Journal ArticleDOI
Nitrogen deposition threatens species richness of grasslands across Europe
Carly J. Stevens,Cecilia Dupré,Edu Dorland,Cassandre Gaudnik,David J. G. Gowing,Albert Bleeker,Martin Diekmann,Didier Alard,Roland Bobbink,David Fowler,Emmanuel Corcket,J. Owen Mountford,Vigdis Vandvik,Per Arild Aarrestad,Serge Muller,Nancy B. Dise +15 more
TL;DR: The results of this survey suggest that the impacts of nitrogen deposition can be observed over a large geographical range, suggesting that to protect the most sensitive grasslands resources should be focussed where deposition is currently low.
Journal ArticleDOI
Differential Effects of Oxidised and Reduced Nitrogen on Vegetation and Soil Chemistry of Species-Rich Acidic Grasslands
Edu Dorland,Carly J. Stevens,Cassandre Gaudnik,Emmanuel Corcket,Suzanne Rotthier,Katherine Wotherspoon,Mari Jokerud,Vigdis Vandvik,Merel B. Soons,Mariet M. Hefting,Per Arild Aarrestad,Didier Alard,Martin Diekmann,Cecilia Dupré,Nancy B. Dise,David J. G. Gowing,Roland Bobbink +16 more
TL;DR: In this paper, the effects of N additions on plant biomass, plant nutritional status, soil pH and soil nutrient availability were investigated in species-rich, acidic grasslands spanning a climatic gradient in the Atlantic biogeographic region of Europe in Norway, Wales and France.
Journal ArticleDOI
Soil phosphorus constrains biodiversity across European grasslands
Tobias Ceulemans,Carly J. Stevens,Luc Duchateau,Hans Jacquemyn,David J. G. Gowing,Roel Merckx,Hilary Wallace,Nils van Rooijen,Thomas van Goethem,Roland Bobbink,Edu Dorland,Cassandre Gaudnik,Didier Alard,Emmanuel Corcket,Serge Muller,Nancy B. Dise,Cecilia Dupré,Martin Diekmann,Olivier Honnay +18 more
TL;DR: It is demonstrated that, independent of the level of atmospheric nitrogen deposition and soil acidity, plant species richness was consistently negatively related to soil phosphorus, and thresholds in soil phosphorus above which biodiversity appears to remain at a constant low level are identified.
Journal ArticleDOI
The impact of nitrogen deposition on acid grasslands in the Atlantic region of Europe
Carly J. Stevens,Cecilia Dupré,Edu Dorland,Cassandre Gaudnik,David J. G. Gowing,Albert Bleeker,Martin Diekmann,Didier Alard,Roland Bobbink,David Fowler,Emmanuel Corcket,J. Owen Mountford,Vigdis Vandvik,Per Arild Aarrestad,Serge Muller,Nancy B. Dise +15 more
TL;DR: A survey of 153 acid grasslands from the Atlantic biogeographic region of Europe indicates that chronic nitrogen deposition is changing plant species composition and soil and plant-tissue chemistry.
Journal ArticleDOI
Changes in species composition of European acid grasslands observed along a gradient of nitrogen deposition
Carly J. Stevens,Carly J. Stevens,Cecilia Dupré,Cassandre Gaudnik,Edu Dorland,Nancy B. Dise,David J. G. Gowing,Albert Bleeker,Didier Alard,Roland Bobbink,David Fowler,Vigdis Vandvik,Emmanuel Corcket,J. Owen Mountford,Per Arild Aarrestad,Serge Muller,Martin Diekmann +16 more
TL;DR: In this article, the authors assessed plant and bryophyte species composition, soil chemistry (pH, base cations, metal, nitrate and ammonium concentrations, total carbon and nitrogen, and Olsen plant-available phosphorus), climatic variables, N deposition and S deposition.
