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.

0128178Paytan 该美国-墨西哥奖项将支持斯坦福大学的 Adina Paytan 博士与墨西哥尤卡坦半岛 Cinvestav-Merida 的 Jorge A. Herrera-Silveira 博士进行研究合作。 研究人员打算进行一项多年研究，以更好地了解红树林生态系统中甲烷产生和氧化的机制。 他们的目标是获得从红树林生态系统到大气的甲烷通量的可靠估计，并预测气候和人为变化可能导致的甲烷通量波动。 美国国家科学基金会国际科学与工程办公室和环境生物学部将为这项研究提供资金。这项研究将在墨西哥尤卡坦半岛的几个以红树林植被为主的泻湖中进行。这些泻湖具有相似的植被和气候模式，但淡水和养分输入以及人为影响水平却截然不同，因此可以对研究中的各种参数进行比较。项目结果将有助于更好地估计全球红树林生态系统对全球甲烷预算的贡献，并预测这一通量的潜在变化。合作者将为该项目带来互补的技能，其中 Herrera-Silveira 博士强调生物学方面，Paytan 博士则专注于生态系统中的生物地球化学相互作用。
