dc.description.abstract To assess changes in abiotic and biotic factors between flood and ebb tides we investigated the seasonal phytoplankton and bacterial dynamics and environmental conditions along a salinity gradient at 14 stations in the Seomjin River estuary(SRE), Korea. We performed bioassays to identify the effect of additional nutrients (+N, +P, and +NP) on phytoplankton growth and performed high-resolution 16S rRNA tag pyrosequencing to obtain snapshots of the bacterial diversity and community structure along the salinity gradients. Nitrate+nitrite and silicate loading increased as a result of freshwater input, and that phosphates loading may primarily have involved leaching from bottom sediments of the shallow inner bay.Inaddition, we suggested that sufficient N and Si are supplied by river discharges to favor suitable habitat conditions for diatoms, and are a main bottom-up factor affecting phytoplankton blooms during all seasons.(SRE), Korea.
