Ex situ conservation provides less mobility to the organisms due to relatively smaller habitat or area than the in situ. Principles of in situ and ex situ conservation of biodiversity In situ conservation is the on-site conservation of genetic resources in natural populations of plants or animal species such as forest genetic resources, in natural populations of tree and animal species. It means the conservation of biodiversity in their natural habitats itself. Established botanical and zoological gardens, conservation stands; banks of germplasm, pollen, seed, seedling, tissue culture, gene, and DNA, etc. For e.g. Hence, we can say that both In situ and Ex-situ are the method of conservation. Gap Analysis, a conservation evaluation technique, is an essential step in this process (Margules and Pressey 2000; Langhammer et al. 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 Teagan species. In this type of conservation the threatened animals and plants are taken out from their natural habitat and placed in a special area or location where they can be protected and given special care. Because our natural systems face many threats, conserving them is […] In situ is Latin for “on site”, in situ conservation is therefore the conservation of species diversity within normal and natural habitats and ecosystems. Therefore, the protection and efficient management of wild species and their environment is the prime objective of conservation. Article History ABSTRACT Received 30 October, 2016 Received in revised form 09 December, 2016 Accepted … The basic difference between in situ and ex-situ lies in the habitat place where the process is carried out. 4. 4. It provides less mobility to the organism because of the small habitat area. Ex-situ conservation measures can be complementary to in-situ methods as they provide an “insurance policy” against extinction. Zoological parks, botanical gardens and wildlife safari parks serve this purpose. 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. For e.g. In situ conservation. Integration of In-Situ and Ex-Situ Conservation Programs. For in situ, you're really looking to main ecological integrity. There is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. Example- Zoo, aquarium, seed banks, botanical gardens, etc. Ex situ conservation. Establish a protected area network, with appropriate management practices, corridors to link fragments restore degraded habitats within and outside. Ex situ conservation literally means, "off-site conservation". In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. I can't seem to find many specific examples where in situ or ex situ has been used to conserve a species. Ex-Situ Conservation: Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. In-situ conservation provides the required green cover and its associated benefits to our environment. Ce terme est utilisé dans de nombreux domaines pour décrire divers processus, notamment biologiques. Examples of In situ Conservation National Parks, Wild Life sanctuaries, Biosphere Reserves, Gene Sanctuaries Examples of Ex situ Conservation 2. In situ conservation may be viewed as a dynamic process that allows the continuance of the evolutionary processes that result in genetic diversity and adaptation. We have discussed both the conservation methods in detail and the major differences between the two. By comparison, ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. The main objective of ex situ techniques is to support conservation by ensuring the survival of threatened species … This method maintains the genetic diversity extant in the population in a manner that makes samples of the preserved material readily available.

Ex situ conservation means the conservation 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. There two important objectives of conservation which are given below: 1. By comparison, ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. In-situ conservation of Biodiversity includes biosphere reserves, national parks, wildlife sanctuaries, etc. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Ex-situ techniques include: seed storage, captive … What are the Similarities Between In Situ and Ex Situ La conservation de la biodiversité et des ressources génétiques est un phénomène important. In situ and ex situ conservation: Complementary approaches for maintaining biodiversity Haileab Zegeye Department of Biology, Faculty of Natural and Computational Sciences, Debre Tabor University, P. O. Especially now that humans have destroyed the natural habitat of most species, ex situ conservation may be the only prudent way forward. Methods. Key Areas Covered. 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… we save the entire forest to save the tiger. Outside, off site, or away from the natural location. Zoos and aquariums, as conservation organizations, have long been involved in partnerships to work toward biodiversity conservation (Field and Dickie, 2007). Having copies at the national level adds an extra layer of protection against the loss of these important genetic resources in case of gaps in management, change in preferences and use by the local community and so on. But it is free of threats like predators and poaching. Biodiversity possesses rich and diverse fauna and flora and unique natural beauty in its different ecosystems. In this type of conservation the threatened animals and plants are taken out from their natural habitat and placed in a special area or location where they can be protected and given special care.

By continuing to use our website, you agree to our. In-situ methods use conservation areas as "warehouses" of biological information. What is In Situ – Definition, Examples, Importance 2. Conservation Methods 4.1 Ex Situ versus In Situ Methods. Ex-situ conservation, also known as off-site conservation is the conservation mode in which species conservation takes place outside of their natural habitats. Preserving the quality and purity of the environment. Also Read: Biosphere Reserves in India |Biodiversity Hotspots of the World. This approach is called in in-situ (on site) conservation. The overall goal of conservation is to mitigate the loss of biodiversity and preserve ecosystem services, species, and genetic diversity for the future. In situ Conservation is one of the methods of the conservation of genetic resources in natural populations of plant or animal species. La conservation ex situ signifie littéralement la conservation « hors site ». Advantages of ex situ conservation Protection from predation and poaching. or in the form of gene pools and gamete storage, germplasm banks for seeds, pollen etc. Quel est In situ - Définition, exemples, importance 2. Ex-situ (‘off site’) conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat. 5. In situ et ex situ Deux méthodes sont utilisées pour décrire différents processus biologiques tels que la biorestauration et la conservation des organismes. It is one of two basic conservation strategies, alongside in-situ conservation. conservation, ex situ conservation, ecosystem conservation, species conservation, static conservation, dynamic conservation and others. Captive Breeding, Zoo, Gene Banks, Sperm and Ova Banks, Animal Translocation, Seed Banks, Aquarium, In vitro fertilization, Cryopreservation, Tissue Culture, Safaris. Continue A. Ex-situ Conservation. Biodiversity conservation is accomplished in a number of ways. This is the first step to linking ex situ conservation to in situ conservation using community seedbanks as a medium. And even with only few founding individuals, successful breeding and restitution can take place. The Large Copper Butterfly is a good example of this. Contrast in situ. Start studying Biology- conservation in situ and ex situ. Conservation of biodiversity is done in two ways In-situ and Ex-situ conservation. So, the correct answer is 'Seed bank'. Also Read: National Parks and Sanctuaries. In situ conservation. Si la conservation a été faite dans les populations naturelles d'espèces végétales ou animales, on parle alors de conservation . It is the process of protecting an endangered species, variety or breed, of plant or animal outside its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, an artificial environment which is similar to the natural habitat of the respective animal and within the care of humans, example are zoological parks and wildlife safaris. Units of ex situ conservation include zoological parks, botanical gardens, and seed banks. In order to ensure the maintenance of biodiversity, there is a need to employ complementary in situ and ex situ conservation. Ex-situ conservation Ex situ or ‘off-site’ conservation means the conservation of components of biological diversity outside their natural habitats. Botanical Gardens (Ex-situ) for example, BOTANIC GARDEN OF THE INDIAN REPUBLIC (BGIR), NOIDA has been set up to facilitate ex situ conservation and propagation of rare and threatened indigenous plants of the country; Problem: area and funds : They do not get as much media attention, public support and charity like the zoos. Ex Situ conservation means conservation outside the habitats by perpetuating sample population in genetic resource centres, for example, zoos, botanical gardens etc. In other words, it is a set of conservation techniques involving the designation, management, and monitoring of biodiversity in the same area where it is encountered. Also known as off‐site. The essence of the in situ conservation techniques is hidden in their stress on the onsite protection of biodiversity. Ex situ conservation is the preservation and propagation of species and populations, their germ cell lines, or somatic cell lines outside the natural habitat where they occur. Essentially areas that have a far greater biodiversity value and ecological value, but are not necessarily natural in and of themselves. Start studying Biology- conservation in situ and ex situ. Establishing a balanced cycle of harvest and renewal so that a continuous supply of natural resources is ensured. So, essentially, in-situ means at the same place; and ex-situ means outside the place. When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected.E.g. Hence, Seed Bank is an example of Ex Situ conservation. Figure 02: Ex-Situ Conservation . Zones clés couvertes. Ex situ conservation means the conservation of components of biological diversity outside their natural habitats. 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 Teagan species. In situ is Latin for “on site”, in situ conservation is therefore the conservation of species diversity within normal and natural habitats and ecosystems. Ex-Situ Conservation: Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Bio-geographic regions and Bio-geographic provinces of India, Difference between In situ and Ex-situ Conservation. Biodiversity Conservation.
