    Department of Psychology, Monash University, Clayton, Victoria, Australia
    Physiol Behav 63:271-7. 1998
    ..These results suggest that ambient temperature is an effective zeitgeber for F. pennanti. As has been reported for other diurnal species, interindividual differences exist in the phase of entrainment to temperature cycles...
