Bioaccumulation of methylmercury in wood frogs and spotted salamanders in Vermont vernal pools.

Mercury (Hg) has accumulated in forested landscapes in the Northeastern U.S., and hotspots with enhanced deposition have been identified throughout the region.

Mercury bioaccumulation and trophic transfer in the terrestrial food web of a montane forest.

We investigated mercury (Hg) concentrations in a terrestrial food web in high elevation forests in Vermont. Hg concentrations increased from autotrophic organisms to herbivores < detritivores < omnivores < carnivores. Within the carnivores studied, raptors had higher blood Hg concentrations than their songbird prey.
