This project will extend the PI's current investigations on chemical mediation of seaweed-herbivore and invertebrate-predator interactions to include: (1) complex interactions of prey nutritional value with chemical and structural prey defenses, (2) an understanding of how larval and spore defenses differ from those of the adult, and why (exposure to different consumers?, increased exposure to UV without adult structures that provide shade?, etc.), and (3) the role of learned aversion by vertebrate versus invertebrate consumers in affecting both prey and consumer dynamics. Because benthic seaweeds and invertebrates play a trophically and ecologically important role in near-shore communities and are rich sources of novel secondary metabolites that function as defenses against consumers and have potential applications as pharmaceuticals, agrochemicals, and growth regulating substances, understanding how these organisms respond chemically to ecological and environmental threats can provide fundamental information about how marine systems function, and can suggest strategies for applied uses of marine natural products.

该项目将扩大PI目前的调查， 海藻-草食动物和无脊椎动物-捕食动物的化学调解 相互作用包括：（1）猎物之间复杂的相互作用 营养价值与化学和结构的猎物防御，（2） 了解幼虫和孢子的防御与那些 的成年人，为什么（暴露于不同的消费者？，增加 暴露在紫外线下，没有成年人的结构，提供阴影？等等）， 以及（3）脊椎动物与 无脊椎动物消费者在影响猎物和消费者 动力学 因为海底海藻和无脊椎动物 在近岸生态和营养方面的重要作用 是新的次级代谢产物的丰富来源 作为对消费者的防御， 医药、农用化学品和生长 调节物质，了解这些生物体如何响应 生态和环境威胁的化学反应， 关于海洋系统如何运作的基本信息， 为海洋天然产品的应用提出战略建议。
