Paleoenvironmental investigation of an emerging stressor to Canadian salmon rivers

长远的观点有助于区分自然生态系统的可变性和人类的影响，并认识到环境变化的速度和程度。古湖沼学是一门利用沉积物记录中保存的物理、化学和生物信息来追踪长期(通常是几十年到几千年)环境变化的科学。我的研究项目结合了古湖沼学方法和现代生态采样，以更好地了解淡水生态系统如何对自然过程和人类造成的压力做出反应。这种跨学科的方法可以成为确定因果关系、建立基线生态系统条件以及在人类活动的影响之后设定现实的恢复目标的强大工具。我提出的研究计划旨在了解海底藻类滋生(水华)的原因和影响，

A long-term perspective is useful to distinguish natural ecosystem variability from human impacts, and to recognize the rates and magnitude of environmental change. Paleolimnology is the science that uses the physical, chemical, and biological information preserved in sediment records to track environmental changes over long periods of time, often decades to millennia. My research program combines a paleolimnological approach and modern ecological sampling to better understand how freshwater ecosystems respond to natural processes and human-caused stressors. This interdisciplinary approach can be a powerful tool to determine cause-and-effect, establish baseline ecosystem conditions, and set realistic recovery goals following the impacts from human activities. My proposed research program aims to understand the causes and effects of nuisance growths (blooms) of the bottom-dwelling alga,
