life cycles promote morphological diversity in salamander limb bones We examined the external shape and cross-sectional morphology of limb bones in 133 salamander species spanning the ecological and phylogenetic breadth of Caudata. We find that adaptations for aquatic...

Second PhD paper is out! We find: 1) aquatic and terrestrial salamanders have different limb bone adaptations, 2) complex life cycles promote different traits, 3) decoupling of external and internal bone traits increase diversity.

Summer courses at Friday Harbor Labs have launched many scientific careers. Including mine. I was more reluctant to leave at the end of the course than other students.

I promise you will have fun and learn more than you can imagine.

I’m delighted to share my first ever book chapter is out now!
I goal with this piece is to provide a detailed but approachable review of ray-finned fish brain anatomy, anatomical diversity and evolutionary patterns.

Fossil evidence for trait diversification in an adaptive radiation - Scientific Reports Adaptive radiation is an important process for the origin of functional and ecological biodiversity. Understanding how, when, and why adaptive radiations occur is a long-standing interest in evolution...

Using fish teeth fossils from lake sediments, we found the haplochromine cichlids diversified quite rapidly and the entire food web evolved within just the first three millennia after the formation of modern Lake Victoria (which started refilling ~ 17k years ago). www.nature.com/articles/s41...

This is figure 1, which shows a three-dimensional rendering of Chamaeleo calyptratus Chamaeleonidae (UF: Herp: 191369).

A paper in Scientific Reports shows that chameleons have evolved a longer, coiled optic nerve that is likely to provide “slack” to reduce tension on the optic nerve during the extensive rotations characteristic of the chameleon eye. go.nature.com/3JTSgQ1 #evosky 🧪
