20 p, 4.2 MB Quantifying soil moisture impacts on light use efficiency across biomes / Stocker, Benjamin (Centre de Recerca Ecològica i Aplicacions Forestals) ; Zscheischler, Jakob (ETH Zurich. Institute for Atmospheric and Climate Science) ; Keenan, Trevor F. (UC Berkeley. Department of Environmental Science, Policy and Management) ; Prentice, I. Colin (Imperial College London. Department of Life Sciences) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals) ; Seneviratne, Sonia I. (ETH Zurich. 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. [...]

24 p, 13.3 MB Process based inventory of isoprenoid emissions from European forests : model comparisons, current knowledge and uncertainties / Keenan, Trevor (Centre de Recerca Ecològica i Aplicacions Forestals) ; Niinemets, Ülo (Institute of Agricultural and Environmental Sciences. Estonian University of Life Sciences) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Gracia, Carles (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Large uncertainties exist in our knowledge of regional emissions of non-methane biogenic volatile organic compounds (BVOC). We address these uncertainties through a two-pronged approach by compiling a state of the art database of the emissions potentials for 80 European forest species, and by a model assessment and inter-comparison, both at the local and regional scale, under present and projected future climatic conditions. [...]

22 p, 11.0 MB Improved understanding of drought controls on seasonal variation in Mediterranean forest canopy CO₂ and water fluxes through combined in situ measurements and ecosystem modelling / Keenan, Trevor (Centre de Recerca Ecològica i Aplicacions Forestals) ; García, R. (Laboratoire des Sciences du Climat et de l'Environment) ; Friend, A. D. (University of Cambridge. Department of Geography) ; Zaehle, S. (Laboratoire des Sciences du Climat et de l'Environment) ; Gracia, Carles (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i Aplicacions Forestals)
Water stress is a defining characteristic of Mediterranean ecosystems, and is likely to become more severe in the coming decades. Simulation models are key tools for making predictions, but our current understanding of how soil moisture controls ecosystem functioning is not sufficient to adequately constrain parameterisations. [...]

18 p, 1.2 MB Process-based simulation of seasonality and drought stress in monoterpene emission models / Grote, R. (Karlsruhe Institute of Technology. Institute for Meteorology and Climate Research) ; Keenan, Trevor (Centre de Recerca Ecològica i Aplicacions Forestals) ; Lavoir, A. V. (Centre d'Ecologie Fonctionnelle et Evolutive-CNRS. DREAM Unit) ; Staudt, M. (Centre d'Ecologie Fonctionnelle et Evolutive-CNRS. DREAM Unit)
Canopy emissions of volatile hydrocarbons such as isoprene and monoterpenes play an important role in air chemistry. They depend on various environmental conditions, are highly species-specific and are expected to be affected by global change. [...]

11 p, 390.6 KB Seasonality of monoterpene emission potentials in Quercus ilex and Pinus pinea : implications for regional VOC emissions modeling / Keenan, Trevor (Centre de Recerca Ecològica i Aplicacions Forestals) ; Niinemets, Ülo (Eesti Maaülikool. Institut of Agricultural and Environmental Sciences) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Gracia, Carles (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
VOC emissions from terrestrial ecosystems provide one of the principal controls over oxidative photochemistry in the lower atmosphere and the resulting air pollution. Such atmospheric processes have strong seasonal cycles. [...]

16 p, 472.8 KB The importance of mesophyll conductance in regulating forest ecosystem productivity during drought periods / Keenan, Trevor (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sabate i Jorba, Santi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Gracia, Carlos (Centre de Recerca Ecològica i Aplicacions Forestals)
Water availability is the most limiting factor to global plant productivity, yet photosynthetic responses to seasonal drought cycles are poorly understood, with conflicting reports on which limiting process is the most important during drought. [...]

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i Aplicacions Forestals)
Assessing the potential future of current forest stands is a key to design conservation strategies and understanding potential future impacts to ecosystem service supplies. This is particularly true in the Mediterranean basin, where important future climatic changes are expected. [...]
