As PhD student Dan Nicholson (above) can attest, the bad weather we sometimes encounter during our fieldwork can make one lose their mind. 

Our 2019 field team in Panama. We got a lot done!

We found a sloth!

Our 2018 field team in Panama. We attempted to do the classic Prom-staircase photo...judge for yourself whether that was a good decision or not...

The students often entertain themselves by modifying terrible photos they take of me in the field. This is one of the more mild versions...

Three of our experimental islands in the Panama Canal. We have released hundreds of uniquely marked lizards across these islands (and several others). The islands differ in their thermal and structural environments, exposing lizards to rapid environmental change. Each generation, we track genetic and phenotypic change in a whole suite of physiological, morphological, and behavioral traits. This system, as well as our work in The Bahamas, is providing insight into the evolutionary mechanisms involved in adaptation to rapid environmental change.

One of our experimental islands in The Bahamas, where we have transplanted nearly 700 lizards across islands that vary in their thermal conditions and habitat structure. We are testing hypotheses about adaptation to climate change and speciation in response to divergent selection.

Our custom made field temperature chamber that we use to measure lizard thermal performance.

In 2012, we transplanted a population of brown anoles to this warm, thermally variable site and measured their survival. We found that those individuals which ran fastest at the warmest temperatures and across the broadest range of temperatures were most likely to survive.

In 2013, in The Bahamas, we studied how lizards were adapting to offshore islands that differ in their thermal environments. This photo was taken on Coakely Island, an exceptionally hot cay that sits about 20 km off of the main island of Great Exuma. Lizards on this island are adapted to these very warm conditions. In the foreground sits our boat captain and guide, "Bonefish Stevie."

Teaching high school students how to collect data in the field on the island of Dominica. High school students are active participants in our research there. In fact, they collect 90% of our field data!

As its name suggests, the Dominican anole is endemic to the small island of Dominica in the Lesser Antilles. This is an incredible lizard---it has been able to adapt to nearly all of the island's environments, from cool, wet cloud forests to the hot, open areas along the coast. We are studying the physiology and behavior of this species to understand how it has been able to adapt to so many habitats. We are also studying its interactions with an invasive species, the Puerto Rican crested anole.

High elevation cloud forest on the island of Dominica. The Dominican anole can be found at high densities in these forests, despite daytime temperatures never getting much above 20 C.
