41 p, 838.7 KB Correction of PRI for carotenoid pigment pools improves photosynthesis estimation across different irradiance and temperature conditions / Kováč, Daniel (Global Change Research Institute CAS) ; Veselá, Barbora (Czech Academy of Sciences. Global Change Research Institute) ; Klem, Karel (Czech Academy of Sciences. Global Change Research Institute) ; Večeřová, Kristýna (Global Change Research Institute CAS) ; Materová Kmeco, Zuzana (Ostrava University) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Urban, Otmar (Global Change Research Institute CAS)
We studied the influence of changing carotenoid pigments on the sensitivity of the photochemical reflectance index (PRI) to photosynthesis dynamics. The goal of the measurements was to examine how the introduction of ΔPRI into the working dataset can improve the estimation of photosynthesis. [...]

19 p, 969.2 KB Different determinants of radiation use efficiency in cold and temperate forests / Balzarolo, Manuela (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Valdameri, Nadia (University of Antwerp. Department of Biology) ; Fu, Yongshuo H.. (Sino-French Institute for Earth System Science) ; Schepers, Lennert (University of Antwerp. Department of Biology) ; Janssens, Ivan (University of Antwerp. Department of Biology) ; Campioli, Matteo (University of Antwerp. Department of Biology)
To verify which vegetation and environmental factors are the most important in determining the spatial and temporal variability of average and maximum values of radiation use efficiency (RUEann and RUEmax, respectively) of cold and temperate forests. [...]

11 p, 1.9 MB Assessing ecosystem isoprene emissions by hyperspectral remote sensing / Balzarolo, Manuela (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Filella, Iolanda (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Portillo-Estrada, Miguel (University of Antwerp. Center of Excellence PLECO) ; Ceulemans, Reinhart (University of Antwerp. Center of Excellence PLECO)
This study examined the relationship between foliar isoprene emissions, light use efficiency and photochemical reflectance index (PRI) throughout the canopy profile and explored the contribution of xanthophyll cycle pigments versus other carotenoid pigments to the isoprene/PRI relationship. [...]

27 p, 2.9 MB Potential of Photochemical reflectance index for indicating photochemistry and light use efficiency in leaves of European beech and Norway spruce trees / Kováč, Daniel (Global Change Research Institute CAS) ; Veselovská, Petra (Global Change Research Institute CAS) ; Klem, Karel (Global Change Research Institute CAS) ; Večeřová, Kristýna (Global Change Research Institute CAS) ; Ač, Alexander (Global Change Research Institute CAS) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Urban, Otmar (Global Change Research Institute CAS)
Hyperspectral reflectance is becoming more frequently used for measuring the functions and productivity of ecosystems. The purpose of this study was to re-evaluate the potential of the photochemical reflectance index (PRI) for evaluating physiological status of plants. [...]

Institute for Atmospheric and Climate Science) ; Keenan, Trevor F. (UC Berkeley. Department of Environmental Science, Policy and Management) ; Prentice, Iain Colin (Imperial College London. Department of Life Sciences) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Seneviratne, Sonia I. (ETH Zürich. Institute for Atmospheric and Climate Science)
Terrestrial primary productivity and carbon cycle impacts of droughts are commonly quantified using vapour pressure deficit (VPD) data and remotely sensed greenness, without accounting for soil moisture. [...]
