Abstract Increasing atmospheric CO 2 enhances plant biomass production and may thereby change nutrient concentrations in tissues. The objective of this study was to identify the effect elevated on grassland that have been grown for 16 years (1998–2013). at extensively managed Giessen FACE experiment, fumigated with ambient (aCO ; eCO +20%) harvested twice annually. Concentrations C, N, P, K, Ca...

Satellite-based light use efficiency (LUE) models are important tools for estimating regional and global vegetation gross primary productivity (GPP). However, all LUE assume a constant value of maximum at canopy scale (LUEmaxcanopy) over given type. This assumption is not supported by observed plant traits regulating LUEmaxcanopy, which varies greatly even within the same ecosystem In this stud...
