Red tides in Masan Bay, Korea in 2004-2005: II. Daily variations in the abundance of heterotrophic protists and their grazing impact on red-tide organisms
To investigate the role of heterotrophic protists in the dynamics of red tides in Masan Bay, Korea, we measured the abundance of heterotrophic dinoflagellates, ciliates, and heterotrophic nanoflagellates in daily samples collected from June 2004 to May 2005. The abundance of heterotrophic dinoflagel...
