9 p, 3.8 MB Stem mortality and forest Dieback in a 20-years experimental Drought in a Mediterranean holm oak forest / Ogaya Inurrigarro, Romà (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Liu, Daijun (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Barbeta i Margarit, Adrià (Universitat de Barcelona. Departament de Biologia Evolutiva, Ecologia i Ciències Ambientals) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Climatic warming is predicted to increase the intensity and duration of extreme weather such as droughts and heat waves. Climate change could therefore increase stem mortality and forest dieback in many ecosystems around the world, especially in semi-arid forests. [...]

Departament de Geografia)
Remote sensing is providing an increasing number of crucial data about Earth. Systematic revisitation time allows the analysis of long time series as well as imagery utilization in the most interesting moments. [...]

The quantification of isoprene and monoterpene emissions at the ecosystem level with available models and field measurements is not entirely satisfactory. Remote-sensing techniques can extend the spatial and temporal assessment of isoprenoid fluxes. [...]

48 p, 2.1 MB Vegetation baseline phenology from kilometric global LAI satellite products / Verger Ten, Aleixandre (Centre de Recerca Ecològica i Aplicacions Forestals) ; Filella Cubells, Iolanda (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Baret, Frédéric (Environnement Méditerranéen et Modélisation des Agro-Hydrosystèmes) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Land surface phenology derived from remotely sensed satellite data can substantially improve our macroecological knowledge and the representation of phenology in earth system models. We characterized the baseline phenology of the vegetation at the global scale from the GEOCLIM climatology of leaf area index (LAI) estimated from 1-km SPOT-VEGETATION time series for 1999-2010.

16 p, 11.1 MB A data assimilation framework for constraining upscaled cropland carbon flux seasonality and biometry with MODIS / Sus, Oliver (Centre de Recerca Ecològica i Aplicacions Forestals) ; Heuer, M. W. (Air Resources Laboratory (U.S.). Atmospheric Turbulence and Diffusion Division) ; Meyers, T. P. (Air Resources Laboratory (U.S.). Atmospheric Turbulence and Diffusion Division) ; Williams, M. (University of Edinburgh. School of GeoSciences)
Agroecosystem models are strongly dependent on information on land management patterns for regional applications. Land management practices play a major role in determining global yield variability, and add an anthropogenic signal to the observed seasonality of atmospheric CO₂ concentrations. [...]

8 p, 173.7 KB Remote estimation of carbon dioxide uptake by a Mediterranean forest / Garbulsky, Martín Fabio (Centre de Recerca Ecològica i Aplicacions Forestals) ; Filella Cubells, Iolanda (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals. Unitat d'Ecofisiologia i Canvi Global) ; Papale, Dario (Universidad de Buenos Aires. Faculty of Agronomy)
The estimation of the carbon balance in ecosystems, regions, and the biosphere is currently one of the main concerns in the study of the ecology of global change. Current remote sensing methodologies for estimating gross primary productivity are not satisfactory because they rely too heavily on (i) the availability of climatic data, (ii) the definition of land-use cover, and (iii) the assumptions of the effects of these two factors on the radiation-use efficiency of vegetation (RUE).
