46. Plant genetic diversity in tropical lowland rainforest transformation systems

Tujuan Penelitian : Mempelajari konsekuensi dari perubahan hutan hujan pada level keanekaragaman intraspeciic Bidang Penelitian : Biologi Daerah Penelitian : Jambi TN Bukit Dua Belas dan Hutan Harapan Lama Penelitian : 12 dua belas bulan mulai 12 Juli 2013 Mitra Kerja : IPB - Prof. Dr. Iskandar Z. Siregar Abstrak The transformation of tropical lowland rainforests to other types of land use has considerable impacts on biodiversity levels and patterns at diferent spatial scales from local to global. Losses of plant species diversity along gradients of increasing land use intensity are well documented, but the consequences of rainforest transformation have rarely been studied at the level of intraspeciic diversity. Population genetic theory predicts losses of genetic diversity as a consequence of fragmentation and small remnant populations. Intraspeciic genetic diversity is a fundamental aspect of biodiversity and a main resource for adaptation to environmental change. The aim of this project is to study the consequences of rainforest transformation at the level of intraspeciic diversity and to assess intraspeciic diversity in diferent transformation systems by the investigation of dominant vascular plant species with diferent taxonomic and phylogenetic positions and life history traits growth forms, mating systems longevity, etc.. Comparing the results to other aspects of biodiversity investigated by other groups will allow investigating trade ofs between intraspeciic diversity of vascular plants with other aspects of biodiversity, e.g. plant diversity. The intention is to test the following hypothesis; a decline of species diversity from reference forests to oil palm plantations is mirrored by a decline of intraspeciic diversity of the plant species dominating the respective systems. For DNA extraction leave samples will be taken or if leaves are impossible to sample parts of the bark 77 Sekretariat Perizinan Penelitian Asing Kementerian Riset dan Teknologi DIREKTORI PENELITIAN ASING DI INDONESIA 2013 The leave samples are about a size of 2g and the bark about 1 cm2. Families can not be forseen because the dominant species on each plot will be sampled.
