Acclimatization
From Wikipedia, the free encyclopedia
Jump to: ,
Acclimatization or acclimation is the process of an individual organism adjusting to a gradual While the capacity to acclimate to novel environments has been well documented in thousands of species, researchers still know very little about how and why organisms acclimate the way that they do.

Methods
Biochemical
In order to maintain performance across a range of environmental conditions, there are several strategies organisms use to acclimate. In response to changes in temperature, organisms can change the biochemistry of Organisms may also express specific
proteins called
heat shock proteins that may act as molecular chaperons and help the cell maintain function under periods of extreme stress. It has been shown, that organisms which are acclimated to high or low temperatures display relatively high resting levels of heat shock proteins so that when they are exposed to even more extreme temperatures the proteins are readily available. Expression of heat shock proteins and regulation of membrane fluidity are just two of many biochemical methods organisms use to acclimate to novel environments.
Morphological
Organisms are able to change several characteristics relating to their
morphology in order to maintain performance in novel environments. Examples may include changing of skin color or pattern to allow for efficient
thermoregulation, or a change in body size of offspring as a result of low food levels in the
ecosystem.
Theory
While the capacity for acclimation has been documented in thousands of species, researches still know very little about how and why organisms acclimate in the way that they do. Since researchers first began to study acclimation, the overwhelming ...
