The response of the lizard, Anolis sagrei, to the introduction of a larger lizard predator, Leiocephalus carinatus, which naturally colonized a small island in the Bahamas between April 1996 and April 1997. The graphs show the average perch height (cm) and perch diameter (mm) of A. sagrei before colonization by L. carinatus (April 1996) and following colonization from April 1997 to April 1999.
