Michael G. Ryan, 教授, 美国科罗拉多州立大学(Colorado State University)自然资源生态实验室主任、资深科学家。Michael G. Ryan教授长期从事森林生态系统研究，主要包括（1）树木生理和生态系统过程随树龄的变化；（2）碳分配和气候变化对碳分配及生产力的影响；（3）树木死亡机理；（4）植物呼吸以及植物呼吸和生产力之间的关联；（5）生态系统呼吸、土壤碳氮交互作用、土壤碳分解；（6）干扰对景观碳循环的影响；（7）树木生理，包括营养物质吸收、水分流失和碳增益的协调。Michael G. Ryan教授最近几年获得超过220万美元的研究经费，研究成果发表在Nature, PNAS, Global Change Biology, New Phytologist, Tree Physiology, Agricultural and Forest Meteorology等高水平学术刊物上。本次报告重点介绍什么因素控制生态系统代谢作用，即森林与大气之间的碳、水交换，欢迎广大师生参与讲座和讨论。
