Bats hibernating in a silver mine. Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
v. t. e. The group that includes mammals and birds, both "warm-blooded" homeothermic animals (in red) is polyphyletic. Homeothermy, homothermy or homoiothermy[1] is thermoregulation that maintains a stable internal body temperature regardless of external influence. This internal body temperature is often, though not necessarily, higher than the ...
Chronobiologyis a field of biologythat examines timing processes, including periodic (cyclic) phenomena in living organisms, such as their adaptation to solar- and lunar-related rhythms.[1] These cycles are known as biological rhythms. Chronobiology comes from the ancient Greek χρόνος(chrónos, meaning "time"), and biology, which pertains ...
Senior dogs need more sleep as well since it helps "their bodies recover from daily activities." Other factors that can contribute to your dog's sleeping habits include environment, health issues ...
Heterothermy or heterothermia (from Greek ἕτερος heteros "other" and θέρμη thermē "heat") is a physiological term for animals that vary between self-regulating their body temperature, and allowing the surrounding environment to affect it. In other words, they exhibit characteristics of both poikilothermy and homeothermy.
Nocturnality is a behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is " nocturnal ", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. [ 1 ]
Cathemerality. Cathemerality, sometimes called "metaturnality", is an organismal activity pattern of irregular intervals during the day or night in which food is acquired, socializing with other organisms occurs, and any other activities necessary for livelihood are undertaken. [ 1 ] This activity differs from the generally monophasic pattern ...
Circannual cycle. Not to be confused with circadian rhythm. In chronobiology, the circannual cycle is characterized by biological processes and behaviors recurring on an approximate annual basis, spanning a period of about one year. This term is particularly relevant in the analysis of seasonal environmental changes and their influence on the ...
