U.S.-New Zealand Planning Visit: Plant and Ecosystem Responses to Global Change

[0627890]该奖项支持计划访问，使芝加哥伊利诺伊大学的Hormoz BassiriRad博士能够与新西兰北帕默斯顿农业研究有限公司的Paul Newton博士会面。greserach是一家独立的、国有的研发公司。他们向财政部长和皇家研究院部长报告。此次访问将促进制定一项关于植物和生态系统应对全球变化的合作计划。除非采取大幅度的减排措施，否则到21世纪末，大气中的二氧化碳浓度将是目前水平的两倍。考虑到二氧化碳对植物生长发育的重要性，有相当大的努力来预测原生植被在预计的二氧化碳上升中的命运。在整个植物水平上，对大气CO2增加的响应是根和茎之间协调相互作用的一系列复杂过程的产物。植物对碳和氮的代谢是如此紧密地联系在一起，以至于其中一个的吸收和同化的任何变化都可能影响另一个的吸收和同化。这个领域的知识状态是高度“描述性”的，预测模型的开发远远落后。这些合作者将处理开发更可靠的机制模型所需的参数，这些模型旨在预测陆地植被的未来命运。新西兰独特的环境（短期操作实验和长期二氧化碳天然温泉的结合）是该项目的理想条件。预计该项目将为美国博士后和研究生提供独特的培训和教育机会，以获得全球研究经验。预计来自每个国家的科学家和学生之间的这些合作将导致长期合作，这将使所有机构受益。

0627890BassiriRadThis award supports a planning visit to enable Dr. Hormoz BassiriRad at the University of Illinois in Chicago to meet with Dr. Paul Newton at AgResearch Limited in Palmerston North, New Zealand. AgReserach is an independent, Crown-owned research and development company. They report to the Minister of Finance and the Minister of Crown Research Institutes. The visit will facilitate development of a collaborative plan on plant and ecosystem responses to global change.By the end of the 21st century, atmospheric CO2 concentration will be double the current levels unless dramatic emission reduction measures are implemented. Given the importance of CO2 for plant growth and development, there is considerable effort to predict the fate of native vegetation to this projected rise in CO2. Responses to increased atmospheric CO2 at the whole plant level are the product of a complex set of processes that result from coordinated interaction between root and shoot. Plant metabolism of carbon and nitrogen are so tightly linked that any change in uptake and assimilation of one is likely to affect the uptake and assimilation of the other. The state of knowledge in this area is highly "descriptive" with predictive model development lagging far behind. The collaborators will address parameters that are needed for the development of more robust mechanistic models designed to predict the future fate of terrestrial vegetation. The availability of a unique setting (combination of short-term manipulative experiments and long-term CO2 natural springs) in New Zealand is an ideal situation for the project. It is also anticipated that this project will provide unique training and educational opportunities for a U.S. postdoc and graduate student to obtain a global research experience. It is anticipated that these collaborations between the scientists and students from each country will lead to long-term collaborations that will benefit all the institutions.
