*</sup>Rasmus Sørensen is a PhD student at the Department of Aquatic Sciences and Assessment at SLU, Uppsala, Sweden. His studies are focused on mercury leakage from managed forestland, involving studies of forest hydrology. His address: Department of Aquatic Science and Assessment, P.O. Box 7050, SE-750 07 Uppsala, Sweden. rasmus.sorensen@vatten.slu.se
^**Eva Ring has a PhD in soil science and works at Skogforsk—The Forestry Research Institute of Sweden. Her research focuses on the environmental effects of forestry on water chemistry. Her address: Skogforsk Uppsala Science Park, SE-751 83 Uppsala, Sweden. eva.ring@skogforsk.se
^***Markus Meili is an associate professor in biogeochemistry at the Department of Applied Environmental Science (ITM), Stockholm University. He has a particular interest in the coupled cycling of contaminants and nutrients in aquatic ecosystems. His address: Department of Applied Environmental Science (ITM), Stockholm University, SE-106 91 Stockholm, Sweden. markus.meili@itm.su.se
^****Lars Högbom is an associate professor in soil science and works at Skogforsk—The Forestry Research Institute of Sweden. His research focuses on the environmental effects of forestry, mainly with respect to nitrogen. His address: Skogforsk Uppsala Science Park, SE-751 83 Uppsala, Sweden. lars.hogbom@skogforsk.se
^*****Jan Seibert is a professor at the University of Zurich, where he is heading the group on hydrology and climate. His main research interest is hydrological modeling at different scales in combination with experimental studies. He is also affiliated with Stockholm University. His address: Department of Geography, University of Zurich, Winterthurerstrasse 190, CH-8057 Zürich, Switzerland. jan.seibert@geo.uzh.ch
^******Thomas Grabs is a PhD student at the Department of Physical Geography and Quaternary Geology at Stockholm University, Sweden. His is studying stream water quality with a main focus on dissolved organic carbon at the landscape scale. His address: Department of Physical Geography and Quaternary Geology, Stockholm University, SE-106 91 Stockholm, Sweden. thomas.grabs@natgeo.su.se
^*******Hjalmar Laudon is professor and chair of forest landscape biogeochemistry at SLU in Umeå. His research mainly concern understanding natural variability and human perturbation of hydrological and biogeochemical patterns in the boreal landscape. His address: Forest Ecology and Management, SLU, SE-901 86 Umeå, Sweden. hjalmar.laudon@seksko.slu.se
^********Kevin Bishop is professor of environmental assessment. Research to distinguish human influence from natural variability in the surface waters of forested landscapes has led him to consider how silviculture influences mercury cycling.
