65th World Aassociation Zoos Aquariums Annu. Other plants simply do not produce seeds and are vegetatively propagated, for example, yams, potato, cassava and aroids. 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). That is, the conservation of selected plants and animals in selected areas outside their natural habitat is known as ex-situ conservation.

Supply material for various purposes to remove or reduce pressure from wild collecting. Ex-situ techniques target plant and animal populations. In vitro conservation: Plants can also be conserved in the form of tissues, embryos or cells in vitro. Proc. Cryopreserved sperm are ideally suited to support in situ conservation activities. 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. However, for many species, field genebanks remain the only available form of ex situ conservation. Techniques vary according to the characteristics of the species to be preserved, which dictates the type of material to be preserved (e.g. 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 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 … 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. 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. In situ and ex situ conservation focuses on the maintenance of species diversity within or away from their natural habitats, respectively. Col. Ger. In the NATP projects, an effort for exploration and collection of lentil germplasm was intensified. 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. Ex-Situ Conservation 2. 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. 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. Grow those species with recalcitrant seeds that cannot be maintained in a seed store. Seed gene banks make the easiest way to store germplasm of wild and cultivated plants at low temperature. Convention on Biological Diversity (CBD) 1992 1. The successes reported here on the domestication of two West African rodents by the author (the African giant rat and the grass cutter) are Africa’s latest contributions to the world of domesticated animals for sustainable meat production. Many of these zoos have well-developed captive breeding programmes.

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. 2020; 9(4):446. Captive breeding followed by re-introduction is a possible approach for endangered species conservation and preservation of geneti … Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Ex-situ (‘off site’) conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat. 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. This was achieved most conveniently by employing reduced temperatures and was carried out initially with herbaceous crops. There are two Methods of biodiversity conservation. By comparison, ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. 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. 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.

DNA material is now becoming the most requested material from genebanks for molecular genetics and genomics studies (Andersson et al., 2006). Since its inception, systematic explorations have been conducted to augment lentil germplasm; area-specific and trait-specific collection trips were also undertaken. Seeds are conserved for > 50 years without any loss of viability (Usberti and Gomes, 1998). 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. This type of in vitro conservation is done in liquid nitrogen at a temperature of −196°C. Some species are however more susceptible to captive-breeding programs than others. 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. A significant advantage in plant conservation is that seeds can be collected for a vast majority of plants. This protects the species from predation and pressure from the environment. The main objective of ex situ techniques is to support conservation by ensuring the survival of threatened species … Wild Lentil Germplasm Accessions Conserved Ex Situ With the Global Collection Held by ICARDA and USDA-ARS. Island Press, Covelo,USA, WAZA (2005) Building a Future for Wildlife - The World Zoo and Aquarium Conservation Strategy. 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 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 is the most convenient, cost effective, and widely used method of conservation. 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. Seeds of lentils are generally orthodox in nature, and can be dried to a lower moisture content of ± 6% with minimum loss of viability. 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. 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). Institutions make the most out of their ex-situ collections by using them in the wider spectrum of conservation activities, ie. Globally, about 1.1 million germplasm accessions of grain legumes are conserved in various gene banks. V.Y. Ex-situ techniques include: seed storage, captive … 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. Title: Ex Situ conservation 1 Ex Situ conservation 2 Ex situ conservation. 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 techniques applicable to animal populations include the storage of embryos, semen/ovule/DNA, or captive breeding through the establishment of field gene banks and livestock parks. 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. 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. Seeds are stored at sub-zero temperature for maintaining viability for decades. 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. 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). 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. Make available material for conservation education and display. Breeding populations in zoos, game farms, aquariums, botanical gardens, arboretums, seed banks 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. Home Conservation Ex Situ. Fig. 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. FAO (2013) has developed international standards for the management of the different kinds of genebanks (seeds, field, in vitro and cryopreservation). Moreover, they are very vulnerable as the germplasm is exposed to changing climatic conditions, pests and diseases, floods and droughts, etc. Ex Situ. 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. Populations on both islands have been devastated by the amphibian chytrid fungus, first on Dominica from 2002 and subsequently from 2009 on Montserrat. The base collections are regularly monitored for seed viability at an interval of 10 years. Ex-situ techniques include: seed storage, captive breeding, slow-growth storage, DNA storage. The efficiency of use of sperm cells to restore a breed depends on the generation time and the fecundity of the species. 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. Source: http://www.fao.org/wiews-archive/germplasm_query.htm. This article outlines why conservation is needed, the major threats to species, and how diversity is maintained at the ecosystem, species, and genetic levels. This is a method of ex-situ conservation of threatened and endangered species in their respective regions. 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. 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. The mountain chicken is a Critically Endangered frog found only on Montserrat and Dominica and is the largest native amphibian in the Carribean. Cryopreservation and subsequent in vitro fertilization of ova are not yet practical for domestic species. However, not all kinds of seeds can be conserved in seed banks. International Union for the Conservation of Nature, Gland, Switzerland, BGCI (2012) International Agenda for Botanic Gardens in Conservation: 2nd edition. Both in situ and ex situ methods of biodiversity conservation are equally important. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. Global status of small millet germplasm maintained in different genebanks. Use of cryopreserved gametes, embryos, and tissues is a more common form of ex situ conservation.

This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. 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. 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. Such strategies are, for example, in use to tackle the global tortoise extinction crisis  11. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. 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). Landmark research for pulses improvement. Ex-situ techniques include: seed storage, captive … 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). Resour. It offers less mobility to the animals as it is smaller in area than the area of in-situ conservation. Ex situ conservation is the widely used method to conserve millet genetic resources. CONSERVATION OF BIODIVERSITY Protecting the loss of Biodiversity. One major advantage of restricted growth techniques is that they utilize the same basic facilities as micropropagation. Its primary objective is to support conservation by ensuring the survival of threatened species and the maintenance of associated genetic diversity. The whole conservation status of wild species in ICARDA gene bank is given in Table 3.1. Nigel Maxted, in Encyclopedia of Biodiversity (Second Edition), 2013. Ex situ management is an important conservation tool that allows the preservation of biological diversity outside natural habitats while supporting survival in the wild. Peter Wyse Jackson, Lucy A. Sutherland, in Encyclopedia of Biodiversity (Second Edition), 2013. 3.1). Hari D. Upadhyaya, ... Shailesh Kumar Singh, in Genetic and Genomic Resources for Grain Cereals Improvement, 2016. In situ conservation, on the other hand, requires conservation efforts to be focused on protecting species in their natural ecosystem. Such strategies include Shoot tip culture methods were modified to slow down growth rates and hence reduce maintenance costs. 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 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). Because our natural systems face many threats, conserving them is not easy, and must use many techniques. Biol Conserv 141:355–363, Griffiths R, Pavajeau L (2008) Captive breeding, reintroduction, and the conservation of amphibians. Major genebanks conserving germplasms of proso, barnyard, kodo, and little millets worldwide*. While in field gene banks, preservation of genetic resources is being done under normal growing conditions. It involves the conservation of living organisms outside their ecological niche. Ex situ conservation means conservation which takes place off-site. 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. Zoological parks, botanical gardens and wildlife safari parks serve this purpose. Academic Press, San Diego, USA, pp 683–695. In cryopreservation, the material can be stored for a considerable long period of time in compact low maintenance refrigeration units. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Bulk up germplasm for storage in various forms of ex situ facility. Maxted N (2001) Ex Situ, In Situ Conservation. 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.

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. The most widely used technique for legume species conservation is seed storage in gene banks, because legume seeds are generally known to be desiccation and freeze tolerant (Hong et al., 1998). Lentil Germplasm Accessions Conserved Ex-Situ at NBPGR New Delhi. Field genebanks: Seeds that cannot be dried or do not tolerate low temperatures are termed recalcitrant (Berjak and Pammenter, 2004). 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. Biorepositories such as gene banks have an explicit ex-situ mandate. Ex situ conservation is a conservation method where the plant or animal species is conserved outside of their natural habitat. Several high-profile case studies have demonstrated that ex-situ conservation measures can play a critical role in preventing species extinction, e.g. Nikhil Malhotra, ... Rahul Chandora, in Lentils, 2019. Many of these botanic gardens now have seed banks, tissue culture facilities and other ex-situ technologies. Lentil. Use of cloning to support conservation of rare breeds will be discussed in the section Advances in Cloning. 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. ), Genetic and Genomic Resources of Grain Legume Improvement.

These plant explants are disinfected and placed in a sterile culture (solutions or agar containing necessary nutrients, hormones and microelements needed for plant survival). This is a crucial conservation method for endangered species. through the production and assimilation of material for research, conservation education 12 and capacity-building 13. The conservation of components of biological diversity outside their natural habitats. According to FAO (2013), there are 1750 genebanks globally conserving 7.4 million accessions of PGR (FAO, 2013).
