U.S.-Mexico Cooperative Research: Current and Future Patterns of Vegetation and Ecosystem Function in the Regions of San Diego and La Paz, Mexico

0072140 oeschel美国墨西哥奖将支持博士之间的研究合作。圣地亚哥州立大学的Walter Oeschel， Douglas Deutschman和Paul Ganster，以及墨西哥下加利福尼亚州拉巴斯市东北生物研究中心（CIBNOR）的Arturo Muhlia Melo博士和他的团队。这项研究的总目标是发展预测拉巴斯和圣地亚哥地区干旱和半干旱生态系统中目前和未来植被和生态系统功能模式的能力。具体目标包括确定南加州和下加利福尼亚州生态系统二氧化碳通量和水利用的年际和年内格局，利用生态系统景观模型预测该区域当前和未来的碳和水通量，并通过实地取样和飞机测量区域气体和水通量以及遥感对其进行验证。半干旱生态系统往往是生物多样性、稀有和濒危物种的中心，对全球变化的影响特别敏感。拟议的合作将整合边界两侧的现有活动，以SDSU和CIBNOR的互补专业知识为基础，并将科学研究成果与社会经济背景、地方、国家和国际政策联系起来。

0072140OeschelThis U.S. Mexico award will support a research collaboration between Drs. Walter Oeschel, Douglas Deutschman, and Paul Ganster of San Diego State University and Dr. Arturo Muhlia Melo and his group at the Centro de Investigaciones Biologicas del Noroeste (CIBNOR) in La Paz, Baja California, Mexico. The overall objective of the research is to develop the capability to predict current and future patterns of vegetation and ecosystem function in the arid and semi-arid ecosystems of the La Paz and San Diego regions. Specific objectives include determining the inter- and intra annual pattern of ecosystem carbon dioxide flux and water use in Southern California and Baja California, using ecosystem landscape models to predict current and future carbon and water flux of the region and validating them with field sampling and aircraft measurement of regional gas and water fluxes and remote sensing. Semi-arid ecosystems are often centers of bio-diversity, of rare and endangered species, and are particularly sensitive to the impacts of global change. The proposed collaboration will integrate current activities on each side of the border, building on the complementary expertise at SDSU and CIBNOR, and linking results of scientific research to the socio-economic context, local, national, and international policy.
