Objective:
The objective of this research project is to characterize how lake biological and spatial features influence the concentration of mercury in fish.
Approach:
This is a comparative lake survey. With collaborators, the investigatorI will examine the relationship between 26 lake traits and mercury concentrations in yellow perch for 46 northern Wisconsin lakes. Potential predictors included chemical traits such as pH and water color; biological traits such as fish trophic position and body condition; and landscape traits, such as lake hydrological position and surrounding wetland abundance.
