Ex situ conservation

It is one of two basic conservation strategies, alongside in-situ conservation. Seed banking[ edit ] The storage of seeds in a temperature and moisture controlled environment.

People find it easier to relate to and have Ex situ conservation with animals which are more similar to ourselves, particularly if they are cute and cuddly at least in appearance, if not in fact! These facilities provide not only housing and care for specimens of endangered species, but also have an educational value.

Instead, ex situ conservation removes the species from its natural ecological contexts, preserving it under semi-isolated conditions whereby natural evolution and adaptation processes are either temporarily halted or altered by introducing the specimen to an unnatural habitat.

Additionally many private collectors or other Ex situ conservation groups hold animals and they engage in conservation or reintroduction efforts.

Bulk up germplasm for storage in various forms of ex situ facility. Organisms are well attended to, provided food, security, medical aid and hence have a greater life -span and reproductive capacity.

It is important to manage captive populations in a way that minimizes these issues Ex situ conservation that the individuals to be introduced will resemble the original founders as closely as possible, which will increase the chances of successful reintroductions.

The Wollemi pine is another example of a plant that is being preserved via ex situ conservation, as they are being grown in nurseries to be sold to the general public.

It is to be used as a last resort, or as a supplement to in situ conservation because it cannot recreate the habitat as a whole: It is estimated that worldwide, over million people visit zoos every year. Selective breeding processes are put in place. Several high-profile case studies have demonstrated that ex-situ conservation measures can play a critical role in preventing species extinction, e.

Mating can therefore be arranged by computer, to ensure that genetic diversity is preserved and in-breeding minimised always assuming the animals involved are prepared to co-operate. In many cases the species was actually extinct in the wild at the time of reintroduction Arabian Oryx, Pere David Deer, American Bison.

Several species are now solely represented by animals in captivity. It is also important to avoid mating two individuals with very different mean kinship values because such pairings propagate both the rare alleles that are present in the individual with the low mean kinship value as well as the common alleles that are present in the individual with the high mean kinship value.

In the John Crow Mountains, 32 percent of the species of flowering plants are endemic. Some of these include: As a last resort, ex-situ conservation may be used on some or all of the population, when in situ conservation is too difficult, or impossible.

Some biased expenditure on their survival may therefore be justified. The introduction of new individuals will only lead to stress and tension as individuals fight for limited territory and resources such as food.

The mean kinship value is the average kinship value between a given individual and every other member of the population. For example, the Zoological Society of San Diego has established a " frozen zoo " to store such samples using cryopreservation techniques from more than species, including mammals, reptiles, and birds.

The in-situ concept is best understood in contrast to ex-situ conservation. Or where the taste and cooking characteristics of traditional varieties compensate for their lower yields.Situ is a Latin word, meaning site.

So, essentially, in-situ means at the same place; and ex-situ means outside the place. Wildlife conservation is broadly classified into these two types. ADVERTISEMENTS: Some of the major Differences between In-situ and ex-situ Conservation are as follows: In situ Conservation: 1.

It is conservation of endangered species in their natural habitats. ADVERTISEMENTS: 2. The endangered species are protected from predators.

3. The depleting resources are augmented. 4. The population recovers in natural environment. Ex Situ Conservation Methods Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats.

This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. Nov 25,  · Animated Video created using Animaker - wsimarketing4theweb.com More ex situ.

Ex Situ Conservation Ex situ conservation is the conservation and maintenance of samples of living organisms outside their natural habitat, in the form of whole plants, seed, pollen, vegetative propagules, tissue or cell cultures. Ex-situ (‘off site’) conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat.

It is one of two basic conservation strategies, alongside in.
