      abstract     = {Sun-induced fluorescence (SIF) in the far-red region
                      provides a new noninvasive measurement approach that has the
                      potential to quantify dynamic changes in light-use
                      efficiency and gross primary production (GPP). However, the
                      mechanistic link between GPP and SIF is not completely
                      understood.We analyzed the structural and functional factors
                      controlling the emission of SIF at 760 nm (F760) in a
                      Mediterranean grassland manipulated with nutrient addition
                      of nitrogen (N), phosphorous (P) or nitrogen–phosphorous
                      (NP). Using the soil–canopy observation of photosynthesis
                      and energy (SCOPE) model, we investigated how
                      nutrient-induced changes in canopy structure (i.e. changes
                      in plant forms abundance that influence leaf inclination
                      distribution function, LIDF) and functional traits (e.g. N
                      content in dry mass of leaves, $N\%,$ Chlorophyll a+b
                      concentration (Cab) and maximum carboxylation capacity
                      (Vcmax)) affected the observed linear relationship between
                      F760 and GPP.We conclude that the addition of nutrients
                      imposed a change in the abundance of different plant forms
                      and biochemistry of the canopy that controls F760. Changes
                      in canopy structure mainly control the GPP–F760
                      relationship, with a secondary effect of Cab and Vcmax.In
                      order to exploit F760 data to model GPP at the
                      global/regional scale, canopy structural variability,
                      biodiversity and functional traits are important factors
                      that have to be considered.},
