Joint analysis of small-scale movement patterns of coral reef ishes”

113 Sekretariat Perizinan Penelitian Asing Kementerian Riset dan Teknologi DIREKTORI PENELITIAN ASING DI INDONESIA 2013 Cone snails within the genus Conus are a group of marine gastropods that display an impressive amount of species richness in the Indo-West Paciic and have been identiied as an exceptional radiation in the sea. Evolutionary relationships and diversiication dynamics of this group are not well understood due to poorly reined phylogenies. Therefore, I propose to collect samples from 1 Maluku, 2 North Maluku, 3 West Sumatera, 4 Bangka-Belitung, and 5 Bali over the course of 3 months to construct a phylogeny of this group. Then, I will use a comparative phylogenetic approach to understand how and when this staggering diversity evolved. All samples collected will be transported to Denpasar, Bali for genetic analyses.

66. Joint analysis of small-scale movement patterns of coral reef ishes”

Tujuan Penelitian : Memperoleh pemahaman yang lebih baik tentang hubungan antara species dengan habitatnya dan konektiitas fungsionalnya di bentang laut dengan menggunakan pendekatan terpadu menggunakan quantitative movement studies yang berbasis individual based modeling Bidang Penelitian : Biologi Kelautan Daerah Penelitian : Sulut P. Bangka Lama Penelitian : 3 tiga bulan mulai 22 Juli 2013 Mitra Kerja : Puslitbang Kelautan, Pantai dan Pulau-Pulau Kecil - UNHASProf. Ir. Jamaluddin Jompa 114 Sekretariat Perizinan Penelitian Asing Kementerian Riset dan Teknologi DIREKTORI PENELITIAN ASING DI INDONESIA 2013 The major goal of this study is to better understand species-habitat relationships and functional connectivity in marine seascape by using an integrated approach which combines quantitative movement studies with individual-based modelling IBM. The spatially explicit, multi-species IBM will integrate key life history features of two ecologically and economically important reef ish species representing diferent functional groups and spatial representations of the environment habitat structure. The model will be used to study spatial dynamics of ish populations over time and the inluence of multi-frequency temporal constraints tidal dynamics and diel cycle on migration processes and habitat use patterns. It will capture the link between individual movement and population dynamics as well as the movement responses to changing seascape structures that afect individual performance and, in turn, population-level dynamics. Model-based analysis will therefore help to identify essential habitat properties for key species at speciic location and to anticipate responses to changing seascapes and new environmental conditions. Potential scenarios that will be investigated are habitat destruction and changes in resource use. Model results will thereby contribute to the development of both ecological theory about functional connectivity and spatial population dynamics as well as efective conservation strategies of MPAs. Due to the lack of detailed data for model parametrisation, a hydro-acoustic telemetry study will be conducted in North Sulawesi, Indonesia to quantify small- scale space use patterns of model species.
