DeMarchi et al (2025) explore why some amphibians are better reservoirs for the deadly chytrid fungus (Batrachochytrium dendrobatidis, Bd) than others. See what they found at AmphibiaWeb.org #AWNews

Super proud of @stancaf.bsky.social and @shubhamsoni.bsky.social for having led this important Natural History study. Surely you have heard about arboreal ๐Ÿ, but did you ever imagine them to dive to hunt for tadpoles in treeholes?! You're welcome! ๐Ÿ‘‰ doi.org/10.1002/ece3...

Hey y'all. I'm a month late to this, but I wanted to share that one of my PhD chapters was published in Systematic Biology with my advisor, Frank Burbrink. Here, we explore how ecological opportunity influences phenotypic evolution in North American natricid snakes. ๐Ÿงต/8

Do tadpoles have acoustic communication? Protรกzio et al. (2025) documented Ceratophrys joazeirensis (Caatinga Horned Frog) tadpoles producing a short, metallic click sound. See what their hypotheses are for this observation at AmphbiaWeb.org #AWNews

Cartoon of Pax9 expression (purple) during facial development in mouse (left) and zebrafish (right).
Text: Mammals. Pax9 is expressed In tooth-forming mesenchyme around the mouth. Required for tooth formation in mouse and human.
Fish. Pax9 is also expressed in oral mesenchyme in fishes. But many fish do not form oral teeth. Vestigial expression or divergent function?
Result: pax9 is required for formation of upper jaw bones and barbels in zebrafish, but dispensable for non-oral teeth.
Support ancestral function in building peri-oral structures from condensed mesenchyme rather than a specific requirement for teeth

Immunofluorescence of mouse, anole, and chicken lungs showing epithelium in green and smooth muscle actin in magenta

New preprint from my postdoc work! Using fluorescent imaging, scRNA-seq, and ATAC-seq of mouse, anole, and chicken embryos, we provide evidence that birds have co-opted vascular smooth muscle to generate the pulmonary smooth muscle in their lungs. More on this later!

Last major paper of my #MSCA is finally out!! I modeled and mapped over 300 fish species in three orders in 3D to demonstrate how incorporating a depth perspective may offer a view of open-ocean biodiversity patterns that differs from a typical 2D approach.
