Evolution of Beauty

Another interesting science article in the New York Times yesterday, exploring the evolution of beauty in animals. Want to know why those anoles running around The Bahamas have colorful throat “dewlaps”? This is the article to read.

Thoughts on recent animal introductions to Abaco

A recent issue of the journal, International Reptile Conservation Federation (IRCF), contains two short articles featuring recent observations of two new species introductions to Abaco. Below, I relay these findings and offer a few thoughts on what these recent observations suggest for the future of Abaco’s fauna. […]

More Anole Research

We spent some time on Abaco recently with Harvard post-doc Graham Reynolds.  He sent us this quick update on his research program – thanks Graham! (Some coverage of Graham’s research in the New York Times and The Scientist magazine)

Anolis sagrei, the Brown or Festive Anole, is rapidly becoming a model system for the study of ecology and evolution, […]

Racer eats Curly

Ali Ball sent me this cool photo of a Bahamian racer (Cubophis vudii) in the later stages of ingesting a Curly-tailed lizard (Leiocephalus cairinatus) in Little Harbour. She noted that it took so long for the snake to finish it’s meal that her husband had enough time to run up to the house and retrieve a camera in order to […]

Lizards have it tough!

Last week Craig sent me a few photos of a Curly-tailed lizard in the jaws of a Bahamian racer (Cubophis vudii).  While we often imagine Curly-tails as predators, they are certainly not at the top of the food chain here. Bahamian racers, boas, and red-tailed hawks (see previous post) undoubtedly consume many Curly-tailed lizards.

I don’t really know too much […]

Ever-adaptable anoles might cope with a hotter world

The Washington Post covers a recent article on how Anolis lizards may be able to adapt to climate change (LINK).

Male brown anoles move further from their place of birth


Jonathan Losos over at Anole Annals breaks down a new paper by the Calsbeek lab at Dartmouth. The topic of the paper is the dispersal of young away from their place of birth and the fitness consequence of that movement in brown anoles (LINK to pdf).
