9901158WilliamsThe 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 Dr. Michael R. Williams with twelve months of support to work with Dr. Luis Antonio Martinelli at the University of Sao Paulo, CENA, in Brazil. Support for this project is provided by the U.S.-Brazil Program.Dr. Williams will be investigating the effects of land-use change on atmospheric deposition and nutrient cycling via throughfall (the precipitation that passes through the canopy of trees) in the Amazon basin. Results from this work will increase our understanding of the chemistry of this tropical rainforest, which is one of the least understood biomes of the world. This research is critical to show how habitat destruction changes ecosystem function in the Amazon.Scientists at CENA and the University of Washington are working on complementary research, on the biogeochemical dynamics in rivers and catchments. Numerous collaborations will be forged, in addition to the one with Dr. Martinelli.***

9901158威廉姆斯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。该计划的奖项提供了机会，联合研究，并使用独特的或互补的设施，专业知识和国外的实验条件。威廉姆斯与12个月的支持工作与博士路易斯安东尼奥马蒂内利在圣保罗，中央大学，在巴西。 该项目由美国提供支持-巴西方案：威廉姆斯博士将调查土地使用变化对亚马逊盆地大气沉积和通过穿透雨（穿过树冠的降水）进行的养分循环的影响。 这项工作的结果将增加我们对热带雨林化学的理解，这是世界上最不了解的生物群落之一。这项研究对于显示栖息地破坏如何改变亚马逊的生态系统功能至关重要。CENA和华盛顿大学的科学家正在进行补充研究，研究河流和集水区的生物地球化学动力学。 除了与Martinelli博士的合作之外，还将建立许多合作关系。
