Anoles in Paris

I’m spending the summer in Paris, and while the city of lights has much to offer, I assumed two months here meant two months away from my beloved anoles. As it turns out, this is not the case! Even though anoles are New World lizards, there are still Anolis moments to be had here. In the Jardin des Plantes, the zoo and natural history complex of Paris, I was excited to find an Anolis equestris in the herpetarium. I took a picture of the sign below the cage:

Also, on an admittedly un-anolis-related note, but one of herpetological relevance: in the chateaux of the Loire Valley, the most common animal featured in the coat of arms of old royal families (and therefore throughout the architecture of their palaces) is the salamander. Evidently, in the past, salamanders were believed to breathe fire and were widely popular as symbols of power. I’ve included only a couple of many examples of salamanders below:

Maybe the anole community could popularize our favorite genus in a similar way?

Wanted: Anolis brevirostris Juvenile Photo

Thom, Sanger, Michele Johnson, and I have been working on a paper on juvenile morphology and behavior in an anole community in Barahona, Dominican Republic. Our only problem is that A. brevirostris juveniles move so fast, we didn’t get any photos while we observed them.

So…does anyone have a photo of an A. brevirostris juvenile? If so, you will of course receive credit for your photo in addition to truckloads of good karma!

Looking Out for the Little Guy

Apologies for the messiness of the formatting; this is my first blog post, and it only got here with a lot of technical support from JLo! History is full of examples of the little guy getting left behind. Unfortunately, so is the study of anoles. Most anole studies focus on adult lizards, and while there is certainly much to be learned from adult-focused studies, to ignore juveniles is to cheat ourselves of a great opportunity to better understand Anolis life history.

As readers of this blog likely appreciate, anoles are a model system for understanding evolution. To gain a comprehensive understanding of the factors that led to their stunning diversity, it’s important that we understand how selection acted upon these lizards at all stages of life – not just adulthood. A lizard has to survive from hatchling to reach adulthood and until we know more about how juveniles interact with their environment we cannot determine whether selection has shaped the juvenile stages with the same intensity as it has adult traits.

Thom Sanger wrote an earlier post that discussed the growth of Anolis limb length: “Growing Limbs – But Not the Kind With Leaves.” According to his post, variation in adult limb morphology can be traced “all the way back to the point in development when the cartilaginous long bone anlagen are just forming.”

This past summer, I worked with Thom, Michele Johnson (Trinity University), and Trinity undergraduates Ellee Cook and Diego Castro to study the morphology and behavior of juveniles on grounds of the Coral Sol Resort in Barahona, Dominican Republic. My goal was to understand whether juvenile lizards behave similarly to adults and whether juveniles have the same body proportions as adults.
