• Response of Energy flow in Algal bed Ecosystems against Ocean Acidification

  Project Period (FY)： 2019/04  -  2023/03  Investigator(s): Wada Shigeki

  We used the CO2 Sheep of Shikine Island to analyze the acquisition of energy through photosynthesis and the fate of the fixed energy. The photosynthetic production of the natural community obtained by deploying attachment substrates was significantly higher in high-CO2 areas, suggesting a fertilization effect on photosynthesis. On the other hand, there was no increase in algal biomass. One possible factor is that the process of algae detachment from the seafloor and transportation is enhanced, leading to the transfer of energy from coastal ecosystems to other ones. Furthermore, when comparing the algal community attached to the seafloor with the algae drifting away, the associated animal communities significant changed, indicating potential effects on higher trophic levels.
