Ex-situ (‘off site’) conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat. Zoological parks, botanical gardens and wildlife safari parks serve this purpose. This protects the species from predation and pressure from the environment. 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. Furthermore, the science-based approach to in situ conservation on-farm (Brown, 1999) has been ignored, superseded by an agenda which assumes implausible rates of beneficial in situ evolution (de Boef et al., 2013). Ex-situ conservation … 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). Such strategies are, for example, in use to tackle the global tortoise extinction crisis  11. Lentil Germplasm Accessions Conserved Ex-Situ at NBPGR New Delhi. C R Biol 326:158–165, Gascon C, Collins JP, Moore RD, Church DR, McKay JE, Mendelson JR (2007) Amphibian Conservation Action Plan, Proceedings: IUCN/SSC Amphibian Conservation Summit 2005. Many of these botanic gardens now have seed banks, tissue culture facilities and other ex-situ technologies. 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. "Progress and Challenges in Ex Situ Conservation of Forage Germplasm: Grasses, Herbaceous Legumes and Fodder Trees" Plants 9, no. Table 3.2. 1. 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. 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. D. Blakesley, T. Marks, in Encyclopedia of Applied Plant Sciences, 2003. Ex-situ collections of plants are established by storing seeds, conserving pollen and through the storage of plant shoots in conditions of slow or suspended growth (in vitro conservation) 2. Ex-situ conservation means the conservation of species outside their natural habitats. 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 … 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. 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. For this reason, in vitro conservation can only be considered for short to medium-term conservation (Reed et al., 2004). For these reasons, cryopreserved sperm cells are the most common material used for ex situ conservation of endangered breeds. This well-functioning system was based on trust and a clear understanding of the benefits to food crop production in developing countries. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. 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). 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). Figure 8.1. Units of ex situ conservation include zoological parks, botanical gardens, and seed banks. Other institutions such as zoos and botanical gardens are increasingly taking on roles as genetic reservoirs against extinction and captive breeding for future re-introduction programmes. The method to conserve them consists of drying seeds down to a low moisture content of typically 3%–6% and storing them in refrigerators, freezers or cold rooms, depending on how long the seeds need to be conserved (Rao et al., 2006). 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. Genet. However, not all kinds of seeds can be conserved in seed banks. Also, cryopreservation of embryos is difficult in pigs and not practiced for poultry. Consequently, some 25 years ago, alternative in vitro approaches were considered. Resour. 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. 8.1). In situ and ex situ conservation focuses on the maintenance of species diversity within or away from their natural habitats, respectively. Bulk up germplasm for storage in various forms of ex situ facility. The conservation of components of biological diversity outside their natural habitats. 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. Botanic Gardens Conservation International, Richmond, UK, Guerrant EOJ, Havens K, Maunder M (eds) (2004) Ex Situ Plant Conservation: Supporting Species Survival In The Wild. 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. 157–180. ICARDA has the global mandate for research on improvement of the lentils and its conservation. 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. Plants bearing these kinds of seeds normally are then conserved as live plants in the field. (2010). Ex Situ. 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. Ex-situ techniques target plant and animal populations. Many of these zoos have well-developed captive breeding programmes. View at: Go… Model for conservation in lentil germplasm. 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. Vavilov Russian Scientific Research Institute of Plant Industry, Inst de Inv. J Ecotourism 7:160–178, IUCN (2002) Technical Guidelines on the Management of Ex-situ populations for Conservation. Furthermore, information can be retrieved on germplasm collections by Gene bank Information Management System (GIMS) at ICRISAT, GRIN-Global used at USDA-ARS (Cyr et al., 2009), PGR-Portal used at ICAR-NBPGR (http://pgrportal.nbpgr.ernet.in), and SINGER at CGIAR centers at the system-wide system. Recommendations for ex situ conservation programs thus generally focus on extensive use of frozen sperm cells. Fig. This is maintained by governments at different levels, educational institutions and with the international assistance as well. Approaches to ex-situ conservation of genetic resources include different methods like field gene banks, seed storage, and botanical gardens. Objectives of … Ex situ conservation means conservation which takes place off-site. Seeds are conserved for > 50 years without any loss of viability (Usberti and Gomes, 1998). 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. Globally, about 1.1 million germplasm accessions of grain legumes are conserved in various gene banks. Since its inception, systematic explorations have been conducted to augment lentil germplasm; area-specific and trait-specific collection trips were also undertaken. Its primary objective is to support conservation by ensuring the survival of threatened species and the maintenance of associated genetic diversity. This is particularly useful for conserving vegetatively propagated crops, for example, potato. Landmark research for pulses improvement. 3.1). 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. 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. 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. Examples include tropical fruits such avocado, mango, mangosteen, rambutan, and cacao. For. Because our natural systems face many threats, conserving them is not easy, and must use many techniques. 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. Source: http://www.fao.org/wiews-archive/germplasm_query.htm. 15–41. (Eds. Wild Lentil Germplasm Accessions Conserved Ex Situ With the Global Collection Held by ICARDA and USDA-ARS. Especially now that humans have destroyed the natural habitat of most species, ex situ conservation may be the only prudent way forward. Eur. through the production and assimilation of material for research, conservation education 12 and capacity-building 13. FAO (2013) has developed international standards for the management of the different kinds of genebanks (seeds, field, in vitro and cryopreservation). In-Situ (natural home) 2.Ex-Situ (artificial home) Actual Question in CSAT 2011 (12.) The efficiency of use of sperm cells to restore a breed depends on the generation time and the fecundity of the species. Table 3.1. 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. 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 is one of two basic conservation strategies, alongside in-situ conservation. Complementary conservation strategies. Which one of the following is not a site for in-situ method of conservation of flora? A significant advantage in plant conservation is that seeds can be collected for a vast majority of plants. Selection of Species and Source of Collection An extensive survey was conducted in Vindhyan region of U.P. S.S. Ajayi, in Wildlife Conservation in Africa, 2019. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Lacy R (2010) Re-thinking ex situ vs. in situ Species Conservation. Many genebanks are now extracting DNA from the genebank accessions and conserving the material by cryopreservation (Dulloo et al., 2006). Cryopreservation of somatic cells is also becoming common in ex situ conservation programs as an economically efficient approach to back up in situ populations and insure animal genetic resources against extinction. Seeds are stored at sub-zero temperature for maintaining viability for decades. 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. can be avoided by ex-situ conservation there by providing conditions necessary for a secure life and breeding. 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. Iyyappan Jaisankar, ... Chandrakasan Sivaperuman, in Biodiversity and Climate Change Adaptation in Tropical Islands, 2018. CONSERVATION OF BIODIVERSITY Protecting the loss of Biodiversity. It ensures easy accessibility of germplasm for evaluation and utilization. Such strategies include 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. 65th World Aassociation Zoos Aquariums Annu. In-situ (“on site”) conservation refers to conservation techniques implemented in the same area where the conservation target (species, ecosystem, population) is encountered. Maxted N (2001) Ex Situ, In Situ Conservation. Only seeds that can be dried to a very low moisture content and that can tolerate low temperatures (between −20 °C and +4 °C) can be stored in seed banks. It is the methods of conserving all the living species in the artful habitats that reflect their natural living habitats. Cryopreservation and subsequent in vitro fertilization of ova are not yet practical for domestic species. While in field gene banks, preservation of genetic resources is being done under normal growing conditions. 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. This is a method of ex-situ conservation of threatened and endangered species in their respective regions. Ex-situ conservation means the conservation of species outside their natural habitats. Ex-situ conservation is the most convenient, cost effective, and widely used method of conservation. 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. whole animals, pollen, seeds). Moreover, they are very vulnerable as the germplasm is exposed to changing climatic conditions, pests and diseases, floods and droughts, etc. Use of cryopreserved gametes, embryos, and tissues is a more common form of ex situ conservation. According to FAO (2013), there are 1750 genebanks globally conserving 7.4 million accessions of PGR (FAO, 2013). Plants. This poses a high risk of genetic changes and may cause genetic erosion. Balmford A, Leader-Williams N, Green MJB (1995) Parks or arks: where to conserve threatened mammals? In vitro conservation: Plants can also be conserved in the form of tissues, embryos or cells in vitro. 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. The main objective of ex situ techniques is to support conservation by ensuring the survival of threatened species … Home Conservation Ex Situ. 4: 446. There are more than 800 professionally managed zoos around the world with about 3000 species of mammals, birds, reptiles and amphibians. 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 It is one of two basic conservation strategies, alongside in-situ conservation. Yurjev of UAAS, Kharkiv, Instituto de Investigaciones Agropecuarias, C.R.I. 2, pp. Produce material for conservation biology research. Hari D. Upadhyaya, ... Shailesh Kumar Singh, in Genetic and Genomic Resources for Grain Cereals Improvement, 2016. This chapter provides a comprehensive account of the domestication process of the African giant rat, starting from trapping the wild forms from the forest and savanna of West Africa. Techniques vary according to the characteristics of the species to be preserved, which dictates the type of material to be preserved (e.g. The stresses on living organisms due to competition for food, water, space etc. 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). However, for many species, field genebanks remain the only available form of ex situ conservation. 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. The lentil germplasm accessions with ICARDA have been obtained from 113 global collection missions, and they include 1734 cultivated and 374 wild accessions. Oryx 39:95–98, Ex-situ institutions and their contribution to in-situ conservation, CBD (1992) Convention on Biological Diversity. By continuing you agree to the use of cookies. The European-based EURISCO system provides information about the ex-situ plant collections maintained in Europe (http://eurisco.ecpgr.org/). 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. The major collections of crop species were carried out in the region of the “Fertile Crescent” in Western Asia, where the lentil was domesticated. 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. ), 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. 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. Ex-Situ Conservation 2. This article outlines why conservation is needed, the major threats to species, and how diversity is maintained at the ecosystem, species, and genetic levels. Ex-situ techniques include: seed storage, captive … Secretariat of the Convention on Biological Diversity, Montreal, Canada, Bowkett AE (2009) Recent captive-breeding proposals and the return of the ark concept to global species conservation. Twenty years ago, the need for an integrated system for conserving genetic resources for crop breeding was highlighted (Wood and Lenne, 1997). Ex-situ techniques include: seed storage, captive … In the developed nations, farm parks have increased in popularity and often contribute to meaningful maintenance of biodiversity through their … Convention on Biological Diversity (CBD) 1992 1. 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. Nigel Maxted, in Encyclopedia of Biodiversity (Second Edition), 2013. Losses of genetic diversity in living populations can thus, if necessary, be restored by use of sperm from males of past generations. A study on in-situ and ex-situ gap analysis using taxonomic, ecological, geographic, and conservation information for 672 wild accessions obtained from the global gene bank of ICARDA was carried out by Maxted et al. Major genebanks conserving germplasms of proso, barnyard, kodo, and little millets worldwide*. In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. Ex-situ Conservation. By comparison, ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. Make available material for conservation education and display. Storage of sperm from a wide sample of males of a breed provides future access to the genetic material of these representative foundation animals. Manag. 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. Ex-situ conservation Ex situ or ‘off-site’ conservation means the conservation of components of biological diversity outside their natural habitats.

Cryopreservation: For longer term conservation, plant explants can be cryopreserved directly in liquid nitrogen at −197 °C. The mountain chicken is a Critically Endangered frog found only on Montserrat and Dominica and is the largest native amphibian in the Carribean. 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. It involves the conservation of living organisms outside their ecological niche. (a. However, collection of embryos for cryopreservation is more difficult and expensive than collection of sperm cells and yields of embryos are much lower, often on the order of only 2–8 embryos per mating. Ex situ conservation methods for vegetatively propagated woody species traditionally relied on field or glasshouse collections. the reintroduction of the Arabian oryx to Saudi Arabia 10. Island Press, Covelo,USA, WAZA (2005) Building a Future for Wildlife - The World Zoo and Aquarium Conservation Strategy. It is one of two basic conservation strategies, alongside in-situ conservation. Several companies offer cloning services on a commercial basis, but with a focus on unique, high-value individuals rather than populations. 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. Genet., 76, 399–409. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Field genebanks: Seeds that cannot be dried or do not tolerate low temperatures are termed recalcitrant (Berjak and Pammenter, 2004). This typically involves the designation of protected areas of land as either nature reserves or national parks Title: Ex Situ conservation 1 Ex Situ conservation 2 Ex situ conservation.
