Asexual Amazon mollies differ morphologically from their sexual hosts, resembling P. mexicana when coexisting with P. latipinna hosts, and vice versa! royalsocietypublishing.org/doi/10.1098/...

The desert sun is relentless even in December. But at least there are still fish around!

So many bird pictures in my feed… So, here are some impressions from our grotto sculpin fieldwork last month. This curious little species is endemic to a couple of caves in Perry County, Missouri.

The RFP for #PRFB is out again. If you are interested in developing a postdoc research project in the realms of (extremophile) fish biology, evolutionary ecology/genomics, and/or conservation, shoot me a message. St. Louis is an awesome place to live and do science!

A wild week surveying the endangered inhabitants of springs, sinkholes, and wetlands in the Chihuahuan desert. We had an awesome team working through 70 sites; ready to return in the fall!

As I’m gearing up for another week in the field, I’m still digesting our recent visit to Mexico. So many good memories with a great team. But seeing the same sites for 20 years, there was also a brutal reality of a changing climate and human activities encroaching on the last bits of wilderness…

Look at this spectacular Corynopoma. It's not the exaggerated fins that make these swordtail characins so awesome, but if you look closely, you can see a filamentous extension of the operculum with a knobby tip. That thing mimics ants, is displayed during courtship, and makes males look extra sexy!
