Topsoil depth substantially influences the responses to drought of the foliar metabolomes of Mediterranean forests / Rivas-Ubach, Albert (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Barbeta i Margarit, Adrià (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Guenther, Alex (University of California. Department of Earth System Science) ; Ogaya Inurrigarro, Romà (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Oravec, Michal (Akademie věd České Republiky. Centrum výzkumu globální změny) ; Urban, Otmar (Akademie věd České Republiky. Centrum výzkumu globální změny) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The upper soil provides support, water, and nutrients to terrestrial plants and is therefore crucial for forest dynamics. We hypothesised that a tree's metabolic activity (and therefore its metabolome; the total set of metabolites) would be affected by both the depth of upper soil layers and water availability. [...]

Isotope-Ratio Infrared Spectroscopy : a reliable tool for the investigation of plant-water sources? / Martín-Gómez, Paula (Universitat de Lleida) ; Barbeta i Margarit, Adrià (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Voltes, Jordi (Universitat de Lleida) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Dennis, Kate (Picarro, Inc.) ; Palacio Blasco, Sara (Instituto Pirenaico de Ecología) ; Dawson, Todd E. (University of California) ; Ferrio, Juan Pedro (Universitat de Lleida)
Stable isotopes are extensively used as tracers for the study of plant-water sources. Isotope-ratio infrared spectroscopy (IRIS) offers a cheaper alternative to isotope-ratio mass spectroscopy (IRMS), but its use in studying plant and soil water is limited by the spectral interference caused by organic contaminants. [...]

Balance between carbon gain and loss under long-term drought: impacts on foliar respiration and photosynthesis in Quercus ilex L / Sperlich, Dominik (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Barbeta i Margarit, Adrià (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Terrestrial carbon exchange is a key process of the global carbon cycle consisting of a delicate balance between photosynthetic carbon uptake and respiratory release. We have, however, a limited understanding how long-term decreases in precipitation induced by climate change affect the boundaries and mechanisms of photosynthesis and respiration. [...]

Contrasting impacts of continuous moderate drought and episodic severe droughts on the aboveground-biomass increment and litterfall of three coexisting Mediterranean woody species / Liu, Daijun (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Barbeta i Margarit, Adrià (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Yang, Xiaohong (Chongqing da xue. Key Laboratory of Horticulture Science for SouthernMountainous Regions) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Climate change is predicted to increase the aridity in the Mediterranean Basin and severely affect forest productivity and composition. The responses of forests to different timescales of drought, however, are still poorly understood because extreme and persistent moderate droughts can produce nonlinear responses in plants. [...]

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Context : In the framework of climate change, decreased tree growth and enhanced mortality induced by hot and dry conditions are increasing in many forests around the world, and particularly in Mediterranean forests. [...]

The combined effects of a long-term experimental drought and an extreme drought on the use of plant-water sources in a Mediterranean forest / Barbeta i Margarit, Adrià (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Mejía Chang, Monica (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Voltas, Jordi (Universitat de Lleida. Departament de Producció Vegetal i Ciència Forestal) ; Dawson, Todd E. (University of California, Berkeley. Department of Integrative Biology) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Vegetation in water-limited ecosystems relies strongly on access to deep water reserves to withstand dry periods. Most of these ecosystems have shallow soils over deep groundwater reserves. Understanding the functioning and functional plasticity of species-specific root systems and the patterns of or differences in the use of water sources under more frequent or intense droughts is therefore necessary to properly predict the responses of seasonally dry ecosystems to future climate.
