What are the disadvantages associated with torpor?

Disadvantages of torpor for animals There is an indication that torpor reduces immunological abilities, postpones maintenance and repair processes, increases vulnerability to predation (Radzicki et al., 1999) and could impair memory formation and/or memory maintenance (Millesi et al. 2001).

What happens during torpor?

It's called torpor. Torpor occurs when an animal lowers its heart and respiratory rate down to a point that saves energy, but is not the near death of hibernation. Humans lower their heart and respiratory rate every night when they go to sleep, but torpor slows the rate down even further.

What factors triggers torpor?

It expends energy, but this energy loss is offset by how much energy is saved in the torpid state. This state is triggered by ambient temperature and the availability of food. Bears, raccoons, and skunks are all "light hibernators" that use torpor to survive the winter.

What is the difference between torpor and hibernation?

Torpor involves physiological changes related especially to body temperature, metabolism, and water balance. Hibernation is when an organism spends the winter in a state of dormancy; it is long-term multiday torpor for survival of cold conditions.

What is torpor give two examples?

Mammals, birds, and some marsupials undergo torpor. More specific examples include the California pocket mouse, the kangaroo mouse, the white-footed mouse, many species of hummingbirds, big brown bats, Richardson's ground squirrel, and fat-tailed Dunnarts (a marsupial).

Why is torpor important?

Torpor enables animals to survive periods of reduced food availability. ... 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.

Do humans undergo torpor?

Even though humans don't typically go into torpor of their own volition—and our bodies typically prevent it by shivering—Drew explains that there's no single “hibernation molecule” or organ that humans lack. In fact, torpor can be induced by doctors in extreme circumstances.

What is hypothermic torpor?

A second diagnostic feature of torpor, then, is that animals are capable of rewarming actively at any time during a bout of torpor (37), whereas hypothermic animals are unable to do so without an external source of heat.

Does torpor only occur in Endotherms?

Although torpor during development in endotherms is likely to occur in many species, it has been documented in only a few. ... This suggests that in placentals torpor is a derived trait that evolved secondarily after a homeothermic phase in certain taxa perhaps as a response to energetic challenges.

What is the state of torpor?

torpor, a state of lowered body temperature and metabolic activity assumed by many animals in response to adverse environmental conditions, especially cold and heat.

What is torpor in hamsters?

Torpor means temporary hibernation and hamsters can go into it when the environment that they're in drops below a certain temperature. ... So if a hamster feels extremely cold then they'll go into torpor and it's completely normal for them to do that.

Why do bears torpor?

Like hibernation, torpor is a survival tactic used by animals to survive the winter months, and is triggered by colder temperatures and decreased food availability. Torpor also involves decreased breathing and heart rates, and lower metabolic rate. A bear's body temperature reduces slightly.

How long does torpor last in hamsters?

In addition to deep, multiday torpor bouts alternating with short arousal episodes during the hibernation period, common hamsters can also enter shallow torpor bouts (STBs), lasting for < 24 h at a minimum body temperature between 30 and 20°C.

What do torpor means?

Definition of torpor

1a : a state of mental and motor inactivity with partial or total insensibility. b : a state of lowered physiological activity typically characterized by reduced metabolism, heart rate, respiration, and body temperature that occurs in varying degrees especially in hibernating and estivating animals.

What does Torpidity mean?

1a : sluggish in functioning or acting a torpid mind. b : having lost motion or the power of exertion or feeling : numb. c : exhibiting or characterized by torpor : dormant a torpid bird.

How do animals conserve energy through torpor?

The common poorwill conserves energy when food is limited by entering a state of torpor for extended periods of time. ... Because all major life functions (breathing, moving, pumping blood, maintaining body temperature, etc) require energy, reducing body temperature or slowing heart rate is one way to conserve energy.
