Collaborative Research: Manipulation of N and Water Availability, Belowground Production of Plant Secondary Metabolites, and Ecosystem Processes

华盛顿大学和新墨西哥大学之间的合作研究工作是在这一为期一年的研究奖的基础上启动的。这项研究将结合同一地点正在进行的两项研究，并提供一个独特的机会来开展研究，从而对森林生态系统进行地上和地下的广泛分析。目前的研究是关于操纵资源可获得性(水和/或氮)对地上和地下组织初级生产和次生代谢产物之间碳分配的几个方面的影响的假设。这一为期一年的提案中的初步研究将允许设计实验，以测试操纵资源可用性如何导致以下方面的变化：地上和地下生物量、细根周转、细根生产的季节模式、从衰老组织中吸收养分、叶和根中次生代谢物的质量和数量以及菌根生物量和周转。这些变化应该影响到草食、分解和净生态系统生产的生态系统过程。合作的调查人员拥有出色的个人记录，并以在合作环境中表现良好而闻名。设施一流，实地研究场地也是如此。

A collaborative research effort between the University of Washington and University of New Mexico is initiated with this 1- year research award. The research will combine two ongoing studies on the same site and provide a unique opportunity to develop research leading to an extensive analysis above- and belowground for a forest ecosystem. The current studies are hypotheses concerning the effects of manipulating resource availability (water and/or nitrogen) on several aspects of carbon allocation between primary production and secondary metabolites for above- and belowground tissues. The preliminary research in this 1-year proposal will allow the design of experiments to test how manipulating resource availability should cause shifts in: above- and belowground biomass, turnover of fine roots, seasonal patterns of fine root production nutrient resorption from senescing tissues, quality and quantity of secondary metabolites in foliage and roots, and mycorrhizal biomass and turnover. These changes should affect ecosystem processes of herbivory, decomposition, and net ecosystems production. The collaborating investigators have excellent individual records and are known to perform well in a collaborative context. Facilities are excellent as is the field research site.
