0107360FrancoeurThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will provide 12 months of support to Dr. Steven N. Francoeur to work with Dr. Barry J. F. Biggs at the National Institute for Water and Atmospheric Research in Christchurch, New Zealand. The PI will conduct coupled field and laboratory investigations of the effects of low-intensity flood events on stream periphyton and invertebrates. The overall objectives of this work are to 1) discover patterns in the biotic communities of natural streams related to low-intensity flood events by using time-series sampling and correlative analyses, and 2) test the causal role of low-intensity floods in generating these patterns by conducting manipulative experiments in large, outdoor artificial streams. He expects that low-intensity flood events may cause quite different biological responses than high-intensity floods, perhaps even resulting in increased biomass or productivity. Working in New Zealand with Dr. Biggs provides an ideal setting because of the great number of streams with differing flood regimes in a small geographical area, and they already have an artificial stream facility for experimental work, plus, Dr. Biggs leads a highly productive research team specializing in investigation of the role of flood events in stream ecosystems.

0107360FRANCOEURTHE国际研究员奖计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该计划的奖项为联合研究提供了机会，并在国外使用独特或补充设施，专业知识和实验条件。该奖项将为史蒂芬·N·弗朗西奥（Steven N. Francoeur）博士提供12个月的支持，以与新西兰基督城的国家水研究所的Barry J. F. Biggs博士合作。 PI将对低强度洪水事件对河流周围和无脊椎动物的影响进行耦合的田间和实验室研究。 这项工作的总体目标是1）通过使用时间序列采样和相关分析发现与低强度洪水事件有关的自然溪流的生物群落中的模式，以及2）测试低强度洪水在通过在大型的，户外艺术的大型，户外艺术人工溪流中进行操纵实验来产生这些模式在产生这些模式中的因果作用。 他预计，低强度洪水事件可能会导致与高强度洪水相比，甚至导致生物量或生产力提高。 在新西兰与Biggs博士一起工作，提供了理想的环境，因为在小地理区域中有大量的洪水泛滥的溪流，并且他们已经设有人工溪流设施进行实验性工作，此外，Biggs博士领导了一支高度生产的研究团队，专门研究流媒体生态系统中洪水事件的作用。
