ex situ conservation

Cryopreserved sperm are ideally suited to support in situ conservation activities. With continued shortage of animal protein, these sources also continue to be sources of interest. A. Ex-situ Conservation 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. In situ and ex situ conservation focuses on the maintenance of species diversity within or away from their natural habitats, respectively. In the developed nations, farm parks have increased in popularity and often contribute to meaningful maintenance of biodiversity through their association with responsible grassroots organizations. Indian J. Ex-situ Conservation Each Contracting Party shall, as far as possible and as appropriate, and predominantly for the purpose of complementing in-situ measures: (a) Adopt measures for the ex-situ conservation of components of biological diversity, preferably in … Resour. In-situ measures are the primary conservation approach because they provide a more holistic strategy for conservation, by allowing easier conservation of a greater number of ecological and evolutionary processes. Chicago/Turabian Style. the reintroduction of the Arabian oryx to Saudi Arabia 10. Complementary conservation strategies. Ex situ conservation methods for vegetatively propagated woody species traditionally relied on field or glasshouse collections. For ex-situ conservations the species to be conserved should be identified followed by adoption of different ex-situ methods such as, long-term captive breeding and propagation for the species which have lost their habitats permanently, short-term propagation and release of the animals in their natural habitat, animal translocation and reintroduction and advanced technology in the service of endangered species. Major genebanks conserving germplasms of proso, barnyard, kodo, and little millets worldwide*. Examples include tropical fruits such avocado, mango, mangosteen, rambutan, and cacao. Ex-situ ('off site', 'out of place') conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat to a place of safety, such as a zoological garden, botanical garden or seed bank. A model for biodiversity conservation is presented which includes: selection of target taxa for conservation, gene pool concepts, ecogeographic surveys, field surveying, clarification of conservation objectives, the two basic conservation strategies (in situ and ex situ) and the range of conservation techniques, and ways that conservation is often linked to some form of utilization. Ex-situ conservation, which is also known as off-site conservation, refers to the conservation of endangered species in the artificial or man-made habitats that imitate their natural habitats, e.g. Proc. It is the methods of conserving all the living species in the artful habitats that reflect their natural living habitats. It involves the transfer of genetic material away from the location where it is found. zoo, aquarium, botanical garden etc. Produce material for conservation biology research. 2, pp. 37–50, 2010. Units of ex situ conservation include zoological parks, botanical gardens, and seed banks. 2020; 9(4):446. Lively debate surrounds ex-situ techniques, with much deliberation over when ex-situ measures are appropriate and justified 4. Also, cryopreservation of embryos is difficult in pigs and not practiced for poultry. During the past 20 years, ex situ conservation has been marginalized by political developments including a campaign against alleged biopiracy, the Convention on Biological Diversity, and the International Treaty for Plant Genetic Resources for Food and Agriculture (Andersen, 2008; Wood and Lenné, 2011). Although nuclear genes can be adequately preserved using frozen sperm, cytoplasmic DNA found in animal mitochondria are contributed only via the ovum and can thus be preserved only by storage of cryopreserved ova or embryos.

It ensures easy accessibility of germplasm for evaluation and utilization. Ex-situ Conservation is one of the primary objectives of Botanical Survey of India (BSI). However, cryopreserved sperm cells are not particularly efficient for regeneration of a breed that has become extinct. For example, the global loss of amphibian species is mainly tackled through captive-breeding because the small body size, low maintenance requirements, repeated breeding and high fecundity of frogs allows a rapid build-up of captive populations 3. Embryo cryopreservation, however, is practical in cattle, sheep, and goat and permits conservation of the full genome, both nuclear and cytoplasmic. The Global Crop Diversity Trust (GCDT) supports the development of global crops (including some legumes) and regional strategies for ex-situ conservation and utilization of crop diversity. Eur. The risks associated with live-animal ex situ programs are therefore also high, especially in developing nations in which sustained funding for long-term conservation programs may not be available and risks of social and political upheaval are greatest. Technical guidelines and strategies in the use of ex-situ techniques have been developed by leading conservation bodies such as the International Union for the Conservation of Nature (IUCN 2002, Maunder and Byers 2005), the Botanic Gardens Conservation Initiative 16, the Center for Plant Conservation 17 and the World Zoo Conservation Strategy 18. There are more than 1500 botanic gardens and arboreta in the world containing more than 80,000 species. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. 3.1. All definitions are referenced, where possible preference has been given to internationally recognised definitions (for example those defined by international conventions or agreements). It is one of two basic conservation strategies, alongside in-situ conservation. Ex-situ conservation … Source: Coyne, C., Rebecca, M., 2013. The stresses on living organisms due to competition for food, water, space etc. These guidelines aim to: Ex-situ (‘off site’) conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat. Ex-situ conservation is defined at Differencesbetween.net as the “conservation of biological diversity outside their natural areas and is done through different methods like captive breeding, botanical garden, zoos, aquaria, and seed, sperm and egg banks. Lentil Germplasm Accessions Conserved Ex-Situ at NBPGR New Delhi. The major types of genebanks include the following: Seed banks: Seeds are the most convenient form for the conservation of PGR. The aim of the Ex situ Conservation Group is to promote and exchange information about orchid seed storage, micropropagation and the cultivation of orchids in living collections. The most recent inventory that includes 2655 accessions of cultivated lentil comprised of 2083 indigenous and 572 exotic accessions, which were introduced from different countries, have been conserved in the National Gene Bank of NBPGR (Table 3.2). In-Situ (natural home) 2.Ex-Situ (artificial home) Actual Question in CSAT 2011 (12.) The Global Ex-Situ Lentil Collection Held by the Global Gene Bank of ICARDA and Other National Gene Banks, David R. Notter, ... Irene Hoffmann, in Encyclopedia of Biodiversity (Second Edition), 2013. However it is known that pollen remains viable only for a relatively short time and is not suitable for long term conservation (Thormann et al., 2006), but may be useful for problematic species, especially for endangered plants when only one male plant remains. Especially now that humans have destroyed the natural habitat of most species, ex situ conservation may be the only prudent way forward. Additional guidance is provided by Article 9 of the CBD. 1. Conf. Sperm cells contain a sample of only half of the animal's DNA; therefore, restoration of an extinct breed from cryopreserved sperm requires a “grading-up” process in which sperm is used on females of a different breed over several generations to eventually create animals that have a majority of their nuclear genes from the cryopreserved breed. This was achieved most conveniently by employing reduced temperatures and was carried out initially with herbaceous crops. The creation of 'assurance colonies' and 'safety-net populations' for Endangered and Critically Endangered species has therefore led ex-situ measures to be likened to an insurance policy against extinction. can be avoided by ex-situ conservation there by providing conditions necessary for a secure life and breeding. Its primary objective is to support conservation by ensuring the survival of threatened species and the maintenance of associated genetic diversity. Arbora Publisher, Zvolen, pp 567–583, Zimmermann A, Wilkinson R, Hatchwell M, Dickie L, West C (2007) The conservation mission in the wild: zoos as conservation NGOs? Several companies offer cloning services on a commercial basis, but with a focus on unique, high-value individuals rather than populations. According to FAO (2013), there are 1750 genebanks globally conserving 7.4 million accessions of PGR (FAO, 2013). Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. (Eds. CONSERVATION OF BIODIVERSITY Protecting the loss of Biodiversity. This protects the species from predation and pressure from the environment. )Biosphere Reserve (b.) Such strategies are, for example, in use to tackle the global tortoise extinction crisis  11. Cultures can be readily switched to rapid multiplication regimes when required. Article 9 of the Convention on Biological Diversity (CBD) states that ex-situ measures should predominantly be implemented for the purpose of complementing in-situ measures, such as a system of protected areas. This is maintained by governments at different levels, educational institutions and with the international assistance as well. What is Ex-situ Conservation? Furthermore, the science-based approach to in situ conservation on-farm (Brown, 1999) has been ignored, superseded by an agenda which assumes implausible rates of beneficial in situ evolution (de Boef et al., 2013). Model for conservation in lentil germplasm. D. Blakesley, T. Marks, in Encyclopedia of Applied Plant Sciences, 2003. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. In ecology, the best method for the conservation of smaller populations is ex situ conservation. Chapman & Hall, London, UK. Ex situ conservation usually involves cryopreservation of gametes, embryos, tissues, or somatic cells or the storage of DNA, also known as “cryoconservation”, but may also involve live animals kept in farm parks, research farms, or other noncommercial settings. Vavilov All-Russian Scientific Research Institute of Plant Industry (VIR), Institute of Plant Production n.a. In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. This typically involves the designation of protected areas of land as either nature reserves or national parks Conserv Biol 23:773–6, Snyder NFR, Derrickson SR, Beissinger SR, Wiley JW, Smith TB, Toone WD, Miller B (1996) Limitations of Captive Breeding in Endangered Species Recovery. Ex-situ techniques are implemented in well-defined situations 9: Several high-profile case studies have demonstrated that ex-situ conservation measures can play a critical role in preventing species extinction, e.g. By comparison, ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. Ex situ conservation is a conservation method where the plant or animal species is conserved outside of their natural habitat. Ex situ conservation has several purposes: Produce material for reintroduction, translocation, reinforcement, habitat, and landscape restoration and management. This is a method of ex-situ conservation of threatened and endangered species in their respective regions. Table 3.3. For these reasons, cryopreserved sperm cells are the most common material used for ex situ conservation of endangered breeds. However, for many species, field genebanks remain the only available form of ex situ conservation. Many genebanks are now extracting DNA from the genebank accessions and conserving the material by cryopreservation (Dulloo et al., 2006). Ex-situ conservation is the most convenient, cost effective, and widely used method of conservation. Grow those species with recalcitrant seeds that cannot be maintained in a seed store. V.Y. There are more than 800 professionally managed zoos around the world with about 3000 species of mammals, birds, reptiles and amphibians. Ex situ conservation can take different forms, which are largely determined by biology and by the method of reproduction of the species to be conserved (seeded or vegetatively propagated), as well as the purpose of conservation and the intended use of the material (Dulloo et al., 2017a). Agropecuarias, Centro Regional de Investigación Carillanca, Plant Genetic Resource Department Aegean Agricultural Research Institute, General Commission for Scientific Agricultural Research, Plant Genetic Resources Institute, National Agricultural Research Center, Bangladesh Agricultural Research Institute, Biodiversity Conservation and Research Institute, Institute of Plant Production V.J. This technique is available only for a limited number of species, as specific protocols need to be developed for the cryopreservation of specific plants (Engelmann and Takagi, 2000; FAO, 2013). The African giant rat and the grass cutter are African rodents that have been sources of protein in West Africa from time immemorial. Island Press, Covelo,USA, WAZA (2005) Building a Future for Wildlife - The World Zoo and Aquarium Conservation Strategy. Manag. J Ecotourism 7:160–178, IUCN (2002) Technical Guidelines on the Management of Ex-situ populations for Conservation. The conservation of wild relatives of crop plants, animals or cultures of microorganisms provides breeders and genetic engineers with a ready source of genetic material. Zoological parks, botanical gardens and wildlife safari parks serve this purpose. Plants bearing these kinds of seeds normally are then conserved as live plants in the field. In-situ (“on site”) conservation refers to conservation techniques implemented in the same area where the conservation target (species, ecosystem, population) is encountered. Consequently, some 25 years ago, alternative in vitro approaches were considered. Peter Wyse Jackson, Lucy A. Sutherland, in Encyclopedia of Biodiversity (Second Edition), 2013. Wild Lentil Germplasm Accessions Conserved Ex Situ With the Global Collection Held by ICARDA and USDA-ARS. In the NATP projects, an effort for exploration and collection of lentil germplasm was intensified. T. I. Borokini, A. U. Okere, A. O. Giwa, B. O. Daramola, and W. T.

The conservation of components of biological diversity outside their natural habitats. Maxted N (2001) Ex Situ, In Situ Conservation. Conservation involves the protection and maintenance of natural resources – such as trees, water and wildlife Conservation can be either in situ (on site) or ex situ (off site); In situ conservation is the preservation of plant and animal species within their natural habitat.

Because our natural systems face many threats, conserving them is not easy, and must use many techniques. The main purposes of ex-situ collections are the rescue and preservation of threatened, Ex-situ conservation forms the basis of Article 9 of the. Figure 8.1. By continuing you agree to the use of cookies. The major collection of lentils was undertaken from the central and eastern parts of Uttar Pradesh, Uttarakhand, the northern districts of Himachal Pradesh, Haryana, Rajasthan, and parts of Bihar (Malik et al., 2001). 157–180. Cambridge University Press, Cambridge, UK, Maunder M, Byers O (2005) The IUCN Technical Guidelines on the Management of Ex Situ Populations for Conservation: reflecting major changes in the application of ex situ conservation. Biorepositories such as gene banks have an explicit ex-situ mandate. While in field gene banks, preservation of genetic resources is being done under normal growing conditions. Ex situ conservation has historically been a method of choice for PGR scientists and breeders, in view of the relatively easy access to the materials conserved in the ex situ facilities or genebanks. whole animals, pollen, seeds). Costs of ex situ live-animal conservation are high, however, involving feeding and daily care of breeding animals, and disease outbreaks or localized disasters may threaten endemic breeds (Carson et al., 2009). More detailed explanations are provided for a number of key terms, to provide further background information. clarify the role ex-situ measures should play in the global action plan of an endangered or critically-endangered species. In its simplified form, the concept is likened to Noah’s ark, wherein species are maintained in a place of safety until factors threatening their existence in the wild have been removed and reintroduction is likely to be successful 1. Recommendations for ex situ conservation programs thus generally focus on extensive use of frozen sperm cells. Which one of the following is not a site for in-situ method of conservation of flora? (a. Ex situ conservation is a technique of conservation of biological diversity outside its natural habitats, targeting all levels of biodiversity such as genetic, species, and ecosystems [1 1. However, not all kinds of seeds can be conserved in seed banks. 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. In: Levin SA (ed) Encycl. Conserv Biol 10:338–348, Jule KR, Leaver LA, Lea SEG (2008) The effects of captive experience on reintroduction survival in carnivores: A review and analysis. the reintroduction of the Arabian oryx to Saudi Arabia, clarify when ex-situ initiatives are warranted to complement in-situ conservation measures; and. Use of cloning in breed conservation thus relies on the assumption that continuing research will eventually result in substantial increase in efficiency of cloning new individuals from cryopreserved adult cells. Just like seeds, pollen is desiccated and conserved at low temperatures. Progress and Challenges in Ex Situ Conservation of Forage Germplasm: Grasses, Herbaceous Legumes and Fodder Trees. Genet. To do so, ex-situ institutions preserve the genetic or reproductive material of a target species, or take care of the living target species for the purpose of reintroduction. Ex situ conservation of genetic resources is a cornerstone of crop improvement for global food security by the CGIAR. Field genebanks are easy to set up, but they are space and time consuming, as they need to be regularly replanted. The periodic monitoring of the viability and timely regeneration of the materials is an essential part of ex-situ conservation, and vary according to the crop species and their reproductive systems (Breese, 1989). Table 3.2. Fig. Cryopreservation and subsequent in vitro fertilization of ova are not yet practical for domestic species. The base collections are regularly monitored for seed viability at an interval of 10 years. Twenty years ago, the need for an integrated system for conserving genetic resources for crop breeding was highlighted (Wood and Lenne, 1997). to safeguard populations or individuals that are in danger of physical destruction when protection in situ is not possible; to safeguard populations which are in danger of genetic deterioration; to ensure a readily available, continuous supply of reproductive material, either creating a production source or through storage; to allow commercial improvement of a species through breeding activities and supply of genetically improved reproductive material. Pollen banks: The conservation of pollen is also practiced by breeders for use in breeding work to bridge the gaps between male and female flowering time (Thormann et al., 2006). If ex situ conservation is to play an effective role in conserving wild plant diversity and supporting habitat conservation, appropriate levels of infrastructure and capacity need to be established (Maunder et al. ), Genetic and Genomic Resources of Grain Legume Improvement. Col. Ger. Such collections are expensive to maintain, are susceptible to environmental changes, and do not present a safe long-term option. Ex situ conservation is the conservation and maintenance of plant samples outside their natural habitat, either in the form of the whole plant, or as a seed, pollen, and tissue or cell culture. The European-based EURISCO system provides information about the ex-situ plant collections maintained in Europe (http://eurisco.ecpgr.org/). A significant advantage in plant conservation is that seeds can be collected for a vast majority of plants. Table 3.1. For conservation of an active collection, viability must remain above 65% for 10–20 years, whereas in a base collection, seed are stored at − 20°C to ensure long-term viability of seeds for > 50 years. In-situ conservation of Biodiversity includes biosphere reserves, national parks, wildlife sanctuaries, etc. The efficiency of use of sperm cells to restore a breed depends on the generation time and the fecundity of the species. This is a crucial conservation method for endangered species. Ex-situ (‘off site’) conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat. Further, ICARDA gene banks have global responsibility for the conservation of the lentil germplasm belonging to 70 countries, 1146 ICARDA breeding lines, and 583 accessions of 6 wild lentil taxa, representing 23 countries (Alabboud et al., 2009). Ex-situ Conservation. This well-functioning system was based on trust and a clear understanding of the benefits to food crop production in developing countries. In contrast, in cattle a minimum of 10 years would be required using conventional breeding techniques to produce even a small number of animals possessing 93.75% of the nuclear genes of the preserved breed. Although ex-situ and in-situ conservation were historically treated as distinct conservation strategies, both methods are implemented cooperatively within regional conservation plans in order to reach biodiversity conservation goals more effectively. Objectives of … That is, the conservation of selected plants and animals in selected areas outside their natural habitat is known as ex-situ conservation. Home Conservation Ex Situ.
