36 p, 2.7 MB Rhizodeposition under drought and consequences for soil communities and ecosystem resilience / Preece, Catherine (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Background: Rhizodeposition is the release of organic compounds from plant roots into soil. Positive relationships between rhizodeposition and soil microbial biomass are commonly observed. Rhizodeposition may be disrupted by increasing drought however the effects of water stress on this process are not sufficiently understood. [...]

10 p, 481.9 KB Effective use of water and increased dry matter partitioned to grain contribute to yield of common bean improved for drought resistance / Polania, Jose (Universitat Autònoma de Barcelona. Laboratori de Fisiologia Vegetal) ; Poschenrieder, Charlotte (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Beebe, Stephen E (Centro Internacional de Agricultura Tropical) ; Rao, Idupulapati (Centro Internacional de Agricultura Tropical)
Common bean (Phaseolus vulgaris L. ) is the most important food legume in the diet of poor people in the tropics. Drought causes severe yield loss in this crop. Identification of traits associated with drought resistance contributes to improving the process of generating bean genotypes adapted to these conditions. [...]

Extreme climatic episodes, likely associated with climate change, often result in profound alterations of ecosystems and, particularly, in drastic events of vegetation die-off. Species attributes are expected to explain different biological responses to these environmental alterations. [...]

14 p, 747.8 KB Balancing the risks of hydraulic failure and carbon starvation : a twig scale analysis in declining Scots pine / Salmon, Yann (University of Edinburgh. School of GeoSciences) ; Torres-Ruiz, José M. (Institut National de la Recherche Agronomique (França)) ; Poyatos, Rafael (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Martínez Vilalta, Jordi, 1975- (Universitat Autònoma de Barcelona.

60 p, 4.7 MB Coupling a water balance model with forest inventory data to predict drought stress : the role of forest structural changes vs. climate changes / Cáceres Ainsa, Miquel de (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Martínez Vilalta, Jordi, 1975- (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Coll, Lluís (Centre Tecnològic Forestal de Catalunya) ; Llorens García, Pilar (Institut de Diagnosi Ambiental i Estudis de l'Aigua) ; Casals, Pere 1963- (Centre Tecnològic Forestal de Catalunya) ; Poyatos, Rafael (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Pausas, Juli G (Centro de Investigaciones sobre Desertificación) ; Brotons, Lluís (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Mechanistic water balance models can be used to predict soil moisture dynamics and drought stress in individual forest stands. Predicting current and future levels of plant drought stress is important not only at the local scale, but also at larger, landscape to regional, scales, because these are the management scales at which adaptation and mitigation strategies are implemented.

Well-defined productivity-precipitation relationships of ecosystems are needed as benchmarks for the validation of land models used for future projections. The productivity-precipitation relationship may be studied in two ways: the spatial approach relates differences in productivity to those in precipitation among sites along a precipitation gradient (the spatial fit, with a steeper slope); the temporal approach relates interannual productivity changes to variation in precipitation within sites (the temporal fits, with flatter slopes). [...]
