dc.description.abstractThe purpose of this study was to assess the effects of early feeding experiences on subsequent responses to prey in the tegu, Tupinambis teguixin. Five-day old lizards were exposed to the odors of various prey and control substances on cotton-tipped applicators with the tongue-flick attack score (TFAS) chosen as the dependent variable. Each lizard was exposed to four stimuli: two controls (deionised water and cologne), and extracts from a mouse Mus musculus, and a lizard Ameiva ameiva, in a repeated measures, randomized block design, receiving one stimulus training session / day over a 40-day period. Tongue-flicks directed toward the applicator were counted over a 1 min period as well as the amount of time that elapsed from the first tongue flick to any bite that may have occurred. Live neonatal mice (but not A. ameiva), offered on a weekly basis, were used as a food source for tegus over a 10-month period. After 10 months, tegus were exposed to applicators containing control odors as well as those containing extracts from mice and lizards (A. ameiva). Mouse extracts elicited significantly higher TFAS as compared to those elicited by A. ameiva or control odors, suggesting that prey odors encountered in the environment shortly after hatching can influence prey preferences by these lizards later in life. These results also indicate that tegu lizards can learn to use specific odor cues associated with naturally occurring prey as releasers for subsequent hunting behaviors.en_US
