Habitat Supply and Trophic Transfer in Lake Superior

Researchers plan to estimate phytoplankton, zooplankton, and fish   biomass as a function of the organism's body size in three regions   of Lake Superior. They will compare predator demand and prey supply   among these areas by calculating the relative rates of energy   transfer up the food chains. Of the three locations, researchers   speculate that biological production will be greatest near the   Duluth-Superior Harbor but that the rate of energy flow will be most   efficient northeast of the Apostle Islands where there are fewer   nutrients, but also fewer invasive species and anglers. A portion of   Minnesota's North Shore will also be investigated through a   combination of fieldwork and remote sensing. Results will aid   efforts to manage Lake Superior fisheries.
