| Abstract | Four Alectoris species inhabit the Mediterranean area, where they represent important gamebirds subject to human manipulations. The Sardinian partridge is peculiar in Europe, in that it belongs to the African species Alectoris barbara. Nevertheless, no comprehensive study has as yet investigated its genetic status as regards both the extant levels of genetic diversity and the possible contamination due to introgressive hybridization with other Mediterranean species. For the purposes of this study, we analyzed 65 samples of Sardinian partridges, 40 of which came from the wild population and 25 from captive stocks. No one of them showed a mtDNA polymerase chain reaction restriction fragment length polymorphism haplotype assigned to another species than A. barbara, thus, ruling out a possible introgression in the maternal line. In addition, we compared these samples with 94 partridges from other circum-Mediterranean populations using a set of eight chicken (Gallus gallus) microsatellites. A low level of genetic variation was observed in the Sardinian population (H E = 0.310; k AR = 2.69), comparable only to that observed in the Sicilian rock partridge (A. graeca). The comparison with the Tunisian population showed that its present genetic composition is consistent with a historical introduction from North Africa, showing possible effects of a post-introductional genetic drift. Bayesian tests assigned all but one individuals with >90% probability to A. barbara, thus, providing evidence that no or only a few exotic Alectoris genes have introgressed into Sardinian partridges. |

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.
