摘要在纽约阿迪朗达克山脉的酸性湖泊中，采用小型围隔（20 L）研究了磷添加和浮游动物去除对浮游植物的影响。尽管无机机制能够在酸性条件下螯合磷酸盐，但在加入80 μg L−1磷酸盐（以KH2PO4形式）后，浮游植物种群大量繁殖。的反应进行了测量的细胞计数的优势phytophytoicter，衣原体和叶绿素a浓度的变化。大约一半的藻类细胞的数量后，两个星期的孵化时，浮游动物没有被删除，表明浮游动物食草可以影响，但不能完全控制，藻类生产。
ABSTRACT Small (20 L) enclosures were used to study the effects of phosphorus addition and zooplankton removal on the phytoplankton of an acidic lake in the Adirondack Mountains of New York. Inspite of inorganic mechanisms which are capable of sequestering phosphate under acidic conditions the phytoplankton population bloomed after the addition of 80 μg L−1 of phosphate as KH2PO4. The response was measured by cell counts of the dominant phytoplankter, Chlamydomonas and changes in chlorophyll a concentration. About half the number of algal cells were present after the two week incubation when zooplankton were not removed, indicating that zooplankton herbivory can influence, but not totally control, the algal production.
