Terrestrial Run-off Increases Methylmercury Accumulation in Aquatic Ecosystems (10 of 12)

Caption

Conceptual illustration of carbon incorporation and transfer between trophic levels for a phytoplankton (NPlow, NPhigh) and bacteria (TM) based pelagic food web illustrating an increased number of trophic levels as a potential cause of enhanced MeHg bioaccumulation in a bacteria based food web.. This material relates to a paper that appeared in the Jan. 27, 2017, issue of Science Advances, published by AAAS. The paper, by S. Jonsson at Umeå University inUmeå, Sweden, and colleagues was titled, 'Terrestrial discharges mediate trophic shifts and enhance methylmercury accumulation in estuarine biota.'
