This grant will support a synthesis of over 15 years of research by the author on the regulation of carbon and nutrient cycles in ecosystems and will result in a major monograph setting out the foundations of a theory of the optimal use of resources such as carbon, water, and nutrients. The theory predicts how organisms should regulate the acquisition of resources from their environment to maximize growth. This regulation has clear ramifications for ecosystem responses to disturbances like, for example, global warming. The monograph will present the mathematics used by the author in his model of resource optimization and provide illustrative examples. The work has the potential to develop into a broadly synthetic theory of ecosystem regulation that will unify concepts from biogeochemistry, eco-physiology, and community and population biology. This synthesis is aimed directly at education; the monograph and classroom-ready sample simulations could serve as the basis for a modeling course or supplement to an Ecology course. Most quantitative training in ecology is currently focused on statistics, not the dynamics of ecosystem function. However, a strong foundation in dynamics is required for a mechanistic understanding of ecosystems and how they respond to changes in the environment. The products of this synthesis should help establish that foundation for the next generation of ecologists.

这笔赠款将支持作者对生态系统中碳和养分循环调节的15年以上研究的综合，并将导致一本主要专著，阐述碳，水和养分等资源的最佳利用理论的基础。 该理论预测了生物体应该如何调节从环境中获取资源以实现最大增长。 这一规定对生态系统对全球变暖等干扰的反应有明显的影响。 这本专著将介绍作者在他的资源优化模型中使用的数学，并提供说明性的例子。 这项工作有可能发展成为一个广泛的综合生态系统调节理论，将统一的概念，从地球化学，生态生理学，社区和人口生物学。 这一综合是直接针对教育;专着和课堂上准备好的样本模拟可以作为一个建模课程或生态学课程的补充基础。 目前，生态学中的大多数定量培训都集中在统计数据上，而不是生态系统功能的动态。 然而，一个强大的动力学基础是需要一个机械的理解生态系统，以及它们如何应对环境的变化。 这种综合的产物应该有助于为下一代生态学家奠定基础。
