Description: Das Projekt "Influence of landscape change on population structure of black-backed Swamphen (Porphyrio indicus) in Java island, Indonesia" wird vom Umweltbundesamt gefördert und von Universität Freiburg, Forstzoologisches Institut, Professur für Wildtierökologie und Wildtiermanagement durchgeführt. Landscape changes may influence population persistence and genetic diversity of black-backed Swamphen (Porphyrio indicus) in Java Island. The changes occurred rapidly, particularly in the coastal area, due to human population pressure. It may affect negatively the quality and compactness of natural ecosystems, particularly wetlands. In turn, it may lead to a reduction of critical resources and impair individual movement. The effect will be severe particularly for wetland-breeding specialist with poor flight capability like in black-backed Swamphen. It is reasonable that some local ornithologist warn about the bird species persistence. Limited information on its behavior and biology make the conservation efforts even more difficult. The species cryptic behavior impedes direct observation for habitat and movement studies, whereas fraught classification makes information on their population size and distribution debatable. Limited reliable information on these aspects may pose an obstacle to conserve their natural population in a rapidly changed environment. Information on population structure and the individual movement between sub populations are central for species conservation in a changing landscape. The project will address some important questions about the effect of the changes on population isolation and its suspected causes, rate of dispersal necessary to maintain genetic diversity, and biased dispersal. A new approach combining molecular genetic and GIS techniques may provide such information and may overcome the lack of direct observations. As guidance for data collection and analysis, general research question is defined as follows: 'How do landscape feature influence individual movement between population of Porphyrio indicus in Java Island ?' Following it, some sub questions may arise: What are the landscape structure and composition in past and recent years? How populations are spatially structured in recent and past years? Is there any evidence of individual exchange between subpopulations? Which landscape features are supposed to facilitate and inhibit individual exchange? Which landscape features do explain population structure better? Several work steps are planned: field work for collecting genetic material, laboratory work for isolation-amplification-analysis of DNA fragments, and desk work for landscape analysis. Raw genetic data of and landscape features will be combined to address the research questions.
