Summary
Two groups ofEurycea lucifuga were trained to move bidirectionally within separate training corridors by alternately supplying moisture to limestone-filled compartments located at each end. Both corridors were aligned horizontally along the magnetic North-South axis of the earth. One corridor was enclosed within a cube coil which rotated the magnetic field horizontally 90° clockwise, so that the group contained in this corridor moved perpendicular to the North-South axis of the magnetic field. The other corridor was in the normal earth's field so that this second group moved parallel to the horizontal North-South component of the magnetic field. Testing involved releasing both groups in the center of a cross-shaped testing assembly made up of the two training corridors. The two groups were confined together in a release device for 60 min before release. In several tests the two groups were significantly oriented (P<0.05) along the appropriate trained axes with respect to the normal or altered magnetic field. Movements in these tests did not reflect a consistent response to any other potential source of orientation cues (P<0.001). It is concluded that cave salamanders are able to (1) perceive the earth's magnetic field and (2) exhibit a directional response with respect to a magnetic field which indicates a learned relationship to the environment.
