Plant cryopreservation consist of the storage of seeds, pollen, tissue, or embryos in liquid nitrogen. 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. [6]
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 [a] is a Latin phrase meaning 'in place' or 'on site', derived from in ('in') and situ (ablative of situs, lit. ' place '). [3] The term refers to the examination or occurrence of a process within its original context, without relocation.
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. However, cryo-conservation can be an expensive strategy and requires long term hygienic and economic commitment for germplasms to remain viable.
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 ...
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.
In-situ conservation involves protecting or restoring the habitat. Ex-situ conservation, on the other hand, involves protection outside of an organism's natural habitat, such as on reservations or in gene banks, in circumstances where viable populations may not be present in the natural habitat. [84]
There are eleven possible conservation roles [14] [13] that are given to each species that is evaluated by the assessment. These roles are as follows: Ark, Rescue, In situ Conservation, In situ research, Husbandry research, Applied Ex situ Research, Mass Production in Captivity, Conservation Education, Supplementation, Biobanking, and doing ...
