The views, thoughts and opinions expressed in the article belong solely to the author and not to RozBuzz-WeMedia. The establishment of ex-situ of important living plants was started in 1993. Seed Banks: credit: third party image reference. [10] Minimizing the loss of genetic diversity within the captive population is an important component of ex situ conservation and is critical for successful reintroductions and the long term success of the species, since more diverse populations have higher adaptive potential. Ex situ conservation continues to represent the most significant and widespread means of conserving PGRFA. The fragments are maintained separately until inbreeding becomes a concern. CS1 maint: multiple names: authors list (, Cryoconservation of animal genetic resources, Learn how and when to remove this template message, "IUCN Species Survival Commission Guidelines on the Use of Ex situ Management for Species Conservation". conservation, ex situ conservation, ecosystem conservation, species conservation, static conservation, dynamic conservation and others. In choosing individuals for breeding, it is important to choose individuals with the lowest mean kinship values because these individuals are least related to the rest of the population and have the least common alleles. Zoological parks are areas which provide animals with conditions as close as possible to the natural habitats. Endangered animals on the verge of extinction are successfully breeded. Diseases and pests foreign to the species, to which the species has no natural defense, may also cripple crops of protected plants in ex situ plantations and in animals living in ex situ breeding grounds. Smaller populations have lower adaptive potentials, so the population fragments are less likely to accumulate adaptations associated with captivity. In situ conservation is the production and management of important components of biological diversity through a network of protected areas. Ex-situ conservation involves maintenance and breeding of endangered plants and animals under partially or wholly controlled conditions in specific areas like zoos, Gardens, Nurseries, etc. The main objective of this project is to develop representative living collections of trees, palms, bamboo, wild orchids, forest vines, and other groups of forest plants. The Global Plan of Action for Animal Genetic Resources and the Interlaken Declaration. [10] Minimizing selection on captive populations by creating an environment that is similar to their natural environment is another method of reducing adaptations to captivity, but it is important to find a balance between an environment that minimizes adaptation to captivity and an environment that permits adequate reproduction. The downside to this is that, when re-released, the species may lack the genetic adaptations and mutations which would allow it to thrive in its ever-changing natural habitat. It is the process of protecting an endangered species, variety or breed, of plant or animal outside its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, an artificial environment which is similar to the natural habitat of the respective animal and within the care of humans, example are zoological parks and wildlife safaris. FAO Animal Production and Health Guidelines. [9], Genetic diversity is often lost within captive populations due to the founder effect and subsequent small population sizes. are among the most important pasture legumes of temperate regions. Technical limitations prevent the cryopreservation of many species, but cryobiology is a field of active research, and many studies concerning plants are underway. Ex Situ Plant Conservation, edited by Edward O. Guerrant Jr., Kayri Havens, and Mike Maunder, is the first book to address integrated plant conservation strategies and to examine the scientific, technical, and strategic bases of the ex situ approach. 3 Limitations. It includes the collection, preservation and maintenance of selected genetic resources from wild. It is also important to avoid mating two individuals with very different mean kinship values because such pairings propagate both the rare alleles that are present in the individual with the low mean kinship value as well as the common alleles that are present in the individual with the high mean kinship value. It is the process of protecting an endangered species, variety or breed, of plant or animal outside its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, an artificial environment which is similar to the natural habitat of the respective animal and within the care of humans, example are zoological parks and wildlife safaris. Typically species that are either difficult or impossible to conserve in seed banks are conserved in field gene banks. It is therefore important that ex situ and in situ conservation are designed and practiced to reinforce and complement each other. Seed bank facilities vary from sealed boxes to climate controlled walk-in freezers or vaults. Ex situ conservation of Pinus radiata D. Don. It is the conservation, thereby providing conditions necessary for a secure life and breeding. This technique is primarily used for taxa that are rare or in areas where habitat has been severely degraded. Ex situ management is an important conservation tool that allows the preservation of biological diversity outside natural habitats while supporting survival in the wild. One of the most serious gaps is in the area of crops of regional importance, which are not widely traded on world markets. This can be wildlife sanctuaries, national parks, biosphere reserves etc. The main advantage of seed banking is that it allows a large population to be preserved and genetic erosion to be minimized by providing optimum conditions and reducing the need for regeneration. The focus on vertebrates is not solely pragmatic. The storage of seeds, pollen, tissue, or embryos in liquid nitrogen. It needs large tracts of land, Adequate soil conducive weather, etc. [10], Selection favors different traits in captive populations than it does in wild populations, so this may result in adaptations that are beneficial in captivity but are deleterious in the wild. Ex-situ measures should preferentially be put into practice in the country of species origin. These facilities provide not only housing and care for specimens of endangered species, But also have an educational value. It offers less mobility to the animals as it is smaller in area than the area of in-situ conservation. THE IMPORTANCE OF IN SITU CONSERVATION In situ conservation is an important component of the conservation and management of genetic resources. Breeding populations in zoos, game farms, aquariums, botanical gardens, arboretums, seed banks ; When would this approach be desirable or necessary? Ex-situ conservation involves maintenance and breeding of endangered plants and animals under partially or wholly controlled conditions in specific areas like zoos, Gardens, Nurseries, etc. Ex-situ conservation of medicinal plants is a complementary action to conserve the genetic diversity, thereby reducing pressure on wild habitats and augmenting Thousands of tree species depend on conservation outside protected areas than their natural habitats as in managed forests, agricultural landscapes, or ex-situ in botanical gardens, arboreta, seed banks or gene field banks (Theilade, 2003). [9] The high occurrence of genetic disorders within a captive population can threaten both the survival of the captive population and its eventual reintroduction back into the wild. Cryoconservation of animal genetic resources. Ex-situ conservation 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 be a wild area or within the care of humans. A potential technique for aiding in reproduction of endangered species is interspecific pregnancy, implanting embryos of an endangered species into the womb of a female of a related species, carrying it to term. Ex situ conservation in germplasm and living collections is a major focus of global plant conservation strategies. Ex-situ centres offer the possibilities of observing wild animals, which is otherwise not possible. L'échantillonnage, le transfert et le stockage des taxons cibles de leurs habitats naturels … The zoological parks are centres of education and recreation, they also play an important role in the conservation of species such as Manipur Thamin deer and the white winged woo… This occurs with either restored or semi-natural environments. Field Gene Banks: This is a method of planting plants for the conservation of genes. Importance of Germplasm conservation: ... Ex-situ conservation: The genetic materials can be conserved either by collecting plants and kept in normal growing conditions or in the form of seeds in seed banks, through tissue culture and low temp maintained by liquid N 2. [7] It has been carried out for the Spanish ibex. For e.g. Preliminary multiplication 39 C. Storing and conserving germplasm 43 D. Managing the conserved germplasm 63 V. Management of germplasm collections and genebanks 101 A. Germplasm collections 102 B. Genebanks 107 VI. In this management strategy, the captive population is split into several sub-populations or fragments which are maintained separately. 2.
