For my dissertation I am testing hypotheses regarding the function and quality of signals given by prey to an approaching predator, focusing particularly on the responses of Anolis lizards to a snake predator under natural conditions.  I am doing experiments to test the "flash concealment" and the "pursuit deterrent" hypotheses, the two likeliest hypotheses that explain the function of these signals.  The quality of the signal that is, whether the signal is an honest indicator of a lizard's escape ability is tested by correlating individual endurance capacity to the frequency of signal given against the predator.  If signals are honest indicators of the prey's ability to escape, a positive correlation between signal's intensity and performance capacity is predicted.  Finally, it has been suggested that differences among species in the use of conspicuous displays against predator is correlated with differences among species in physiological capacity.  The effect of physiological capacity is evaluated by comparing the responses three closely related species that share the same predator.
