CORAL GABLES — Fairchild Tropical Botanic Garden may look serene at first glance, but beneath the resplendent orchids and majestic banyans, two invasive lizards are waging a turf war. The war started a few years ago when Cuban brown anoles, who have called South Florida home for about 100 years, came face to face for the first time with a new rival: crested anoles from Puerto Rico. As the two species, which look almost identical and occupy the same ecological niche, faced off, biologists were able to document who was winning, and more importantly, how quickly the losers were adapting to survive on new turf. A new study reveals that the losing species is adapting at a rapid pace, changing their behavior, but also their bodies.
