0128178PaytanThis U.S.-Mexico award will support Dr. Adina Paytan of Stanford University in a research collaboration with Dr. Jorge A. Herrera-Silveira of Cinvestav-Merida in Yucatan, Mexico. The researchers intend to work on a multiple-year study to gain a better understanding of the mechanisms underlying methane production and oxidation in mangrove ecosystems. They aim to obtain reliable estimates of methane flux from mangrove ecosystems to the atmosphere, and predict fluctuations in this flux that may result from climatic and anthropogenic change. The Office of International Science and Engineering and the Division of Environmental Biology of NSF will contribute funds for the research.The study will take place in several lagoons dominated by mangrove vegetation located on the Yucatan Peninsula in Mexico. These lagoons have similar vegetation and climate patterns yet very different levels of freshwater and nutrient inputs and anthropogenic impact, allowing for comparison of various parameters in the study. Project results will allow better estimates to be made of the contribution of worldwide mangrove ecosystems to the global methane budget and predict potential changes in this flux. The collaborators will bring complementary skills to the project with Dr. Herrera-Silveira emphasizing biological aspects and Dr. Paytan focusing on biogeochemical interactions in the ecosystem.

0128178PAYTANTHIS US-MEXICO奖将支持斯坦福大学的Adina Paytan博士，并与墨西哥尤卡坦的Cinvestav-Merida的Jorge A. Herrera-Silveira博士进行研究。 研究人员打算进行一项为期多年的研究，以更好地了解红树林生态系统中甲烷生产和氧化的机制。 他们的目的是获得从红树林生态系统到大气的可靠估计，并预测由于气候和人为变化而导致的这种通量波动。 国际科学与工程办公室以及NSF的环境生物学系将为这项研究提供资金。该研究将在墨西哥尤卡坦半岛的红树林植被主导的几个泻湖中进行。这些泻湖具有相似的植被和气候模式，但淡水和养分投入和人为影响的水平非常不同，可以比较研究中的各种参数。项目结果将允许对全球红树林生态系统对全球甲烷预算的贡献进行更好的估计，并预测这种通量的潜在变化。合作者将与Herrera-Silveira博士一起为项目带来补充技能，强调生物学方面，Paytan博士专注于生态系统中的生物地球化学互动。
