Hello everyone,
As part of some ongoing work comparing muscle physiology and performance among Anolis species, I am in search of data on the Field Active Body Temperature (Tb) of Anolis chlorocyanus so that I am sure to perform data collection at relevant temperatures. Unfortunately I have been unable to locate Tb data for this species in the literature, so I hoped one of you might have this information and be willing to share it with me. Any help would be greatly appreciated!
I’ve just returned from a trip to Martinique collecting data for a project I’m working on. In the process of collecting data and animals to bring back for work in the lab, I was able to travel all over to see Anolis roquet across the island, and photograph the different ecotypes/subspecies and their habitats. I was extremely impressed with how variable the island and the Anolis were, and I thought I’d share some of those images with everyone here.
As a bit of background, Martinique is formed from five separate geological regions that each were represented historically as their own precursor islands that joined together to form the current island (Thorpe et al. 2008). As a result of this process, A. roquet on the island is represented by four modal haplotype lineages, with their distribution strongly correlating with the boundaries of those geological regions, except for one modal haplotype lineage being shared between two (Thorpe et al. 2003). Anolis roquet lives across the island in a wide range of habitat types. Their occurrence in disparate habitat types has yielded a number of ecotypes with highly variable coloration and patterning (Thorpe et al. 2012). This variation was significant enough that six subspecies of A. roquet were described by Lazell (1972), all of which are pictured below.
While in Martinique, we were staying in an area called Gros-Morne, which is in the north-central part of the island. This area is part of the central geologic region and the Anolis in this area are from the mesic/transitional ecotype, which is the most widespread form and is what has been considered to be the nominate subspecies, Anolis roquet roquet. This particular portion of the central geological region, however is toward the montane area, so here the animals are more toward that end of the spectrum than the xeric form. Here are a couple photos of animals from this area, as well as a couple shots of the garden and area they were collected:
