  • 摘要:To understand the effect of nutrient deficiency on plankton communities, phytoplankton (>low) from the Pal'tang Reservoir, Korea, was cultured in nutrient-enriched Allen's media (AM) as well as AM deficient in N, P, Si and Fe (DM). We observed a distinct shift in the species composition and phytoplankton biomass (as measured by chlorophyll a content) when AM and the various DM populations were compared. In Fe-DM (DM lacking iron), the cyanobacterium Microcystis aeruginosa emerged. In all tested DM, except for Si-DM, community growth was inhibited. Species diversity increased slightly in samples cultured with N- and P-DM and decreased in samples grown in Si- and Fe-DM. Therefore, deficiency of certain nutrients effectively decreased phytoplankton species diversity and biomass, suggesting that nutrient depletion might be a potential tool for controlling algal blooms in eutrophic lakes and reservoirs.
