Graphical depiction of a seasonal wetland engineered to have a deeper pool and more open water on the downstream side of the wetland. This management strategy was tested during a 3-year period to determine if it resulted in a reduction of methylmercury in caged fish and surface water.

Map of the study region showing the location of lakes in (A) Florida and (B) Ohio. In total, 135 lakes in Florida and 21 lakes in Ohio, were resolvable with the full resolution MERIS data and are used in this study. Land and lakes are shown in gray and blue colors respectively.

Graphical depiction of three sources of variation that can affect accumulation of methylmercury in black rails: habitat (sediment) biogeochemistry, food web structure and biomagnification, and diet composition. Methylmercury moves from the sediment into the wetland food web and accumulates in rail tissues.
