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,

长期的观点对于区分自然生态系统变异性与人类影响的影响很有用，并认识到环境变化的速度和幅度。旧目的学是一种使用沉积物记录中保存的物理，化学和生物学信息的科学，可以在长时间（通常数十年到几千年）中跟踪环境变化。我的研究计划结合了一种古学的方法和现代的生态抽样，以更好地了解淡水生态系统如何应对自然过程和被人为引起的压力源。这种跨学科的方法可以是确定因果关系，建立基线生态系统条件并在人类活动影响下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底部藻类的滋扰增长（Blooms）的原因和影响，
