Nettet20. jan. 2024 · Torpor and hibernation are powerful strategies enabling animals to survive periods of low resource availability. The state of torpor results from an active and drastic reduction of an individual’s metabolic rate (MR) associated with a relatively pronounced decrease in body temperature. To date, several forms of torpor have been described in … Nettet16. jun. 2024 · In the case of an animal like a mouse, torpor is entered when the creature hasn't been able to eat for a long period, usually around 24 hours or more. The mouse's body temperature, breathing, and heart rate all lower and its metabolism (a.k.a. fat burning—fat is an animal's 'battery') goes way down. Torpor can only last a few hours.
