I had a bit of free time to take photos along the Recodo Road this afternoon and managed to get a few nice shots of Anolis marcanoi and its spectacular dewlap. Anolis marcanoi was among the first anoles to be described with the aid of genetic data, with early electrophoretic work being used to confirm that it was genetically distinct from sympatrically distributed populations of A. cybotes that have white or pale yellow dewlaps (Webster 1975, Williams 1975 [they’re a bit of a pain to access, but both articles are available via the Biodiversity Heritage Library]). Although they were initially regarded as ‘sibling species,’ subsequent phylogenetic work suggests that A. marcanoi is in fact the outgroup to all remaining species of cybotoid anoles (A. cybotes, A. longitibialis, A. strahmi, A. breslini, A. whitemani, A. shrevei, and A. armouri). Interactions between A. marcanoi and A. cybotes were also the subject of Losos’s (1985) famous ‘lipstick’ study in which “True Red” lipstick was used to experimentally render the dewlaps of A. cybotes a similar hue to those of A. cybotes (A. marcanoi males, in turn, had their dewlaps painted white with “Superior Clown White Make Up” to make them look like A. cybotes). This study remains one of the only investigations to date to address the role of the dewlap in species-recognition. We have our last day of work in the field tomorrow before heading back to snowy Rochester!
