In 2003, Jоnаthаn Lоsоs аnd his research team experimentally introduced curly-tailed lizards (Leiocephalus carinatus) to islands populated by trunk-ground anoles that live primarily on the ground and have relatively long legs (Losos, J. B., T. W. Schoener, and D. A. Spiller. 2004. Predator-induced behaviour shifts and natural selection in field-experimental lizard populations. Nature 432: 505-508). The scientists wanted to know how the presence of the curly-tailed lizards, which are anole predators, would affect the habitat in which the anoles lived. In one experiment, Losos and colleagues measured the “perch height” (or how high off the ground a lizard was perched) for 24 individual anoles. They then placed either a curly-tailed lizard (experimental population) or an inanimate object of the same size (control population) in front of individual trunk-ground anoles and measured the perch height 10 minutes later. They then calculated the average change in the anole’s perch height in the experimental and control populations. The results of this experiment are summarized in Figure 1.
