This award supplements a grant supported by an NSF/EPA Award on Water and Watersheds. The research, performed in collaboration with Winfried Lampert of the Max- Planck-Institut for Limnology, seeks to learn how individual zooplankton species respond to the major changes in their algal resources that occur during cultural eutrophication.. The feeding and fitness responses of animals from before and after periods of eutrophication will be studied. Phenotypic and genetic variation in zooplankton populations will be documented using animals hatched from long-lived diapausing eggs collected from lake sediments of different ages. The research will lead to substantially enhanced understanding of how natural populations and communities of freshwater herbivores respond to anthropogenic environmental change.

该奖项是对由美国国家科学基金会/美国环境保护署水和流域奖资助的补助金的补充。这项研究是与马克斯-普朗克湖沼研究所的温弗里德·兰伯特合作进行的，旨在了解单个浮游动物物种如何应对在培养富营养化过程中藻类资源的重大变化。将研究富营养化前后动物的摄食和适应性反应。浮游动物种群的表型和遗传变异将通过从不同年龄的湖泊沉积物中收集的长寿命滞育卵孵化的动物来记录。这项研究将大大提高对淡水食草动物自然种群和群落如何应对人为环境变化的理解。
