Description:
We are investigating factors governing the biological organization of Great Lakes coastal wetlands. Food web analyses using stable isotope techniques verify the role of algae as an energetic foundation, and also suggest that fundamental changes occur as a result of anthropogenic disturbance . . .I will present analyses of coastal wetlands with a range of nutrient concentrations and with hydrologic characteristics that grade from lacustrine to riverine, and will contrast the relative structure.
