Journal ArticleDOI
Dissolved organic carbon trends resulting from changes in atmospheric deposition chemistry.
Don Monteith,John L. Stoddard,Chris D. Evans,Heleen A. de Wit,Martin Forsius,Tore Høgåsen,Anders Wilander,Brit Lisa Skjelkvåle,Dean S. Jeffries,Jussi Vuorenmaa,Bill Keller,Jiri Kopacek,Josef Vesely +12 more
TL;DR: It is shown that rising trends in DOC between 1990 and 2004 can be concisely explained by a simple model based solely on changes in deposition chemistry and catchment acid-sensitivity, and that the rise in DOC is integral to recovery from acidification.
Journal ArticleDOI
Regional trends in aquatic recovery from acidification in North America and Europe
John L. Stoddard,Dean S. Jeffries,A. Lükewille,Thomas A. Clair,Peter J. Dillon,Charles T. Driscoll,Martin Forsius,M. Johannessen,Jeffrey S. Kahl,James H. Kellogg,A. Kemp,Jaakko Mannio,Don Monteith,Peter S. Murdoch,S. Patrick,A. Rebsdorf,Brit Lisa Skjelkvåle,M. P. Stainton,T. Traaen,H. van Dam,Katherine E. Webster,J. Wieting,A. Wilander +22 more
TL;DR: This article analyzed regional trends between 1980 and 1995 in indicators of acidification (sulphate, nitrate and base-cation concentrations, and measured (Gran) alkalinity) for 205 lakes and streams in eight regions of North America and Europe.
Journal ArticleDOI
Regional scale evidence for improvements in surface water chemistry 1990–2001
Brit Lisa Skjelkvåle,John L. Stoddard,Dean S. Jeffries,Kjetil Tørseth,Tore Høgåsen,J. Bowman,Jaakko Mannio,Don Monteith,Rosario Mosello,Michela Rogora,Dorota Rzychoń,J. Vesely,J. Wieting,Anders Wilander,Adam Worsztynowicz +14 more
TL;DR: Results from the ICP Waters programme clearly show widespread improvement in surface water acid-base chemistry, in response to emissions controls programs and decreasing acidic deposition, which may lead to biological recovery in the future.
Journal ArticleDOI
Regulation of Nitrate‐N Release from Temperate Forests: A Test of the N Flushing Hypothesis
Irena F. Creed,Lawrence E. Band,Neil W. Foster,Ian K. Morrison,J. A. Nicolson,R. S. Semkin,Dean S. Jeffries +6 more
TL;DR: In this article, Hornberger et al. used the Regional Hydro-Ecological Simulation System to simulate water, carbon, and N dynamics and found that significant spatial and temporal variability in the release of nitrate-nitrogen from catchments in a sugar maple forest in central Ontario was observed.
Journal ArticleDOI
The Widespread Threat of Calcium Decline in Fresh Waters
Adam Jeziorski,Norman D. Yan,Norman D. Yan,Andrew M. Paterson,Anna M. DeSellas,Anna M. DeSellas,Michael A. Turner,Dean S. Jeffries,Bill Keller,Russ C. Weeber,Don K. McNicol,Michelle E. Palmer,Kyle McIver,Kristina M. A. Arseneau,Brian K. Ginn,Brian F. Cumming,John P. Smol +16 more
TL;DR: By examining crustacean zooplankton remains preserved in lake sediment cores, this work document near extirpations of calcium-rich Daphnia species, which are keystone herbivores in pelagic food webs, concurrent with declining lake-water calcium.
