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）项目将研究大尺度气候强迫因子、整个地区的局部气候变化、欧洲文化影响前后鲑鱼种群动态以及植被和湖泊生态系统对这些变化的响应之间的复杂关系。阿博特博士和他的同事布拉德利和弗朗西斯（都来自马萨诸塞大学阿姆赫斯特分校）以及芬尼（来自阿拉斯加大学）将分析该地区的高分辨率沉积物记录，以提供大时间和空间尺度的详细记录。这项研究的两个重点是，在过去12000年里，从太平洋西北部的湖泊中获取湿度和温度变化的多代理记录，并重建其中一个地点的鲑鱼数量。该项目将生成太平洋西北地区年代际至百年尺度的气候历史，并促进对其生物地球化学循环的理解。该项目将重点关注鲑鱼种群和湖泊生态系统对气候变化的反应。这项研究将对西北太平洋地区的鲑鱼管理和恢复产生更广泛的影响。

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.
