I just got back from a trip to the Bahamas with Losos lab post-docs Anthony Geneva and Alexis Harrison, accompanied by expert lizard catchers Inbar Maayan and Sofia Prado-Irwin (Harvard graduate student). We parted ways for the first few days of the quick trip, with Anthony and Sofia headed to Bimini and Alexis, Inbar, and myself on Abaco. Read more about the Bimini trip in Sofia’s recent post.
On Abaco, we stayed at the brand new Friends of the Environment Kenyon Center. We were really impressed by the great accommodations of this field station. The station was sustainably built and had all the modern amenities we could wish for. The field lab was large and equipped with microscopes and plenty of counter space. We were equally impressed by the staff and their outreach efforts. The Friends for the Environment does a fantastic job providing nature education to local kids from age 3 through college! Their ambitious organization seeks to provide high-quality and low-cost facilities for visiting scientists and to provide outreach and education to the local community. We spoke with the coordinators of the organization who told us that any time researchers are looking for extra hands in the field they are happy to arrange local students to assist. We strongly encourage others traveling to Abaco to stay here!

Our main goal on this trip was to capture Anolis sagrei to continue ongoing research into the amazing diversity among islands in this species. We were immediately struck by how much smaller the Anolis sagrei on Abaco were compared to those on the other islands we have been to. I was also struck by how many A. sagrei used the ground. I normally study Anolis cristatellus, and although they are the same ecomorph, I rarely see A. cristatellus on the ground. I also don’t recall seeing A. sagrei frequently on the ground on Bimini or Eleuthera. So observing these lizards, particularly the females, on the ground at such a high frequency (they literally scattered as I walked!) was very surprising. Is this common on other islands with A. sagrei and I just haven’t noticed before?
As with any good field trip, we also encountered a great diversity of herps. Although the only native anole to Abaco is A. sagrei (according to Powell and Henderson 2012), we also saw plenty of Anolis distichus and a few Anolis smaragdinus. We also saw the invasive Cuban tree frog (Osteopilus septentrionalis), the native Eleutherodactylus planirostris, and plenty of curly-tails (Leiocephalus carinatus). No live snakes to report, although we did come across a couple of roadkill Cubophis.
Although we found no Sphaerodactylus, we did find plenty of non-native Hemidactylus. Interestingly, Hemidactylus is not listed in Powell and Henderson’s (2012) list of West Indian amphibians and reptiles for Abaco. Can anyone ID this species (the photos are of two individuals) and tell me if this has been reported before for Abaco? Obviously Hemidactylus are widespread in the Caribbean, but I was surprised to see it absent from the species list for many of the Bahamas islands.
