Article
Goran Bostedt, Auteur ; Stefan Lofgren, Auteur ; Sophia Innala, Auteur ; Kevin Bishop, AuteurAcidification of soils and surface waters caused by acid deposition is still a major problem in southern Scandinavia, despite clear signs of recovery. Besides emission control, liming of lakes, streams, and wetlands is currently used to ameliora[...]
Article
Rasmus Sorensen, Auteur ; Markus Meili, Auteur ; Lars Lambertsson, Auteur ; Claudia von Bromssen, Auteur ; Kevin Bishop, AuteurForest harvest is hypothesized to increase the mercury (Hg) load in aquatic ecosystems. The Balsjo paired catchment study examined the outputs of methylmercury (MeHg) and total mercury (Hg(tot)) from two boreal catchments during the 2 y followin[...]

Kevin Bishop, Auteur ; Craig Allan, Auteur ; Lage Bringmark, Auteur ; Edenise Garcia, Auteur ; Sofie Hellsten, Auteur ; Lars Hogbom, Auteur ; Kjell Johansson, Auteur ; Anja Lomander, Auteur ; Markus Meili, Auteur ; John Munthe, Auteur ; Mats Nilsson, Auteur ; Petri Porvari, Auteur ; Ulf Skyllberg, Auteur ; Rasmus Sorensen, Auteur ; Therese Zetterberg, Auteur ; Staffan Akerblom, AuteurMercury (Hg) levels are alarmingly high in fish from lakes across Fennoscandia and northern North America. The few published studies on the ways in which silviculture practices influence this problem indicate that forest operations increase Hg i[...]
Article
Solomon Gebreyohannis Gebrehiwot, Auteur ; Ayele Taye, Auteur ; Kevin Bishop, AuteurThis study analyses the relation of forest cover and stream flow on the 266 km(2) Koga watershed in a headwater of Blue Nile Basin using both observed hydrological data and community perception. The watershed declined from 16% forest cover in 19[...]
Article
Rasmus Sorensen, Auteur ; Eva Ring, Auteur ; Markus Meili, Auteur ; Lars Hogbom, Auteur ; Jan Seibert, Auteur ; Thomas Grabs, Auteur ; Hjalmar Laudon, Auteur ; Kevin Bishop, AuteurTo understand how forest harvest influences the aquatic environment, it is essential to determine the changes in the flow regime. This paper presents changes in the hydrological regime during the first 2 y after harvest in two catchments of the [...]
Article
Karin Eklof, Auteur ; Rolf Lidskog, Auteur ; Kevin Bishop, AuteurInputs of anthropogenic mercury (Hg) to the environment have led to accumulation of Hg in terrestrial and aquatic ecosystems, contributing to fish Hg concentrations well above the European Union standards in large parts of Fennoscandia. Forestry[...]

Kevin Bishop, Auteur ; Keith Beven, Auteur ; Georgia Destouni, Auteur ; Katarina Abrahamsson, Auteur ; Lotta Andersson, Auteur ; Richard K. Johnson, Auteur ; Johan Rodhe, Auteur ; Niclas Hjerdt, AuteurThe goals for water-quality and ecosystem integrity are often defined relative to "natural" reference conditions in many water-management systems, including the European Union Water Framework Directive. This paper examines the difficulties creat[...]
Article
Hjalmar Laudon, Auteur ; Johannes Hedtjarn, Auteur ; Jakob Schelker, Auteur ; Kevin Bishop, Auteur ; Rasmus Sorensen, Auteur ; Anneli Agren, AuteurTo determine if forestry affects stream water dissolved organic carbon (DOC) concentrations, we conducted high frequency water sampling at a clear-cut catchment experiment in northern Sweden 1 year after harvesting. The overall finding was that [...]
Article
Mattias Winterdahl, Auteur ; Johan Temnerud, Auteur ; Martyn N. Futter, Auteur ; Stefan Lofgren, Auteur ; Filip Moldan, Auteur ; Kevin Bishop, AuteurShort-term variability in stream water dissolved organic carbon (DOC) concentrations is controlled by hydrology, climate and atmospheric deposition. Using the Riparian flow-concentration Integration Model (RIM), we evaluated factors controlling [...]

Hjalmar Laudon, Auteur ; Lenka Kuglerova, Auteur ; Ryan A. Sponseller, Auteur ; Martyn Futter, Auteur ; Annika Nordin, Auteur ; Kevin Bishop, Auteur ; Tomas Lundmark, Auteur ; Gustaf Egnell, Auteur ; Anneli M. Agren, AuteurProtecting water quality in forested regions is increasingly important as pressures from land-use, long-range transport of air pollutants, and climate change intensify. Maintaining forest industry without jeopardizing sustainability of surface w[...]
