Natural abundance of 13C in CO2 respired from forest soils reveals speed of link between tree photosynthesis and root respiration.
TL;DR: Soil respiration from a boreal mixed coniferous forest showed large seasonal variation in natural abundance of 13C, and it was suggested that high δ13C values were caused by effects of air humidity on isotope fractionation during photosynthesis.
Journal ArticleDOI
Tree growth and soil acidification in response to 30 years of experimental nitrogen loading on boreal forest
TL;DR: In this article, the effects of nitrogen load on trees and soils in a uniquely long-term (30 years) experiment with annual N loading on an unpolluted boreal forest were evaluated.
Journal ArticleDOI
Nitrogen isotopes link mycorrhizal fungi and plants to nitrogen dynamics
Erik A. Hobbie,Peter Högberg +1 more
TL;DR: Climate may primarily influence δ15N patterns in soils and plants by determining the primary loss mechanisms and which types of mycorrhizal fungi and associated vegetation dominate across climatic gradients.
Journal ArticleDOI
High temporal resolution tracing of photosynthate carbon from the tree canopy to forest soil microorganisms
Peter Högberg,Mona N. Högberg,S. G. Göttlicher,Nicholas R. Betson,Sonja G. Keel,Daniel B. Metcalfe,Catherine Campbell,Andreas Schindlbacher,Vaughan Hurry,Thomas Lundmark,Sune Linder,Torgny Näsholm +11 more
TL;DR: Simultaneous labelling of the soil with (15)NH(+)(4) showed that the ectomycorrhizal roots, which were the strongest sinks for photosynthate, were also the most active sinks for soil nitrogen, highlighting the close temporal coupling between tree canopy photosynthesis and a significant fraction of soil activity in forests.
Journal ArticleDOI
Quantification of effects of season and nitrogen supply on tree below-ground carbon transfer to ectomycorrhizal fungi and other soil organisms in a boreal pine forest.

TL;DR: In this article, high-resolution tracing of 13C from canopy photosynthesis to different groups of soil organisms in a young boreal Pinus sylvestris forest was conducted.
