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]
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 ...
J.S. Alho and colleagues argued in 2011 that, although Allen's rule was originally formulated for endotherms, it can also be applied to ectotherms, which derive body temperature from the environment. In their view, ectotherms with lower surface area-to-volume ratios would heat up and cool down more slowly, and this resistance to temperature ...
If no source of nucleation is introduced, water can cool down to −48 °C without freezing. [10] Therefore, when an insect maintains its body fluids in a supercooled state, there is the risk that spontaneous ice nucleation will occur. The temperature at which an insect spontaneously freezes is referred to as the supercooling point (SCP).
Ways that animals can control their body temperature include generating heat through daily activity and cooling down through prolonged inactivity at night. Because this cannot be done by marine animals, they have adapted to have traits such as a small surface-area-to-volume ratio to minimize heat transfer with their environment and the creation ...
If you do this, you can opt to use or not use the fans, but the fans would help cool the house faster, Porter said. The outdoors can pull the hot air from your home, leaving a cooler temperature ...
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
Cooling down the body is a crucial part of any workout routine, as it helps the body transition from an active state back to a resting state. After intense physical activity, the heart rate is ...
