| Abstract | The Houbara bustard (Chlamydotis undulata) is a threatened avian species that is rapidly declining throughout its range, especially in North Africa, Asia and the Canary Islands. We examined the population structure and genetic variation for the three Houbara subspecies C. undulata undulata, C. u. fuertaventurae and C. u. macqueenii. A total of 266 birds from 10 populations were genotyped using seven polymorphic microsatellite markers. The analysis of microsatellite loci generated 1821 genotypes and 55 different alleles. Estimates of observed and expected heterozygosities were relatively high and ranged from 0.371 to 0.687 and from 0.326 to 0.729, respectively. For the first time, significant phylogeographic structure among Asian Houbara populations was found using neutral nuclear markers. Analysis of molecular variance revealed 12.03% population variability among the subspecies. Population structure and assignment tests inferred using a Bayesian approach revealed two distinct clusters with more than 90% likelihood, one Asian and one North African. A positive correlation between genetic distance and geographic distance was detected among populations (r(2) = 0.302). For conservation purposes, this genetic information will help understand the current genetic status improving management strategies for Houbara bustard breeds and populations. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
