Chronobiology of garter snakes : environmental and hormonal mechanisms mediating hibernation and reproduction

Creator:: Lutterschmidt, Deborah I.
Abstract:: Most vertebrates exhibit seasonality in many life history traits. Such seasonal rhythms are temporally organized via the transduction of environmental cues (e.g., photoperiod, temperature) into appropriate endocrine signals. However, among ectothermic vertebrates that undergo continuous winter dormancy, temperature is the only environmental cue available for synchronizing seasonal rhythms. Most intriguing...
