Abstract

The ability of hatchling pine snakes (Pituophis melanoleucus) to follow or avoid the chemical trails of conspecifics and a king snake (Lampropeltis getulus) on paper substrates was investigated inY-maze experiments. Hatchlings entered the arm with the adult conspecific trail and avoided the arm containing the king snake trail at a frequency much greater than that due to chance. The data support the hypotheses that pine snakes follow the chemical trails of adult conspecifics and avoid the chemical trails of a predator.

摘要

在 Y 型迷宫实验中，研究了幼蛇（Pituophis melanoleucus）在纸基质上跟随或避免同种成蛇和王蛇（Lampropeltis getulus）化学痕迹的能力。幼蛇进入带有同种成蛇痕迹的臂，而避免进入含有王蛇痕迹的臂的频率远高于随机频率。这些数据支持了以下假设：松蛇会跟随同种成蛇的化学痕迹，并且会避免捕食者的化学痕迹。
