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 .
In-situ conservation is the on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. [1] This process protects the inhabitants and ensures the sustainability of the environment and ecosystem.
in situ, which consists in managing populations on-site, dynamically evolving in their natural environment. [6] [7] In situ methodologies include: conservation in natural populations (in nature) on farm conservation; ex situ, which consists in conserving individuals or populations out of their natural environments. Ex situ gene bank ...
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 ...
Ex situ methods, by contrast, examine phenomena or objects outside their original context. The natural sciences frequently implement in situ methodologies. Geological studies employ field analysis of soil composition and rock formations, while environmental science relies on direct ecosystem monitoring to obtain accurate environmental data.
In-situ conservation of seed-producing plant species is another conservation strategy. In-situ conservation involves the creation of National Parks, National Forests, and National Wildlife Refuges as a way of preserving the natural habitat of the targeted seed-producing organisms. In-situ conservation of agricultural resources is performed on-farm.
For live cells/tissues, germplasm resources can be stored ex situ in seed banks, botanic gardens, or through cryopreservation. Cryopreservation is the process of storing germplasm at very low temperatures, such as liquid nitrogen. [5] This process ensures that cells do not degrade and keeps the germplasm intact.
For such breeds, to ensure that their critical genetic diversity is not lost, conservation programs are required. Several approaches for conservation can be applied, including in situ conservation with live animal populations, and ex situ conservation or cryoconservation involving the freezing of genetic materials. In many instances, both of ...
