| Abstract | Traditionally the distribution of the Arabian oryx in the Kingdom of Saudi Arabia has been closely associated with that of the major sand deserts, notably the Great Nafud in the north and the Rub' al Khali in the south. Due to a successful captive breeding programme the Arabian oryx was reintroduced in the ‘Uruq Bani Ma’arid Protected Area, on the western edge of the Rub' al Khali during 1995, thereby re-establishing the southern population in the Kingdom of Saudi Arabia. Population viability analysis is used to demonstrate the re-establishment of the northern oryx population, the vulnerability of certain populations and to suggest a management approach that should enhance the survival of the free-living populations in the Kingdom of Saudi Arabia. Population models predict that the ‘Uruq Bani Ma’ arid population could be subject to extinction (Psurvival=0.38) when modeled in isolation. Associated with this is a low heterozygosity. The proposed release strategy of oryxes into a northern protected area results in maximum population growth during the first 20-years and continued positive population growth during the 100-year modeling period. The latter free-living population is, however, also subject to extinction due to its relatively small size. By managing all of the Arabian oryx populations in the Kingdom of Saudi Arabia as a single metapopulation, survival of the free-living populations are enhanced, without negatively affecting the other populations.Traditionell ist die Verbreitung der arabischen Oryx im Königreich Saudi Arabien eng verbunden mit der Verbreitung der gro\en Wüstenflächen, insbesondere der Gro\en Nafud im Norden und dem Rub' al Khali im Süden. Auf Grund von einem erfolgreichen Zuchtprogramm von gefangenen Tieren konnte die arabische Oryx 1995 wieder in das Schutzgebiet ‘Uruq Banii Ma’ arid auf der westlichen Seite vom Rub'al Khali eingesetzt werden. Somit wurde die südlichste Population im Königreich von Saudi Arabien re-etabliert. Die Analyse der Lebensfähigkeit der Population dient zur Demonstration der folgenden Gegebenheiten und Ma\nahmen: die Wiederherstellung der nördlichen Oryx Population, die Gefährdung von bestimmten Populationen und den Entwurf von einer Bewirtschaftungsmethode um das überleben der freilebenden Populationen im Königreich von Saudi Arabien zu fördern. Populationsmodelle sagen voraus, dass die ‘Uruq Bani Ma’ arid Population aussterben könnte (Psurvival-0,38) wenn das Modellverfahren auf der Basis einer isolierten Population durchgeführt wird. Damit verbunden ist eine niedrige Heterozygotie. Die vorgeschlagene Freilassungsstrategie von Oryx in einem nördlichen Schutzgebiet ergibt einen maximalen Populationszuwachs während der ersten 20 Jahren und verzeichnet weiterhin einen positiven Populationszuwachs während der gesamten 100 jährigen Modellperiode. Diese letztere freilebenden Population ist wegen ihrer geringen Grö\e jedoch auch vom Erlöschen bedroht. Wenn alle arabischen Oryx-Populationen im Königreich von Saudi Arabien als eine einzige Gro\population bewirtschaftet werden, dann wird die überlebensrate der freilebenden Populationen gefördert ohne die anderen Populationen negativ zu beeinflussen. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
