We help ensure that Minnesota and Great Lakes aquatic resources are being used in sustainable ways, and that restoration activities truly achieve their goals. Our team specializes in research on the ecology of aquatic macroinvertebrate and fish assemblages and assessing the condition of their habitat in streams, the nearshore area of lakes, wetlands, including Great Lakes coastal wetlands. We excel at the design of experimental and monitoring studies, including designing and performing Before-After Control-Impact (BACI) studies to assess restoration and recovery efforts, identifying stressors that may be affecting aquatic resources, assessing the condition of aquatic ecosystems using fish and aquatic invertebrates, and determining the effects of aquatic invasive species on ecosystems and food webs.
Our team includes aquatic macroinvertebrate taxonomists certified by the Society for Freshwater Science and researchers with strong statistical skills. In addition, we pride ourselves on our quality control and quality assurance measures. Our clients are assured of high quality data and results. We have compiled and maintain decades worth of historic local data that allow us to put current results into historical context.
We use aquatic macroinvertebrates and fish to assess the condition of Minnesota’s and the Great Lakes aquatic ecosystems. This includes assessing how well we humans are doing at meeting sustainable use goals, improving aquatic ecosystems through restoration activities, and understanding the effects of aquatic invasive species.
