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

0627890BassiriRad 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 AgResearch Limited 的 Paul Newton 博士会面。 AgReserach 是一家独立的皇家研发公司。 他们向财政部长和皇家研究所部长报告。 此次访问将促进制定植物和生态系统应对全球变化的合作计划。到21世纪末，除非采取大幅减排措施，否则大气中二氧化碳浓度将是目前水平的两倍。 鉴于二氧化碳对植物生长和发育的重要性，人们付出了相当大的努力来预测原生植被对二氧化碳预计上升的影响。 整个植物对大气二氧化碳含量增加的反应是根和芽之间协调相互作用所产生的一系列复杂过程的产物。 植物对碳和氮的代谢紧密相连，其中一种物质的吸收和同化的任何变化都可能影响另一种物质的吸收和同化。 该领域的知识状况高度“描述性”，预测模型的开发远远落后。 合作者将解决开发更强大的机械模型所需的参数，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泉水的结合）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。 预计各国科学家和学生之间的合作将形成长期合作，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.
