Abstract: Genetic diversity is one of the three forms of biodiversity recognized by the World Conservation Union ( IUCN ) as deserving conservation. Genetic diversity, phylogeny and conservation of the Javan rhinoceros (Rhinoceros sondaicus) The need to conserve genetic diversity within populations is based on two arguments: the necessity of genetic diversity for evolution to occur, and the expected relationship between heterozygosity and population fitness. �L�%pO�&���*C"*)D���ZU��v bj�G6��s�X����C��e��I�Ov^�L ��5_\>�]7��t��_q+�%�䍬K0�U8�+����Ǎ��|u�I�8��3��Nm3�S��"��X�~ΐ���{���&�����K7.

Biodiversity refers to variation within the living world, while genetic diversity represents the heritable variation within and between populations of organisms, and in the context of this paper, among plant species.

These losses are often manifestations of degradation or destruction in the ecosystem or habitat.4 According to the Food and Agriculture Organization of the United Nations (FAO), it is estimated that about three-quarter of the genetic diversity in agricultural crops have been lost over the last century due to various reasons su… In the scientific effort for conservation of biodiversity, there has often been an emphasis on the importance of genetic factors in influencing extinction [3]. 30 p.

A perusal of genetic diversity within and among strains indicated that . IPGRI’s Furthermore, even if information on intrapopulation genetic diversities is available, the objectives for the conservation of intrapopulation genetic diversity might conflict with conservation objectives at higher levels of the biological hierarchy such as species diversity … 16 23

CGN maintains genetic diversity in gene bank collections (ex situ) and stimulates the sustainable valorisation of genetic diversity in agriculture and forestry. Metrics of diversity are also relevant for conservation, as populations with high levels of genetic diversity are expected to exhibit longer persistence, as there is more standing variation for selection to act on (Table 2; Hoffmann et al., 2015; Reed and Frankham, 2003). Many conservationists would argue that the conservation of genetic diversity is the foundational basis of all conservation efforts because genetic diversity is requisite for evolutionary adaptation, and such adaptation is the key to the long-term survival of any species (Schemske et al.
