Collaborative Research Manipulation Water Availability

项目摘要

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.

一项合作研究，华盛顿和新墨西哥州的大学是由这个1- 年度研究奖。这项研究将结合联合收割机两个正在进行的在同一地点进行研究，并提供一个独特的机会，开展研究，以进行上述广泛的分析-以及森林生态系统的地下部分。目前的研究是操纵资源效应假说碳的几个方面的可用性（水和/或氮）初级生产和次级代谢物之间的分配地上和地下的组织。初步研究这项为期一年的提案将允许设计实验来测试操纵资源可用性应如何导致以下方面的转变：地上地下生物量，细根周转，季节性细根生产的营养吸收模式，衰老组织、次生代谢产物的质量和数量以及菌根生物量和周转率。这些变化应该会影响草食动物的生态系统过程，分解和净生态系统生产。合作的研究人员具有优秀的个人记录并在协作环境中表现良好。设施是优秀的，因为是实地研究的网站。
