Insects that do not migrate from regions with the onset of colder temperatures must devise strategies to either tolerate or avoid lethal freezing of intracellular and extracellular body fluids. Insects that survive subfreezing temperatures are generally classified as freeze-avoidant or freeze-tolerant.
The bright colors of Grand Prismatic Spring and Yellowstone National Park, are produced by thermophiles, a type of extremophile.. An extremophile (from Latin extremus ' extreme ' and Ancient Greek φιλία (philía) ' love ') is an organism that is able to live (or in some cases thrive) in extreme environments, i.e., environments with conditions approaching or stretching the limits of what ...
Microscopic algae that can tolerate extremely cold temperatures can survive in snow, ice, and very cold seawater. On snow, cold-tolerant algae can bloom on the snow surface covering land, glaciers, or sea ice when there is sufficient light. These snow algae darken the surface of the snow and can contribute to snow melt. [18]
It must experience a period of cool temperatures, around 15–22 °C (59–72 °F), before development proceeds when the temperature increases to 24 °C (75 °F). The temperature during this time strongly influences the sex of the hatchling; in one study, 100% of eggs kept at 25 °C (77 °F) produced male turtles, whereas at 30 °C (86 °F), 89 ...
Japanese macaques can survive in cold temperatures of below −15°C (5°F), and are among very few primates that can do so.. Chionophiles are any organisms (animals, plants, fungi, etc.) that can thrive in cold winter conditions (the word is derived from the Greek word chion meaning "snow", and -phile meaning "lover").
Cold temperatures slow the blood, which can cause more severe cold weather injuries like frostbite. Without blood to warm the tissue, it freezes, and those ice crystals damage the cells and tissue ...
The body temperatures of many small birds (e.g. hummingbirds) and small mammals (e.g. tenrecs) fall dramatically during daily inactivity, such as nightly in diurnal animals or during the day in nocturnal animals, thus reducing the energy cost of maintaining body temperature. Less drastic intermittent reduction in body temperature also occurs in ...
An ectotherm (from Ancient 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.
