Anolis lizards on the island of Jamaica do not show a reduction in signaling behavior during periods of visual "noise" created by the movement of windblown vegetation as Anolis on Puerto Rico do
The dewlaps of Jamaican Anolis are more brightly colored than those of the Puerto Rican lizards, and Jamaican Anolis expand and contract their dewlaps more rapidly than the Puerto Rican species do. What difference between the signaling systems of the Jamaican and Puerto Rican Anolis might allow the signals of the Jamaican species to be perceived even in visually noisy conditions?
