Abstract

| We compared the behavior of two subspecies of Podarcis hispanica lizards in cages that had been chemically marked by a saurophagous snake, the viper Vipera latastei. One of the subspecies (P. h. atrata) has experienced a relaxation from predation pressure by this viper, as snakes were eradicated from the island it inhabits over 100 years ago. Nevertheless, individuals from P.h. atrata responded to the snake's chemicals similarly to individuals from a population of P.h. hispanica, currently sympatric with V. latastei. Lizards exhibited more stress-indicating behaviors (foot shakes, tail vibrations, sudden starts), became less mobile, and tongue-flicked more while moving in a snake-inhabited terrarium than when in a clean, unfamiliar terrarium. |
