Macrozooplankton Grazing in a Temperate Fjord

在华盛顿的Dabob湾，浮游植物存量和产量的年循环在春季和秋季表现出惊人的增长（浮游植物大量繁殖），这表明食草动物种群缺乏控制。然而，几乎所有的浮游植物最终都被食草动物消耗掉了。达格博士将测试一个概念模型，该模型假设微观和宏观浮游动物食草物种的身份，并假设浮游植物生长和食草之间的年度平衡机制。这项研究将对假设模型进行实地检验。在四次扩展巡航中建立浮游动物（包括小型和大型浮游动物）的功能动态，并构建碳流预算。放牧率将在野外进行实验测量。

In Dabob Bay, Washington, the annual cycles of phytoplankton standing stock and production rate exhibit spectacular increases (phytoplankton blooms) in the spring and the autumn, indicating a lack of control by the grazer populations. Yet virtually all of the phytoplankton production is ultimately consumed by grazers. Dr. Dagg will test a conceptual model hypothesizing the identities of the micro- and macro-zooplankton grazer species and postulating a mechanism for the annual balance between phytoplankton growth and grazing. This research will field test the hypothetical model. The functional dynamics of zooplankton grazers (both micro and macrozooplankton) will be established on four extended cruises and budgets of carbon flow will be constructed. Grazing rates will be experimentally measured in the field.
