The West Indian hummingbird, Eulampis jugularis, maintained its body temperature in torpor at 18� to 20�C over an ambient temperature range of 2.5� to 18�C. At ambient below 18�C oxygen consumption during torpor increased linearly with decreasing temperature. Thermal conductances were the same for resting and torpid Eulampis regulating their body temperatures at 40� and 18�C, respectively.

Seasonal changes in the critical arousal temperature of the marsupialSminthopsis crassicaudata correlate with the thermal transition in mitochondrial respiration
During periods of torporSminthopsis crassicaudata, a dasyurid marsupial, regulated its body temperature above about 16.3°C in summer and 13.0% in winter, and the lowest regulated body temperature was just above the temperature where changes were detected in mitochondrial respiration.
A new function for torpor: fat conservation in a wild migrant hummingbird
Monitoring of the daily energy state of hummingbirds in the field showed that migrant hummingbirds may use torpor when they are very fat and not presently energetically stressed, indicating a mechanism to conserve the energy stored for later use on migration.
Torpor in an Andean Hummingbird: Its Ecological Significance
Field studies on an Andean hummingbird showed that nocturnal torpor occurs more frequently and lasts longer in the winter, and a photoperiodically controlled rhythm that enables the birds to automatically conserve energy in early evening for possible metabolic expenditures required later in theWinter night.
Body temperature and metabolic rate during natural hypothermia in endotherms
This study shows that the degree of metabolic suppression during hypothermia can alternatively be explained by active downregulation of metabolic rate and thermoregulatory control of heat production.

There is strong evidence that hibernation is not only a voluntary but a well-regulated strategy to counter food shortage and increased energy demands during winter.
Regulated hypothermia in the desert shrew
The results suggest a compromise between the energy savings of a deep torpor and the unimpaired functioning of euthermia, which is apparently regulated by fine adjustments of metabolic heat production in hypothermic as well as euthermic desert shrews.
The Function of Torpor in Hummingbirds
Results indicated that torpor was used only in "energy emergency" situations at a minimum "threshold" of energy reserves and not to reduce nocturnal energy expenditures when net energy gains during the day were sufficient for overnight expenditures.
Regulation of Body Temperature
Birds are endotherms, a term indicating that they are able to increase their body temperature by generating a considerable amount of heat within their tissues instead of relying on heat gained directly from their surroundings.
The Impact of Daily Torpor on Energy Requirements in the Djungarian Hamster, Phodopus sungorus
Calculations show that daily torpor in Djungarian hamsters may serve to allow the continuation of foraging at low Ta's during winter in the Siberian steppe and save substantial amounts of energy by lowering average metabolic rates during the normothermic phase of the day.

Although P. californicus consistently enters into and arouses from torpor at ambient temperatures of 15° to 30°, the torpor cycle is severely disturbed at temperatures between 10° and 12°, and mice show irregular temporal patterns of torpor, do not enter torpor completely, and cannot arouse from torpora if body temperature falls below 15°.
