| Research Abstract |
Evaluating the effect of global environmental changes for the distribution and growth of both endemic and universal primary producers. The universal seagrass, Zostera marina was distributed at shallower sites compared to the endemic seagrass species, Z. caespitosa. Electron transfer rate calculated from fluorescence value of seagrass leaves were significantly larger than that of Z. caespitosa. Devices to evaluate effects of both global warming and ocean acidification simultaneously were developed. The result of the manipulative experiment using this device revealed the tendency that Z. caespitosa was less tolerant against the high water temperature than the Z. marina.
