ResumoNormothermic hibernators respond proportionally to both peripheral and brain temperature changes like other mammals. Their quantitative responsiveness to peripheral and brain temperature inputs are consistent with body-size relationships seen in other vertebrates. The basic temperature regulatory mechanisms seen in seasonal hibernators are not altered with season although certain response parameters, such as vasomotion, are not obvious in prehibernating marmots. During hibernation, hibernators respond to peripheral- and core-temperature manipulation in a manner which is consistent with the contention that temperature is regulated in a similar but less precise manner to that seen during normothermia.
