External Forcing vs. Internal Processing in Two Oligotrophic Lakes

关于小学和初中教育模式的长期（27年）数据集 Castle次级生产力和养分循环动态 湖和太浩湖，加州，将进行分析，以确定 营养物质的生物再循环的相对重要性， 控制湖泊生产力的“新”营养物质的供应。 在 此外，在两个湖泊的有限测量将 以继续长期数据集。 这项新研究的主要成果将是一种概念性的 控制初级和次级生产的因素模型 两个加州湖。 该模型将有助于 设计进一步的科学研究。 同样重要的是，模型 将有助于制定未来的管理战略， 大型湖泊系统，位于流域， 使用变化，如度假村的发展。 戈德曼博士和他的同事们有很长的记录， 高质量的科学，并利用这些科学来帮助解决 社会问题。 研究的机构支持是 好极了 生态系统研究计划建议授予 这个grant。

Long-term (27-year) data sets on patterns of primary and secondary productivity and nutrient cycling dynamics for Castle Lake and Lake Tahoe, California, will be analyzed to determine the relative importance of biotic recycling of nutrients and the supply of "new" nutrients in controlling lake productivity. In addition, a limited set of measurements at the two lakes will be made to continue the long-term data sets. The major product of this new research will be a conceptual model of factors that control primary and secondary production in the two California lakes. This model will be useful for designing further scientific research. As important, the model will be useful for developing future management strategies for large lake systems that are located in watersheds undergoing land use changes such as resort development. Dr. Goldman and his colleagues have long records of doing high quality science and using this science to help solve societal problems. The institutional support for the research is excellent. The Ecosystem Studies Program recommends award of this grant.
