This research will analyze the pollen from selected peat cores from the tundra of Beringia, the ancient subcontinent which now includes Alaska and Northeastern Siberia. The arctic tundra is a major ecosystem which plays a significant role as a major repository of the world's carbon. Whether northern peat is still accumulating soil carbon or may actually be losing carbon is a question with important consequences for global change scenarios. This work will use plant eaology and soil studies to interpret pollen records. Pollen analysis offers ecologists a long-term perspective on vegetation change in this complex environment. Interactive activities include: teaching a course directly related to this research and introducing students to the tools and methods used to understand past environmental change. In addition, a seminar will be offered entitled Women in Prehistoric Society. This course is an exploration of the traditional biases toward gender roles in prehistory, which will enable Dr. Eisner to extend her visibility and contribution to other departments at the University of Alaska Anchorage.

这项研究将分析来自白令吉亚苔原的泥炭核心的花粉，白令吉亚是古代次大陆，现在包括阿拉斯加和西伯利亚东北部。 北极苔原是一个重要的生态系统，作为世界碳的主要储存库，发挥着重要作用。 北方泥炭是否仍在积累土壤碳或实际上可能正在失去碳，这是一个对全球变化情景具有重要影响的问题。 这项工作将使用植物气象学和土壤研究来解释花粉记录。 花粉分析为生态学家提供了一个在这种复杂环境中观察植被变化的长期视角。 互动活动包括：教授与本研究直接相关的课程，并向学生介绍用于了解过去环境变化的工具和方法。 此外，还将举办一次题为“史前社会中的妇女”的研讨会。 本课程是对史前性别角色的传统偏见的探索，这将使Dr.Reynner能够将她的知名度和贡献扩展到阿拉斯加安克雷奇大学的其他部门。
