Abstract
The effect of variable and constant temperature regimes on skin shedding frequency was studied in Tokay geckos of Northern and Southern Asian origin. At temperatures of 32.degree. C and above, shedding cycle duration shows a minimum of approximately 17-19 days, but at lower temperatures cycle length increases steadily. No evidence of circannual rhythms in shedding behavior was found. Shedding frequency is a function of general metabolic status in tokays.
