About Me

Welcome to my website! I am a PhD student at the George Washington University under the advisement of Dr. Sandy Kawano. I am a functional morphologist and evolutionary biologist broadly interested in how ecology shapes trait evolution. I am particularly interested in convergence in the face of similar ecological demands. While I am a fish biologist at heart, I have found myself studying a wide range of vertebrates. My past and on-going research has focused on unraveling trends in fish feeding morphology, fish with suction cups, and mainland anole ecomorphology. For my PhD, I am currently studying salamanders and major the water to land transition. Browse my website to learn more about my research and recent updates or feel free to email with any questions and inquiries.

New Paper Alert! Are the Caribbean anole ecomorphs present on the mainland?

Morphologically similar anoles from the mainland and Caribbean.

Caribbean anole lizards are popular among biologists for being a textbook example of convergent evolution. On four islands in the Caribbean, anoles have repeatedly evolved groups of species (ecomorphs) with similar ecologies and morphologies. These ecomorphs demonstrate the strong relationship between habitat and morphology in Caribbean anoles and have been extensively studied since they were first proposed in the late 1960s to early 1970s. However, the anole ecomorphs have really only been applied to Caribbean anoles and its unclear whether their relatives in Central and South America also fit the bill. That is until now...

We measured the body proportions of 200+ species of island and mainland anoles to investigate their morphological similarities. We took advantage of the relationship between habitat and morphology in Caribbean anoles and used it to assign mainland species into the Caribbean ecomorphs. We found that 1) many mainland species resemble the Caribbean ecomorphs both ecologically and morphologically, 2) ground-dwelling mainland anoles belong to new a ecomorph class that is uncommon in the Carribbean, and 3) island and mainland anoles are more morphologically similar than previously believed.

There is still a lot left to learn about mainland anoles. Despite our findings, many mainland anoles are morphologically distinct from the established ecomorphs or seemingly represent intermediate ecomorph species. This suggests there may be other ecomorphs waiting to be described or that there are other factors that complicate the evolution of mainland anoles. Because the ecology of mainland anoles is severely understudied compared to their Caribbean counterparts, increasing our knowledge in that arena will surely provide better insights.
