The Strix occidentalis, or the California spotted owl, has a preferred temperature range of around 18.20-35.20 °C and is less tolerant to heat than most other birds, exhibiting behaviors such as wing drooping and increased breathing at 30-34 °C. Because of this they tend to live in environments that are resistant to temperature change such as ...
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. [2]
Ectotherms use external sources of temperature to regulate their body temperatures. They are colloquially referred to as cold-blooded despite the fact that body temperatures often stay within the same temperature ranges as warm-blooded animals. Ectotherms are the opposite of endotherms when it comes to regulating internal temperatures.
In dogs, the thermoneutral zone ranges from 20–30 °C (68–86 °F). [9] Domestic cats have a considerably higher thermoneutral zone, ranging between 30 and 38 °C. [10] In horses, the lower critical temperature is 5 °C while the upper critical temperature depends on the definition used. [11]
Allen's rule - Hare and its ears on the Earth [1]. Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, [2] [3] broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates.
The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
A thermophile is an organism—a type of extremophile—that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F). [ 1 ] [ 2 ] Many thermophiles are archaea , though some of them are bacteria and fungi .
Because many homeothermic animals use enzymes that are specialized for a narrow range of body temperatures, hypothermia rapidly leads to torpor and then death. Additionally, homeothermy obtained from endothermy is a high energy strategy [ 5 ] and many environments will offer lower carrying capacity to these organisms.
