Ecosystem Evaluation

Program Overview

Research to assess the health and function of natural ecosystems, human impacts, and remediation strategies.

Recent Research

  • Major shifts in Great Lakes algae populations were observed following the invasion of quagga mussels and warming temperatures. Research on the impact of the changes in abundance and species composition will continue to understand impacts further up the food web.
  • Waterless boat cleaning stations were tested to understand how to most effectively use the tools to optimize cleaning techniques on boat interiors where aquatic invasive species may be hiding and can be moved from lake to lake.
  • Next Gen monitoring with environmental DNA (eDNA) sampling techniques has been applied to water research protocols to increase early detection of newly invading species.
