Pallas cat conservation. Acquiring germplasm 20 B. Natural disasters can easily wipe out important organisms in affected regions. In situ is Latin for “on site”, in situ conservation is therefore the conservation of species diversity within normal and natural habitats and ecosystems. Gene Sanctuaries provide a way to preserve both the wild species and natural ecosystems. what are advantages of in-situ-both species and habitat are conserved-larger populations can be protected -less disruptive than removing organisms from their habitats -chances of population surviving are greater than with ex-situ methods . Examples of ex situ conservation are zoos, gene banks, botanical gardens, and aquariums. It is one of two basic conservation strategies, alongside in-situ conservation. Animals in ex situ conservation live in very protected environments. Children learn about in situ and ex situ conservations in theory. Ex situ conservation is the technique of conservation of all levels of biological diversity outside their natural habitats through different techniques like zoo, captive breeding, aquarium, botanical garden, an… It involves the location, sampling, transfer and storage of samples of the target taxa away from their native habitat to be conserved at a remote site. Its primary objective is to support conservation by ensuring the survival of threatened species and the maintenance of associated genetic … It offers less mobility to the animals as it is smaller in area than the area of in-situ conservation. 2. Advantages of Ex Situ Conservation. Advantages Disadvantages Advantages Disadvantages in-situ conservation in-situ means conserving species where they are naturally found e.g. Ex-situ conservation involves the conservation of genetic resources of species away from their area of origin or development. 4. Advantages: 1. Conservation of plant genetic resources is achieved by protection of populations in nature (in situ) or by preservation of samples in gene banks (ex situ). They store seeds at extremely low temperature and humidity. The different advantages of ex-situ conservation are, • It gives longer life time and breeding activity to animals • Genetic techniques can be utilized in the process • Captivity breed species can again be reintroduced in the wild The project could be split in two activities: Help and support Zoo de Lyon to raise funds for work related to the Pallas cat Conservation in-situ and ex-situ. It is used to refer to the collection and freezing in liquid nitrogen of animal genetic resources in the form of living semen, ova or embryos. It offers less mobility to the animals as it is smaller in area than the area of in-situ conservation. The advantages of in-situ conservation can be summed up as follows: (1) In-situ conservation is a cheap and convenient way of conserving biological diversity as we play a supportive role only. Feasible for medium and long-term secure storage. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Animal shelters – Animal shelters are mostly designed to take in animals that have been abandoned. Advantages, risks, and opportunities.
