Claus Beier,Carl Beierkuhnlein,Thomas Wohlgemuth,Josep Peñuelas,Bridget A. Emmett,Christian Körner,Hans J. De Boeck,Jens Hesselbjerg Christensen,Sebastian Leuzinger,Ivan A. Janssens,Karin Hansen +10 more
TL;DR: A systematic and holistic approach to investigate how soil and plant community characteristics change with altered precipitation regimes and the consequent effects on ecosystem processes and functioning within these experiments will greatly increase their value to the climate change and ecosystem research communities.

TL;DR: In this article, the nutritional status of the main European tree species, to identify growth-limiting nutrients and to assess changes in tree nutrition during the past two decades was analyzed.

TL;DR: It is concluded that environmental and host factors explain most of the variation in ectomycorrhizal diversity, that the environmental thresholds used as major ecosystem assessment tools need adjustment and that the importance of belowground specificity and plasticity has previously been underappreciated.

Journal ArticleDOI
Tree species is the major factor explaining C:N ratios in European forest soils
TL;DR: In this article, a boosted regression tree analysis (BRT) was used to quantify forest floor, mineral and peat soil C:N ratios across European forests, and the main factors explaining these ratios were determined using fifteen site and environmental variables.
