winter or cold season dormancy.
the state in which some animals spend the winter, with extremely low temperatures and metabolic rates. During this state, the brain shows no activity.
When an animal sleeps most of the winter only waking once or twice.
The inactive or dormant state of insects during winter.
a time of long sleep that some animals undergo during the harsh time of year
winter period of rest or dormancy
Period of time when an animal becomes inactive or dormant, usually during winter. Allows an animal to survive harsh conditions using less energy than when active.
A period of dormancy or inactivity, varying in length depending on the species, and occurring in dry or cold seasons. Metabolic processes are greatly slowed and body temperatures may drop close to the freezing point.
the act of retiring into inactivity; "he emerged from his hibernation to make his first appearance in several years"
sleep or rest period during winter
Hibernation is a state of inactivity in an animal and may be viewed as a survival strategy that can be very successful in environments in which food is scarce or just difficult to find during a long, cold winter season. Dropping into deep hibernation or into a torpid state allows the animal to use their body's energy reserves at a slower rate than they would if they were maintaining themselves at their typical basal metabolic rate. Some ecologists refer to hibernation as "time migration". Hibernation allows the animal to skip over the cold, stressful seasons and only expend itself fully in those months of abundant food and moderate climatic conditions. A major disadvantage to hibernation, though, is that the hibernating animal is quite defenseless when it is in a deep hibernative or even torpid state. A very secure hibernating den (the "hibernaculum") is needed to protect the inactive animal.
Overwintering in an inactive state.
the winter sleep of animals (Bears go into a deep sleep and may not wake at all. Groundhogs enter a period of dormancy, where their heart pumps only a few times a minute.)
the period of winter dormancy for certain organisms, characterized by a great decrease in metabolism
A prolonged dormancy or sleeplike state in which animal body processes such as heartbeat and breathing slow down drastically and the animal neither eats nor drinks. Nearly all cold-blooded animals and a few warm-blooded animals hibernate during the winter in cold climates. Extremely large aggregations of bats, crickets, and spiders hibernate in some caves.
passing the winter in a dormant or inactive state with lowered metabolism and heart rate.
The torpid or resting state in which some animals pass the winter; cessation from or slowing of activity during the winter; especially slowing of metabolism in some animals.
period of winter inactivity, during which normal physiological processes are greatly reduced, thus requiring less energy
A state of dormancy or reduced activity typically entered at the onset of winter. Hibernating saves the animal a great deal of energy at a time where food is not readily available. Also referred to as "overwintering."
A period of inactivity induced by cold. In the wild, many animals pass the winter via hibernation.
A sleeplike state that some animals go into during the winter to save energy.
Winter dormancy in animals characterized by a great decrease in metabolism.
(noun) - also referred to as overwintering, the act of entering a time of dormancy or inactivity that lasts through a specific period of time (such as a season), enabling an animal to survive through severe weather. Butterflies that hibernate in the winter may do so at any stage of development, depending on the species. Most often, however, hibernation occurs during the pupal stage. Also, hibernate (verb).
hibernus: winter] • The state of inactivity of some animals during winter; marked by a drop in body temperature and metabolic rate.
Passage of winter season in sleep or restful state.
Dormancy during winter, generally accompanied by lower metabolic rate and temperature.
State of being in which the animal lies in a near comatose state for the duration of the winter.
The suspension of activity during the winter, cold period.
to spend the winter in a dormant state
A sleep-like state which allows an animal to survive the winter
Torpor brought on by extended cold temperatures
reduction of biological activity by organisms during winter, or, more generally, during cold periods. True hibernators, such as hoary marmots and Arctic ground squirrels, reduce their body temperatures close to freezing and cannot be readily awoken.
Sleeplike state with a depressed metabolic rate. Sometimes used to describe a project with low levels of activity.
a dormant (inactive) state. In true hibernation, the body temperature, heart rate, and breathing rate decreases drastically and the animal typically lives off stored fat.
a time during which an animal is in a sleeplike dormant state, living off reserves of body fat, with slower metabolism and decreased body temperature and pulse rate
The condition of torpor in winter.
hibernator the state that some animals enter during winter in which normal physiological processes are significantly reduced, thus lowering the animal's energy requirements. The act or condition of passing winter in a torpid or resting state, typically involving the abandonment of homoiothermy in mammals. the state that some animals enter during winter in which bodily functions slow down, reducing their energy requirements so that they can live through a season with little food.
Hibernation is a state of inactivity and metabolic depression in animals, characterized by lower body temperature, slower breathing, and lower metabolic rate. Hibernation conserves energy, especially during winter. Hibernation may last several days or weeks depending on species, ambient temperature, and time of year.
