在高营养、低叶绿素（HNLC）区域的研究表明，铁有效性的增加导致浮游植物生物量的增加和群落组成的变化。在这里，我们展示了通过流式细胞术增加或减少铁（Fe）的可用性以监测浮游植物个体群体（大型真核生物，微真核生物和蓝藻）的反应的实验，在秘鲁附近的南美东部边界洋流的封闭群落中添加（0.5至5.0 nM的铁）和减少可用铁（通过添加1至10 nM的真菌铁元素去铁胺B）。周围溶解铁的浓度是多少
Studies in high nutrient, low chlorophyll (HNLC) regions have demonstrated that increased Fe availability results in an increase in phytoplankton biomass and changes in community composition. Here we present experiments in which the availability of iron (Fe) was increased or reduced to monitor the response of individual groups of phytoplankton (large eukaryotes, picoeukaryotes and cyanobacteria) by flow cytometry, Additions (0.5 to 5.0 nM Fe) and reductions in available Fe (through addition of 1 to 10 nM of the fungal siderophore desferrioxamine B) were made to enclosed communities from the South American eastern boundary current off Peru, where ambient dissolved Fe concentrations were
