IPY: Establishing a Legacy for International Collaboration Investigating Ecological Consequences of Arctic Climate Change

向宾夕法尼亚州立大学提供了资金，以支持Eric Post博士在国际极地年期间在丹麦环境部居住一年。在丹麦，波斯特博士将协调他在西格陵兰岛Kangerlussuaq的生态研究与格陵兰东北部扎肯伯格的丹麦同事进行的研究。这项合作研究试图了解北极生物生态的基本方面，以及它们如何应对环境变化。PI在丹麦环境部的住所将促进正式合作、基础设施的发展和数据共享，这将促进对北极生态和气候变化可能影响的更深入了解。将特别关注北极高地和低北极地区动植物之间的相互作用的比较和对比。这笔资金还将用于正式确定在坎格卢斯苏阿克(宾夕法尼亚州)和扎肯伯格实验室(丹麦环境部)学习生态学的学生和博士后研究员的交流。这项合作工作将整合低北极地区(Kangerlussuaq)和高北极地区(Zackenberg)的研究，重点放在三个方面：(1)个体和物种一级对气候变暖的反应(如何在高北极和低北极社区中按个体的生活史事件顺序对气候变暖作出反应)；(2)社区一级对气候变暖的反应(结合对生物过程时间和时间变化的长期观察，以确定对气候变暖的反应是否根据营养水平以及北极高地和低地之间的不同而不同)；以及(3)生态系统对气候变暖的响应(调查植物-动物相互作用在低北极和高北极环境中植物对气候变暖的响应中的作用)。资金将促进对研究生和博士后研究员的国际指导，为格陵兰的长期国际科学合作建立基础设施，并提高公众对北极生态和全球变暖威胁的认识。

Funding was provided to Pennsylvania State University to support for a one-year residence for Dr. Eric Post at the Danish Ministry of Environment during the International Polar Year. In Denmark, Dr. Post will coordinate his ecological research at Kangerlussuaq, West Greenland with research conducted by Danish colleagues at Zackenberg, Northeast Greenland. This collaborative research seeks to understand fundamental aspects of the ecology of Arctic organisms and how they are responding to environmental change. The PI's residence at the Danish Ministry of Environment will promote formal collaboration, the development of infrastructure, and data-sharing that will foster deeper understanding of Arctic ecology and the likely effects of climate change. Specific focus will be given to comparisons and contrasts between the interaction between plants and animals at high- and low-Arctic sites. The funding also will be used to formalize the exchange of students and post-doctoral fellows studying ecology at Kangerlussuaq (Pennsylvania State) and at Zackenberg laboratory (Danish Ministry of Environment). The collaborative effort will integrate research from the low-Arctic site (Kangerlussuaq) and the high-Arctic site (Zackenberg) with three foci: (1) individual- and species-level responses to climatic warming (how to the sequences of life history events of individuals respond to warming in high and low-Arctic communities); (2) community-level response to climatic warming (integrating long-term observations of the timing of biological processes and changes in that timing to determine whether responses to warming differ according to trophic level and between the high- and low Arctic); and (3) ecosystem-level response to climatic warming (investigating the role of plant-animal interactions in vegetation response to climatic warming in low- and high-Arctic environments).The funding will foster international mentoring of graduate students and postdoctoral fellows; establish the infrastructure for long-term, international scientific collaboration in Greenland; and enhance public awareness of Arctic ecology and threats posed by global warming.
