## Abstract The shortβterm effects of pinealectomy and melatonin treatment on ovarian activity in the lizard, __Anolis carolinensis__ were examined at various times of the year. Animals were maintained under short photoperiod (6L:18D) at a constant temperature of 31 Β± 1Β°C. Destruction of the epiph
Photo-sexual responses in Anolis carolinensis during the fall are highly temperature dependent and show distinct thermal thresholds. If body temperatures are maintained at 32Β°C (the species' preaerred temperature), day lengths of 13 hours or more stimulate testicular growth, whereas day lengths of 1
