Andean Herpetofauna This book provides a comprehensive and up-to-date account of the Andean herpetofauna, combining qualitative and quantitative information and insights.

Overall, lizards and snakes have repeatedly adapted to colder environments as they colonized high elevations. (3/3).

Our chapter: doi.org/10.1007/978-...

Full book: link.springer.com/book/10.1007...

We found that high-elevation species evolved faster in cold-tolerance traits, while heat-tolerance remained largely conserved. We also found repeated shifts between lowlands and mountains, with movements back to lowlands occurring even more often. (2/3)

I'm happy to share that, together with @juvelas.bsky.social and Daniel Vásquez-Restrepo to examine how Andean uplift influenced the evolution of South American squamates as part of the book Andean Herpetofauna: Explorations of Diversity, Ecology and Conservation by @springernature.com (1/3)

Climate and parasite pressure jointly shape traits mediating the coevolution between an ant social parasite and its host Abstract. Host–parasite relationships are often shaped by coevolutionary arms races. While abiotic influences on these dynamics are well documented, a comb

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!

Sea #otters have undergone distinctive evolutionary changes in the offspring size–number trade-off within the #Mustelidae. The changes involve larger and fewer offspring and more investment in offspring size than expected:

Parental age effects on offspring fitness in a wild population of a short-lived reptile Abstract. As organisms age, the fitness of the offspring they produce can decline, which is often attributed to parental senescence. However, few studies h

How to spot fake scientists and stop them from publishing papers Journals are considering doing identity checks to expose fake authors — but there are downsides.

A feature in Nature examines what journals are doing to confirm that the authors of a research paper are legitimate, and the downsides of more intense identity checks. #Academicsky 🧪

Loss of macroevolutionary species fitness explains the rise and fall of clades - Nature Ecology & Evolution The interplay between speciation and extinction rates shapes clade diversity dynamics. Using a novel phylogenetic model that includes living and fossil lineages, the authors estimate speciation and ex...

Excited to share our new paper where we find that the rise, decline and fall of clades is not explained by the usual suspects (diversity-dependence, ecological opportunities) but rather by species' insidious loss of macroevolutionary fitness: www.nature.com/articles/s41... 1/3

YouTube video by Linnean Society Mountains, Lizards, and the Battle with Temperature

A few weeks ago, I had the joy of speaking at the Linnean Society about my research on anole lizards 🦎 and how they handle the wild temperature changes of Neotropical mountains.

m.youtube.com/watch?v=FCV8...

After nearly 10 years studying the evolution of thermal physiology in Anolis lizards, I defended my PhD a few months ago! Now, I’m happy to start a new chapter: a postdoc in the Neurogenesis & Brain Tumors Lab, studying glioblastoma evolution; the most aggressive brain cancer.
