Extensive evidence suggests that resource quantity and quality can have an important influence on zooplankton community structure. Hypotheses developed in this research describe how the resource base of the zooplankton is expected to vary seasonally among systems with differing trophy and differing nitrogen and phosphorus supply ratios. Predictions are made regarding the response of the zooplankton community to these variations in resource base. The preliminary results of experiments conducted this past summer are discussed as they pertain to the proposed hypotheses. Further research is proposed that will allow evaluation virtually all of the components of the resource base and of the zooplankton community to enrichment at high and low TN:TP ratios.

大量证据表明，资源数量和质量可以对浮游动物群落结构产生重要影响。 本研究中提出的假设描述了浮游动物的资源基础在具有不同营养和不同氮磷供应比例的系统中如何随季节变化。 对浮游动物群落对资源基础的这些变化的反应进行了预测。 讨论了去年夏天进行的实验的初步结果，因为它们与所提出的假设有关。 进一步的研究将允许对资源库和浮游动物群落的几乎所有组成部分进行评估，以实现高和低 TN:TP 比率的富集。
