I'm so excited to share my master's research! Do pollinators change their foraging behavior depending on floral and ambient temperatures? Do flowers that thermoregulate experience higher rates of pollinator visitation? Check it out below! 🏵️

Schematic of how we measured live clingfish suction performance in a water tunnel with pressure transducers

In @fishguy.bsky.social’s lab we have done many studies on the suction cups of dead clingfish. In this new paper, @fishyologist.bsky.social et al and I found that clingfish can control their suction and stick harder than dead ones! @sicbjournals.bsky.social 🐟 🧪

New fish paper! We found that Clinocottus globicpes eats anemones (weird!) using a novel wrestling behavior + strong jaws that likely started as adaptations for tearing algae. It also has thick skin that protects it from stinging cells. @jzoology.bsky.social 🐟🧪

Incompatibility between two major innovations shaped the diversification of fish feeding mechanisms Large teeth and highly protrusible jaws are two feeding innovations that have evolved in fishes. High-speed videography and comparative phylogenetic analyses indicate that they are incompatible with e...

Out today in @plosbiology.org! We show that two major advances in fish feeding - highly protrusible jaws and large teeth - are functionally and evolutionarily incompatible with each other. @mikemihalitsis.bsky.social and Peter Wainwright. Free to read: journals.plos.org/plosbiology/...

I'm defending my dissertation next week, Monday June 30th at 10 AM ET. DM for a zoom link if interested!

Thanks Peter! Spoiler alert: no blenny teeth used, but blennies are still the best 😎

Thanks Emily! 🐟

Finally, a special shout out to all the museums that loaned specimens used in this study: @bellmuseum.bsky.social, Etnier Ichthyological Collection at UT Knoxville, Field Museum, Harvard Museum of Comparative Zoology, and Yale Peabody Museum. Now more than ever, #MuseumsMatter #CollectionsMatter

@evovert.bsky.social and I provide an open-source workflow and best-practices guide for quantifying tooth surface complexity in fishes. If you’re into microCT methods, fishes, or teeth, this paper is for you. 📊🐠🦷
