US - Chile Planning Visit: Climate change effects on streamflow from mid-latitude conifer forests: a collaboration between Oregon and Chile

Julie A.琼斯俄勒冈州州立大学OISE-0917697这个美国-智利奖项将支持朱莉娅琼斯博士和一名来自俄勒冈州州立大学的研究生计划访问阿根廷和智利。 访问将于2009年3月进行。 这次访问的主要目的是启动俄勒冈州州立大学的研究人员、智利南方大学的Antonio Lara和Rocio Urruti博士以及阿根廷冰雪和环境研究所的Ricardo Villalba博士之间的长期合作，研究气候变化对中纬度针叶林径流的影响。 具体而言，拟议的研究将检查和对比气候变化对水的可用性（并最终对流生态系统）在中纬度针叶林在海洋西海岸气候在北方和南半球的影响。 在访问期间，研究人员将熟悉拟议的森林流域研究地点，计划实验，并为机构之间的未来合作制定战略。 这次访问有可能导致未来的研究：（1）森林水文学和跨站点比较的成对流域实验，（2）树木年轮年表和气候/水文重建的跨站点比较，在俄勒冈州和智利。 重建过去的森林历史和树木生长对气候的敏感性将使我们能够对未来气候对径流的影响进行可比的预测。

Julie A. JonesOregon State UniversityOISE-0917697This U.S. - Chile award will support Dr. Julia Jones and a graduate student from Oregon State University on a planning visit to Argentina and Chile. The visit will take place in March 2009. The primary goal of the visit is to initiate a long-term collaboration between researchers at Oregon State University, Drs. Antonio Lara and Rocio Urruti from University Austral in Chile, and Dr. Ricardo Villalba from the Argentinean Institute for Snow, Ice and Environmental Research to study climate change effects on streamflow from mid-latitude conifer forests. Specifically, the proposed research will examine and contrast effects of climate change on water availability (and ultimately on stream ecosystems) in mid-latitude conifer forests in marine west coast climates in the Northern and Southern hemisphere. During the visit, the researchers will familiarize themselves with the proposed forest watershed study sites, plan experiments, and develop a strategy for future collaboration between the institutions. The visit has the potential to lead to future studies regarding (1) forest hydrology and paired-watershed experiments with cross-site comparisons, and (2) cross-site comparisons of tree-ring chronologies and climate/hydrology reconstructions, in Oregon and Chile. Reconstruction of past forest histories and tree growth sensitivities to climate will permit us to develop comparable projections of future climate effects on streamflow.
