ex situ conservation

The African giant rat and the grass cutter are African rodents that have been sources of protein in West Africa from time immemorial. Biorepositories such as gene banks have an explicit ex-situ mandate. V.Y. This is a method of ex-situ conservation of threatened and endangered species in their respective regions.

Breeding populations in zoos, game farms, aquariums, botanical gardens, arboretums, seed banks 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. S.S. Ajayi, in Wildlife Conservation in Africa, 2019. In: Plant Genetic Conservation: The In-Situ Approach. The whole conservation status of wild species in ICARDA gene bank is given in Table 3.1. zoo, aquarium, botanical garden etc. The efficiency of use of sperm cells to restore a breed depends on the generation time and the fecundity of the species. In-Situ (natural home) 2.Ex-Situ (artificial home) Actual Question in CSAT 2011 (12.) Biodivers. DNA banks: PGR can also be stored in the form of DNA, the material that embodies the genetic information. Title: Ex Situ conservation 1 Ex Situ conservation 2 Ex situ conservation. Indian J. ICARDA has the global mandate for research on improvement of the lentils and its conservation. Field genebanks: Seeds that cannot be dried or do not tolerate low temperatures are termed recalcitrant (Berjak and Pammenter, 2004). 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. Such collections are expensive to maintain, are susceptible to environmental changes, and do not present a safe long-term option. The facilities where this conservation takes placed are termed field genebanks (Reed et al., 2004). In: Levin SA (ed) Encycl. 37–50, 2010. Lacy R (2010) Re-thinking ex situ vs. in situ Species Conservation. In the NATP projects, an effort for exploration and collection of lentil germplasm was intensified. whole animals, pollen, seeds). Its primary objective is to support conservation by ensuring the survival of threatened species and the maintenance of associated genetic diversity. Ex-situ techniques include: seed storage, captive … Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. In ecology, the best method for the conservation of smaller populations is ex situ conservation. ), TISSUE CULTURE AND PLANT BREEDING | Clonal Forestry, Ex situ conservation of wildlife: Domestication of the African giant rat (Cricetomys gambianus), Encyclopedia of Food Security and Sustainability, Australian Tropical Crops and Forages Genetic Resources Centre (ATCFC), Plant Genetic Resources Centre, BARI (PGRC, BARI), Institute for Plant Genetic Resources “K. Biol Conserv 141:355–363, Griffiths R, Pavajeau L (2008) Captive breeding, reintroduction, and the conservation of amphibians. Shoot tip culture methods were modified to slow down growth rates and hence reduce maintenance costs. (Eds. At this temperature, all the metabolic activities of the plant cell are suppressed, which guarantees the conservation of plant material in a genetically unaltered state. It offers less mobility to the animals as it is smaller in area than the area of in-situ conservation. Chicago/Turabian Style. Source: Coyne, C., Rebecca, M., 2013. clarify the role ex-situ measures should play in the global action plan of an endangered or critically-endangered species. This poses a high risk of genetic changes and may cause genetic erosion. DNA material is now becoming the most requested material from genebanks for molecular genetics and genomics studies (Andersson et al., 2006). Academic Press, San Diego, USA, pp 683–695. Table 8.1. The collected germplasm showed substantial variation in morpho-agronomic traits like plant growth habit, stem and foliage color, seedling color, high pod plant− 1, variation in seed coat color and grain size (Singh and Rana, 2006). Conf. 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. Zoological parks, botanical gardens, wildlife safari parks and seed banks serve this purpose. Maxted N (2001) Ex Situ, In Situ Conservation. Twenty years ago, the need for an integrated system for conserving genetic resources for crop breeding was highlighted (Wood and Lenne, 1997). Nikhil Malhotra, ... Rahul Chandora, in Lentils, 2019. Ex situ management is an important conservation tool that allows the preservation of biological diversity outside natural habitats while supporting survival in the wild. Also Read: National Parks and Sanctuaries. Techniques for collection, cryopreservation, and subsequent use of sperm cells are relatively well developed; a single collection provides a relatively large number of gametes, and multiple samples are relatively easy to obtain. It is one of two basic conservation strategies, alongside in-situ conservation. 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). 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. Ex-situ conservation involves maintenance and breeding of endangered plants and animals under partially or wholly controlled conditions in specific areas including zoo, gardens, nurseries, 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. Botanic Gardens Conservation International, Richmond, UK, Guerrant EOJ, Havens K, Maunder M (eds) (2004) Ex Situ Plant Conservation: Supporting Species Survival In The Wild. Objectives of … Ex situ conservation literally means “off-site.” It is the process of protecting an endangered species, variety or breed of plant and animal outside of its natural habitats and placing it in a new location within the care of humans. Ex-situ conservation Ex situ or ‘off-site’ conservation means the conservation of components of biological diversity outside their natural habitats. 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. FAO (2013) has developed international standards for the management of the different kinds of genebanks (seeds, field, in vitro and cryopreservation). In farm animals, sperm cells can be successfully frozen and stored for future use in all species, although success rates from use of frozen sperm vary considerably among species. This well-functioning system was based on trust and a clear understanding of the benefits to food crop production in developing countries. Global status of small millet germplasm maintained in different genebanks. Globally, about 1.1 million germplasm accessions of grain legumes are conserved in various gene banks. In-situ (“on site”) conservation refers to conservation techniques implemented in the same area where the conservation target (species, ecosystem, population) is encountered. However, access to modest numbers of cryopreserved embryos (in species for which this is possible) and/or small populations of breeding females preserved under either in situ or ex situ conditions is recommended to provide a source of cytoplasmic genes and allow efficient regeneration of the breed. Challenges in ex situ conservation include genetic issues that arise from limited numbers of individuals and founders, and husbandry and hybridization issues encountered during the growing out of collections. One major advantage of restricted growth techniques is that they utilize the same basic facilities as micropropagation. Vavilov All-Russian Scientific Research Institute of Plant Industry (VIR), Institute of Plant Production n.a. 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. Home Conservation Ex Situ. This type of in vitro conservation is done in liquid nitrogen at a temperature of −196°C. 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. Produce material for conservation biology research. the reintroduction of the Arabian oryx to Saudi Arabia 10. Ex-situ techniques target plant and animal populations. Ex-situ conservation Ex-situ conservation means literally, "off-site conservation".It is the process of protecting an endangered species of plant or animal by removing part of the population from a threatened habitat and placing it in a new location, which may … It ensures easy accessibility of germplasm for evaluation and utilization. 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. In the developed nations, farm parks have increased in popularity and often contribute to meaningful maintenance of biodiversity through their … Cryopreservation is the storage of material at ultralow temperature (−196°C) either by very rapid cooling, as used for storing seeds, or by gradual cooling and simultaneous dehydration, as being done in tissue culture. With continued shortage of animal protein, these sources also continue to be sources of interest. Zoological parks, botanical gardens and wildlife safari parks serve this purpose. 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). This is a crucial conservation method for endangered species. 157–180. 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. (2010). In vitro conservation: Plants can also be conserved in the form of tissues, embryos or cells in vitro. Lively debate surrounds ex-situ techniques, with much deliberation over when ex-situ measures are appropriate and justified 4. The European-based EURISCO system provides information about the ex-situ plant collections maintained in Europe (http://eurisco.ecpgr.org/). We use cookies to help provide and enhance our service and tailor content and ads. The base collections are regularly monitored for seed viability at an interval of 10 years. This protects the species from predation and pressure from the environment. Biodivers Conserv 4:595–607, Skroppa T (2005) Ex situ conservation methods. Chapman & Hall, London, UK. In these situations, selection for unique adaptational characteristics is relaxed, but with proper breeding management and adequate population size, key genetic characteristics of the breed can be retained for many generations. Genet., 76, 399–409. That is, the conservation of selected plants and animals in selected areas outside their natural habitat is known as ex-situ conservation. Ex-situ Conservation. 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. Ex situ conservation 1. 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. Many of the tropical islands are rich in the number of endemic faunal species it possesses, while its record in agro-biodiversity is very impressive as well. Use of cryopreserved gametes, embryos, and tissues is a more common form of ex situ conservation. Ex-situ conservation … Plants. Ex situ conservation means conservation which takes place off-site. In situ is Latin for “on site”, in situ conservation is therefore the conservation of species diversity within normal and natural habitats and ecosystems. The ex-situ conservation strategies include botanical gardens, zoological gardens, conservation stands and gene, pollen, seed, seedling, tissue culture and DNA banks. Many genebanks are now extracting DNA from the genebank accessions and conserving the material by cryopreservation (Dulloo et al., 2006). Ex-situ Conservation is one of the primary objectives of Botanical Survey of India (BSI). Moreover, they are very vulnerable as the germplasm is exposed to changing climatic conditions, pests and diseases, floods and droughts, etc. This was achieved most conveniently by employing reduced temperatures and was carried out initially with herbaceous crops. 3.1). 4: 446. For example, restoration of 93.75% of the nuclear genes (i.e., four generations of upgrading) can be accomplished in approximately 3.5 years in pigs, and use of 100 sows initially could conservatively result in production of 1000 breeding females by generation four. 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. This chapter gives some basic information on the ecology of the species, the techniques, and the technology of establishing a wild colony of rats, quarantine measures, and removal of ecto- and endoparasites. The mountain chicken is a Critically Endangered frog found only on Montserrat and Dominica and is the largest native amphibian in the Carribean. In-situ conservation of Biodiversity includes biosphere reserves, national parks, wildlife sanctuaries, etc. In: Singh, M., Upadhyaya, H.D., Bisht, I.S. Table 3.1. Island Press, Covelo,USA, WAZA (2005) Building a Future for Wildlife - The World Zoo and Aquarium Conservation Strategy. Such strategies are, for example, in use to tackle the global tortoise extinction crisis  11. Such seeds are termed “orthodox” seeds. In: Geburek T, Turok J (eds) Conserv. Table 3.3. Balmford A, Leader-Williams N, Green MJB (1995) Parks or arks: where to conserve threatened mammals? 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. 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. Live-animal, ex situ conservation can also occur at public-funded facilities, generally under conditions that at least approximate those found in commercial agriculture but which often do not replicate the particular conditions under which the breeds were evolved and traditionally used. 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. 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. The lentil germplasm accessions with ICARDA have been obtained from 113 global collection missions, and they include 1734 cultivated and 374 wild accessions. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Make available material for conservation education and display. In ex-situ conservation of seeds, seeds can be stored as active (medium term) and base (long term) collections. Generate skills and knowledge to support wider conservation aims. Both in situ and ex situ methods of biodiversity conservation are equally important. 2, pp. Seeds of lentils are generally orthodox in nature, and can be dried to a lower moisture content of ± 6% with minimum loss of viability. Captive breeding followed by re-introduction is a possible approach for endangered species conservation and preservation of geneti … The use of ex-situ conservation is recommended if in-situ conservation, the preferable conservation alternative, is not available or not functional for the near-term survival of a species. More detailed explanations are provided for a number of key terms, to provide further background information. Ex-situ conservation is the relocation of endangered or rare species from their natural habitats to protected areas equipped for their protection and preservation. The terms have been chosen to support understanding of biodiversity and conservation issues, and terms relating to biodiversity loss are complemented by those relating to conservation responses supported by international conservation organisations, governments, scientists and business sectors. 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. Ex-Situ Conservation 2. All definitions are referenced, where possible preference has been given to internationally recognised definitions (for example those defined by international conventions or agreements). 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. Growth retardants are also added to retard the plant growth. Seed gene banks make the easiest way to store germplasm of wild and cultivated plants at low temperature. Ex-situ conservation means the conservation of species outside their natural habitats. (a. Consequently, some 25 years ago, alternative in vitro approaches were considered. The conservation of components of biological diversity outside their natural habitats. However, cryopreserved sperm cells are not particularly efficient for regeneration of a breed that has become extinct. 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). Populations on both islands have been devastated by the amphibian chytrid fungus, first on Dominica from 2002 and subsequently from 2009 on Montserrat. 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. 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. By closely linking targeted, structured, science-based in situ conservation with ex situ genotyping and phenotyping, we would identify the most valuable resources to be conserved for the future. A significant advantage in plant conservation is that seeds can be collected for a vast majority of plants. There are more than 1500 botanic gardens and arboreta in the world containing more than 80,000 species. 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. 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? Home > A Level and IB > Biology > Advantages and Disadvantages of ex situ conservation Advantages and Disadvantages of ex situ conservation 3.5 / 5 based on 10 ratings 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). By comparison, ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. Institutes/genebanks with >100 accessions are enlisted. Just like seeds, pollen is desiccated and conserved at low temperatures. Likewise, in India, National Bureau of Plant Genetic Resources (NBPGR) is recognized as an independent institute for the preservation of genetic resources over the past four decades, which has prioritized the collection, conservation, distribution, and documentation of the genetic materials of important crops, including lentils. Ex situ conservation is a conservation method where the plant or animal species is conserved outside of their natural habitat. An unnecessary polarity has been created to justify funding to in situ conservation with no evidence of scientific value, and funds vital for science have been redirected to expensive distractions. Seeds are stored at sub-zero temperature for maintaining viability for decades. This is particularly useful for conserving vegetatively propagated crops, for example, potato. Cryopreservation and subsequent in vitro fertilization of ova are not yet practical for domestic species. Hanson, Jean; Ellis, Richard H. 2020. It involves the conservation of living organisms outside their ecological niche. Major genebanks conserving germplasms of proso, barnyard, kodo, and little millets worldwide*. 2020; 9(4):446. 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. Bulk up germplasm for storage in various forms of ex situ facility. It is one of two basic conservation strategies, alongside in-situ conservation. A glossary of definitions for terms relating to biodiversity, ecosystems services and conservation. Cultures can be readily switched to rapid multiplication regimes when required. 1. This article outlines why conservation is needed, the major threats to species, and how diversity is maintained at the ecosystem, species, and genetic levels. World Association of Zoos and Aquariums, Gland, Switzerland. Cryopreserved sperm are ideally suited to support in situ conservation activities. Restricted growth techniques have been used for a number of temperate woody species, including apple (Malus pumila) and pear (Pyrus communis). 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. The major collections of crop species were carried out in the region of the “Fertile Crescent” in Western Asia, where the lentil was domesticated. Wild Lentil Germplasm Accessions Conserved Ex Situ With the Global Collection Held by ICARDA and USDA-ARS. In this method of biological diversity conservation, sampling, shifting, storage and preservation of target taxa is carried out outside the natural habitat of the organisms. However, they do not alleviate some of the main problems associated with the culture of plant tissue in vitro, such as high costs of labor and space, and risks of somaclonal variation. Convention on Biological Diversity (CBD) 1992 1. Storage of sperm from a wide sample of males of a breed provides future access to the genetic material of these representative foundation animals. 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. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. It involves the transfer of genetic material away from the location where it is found. Model for conservation in lentil germplasm. The major collections of proso millet germplasm accessions are assembled in the Russian Federation, China, Ukraine, and India; barnyard millet in Japan and India; kodo millet in India and USA; and little millet in India. Grow those species with recalcitrant seeds that cannot be maintained in a seed store. Units of ex situ conservation include zoological parks, botanical gardens, and seed banks. Cryopreservation: For longer term conservation, plant explants can be cryopreserved directly in liquid nitrogen at −197 °C. can be avoided by ex-situ conservation there by providing conditions necessary for a secure life and breeding. M. Ehsan Dulloo, in Encyclopedia of Food Security and Sustainability, 2019. 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 is the most convenient, cost effective, and widely used method of conservation. Additional guidance is provided by Article 9 of the CBD. Conserv Biol J Soc Conserv Biol 22:852–61, Mésochina P, Bedin E, Ostrowski S (2003) Reintroducing antelopes into arid areas: lessons learnt from the oryx in Saudi Arabia. It also provides information on the feed requirements of the two rodents. 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). Lentil. What is Ex-situ Conservation? Cryopreserved embryos produced by mating 25 pairs of unrelated parents and bolstered by cryopreserved sperm from 25 unrelated males can effectively capture the genetic diversity of a breed for long-term conservation and future use.
