Scientists excited about new lizard species found in DR
Scientists from Canada and the United States are excited about the discovery of a new species of Greater Antillean anole lizard in the Dominican Republic, strengthening a theory that communities of lizards can evolve almost identically on separate islands.
The chameleon-like lizard has been dubbed Anolis landestoyi after naturalist Miguel Landestoy who first spotted and photographed it. Biologists are saying that it is one of the first new anole species found in the Dominican Republic in several decades.
Greater Antillean anoles are a perfect example of a phenomenon known as replicated adaptive radiation, where related species evolving on different islands diversify into similar sets of species that occupy the same ecological niches.
Most noticeable among these unique lizards are Cuban anoles from the Chamaeleolis group.
Chamaeleolis anoles look less like typical anoles and more like chameleons: large, cryptic, slow moving and prone to clinging to lichen-covered branches high in forest canopies.
Scientists believed there was nothing like these Cuban lizards on the other Greater Antillean islands until they discovered the new species in the Dominican Republic.
The Anolis landestoyi bears a strong resemblance to Cuba's Chamaeleolis anoles.
Nevertheless, it is thought to be at risk because it's restricted to a unique habitat only found in a small area in the western Dominican Republic that is rapidly disappearing due to illegal deforestation.
As reported in Eureka Alert, Miguel Landestoy, a self-taught Dominican naturalist and photographer who makes his living leading photographic and nature field trips and conducting conservation research throughout the Dominican Republic, first spotted the lizard on a trip to a forest near Haiti. He kept returning to the forest thinking this was an unknown lizard. When Landestoy saw it again several years later, he sent a better photo to American herpetologist Luke Mahler, an assistant professor at the University of Toronto who then traveled to the DR to confirm the sighting of the unknown lizard.
