Father Sanchez has done it again! Here’s his commentary accompanying this lovely photo: “… today I was at the Guajataca State Forest. The lowland forms of Anolis gundlachi (one of my favorite anolines) are quite smaller – and frequently paler – than those of the highlands. Incipient speciation? One can only hope.”

As for the occurrence of the cool-loving A. gundlachi in lowlands, see the discussion of this stemming from the recent symposium on the effect of global warming on ectotherms.
