| Abstract |
|
The alligator snapping turtle, Macrochelys temminckii , is capable of detecting and responding to the presence of chemosensory cues from two naturally-occurring prey species, the Mississippi mud turtle, Kinosternon subrubrum, and the common musk turtle, Sternotherus odoratus. Preference tests were conducted in an experimental chamber in which juveniles of M. temminckii were exposed to dechlorinated water in one-half of the chamber and an odor plume from water that had been occupied by either S. odoratus or K. subrubrum. Juveniles of M. temminckii spent significantly more time in water containing prey odor cues and also exhibited more rapid movements and more frequent episodes of gular pumping, as compared to those exhibited by turtles in untreated water. The ability to utilize odor cues is discussed with respect to detection of prey and patch residence time.
