Journal ArticleDOI
Do tree species influence soil carbon stocks in temperate and boreal forests
TL;DR: In this article, the authors reviewed and synthesized current knowledge of tree species effects on soil organic carbon (SOC) stocks in temperate and boreal forests based on common garden, retrospective paired stand and retrospective single-tree studies.
Journal ArticleDOI
Sustainable utilisation of forest biomass for energy - possibilities and problems: policy, legislation, certification, and recommendations and guidelines in the Nordic, Baltic, and other European countries.

TL;DR: In this article, the authors reviewed the contents of recommendations, guidelines, and other synthesis publications on sustainable use of forest biomass for energy and identified the extent to which wood for energy is included in forest legislation and forest certification standards under the Programme for the Endorsement of Forest Certification (PEFC) and the FSC schemes.
Journal ArticleDOI
Detection of temporal trends in atmospheric deposition of inorganic nitrogen and sulphate to forests in Europe
Peter Waldner,Aldo Marchetto,Anne Thimonier,Maria Schmitt,Michela Rogora,Oliver Granke,Volker Mues,Karin Hansen,Gunilla Pihl Karlsson,Daniel Žlindra,Nicholas Clarke,Arne Verstraeten,Andis Lazdins,Claus Schimming,Carmen Iacoban,Antti-Jussi Lindroos,Elena Vanguelova,Sue Benham,Henning Meesenburg,Manuel Nicolas,Anna Kowalska,Vladislav Apuhtin,Ülle Napa,Zora Lachmanová,Ferdinand Kristoefel,Albert Bleeker,Morten Ingerslev,Lars Vesterdal,Juan Molina,Uwe Fischer,Walter Seidling,Mathieu Jonard,Philip O'Dea,James Johnson,Richard Fischer,Martin Lorenz +35 more
TL;DR: In this article, the authors compared linear regression and Mann-Kendall trend analysis techniques often used to detect temporal trends in atmospheric deposition and found that the choice of method influenced the number of significant trends, and the slope of a trend needed to exceed a certain minimum in order to be detected despite the short-term variability of deposition.
Journal ArticleDOI
Influence of different tree-harvesting intensities on forest soil carbon stocks in boreal and northern temperate forest ecosystems
Nicholas Clarke,Per Gundersen,Ulrika Jönsson-Belyazid,O. Janne Kjønaas,Tryggve Persson,Bjarni D. Sigurdsson,Inge Stupak,Lars Vesterdal +7 more
TL;DR: In this paper, the authors reviewed the findings in the scientific literature concerning the effects of harvesting of different intensities on soil organic carbon (SOC) stocks and fluxes in boreal and northern temperate forest ecosystems to evaluate the evidence for significant SOC losses following biomass removal.
Journal ArticleDOI

TL;DR: In this article, a database of dissolved organic carbon (DOC) in soil solution was compiled and analyzed with the aim of quantifying the differences in DOC concentrations among terrestrial ecosystems, climate zones, soil, and vegetation types at global scale and identifying potential determinants of the site-to-site variability of DOC concentration in soil solutions.
