Graphical depiction of three sources of variation in methylmercury

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. Rails that consume more prey at higher trophic levels in the food

Biplot of principal component analysis

Biplot of principal component analysis of soil elemental composition data. Background and enriched samples are denoted. Colored points are from potentially enriched soils at mine sites, and black points are from unmined background sites. The effect of different elements on the analysis is shown by the rays, which are labeled to identify the elements.
