Over 56,000 hours of locomotor activity of Taricha granulosa
were recorded using two types of low cylindrical plastic monitoring
chambers. This species shows distinct rhythms of activity under
normal day-night cycles, shortened day-night cycles, constant
darkness (DD) and constant light (LL). The rough-skinned newt is
day active and crepuscular. I...
