| To understand the effect of nutrient deficiency on the plankton community in three stations with different water qualities in Pal'tang Reservoir, Korea, phytoplanktons(> 10 ${mu}m$) were cultured in nutrient enrichment Allen's media (AM) and nutrient-deficient Allen's media. A distinct shift in the species composition and biomass of phytoplankton (as chlorophyll- a) showed in all treatments. In particular, it was very interesting that the new development of cyanobacterium Microcystis aeruginosa occurred by the Fe-deficient AM. Except for Si, a community growth (as chlorophyll- a) was inhibited in all nutrient deficient treatments. Species diversity after nutrient deficiency was changed to below 2.0; slightly increased in N and P-deficiency, while decreased in Si and Fe, respectively. As suggested, dominance was entirely opposite to diversity. Therefore, the nutrient deficient effectively induced the succession of species and biomass, phytoplankton community, suggesting a possibility as a reliable tool to control the algal bloom in eutrophic lakes and reservoirs. |
