### condition:

Hibernation
* Are active all winter.
* Most hibernation affects dormouses
  - lasts for months
* Most hibernation occurs in mammals
  - responses
* Some hibernation occurs in hollow trees
* attempts by domesticated hedgehogs can be serious or fatal.
* begins in the fall.
* common response to the cold winter of temperate climates.
* cuts down on the energy needed to stay alive.
* depends on temperature, species and abundance of food.
* differs from species to species.
* dormant sleep-like state.
* enables animals to survive long periods of cold.
* ends in the spring, and mating takes place soon afterwards.
* form of adaptation where the animal s metabolism slows down to very low levels
* great strategy that enables animals to conserve energy when food is scarce.
* happens when gopher tortoises metabolism runs low.
* helps animals survive the changing seasons.
* induces expression of moesin in intestinal epithelial cells.
* is akin to a period of deep sleep.
* is an adaptation that helps black bears survive the winter
  - inactive state that some animals go into during cold weather to survive
  - associated with a. b. c. d. circadian rhythms
* is by nearly full-grown caterpillars
  - the third-stage caterpillars
  - caused by cold, winter conditions
  - clearly a strategy to promote over-winter survival
  - controlled by an internal clock
  - dictated by climatic conditions and to a species trait
  - dormancy
  - like a very deep sleep
  - more than just sleep
  - much like the daily burrowing activities of the lizard
  - retirement
  - suggested by the seasonal accumulation of fat
  - the process that occurs in mammals such as birds during the winter
* is the way bears adapt to nature, and survive the harsh winter weather
  - conserve energy through the season when their food supply disappears
  - used by many organisms that remain hypothermic for days or weeks or months
  - usually a safe way to pass the cold winter
* is when an animal goes into a state of low metabolism due to extreme cold
  - animals slow down for the winter and fall into a sleep-like state
  - where the name dormouse comes from
* is, A state similar to sleep in which some animals pass the winter.
* key adaptation of the hedgehog during winter.
  - till the return of spring, when they wake back in a bony-skinny shape
* needs vary according to the type of turtle.
* occurs at the larval stage
  - during winter months
  - for about seven months
* occurs in egg stage
  - members of almost every type of mammal
  - on land and occasionally in streams and springs
  - when an animal remains inactive to save energy through the harsh winter
* often takes place in large groups.
* path of evolution that was taken by most animals to survive harsh winters.
* period of rest lasting several months.
* process of deep comatose sleep.
* provides a means for an animal to conserve resources when food is scarce.
* reduces the bear's energy consumption at a time when food is scarce.
* refers to the dormant state some animals go into to survive the winter.
* roosts in caves or mines.
* seems to be less complete in prairie dogs than in true ground squirrels.
* sleep-like state that lasts for extended time periods
* state of inactivity and metabolic depression in endotherms
  - reduced metabolic activity during the winter
* takes place in winter, and estivation takes place in summer
* technique that animals have developed in order to adapt to harsh climates.
* too behavioural adaptation for surviving harsh winters.
* turns off all power, thus conserving battery life.
* usually ends earlier in warmer, more southern regions
  - takes place in the fall when they retreat to any shelter they can find
* way for animals adapt to the changing climate
  - to avoid many of the stresses of winter
+ Dormouse, Characteristics, Hibernation
  * Hibernation is where the name dormouse comes from. The sleepy behaviour of the Dormouse character in Lewis Carroll's 'Alice's Adventures in Wonderland' also shows this trait.
