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.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Sperlich, Dominik (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sànchez Costa, Elisenda (Centre de Recerca Ecològica i Aplicacions Forestals) ; Cotillas de la Torre, Miriam (Centre de Recerca Ecològica i Aplicacions Forestals) ; Gracia, Carles (Centre de Recerca Ecològica i Aplicacions Forestals)
Drought has been shown to reduce soil respiration (SR) in previous studies. Meanwhile, studies of the effect of forest management on SR yielded contrasting results. However, little is known about the combined effect of drought and forest management on SR. [...]

33 p, 990.2 KB Seasonal variability of foliar photosynthetic and morphological traits and drought impacts in a Mediterranean mixed forest / Sperlich, Dominik (Centre de Recerca Ecològica i Aplicacions Forestals) ; Chang, C. T. (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Gracia, Carles (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i Aplicacions Forestals)
The Mediterranean region is a hot spot of climate change vulnerable to increased droughts and heat waves. Scaling carbon fluxes from leaf to landscape levels is particularly challenging under drought 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, 721.7 KB Foliar photochemical processes and carbon metabolism under favourable and adverse winter conditions in a Mediterranean mixed forest, Catalonia (Spain) / Sperlich, Dominik (Centre de Recerca Ecològica i Aplicacions Forestals) ; Chang, C. T. (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Gracia, Carles (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i Aplicacions Forestals)
Evergreen trees in the Mediterranean region must cope with a wide range of environmental stresses from summer drought to winter cold. The mildness of Mediterranean winters can periodically lead to favourable environmental conditions above the threshold for a positive carbon balance, benefitting evergreen woody species more than deciduous ones. [...]

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. [...]

87 p, 225.7 KB Modelització de la dinàmica de combustible en ecosistemes arbustius mediterranis / Pla Ferrer, Eduard ; Gracia, Carles, dir. (Universitat de Barcelona) ; Rodà, Ferran, dir. (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Els incendis forestals han esdevingut una de les principals problemàtiques ambientals a l'àrea mediterrània. En les darreres dècades, el nombre de focs i d'àrea cremada han augmentat notablement. [...]
Wildland fires are one of the most important environmental problems in Mediterranean regions. In the last decades, the number of fires and burnt surface has increased remarkably. Phytomass successional patterns determine structural characteristics of the vegetation and, hence, fire risk. [...]
