Ex situ management can occur within or outside a species' natural geographic range. Individuals maintained ex situ exist outside an ecological niche . This means that they are not under the same selection pressures as wild populations, and they may undergo artificial selection if maintained ex situ for multiple generations.
Non-invasive monitoring of the dhole is crucial for knowledge about its conservation status. Monitoring of wildlife populations is an important part of conservation because it allows managers to gather information about the status of threatened species and to measure the effectiveness of management strategies.
The first historically documented discussions regarding the Calauit Safari Park took place when Ferdinand Marcos approached David Anthony "Tony" Parkinson, [3] an Englishman whose business venture at the time was the translocation of African animals into zoos, on the sidelines of the Fourth session of the United Nations Conference on Trade and Development (UNCTAD IV) held in May 1976 in ...
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 ...
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the ...
There are a variety of approaches to species reintroduction. The optimal strategy will depend on the biology of the organism. [4] The first matter to address when beginning a species reintroduction is whether to source individuals in situ, from wild populations, or ex situ, from captivity in a zoo or botanic garden, for example.
To help combat the decline, the International Black Rhino Foundation was founded in 1989. The IBRF worked with both in-situ conservation (protecting animals in their native habitat) and ex-situ conservation (protecting animals "off-site" such as in zoos or non-native nature reserves). [2]
Wildlife and livestock conservation involves the protection of wildlife habitats. Sufficiently large reserves must be maintained to enable the target species to exist in large numbers. The population size must be sufficient to enable the necessary genetic diversity to survive, so that it has a good chance of continuing to adapt and evolve over ...
