BE/CBC: Biocomplexity in the Pacific Northwest: Salmon, Climate, and Hydrologic Variability

环境中的生物复杂性（BE）：耦合生物地球化学循环（CBC）项目将调查大规模气候强迫因素之间的复杂关系，整个地区的局部气候变化，欧洲文化影响前后的鲑鱼种群动态，以及植被和湖泊生态系统对这些变化的反应。Abbott博士及其同事布拉德利和弗朗西斯（均来自马萨诸塞州阿默斯特）和芬尼（阿拉斯加州）将分析该地区的高分辨率沉积物记录，以提供大时空尺度的详细记录。研究的两个重点是在太平洋西北部的湖泊中产生过去12，000年来湿度和温度变化的多代理记录，并在其中一个地点重建鲑鱼丰度。该项目将产生太平洋西北部近十年至百年尺度的气候历史，并促进对其地球化学循环的理解。该项目将侧重于鲑鱼种群和湖泊生态系统对气候变化的反应。这项研究的更广泛的影响将是在太平洋西北部的鲑鱼管理和恢复领域。

The Biocomplexity in the Environment (BE): Coupled Biogeochemical Cycles (CBC) project will investigate the complex relationships between large-scale climatic forcing factors, local climatic changes across the region, salmon population dynamics both before and after European cultural impacts, and vegetation and lake-ecosystem responses to these changes. Dr. Abbott, and colleagues, Bradley and Francis (both from U Mass, Amherst), and Finney (U Alaska), will analyze high-resolution sediment records from the region to provide detailed records over large temporal and spatial scales. The two thrusts of the research are to produce multi-proxy records of moisture and temperature variations during the last 12,000 years from lakes in the Pacific Northwest and reconstruct salmon abundance at one of these sites. The project will produce a sub-decadal to century-scale climate history of the Pacific Northwest, and advance understanding of its biogeochemical cycles. The project will focus on the response of salmon populations and lake-ecosystems to climate change. The broader impact of this research would be in the area of salmon management and restoration in the Pacific Northwest.
