Schulz00-00617This project will examine the potential of plant elemental nutrient content, specifically the ratios of Carbon to Nitrogen to Phosphorus (C:N:P) to cause ecological bottlenecks for susceptible life stages of herbivores. This study is designed to examine a predicted life history constraint posed by the C:N:P content of phytoplankton on aquatic herbivores. Specifically, the study will address the questions: (1) Do the differing nutritional contents of various copepod life stages result in different C:N:P requirements during the life spans of these organisms, and are stages requiring high phosphorus content food a potential bottleneck in the development of copepod populations?; and (2) Can selective feeding by copepods, superior to that of other planktonic taxa, allow these organisms to consume high quality food particles and mitigate nutrient imbalances? Results will be broadly applicable in a biogeographic sense (copepods are very cosmopolitan, inhabiting arctic, temperate, and tropical lakes, as well as oceans) and in a life history comparison with other organisms, such as insects, for which food quality has been incorporated into optimal foraging models.

Schulz 00 - 00617本项目将研究植物元素营养含量的潜力，特别是碳、氮、磷（C：N：P）的比例，以引起食草动物敏感生命阶段的生态瓶颈。 本研究的目的是探讨预测的生活史约束所造成的C：N：P含量的浮游植物水生草食动物。具体而言，本研究将解决以下问题：（1）桡足类不同生命阶段营养成分的差异是否导致这些生物在生命周期中对C：N：P的不同需求，以及需要高磷含量食物的阶段是否是桡足类种群发展的潜在瓶颈？桡足类的选择性摄食是否上级其他浮游类群，使这些生物能够消耗高质量的食物颗粒并减轻营养失衡？ 结果将是广泛适用于在一个apneographic意义上（桡足类是非常世界性的，居住在北极，温带和热带湖泊，以及海洋），并在生活史比较与其他生物，如昆虫，食物质量已被纳入最佳觅食模型。
