This method can be used for virtually indefinite storage of material without deterioration over a much greater time-period relative to all other methods of ex situ conservation. Cryopreservation is also used for the conservation of livestock genetics through cryoconservation of animal genetic resources .
Remediation technologies are many and varied but can generally be categorized into ex-situ and in-situ methods. Ex-situ methods involve excavation of affected soils and subsequent treatment at the surface as well as extraction of contaminated groundwater and treatment at the surface. In-situ methods seek to treat the contamination without ...
Ex situ conservation is defined as the “conservation of components of biological diversity outside their natural habitats.” [50] Ex situ conservation is the conservation of genetic resources (species, varieties, cultivars, sub-species, landraces etc.) for food and agriculture outside their natural habitat, in a managed environment including ...
Captive breeding, or ex-situ conservation, has been used in a number of instances to save species from extinction. The principle is to create a viable population of a species in either zoos or breeding facilities, for later reintroduction back into the wild. As such a captive population can either serve as an insurance against the species going ...
Bioremediation techniques can be classified as (i) in situ techniques, which treat polluted sites directly, vs (ii) ex situ techniques which are applied to excavated materials. [8] In both these approaches, additional nutrients, vitamins, minerals, and pH buffers are added to enhance the growth and metabolism of the microorganisms.
Some endangered species in the country were reintroduced via ex situ conservation. Ex situ conservation is rearing or cultivating, including reintroducing, a plant or animal outside their natural habitat. The reintroduction of the Indian rhinoceros at the Dudhwa National Park was a form of ex situ conservation; it
A range of methods and models currently exist that can be used to determine how much habitat is to be conserved in order to sustain a viable population, including Resource Selection Function and Step Selection models. Modelling tools often rely on the spatial scale of the area as an indicator of conservation value.
Indirect methods include track stations, fecal counts, food removal, open or closed burrow-opening counts, burrow counts, runaway counts, knockdown cards, snow tracks, or responses to audio calls. [52] For large, terrestrial vertebrates, a popular method is to use camera traps for population estimation along with mark-recapture techniques.
