A hibernation factor is a protein used by cells to induce a dormant state by slowing or halting the cellular metabolism. [1] This can occur during periods of stress, [1] randomly in order to allocate "designated survivors" in a population, [1] or when bacteria cease growth (enter stationary phase). [2]
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.
During the hibernation season, this animal shows strongly reduced metabolism each day during the rest phase while it reverts to endothermic metabolism during its active phase, leading to normal euthermic body temperatures (around 38 °C).
A new study analyzes the blood cells of bats (of both the hibernating and non-hibernating varieties) and humans to understand the role these cells play in keeping mammals alive during prolonged ...
Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is known as hibernation if it occurs during winter or aestivation if it occurs during the summer. Daily torpor, on the other hand, is not seasonally dependent and can be an important part of energy ...
Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in ...
Hibernation is voluntary, whereas torpor is involuntary, like breathing. There are many animals that do go into full hibernation. True hibernators include squirrels , mice, bats, and turtles .
Circannual cycles can be defined by three primary characteristics: persistence in the absence of apparent time cues, the capacity for phase shifting, and stability against temperature fluctuations. [3] Classified as an infradian rhythm, it occurs less frequently than a circadian rhythm. This cycle was first discovered by Ebo Gwinner and ...
