Ex situ

Ex situ ( Latin for "outside the [original] place") is the antonym (opposite word ) to in situ and is used as a technical term in various disciplines.

• In nature conservation , ex situ measures to preserve biodiversity are those that take place outside the actual habitat of a species, for example in botanical and zoological gardens or in gene banks . In-situ measures take place in the natural habitat, for example the designation of protected areas.

• In physics , an ex-situ measurement means that a time-dependent process cannot be recorded as an overall process (i.e. in situ ), but rather individual instantaneous measurements can only be made outside the process, from which the process must then be reconstructed.
