Abstract

This study used numerical analysis to evaluate Enhalus acoroides seed and fruit dispersal in the northwestern sea area of Iriomote Island, Japan. Input data for numerical simulations were provided based on results of an ecological investigation of Enhalus acoroides and field observations of physical phenomena. Reproductions of coastal currents in the northwestern sea area of Iriomote Island were conducted using an ocean current model: CCM. Enhalus acoroides seed and fruit dispersal characteristics were examined using particle tracking analysis.

The simulation used for this study used river flow rate data on the Urauchi River, the Nakara River, and the Kuira River measured by Osamu Watanabe with the Iriomote Project, Research Institute for Humanity and Nature (RIHN). Field surveys for this study were conducted through cooperation of Michiru Tamamoto, Ayaka Iwasaki, Toshie Kuramochi, and Natsumi Kawada who were then students of School of Marine Science and Technology, Tokai University. The authors extend their deepest gratitude for that kind support.
