项目摘要

Two interdisciplinary workshops will focus on ecological change and human impacts during the Holocene on the Aleutian Islands. The Aleutian Islands represent a model ecosystem to track human-environment interactions over the past 10,000 years. The Aleutians contain a 9,000-year record of human occupation. For most of the Holocene, the archipelago has formed the boundary between the North Pacific Rim and Bering Sea. The region is a rich ecotone with ocean fisheries, large sea mammal populations, thick kelp forests, complex near-shore ecosystems and intertidal zones, spawning streams, and a highly diverse avian fauna. The workshops will be used to (1) identify existing oceanographic, climatological, geophysical, and biological data that document complex environmental change in the Aleutians; (2) identify research areas and investigators needed to provide additional data necessary to reconstruct environmental change in the Aleutians; and (3) correlate existing data from the physical and biological sciences with the recorded history of human occupation of, and adaptation to, the island chain; and (4) design a research strategy to provide a more precise temporal framework for Holocene environmental change and concomitant human responses. This project is an award emanating from the FY 2001 special competition in Biocomplexity in the Environment focusing on the Dynamics of Coupled Natural and Human Systems.

两个跨学科讲习班将侧重于阿留申群岛全新世期间的生态变化和人类影响。阿留申群岛是一个典型的生态系统，可以跟踪过去10，000年来人类与环境的相互作用。阿留申群岛有9,000年的人类居住记录。在全新世的大部分时间里，该群岛形成了北太平洋沿岸和白令海之间的边界。该地区是一个丰富的生态交错带，拥有海洋渔业、大量海洋哺乳动物种群、茂密的海藻森林、复杂的近岸生态系统和潮间带、产卵河流和高度多样化的鸟类。讲习班将用于：（1）确定记录阿留申群岛复杂环境变化的现有海洋学、气候学、地球物理学和生物学数据;（2）确定为重建阿留申群岛环境变化提供额外必要数据所需的研究领域和调查人员;以及（3）将来自物理和生物科学的现有数据与有记录的人类占领和适应岛链的历史相关联;（4）设计一个研究策略，为全新世环境变化和伴随的人类反应提供一个更精确的时间框架。该项目是2001财政年度环境中生物复杂性特别竞赛的一个奖项，重点是耦合自然和人类系统的动力学。
