9410336 Hay The study of plant-herbivore interactions in freshwater communities has lagged far behind similar investigations in terrestrial and marine systems. Yet research in the latter two habitats has revolutionized our understanding of plant-animal interactions, ecosystem function, and coevolution. This project extends methods and approaches developed for marine herbivore systems to little-studied freshwater herbivore systems. The investigators are documenting: what plant traits deter herbivore consumption, the selectivity of freshwater herbivores, and the impact of generalist vs. specialist herbivores. This research will allow the testing of important theories of plant defenses and herbivory developed in terrestrial and marine systems, and provide a unique opportunity for valuable comparisons between the three systems. This research will improve our understanding of the ecology of plant-herbivore interactions and the role of macrophyte feeders in the function of aquatic ecosystems. The results have application in the management of aquatic ecosystems.

9410336 干草 对淡水群落中植物与食草动物相互作用的研究远远落后于陆地和海洋系统中的类似调查。 然而，对后两个栖息地的研究彻底改变了我们对动植物相互作用、生态系统功能和共同进化的理解。 该项目将针对海洋食草动物系统开发的方法和途径扩展到很少研究的淡水食草动物系统。 研究人员正在记录：哪些植物特征阻碍了食草动物的消费，淡水食草动物的选择性，以及通才与专长食草动物的影响。 这项研究将能够测试陆地和海洋系统中发展的植物防御和食草的重要理论，并为这三个系统之间的有价值的比较提供独特的机会。 这项研究将提高我们对植物与草食动物相互作用的生态学以及大型植物饲养者在水生生态系统功能中的作用的理解。 研究结果可应用于水生生态系统的管理。
