Anolis sagrei, or the brown anole, is a lizard endemic to the Antilles that produces headbob displays for territorial aggression and sexual attraction. It has been hypothesized that these displays are honest signals of body condition, so they are evolutionarily more likely to garner attention and a response from receivers. In this study, we looked at the effects of body temperature on the display by controlling the body temperature during territorial headbob displays. We examined whether the speed (or abruptness) of display motion patterns was altered by changes in body temperature. In another experiment we tested whether or not the lizards could sense a small difference in the speed of display movements.. Results indicated no significant difference in temperature effects or ability to sense those slower display movements. This could indicate that Anolis sagrei is less temperature-sensitive than initially thought, which could have important implications for conservation in terms of the threat of climate change. We also looked at the effects of rapid shifts in direction of motion observed in the visual displays. Our preliminary results suggest that these abrupt changes of direction seen in the lizard displays may make them highly visible, and likely to attract the attention of conspecifics.
