| Abstract | This study focuses on some genetic consequences of habitat fragmentation in populations of four endemic bird species (Monticola sharpei, Terpsiphone mutata, Foudia omissa, andFoudia madagascariensis) living in the understory of forests in the Réserve Spéciale d'Ambohitantely on the Central High Plateau of Madagascar. The four species differ in their dependency on forest habitats, which may be related to their migration abilities between isolated forest fragments. Genetic variation was analysed on the basis of multi-locus fingerprints in order to study the influence of migration and habitat size on the genetic variability of local populations. There was no evidence that forest fragmentation affects any of the four species with respect to genetic variability.Rund 53 % der Vogelarten Madagaskars sind endemisch. Viele dieser Arten sind an Waldhabitate gebunden und durch die Verinselung der madagassischen Wälder hochgradig bedroht. In dem vorliegenden Projekt wird die Auswirkung der Verinselung auf die genetische Variabilität und die genetische Differenzierung von vier endemischen Vogelarten am Beispiel des Reservats von Ambohitantely im zentralen Hochland Madagaskars untersucht. Ambohitantely beinhaltet mehr als 500 Waldfragmente von 0,64 ha bis 1250 ha. Untersucht wurden: 1. die WaldartFoudia omissa, 2.Monticola (früherPseudocossyphus)sharpei, eine Art mit starker Bevorzugung für primäre Waldlebensräume, die aber gelegentlich auch in Sekundärvegetation auftritt, sowie 3.Terpsiphone mutata und 4.Foudia madagascariensis, beides Arten, die sowohl in Wäldern als auch in offenen Landschaften vorkommen. Die unterschiedliche Abhängigkeit dieser Arten von Waldhabitaten und der damit verbundenen Möglichkeit, offene Landschaften zwischen den Waldfragmenten zu überbrücken, führte zur Frage, ob die Verinselung die genetische Vielfalt der untersuchten Populationen beeinflußt. Für die genetischen Analysen wurden Blutproben von Tieren aus drei Gebieten mit 1250 ha, 136 ha und 28 ha gesammelt. Die Proben wurden mit Multilocus-Fingerprints genetisch charakterisiert. Zum Untersuchungszeitpunkt konnte kein Einfluß der Fragmentierung auf die genetische Populationsstruktur der vier untersuchten Arten nachgewiesen werden. |

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.
