Recently my work on urban lizard locomotor performance was published in Proceedings of the Royal Society B. This manuscript is part of a special issue on urban evolution, “The Evolution of City Life”, which will be coming out in paper form any day now. Looking for the videos? JUMP straight to them at the bottom … Continue reading

A Good Start
Yesterday was the beginning of a 14 day research trip to Puerto Rico. So far the trip has been very exciting. I’m here with graduate student Elizabeth Carlen (@E_Carlen) and budding young biologist Jessica Li. We are working primarily at the University of Puerto Rico in Arecibo this time. Instead of staying at our … Continue reading
Dewlapping Anolis stratulus
On my trip to Puerto Rico this past fall I was able to get some decent video of Anolis stratulus dewlapping. Check it out! This work is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License.
Field Trip Recap: Bimini, The Bahamas
A couple of weeks ago I traveled to Bimini, in the Bahamas along with Harvard post-doc Graham Reynolds, Harvard graduate student Pavitra Muralidhar, and UMass Boston undergraduate, Jason Fredette. We went with the simple goals of kicking off a research project in the Losos lab on Anolis sagrei and to observe as many other herps as we could. … Continue reading
It’s getting cool in New England… time to head to Puerto Rico!
In May / June of this past summer I continued with my mark-recapture study by marking two new populations of Anolis cristatellus in Arecibo. It’s been 4 months since then, which means time to recapture again! This time I’m back for a full 6 weeks, with fairly ambitious plans. The main goals of this trip … Continue reading
Brown Anolis cuvieri
The crown-giant anole of Puerto Rico, Anolis cuvieri, is typically a strikingly bright emerald green lizard. A. cuvieri juveniles have a brownish coloration, which they lose as they mature. Except for some A. cuvieri that keep this brown coloration into adulthood. This color morph was documented in a 1975 paper by Rand and Andrews (“Adult Color Dimorphism and … Continue reading
Anecdotes of X-rays
One of the perks of using a digital xray system for morphological measurements is that I get to see all sorts of interesting things that are difficult to detect or are not visible to the naked eye. I picked out a few of my favorite xrays from my recent field trip to Puerto Rico. These … Continue reading
The trip in which everything that could go wrong did
We’ve had a fairly rough 2.5 weeks down here in Puerto Rico so far. Just about any minor issue that could go wrong has gone wrong. The daily inundating rain storms, far too frequent supply runs to Arecibo (2 hour drive, each way), delayed delivery of the Alphatag injection kit (for marking animals permanently), delayed … Continue reading
Forest anoles and Urban anoles
We have successfully made it through 4 days of habitat sampling and are only a little short of our goals on the timeline because of a massive rain storm that rolled through Mayaguez around 5pm yesterday. So far we have completed the habitat availability sampling at both sites and have collected habitat use data in … Continue reading
Puerto Rico!
I’m back in Puerto Rico for another field season! This trip we will be sampling pretty heavily in a forest and urban site in Mayaguez. We got in late sunday night and then yesterday we were hit with a pretty intense thunderstorm that caused flash flooding across the island, so we didn’t really get to … Continue reading
