Dynamic energy budget (DEB) models describe the rates at which individual organisms assimilate and use energy and essential elements such as carbon, nitrogen and phosphorus. The resulting (DEB) theory offers a powerful theoretical framework for relating suborganismal (biochemical, genetic, and physiological) processes to organismal performance (growth, reproduction, mortality), and thereby to ecological and evolutionary change. This project will explore the consequences at many levels of biological organization of a broad range of biochemical and physiological control mechanisms. There will be parallel efforts at developing new, general theory and on one particular application: the biology of stony corals. In that system, the interactions of a host, its symbionts and both intra-cellular and extracellular microbial communities create a context where traditional distinctions between levels of biological organization fail, and where the time scales of physiological, ecological, and evolutionary processes overlap. This new theory will have wide biological and ecological applicability. Potential users of the new approach include the Long-Term Ecological Research (LTER) community within the United States who require theory to compare and contrast critical biological processes at many levels of organization, both within and among sites. There are detailed plans for close collaboration with researchers at the Moorea Coral Reef LTER. There are distinctive educational opportunities deriving from the collaboration between researchers at a research university (University of California, Santa Barbara) and a teaching oriented, minority-serving institution (California State University Northridge). These include cooperative efforts in graduate student training, new modules for undergraduate classes, and the direct involvement of minority students in developing new theory and its empirical tests.

动态能量预算（DEB）模型描述了个体生物体吸收和使用能量以及碳、氮和磷等基本元素的速率。 由此产生的 (DEB) 理论提供了一个强大的理论框架，用于将亚有机体（生化、遗传和生理）过程与有机体性能（生长、繁殖、死亡率）联系起来，从而与生态和进化变化联系起来。该项目将探讨广泛的生化和生理控制机制在生物组织的许多层面上的后果。 我们将同时努力发展新的一般理论和一个特定的应用：石珊瑚的生物学。在该系统中，宿主、其共生体以及细胞内和细胞外微生物群落的相互作用创造了一个环境，在该环境中，生物组织水平之间的传统区别失效，并且生理、生态和进化过程的时间尺度重叠。这一新理论将具有广泛的生物学和生态学适用性。 新方法的潜在用户包括美国的长期生态研究（LTER）社区，他们需要理论来比较和对比组织内部和站点之间多个组织层面的关键生物过程。与莫雷阿珊瑚礁 LTER 的研究人员密切合作有详细的计划。 研究型大学（加州大学圣塔芭芭拉分校）和以教学为导向的少数族裔服务机构（加州州立大学北岭分校）的研究人员之间的合作提供了独特的教育机会。其中包括研究生培养方面的合作、本科生课程的新模块以及少数民族学生直接参与新理论及其实证检验的发展。
