it’s #ToothyTuesday! some of my fav teeth are colugo lower incisors. these teeth are pectinate or “fan-like,” exhibiting many long, thin projections used for grooming! while colugos are sometimes called flying lemurs, they’re not actual lemurs: lemurs = primates, and colugos = dermopterans!

This image depicts the anterior, or front part, of the mandible, or lower jaw, of the colugo. The three incisors on each side of the jaw - especially the middle two teeth on each side of the jaw - are pectinate, or “fan-like” in form, with tooth crowns exhibiting many long, thin projections that colugos use for grooming.

I'm looking for PhD student to join my lab at the University of Arkansas at Little Rock (Fall 2027)! If you're interested in evolutionary genomics, conservation genetics, or biogeography, please reach out. I'll also be at #AOS2026 this week talking about sexual selection in small populations.

‘The Red Ghost’ This piece is based on a legend from Arizona that is both fantastic and partly factual. It’s too long to post here, but I absolutely recommend looking up the history of the US camel corps in the 1800s and The Red Ghost. I wanted to show both aspects of the story in this piece!

A red camel ghostly apparition with a golden skeletal rider in a starry Arizona desert setting. A more realistic camel with a skeleton tied to its back is silhouetted against the moon on a sand dune filled with camel skeletons, and a turkey vulture waiting off to the side.

Happy to see this out in early view in Evolution! We tested the roles of signaling and camouflage in the evolution of iris color in Tyranni songbirds. Our findings suggest that bright irises are social/sexual signals mostly associated with species less vulnerable to predation doi.org/10.1093/evol...

Evaluating the roles of signaling and camouflage in the evolution of iris color in Tyranni passerines

Abstract. Iris color is a conspicuous and diverse trait across animals, but its evolutionary drivers are poorly understood. In over 1000 species of Tyranni
