Ex situ conservation

(重定向自Ex situ)
A tank of liquid nitrogen, used to supply a cryogenic freezer (for storing laboratory samples at a temperature of about −150 °C).

Ex situ conservation literally means , "off-site conservation". It is the process of protecting an endangered species of plant or animal outside its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, which may be a wild area or within the care of humans. While ex situ conservation comprises some of the oldest and best known conservation methods, it also involves newer, sometimes controversial laboratory methods.
