项目摘要
Linking Belowground Phenology and Ecosystem Function in a Warming Arctic ? Non-technical abstract (E. Post, PI)This project comprises a four-year, passive warming experiment of low-Arctic tundra vegetation at a long-term study site in Greenland, with the primary aim of measuring the response of plant roots to warming, and the role of this response in ecosystem carbon exchange. Phenology, the annual timing and progression of events such as aboveground plant growth, is a well-studied an important component of the ecology of climate change, but remains under-studied belowground. This study will estimate and compare above- and belowground responses of plant phenology to warming and their respective contributions to ecosystem function, specifically the exchange of carbon between the atmosphere and tundra. It will furthermore determine which plant types, e.g., shrubs or grasses, show the greater belowground response to warming and contribution to ecosystem carbon exchange. Novel insights into the expected response of the Arctic to climate change will emerge from this experiment, which will also expand the infrastructure for field-based experimental and observational research in the Arctic. This research will promote the involvement of under-represented groups by recruitment of students through Penn State?s Minority Undergraduate Research Experience program, and promote education and dissemination of its results through a summer field ecology module at the study site and in courses at Penn State and the University of Alaska-Anchorage. Results will also be published in peer-reviewed journals and presented at international conferences by participating students and the Principal Investigators.
北极变暖时地下物候与生态系统功能的联系?非技术性摘要(E。该项目包括在格陵兰岛的一个长期研究地点对低北极苔原植被进行为期四年的被动变暖实验,主要目的是测量植物根系对变暖的反应,以及这种反应在生态系统碳交换中的作用。 物候学是一年一次的时间和事件的进展,如地上植物生长,是气候变化生态学的一个重要组成部分,但地下研究仍然不足。 这项研究将估计和比较植物物候对变暖的地上和地下反应及其各自对生态系统功能的贡献,特别是大气和苔原之间的碳交换。 它还将确定哪些植物类型,例如,灌木或草,表现出更大的地下对变暖的反应和对生态系统碳交换的贡献。 这项实验将使人们对北极对气候变化的预期反应有新的认识,还将扩大北极实地实验和观测研究的基础设施。 这项研究将促进参与代表性不足的群体通过招聘学生通过宾夕法尼亚州立大学?的少数民族本科生研究经验计划,并促进教育和传播其结果,通过夏季野外生态模块在研究地点和在宾夕法尼亚州立大学和阿拉斯加大学安克雷奇的课程。 研究结果还将发表在同行评审的期刊上,并由参与的学生和主要研究者在国际会议上发表。
