Abstract
Pineal melatonin secretion mediates photoperiodic regulation of implantation of blastocysts in the female western spotted skunk. Autoradiography studies demonstrated that high affinity 2-[125I]iodomelatonin binding sites are present in the pars tuberalis but not in any other hypophyseal region or in the hypothalamus or thalamus of this pieces. This restricted localization of 2-[125I]iodemelatonin binding, which was characteristic of spotted skunks sacrificed at various times during their annual reproductive cycles, suggests that the pars tuberalis mediates photoperiodic responses in this species.
