Color-changing Females: Just Blending in or Born to Stand Out?? Across the Anolis genus, color and color change are used in a variety of ways, from camouflage to signaling. While many studies have focused on male coloration, few have explored the more subtle fe…

A pair of Ehiopian grass frogs (Ptychadena nana) on the cover of PNAS this week!

Happy to share that our paper on the #evolution and #genomics of the most common #color polymorphism in #frogs is now out in @pnas.org! My favorite frogs even made the cover of this week’s issue! 🎉🐸🎉

Having Sir David Attenborough narrate a story based on our findings on the dyeing poison frog was something that I never imagined, even in my wildest dreams. Now it’s happening, in the new BBC series “Parenthood” (Episode on Freshwater)! 🤩 www.youtube.com/watch?v=1Zih...

Map of Bioko Island with photos of male (Phase J, green) and female (Phase F, orange) forest reed frogs (Hyperolius tuberculatus) and the crater lake habitats at which the study was conducted.

A project that started during my PhD: why is the Forest Reed Frog (and #reedfrogs in general) sexually #dichromatic. More questions than answers but it looks like sexual niche partitioning is not the explanation 🐸🏝️🎨 big thank you to my coauthors for their patience! academic.oup.com/iob/article/...

Conservation needs to focus better on maintaining & enhancing the processes that allow ecosystems to function & adapt in a rapidly changing world

New paper out on the dangers of using patterns across spatial climate gradients to predict what will happen with changing climate. That includes species distribution modeling. Space-for-time substitution can be misleading in sign, not just the magnitude of effects.

Our paper, led by Eva van der Heijden, shows the work of an international team combining phylogenomics, hybridisation tests, population and comparative genomics and pheromone analyses to resolve the taxonomy and evolution of two rapid radiations of glasswing butterflies. www.pnas.org/doi/10.1073/...

So very excited for the magnum opus of my #PhD to finally be out in @pnas.org. 🎉🎉 We demosntrate that mutualistic co-mimicking tropical butterflies not only converge in light microhabitat but, as a consequence, have also converged in visual system morphology! 1/n😀

What are people's thoughts on covering HW equilibrium in intro bio? Is it really necessary, or could it be left to upper-level genetics or evo classes?

It would’ve awesome if you consider having a virtual meeting (as Evolution does), for all those researchers working in mega diverse countries to be included in the conversation too.

There are some very good folks involved with Colossal and the biotech is cool. But I agree - the so-called de-extinction work is irrelevant to practical conservation and distracts from what should be MUCH bigger priorities. It’s totally Frankenstein. And the $10B valuation seems totally 🥜
