Our new paper on the evolution of hormone-phenotype couplings was just published in the journal Hormones and Behavior! We use quantitative evolutionary genetics and comparative transcriptomics to consider ways in which researchers can study the interface of hormones and phenotypes. Check out the paper to learn more.
 Kelly Wuthrich (who took the above photo), Leah Bakewell, and Noah Gripshover get soaked catching lizards in Panama! They are working on our NSF-funded research on how organisms cope with rapid environmental change.
Our new paper on how testosterone impacts gene expression in brown anoles was just published! In this article, we describe how testosterone-responsive genes in the liver eventually become sex-biased in expression as the sexes diverge in body size during development.

Our new broader impacts program called "Evolution in Action" has begun! Four student scientists are in Panama, studying evolution in the tropics. Check out the link to the program website for regular updates and more information!
 Our new paper on lens transmission in anurans and salamanders was just published in the journal Functiona Ecology! We found that ecological difference among species was important for explaining difference in spectral transmission in amphibians. Click the link to read the paper.
 Our new paper on the ecological dynamics of coral snake mimicry in the montane tropics has just been published! This work was the M.S. thesis of first author Lauren Wilson. We studied predator-based selection on coral snake mimicry in areas of edge sympatry and allopatry to coral snakes in the montane rainforest in Honduras. We found that counter to research in the lowland tropics, we did not consistently detect a protective function of mimetic coloration. Click the link to read the paper.
We have just published a new paper on the systematics of Mexican rattlensnakes! In this perspective piece, we consider recent revisions based upon mtDNA in the light of what is known about mitochondrial genome sequence evolution, and recommend restraint in the absence of robust data.

 Our new paper on the evolutionary origins of viviparity was just published in the Journal of Experimental Zoology B! In this perspective piece, collaborator Matt Watson and I note that many of the evolutionary origins of viviparity occur at high elevations, which are cold and have lower oxygen availability. We advocate for research to study the impact of hypoxia on development of embryos and juveniles under hypoxia in both live-bearing and egg-laying species. The lizard above is Yarrow's spiny lizard (Sceloporus jarrovii), which is viviparous lizard that is found at high elevations. Check out the link to read the paper!
 Our new paper on how habitat structure can impact vulnerability to climate change in slender anoles and brown anoles was just published in Biotropica! We found that habitat variability can permit behavioral compensation for a warming climate. Hence, the forest-dwelling slender anoles are more likely to be negatively impacted by a warming climate than brown anoles, which are found in habitats with greater thermal heterogeneity.
