117 p, 1.4 MB Plant ecophysiological responses to a field experimental drought in the Prades holm oak forest / Ogaya Inurrigarro, Romà (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Peñuelas, Josep, dir. (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
S'ha muntat un sistema experimental a l'alzinar de Prades per simular la sequera prevista per a les properes dècades al bosc mediterrani. S'ha realitzat el seguiment de la fotosíntesi, la morfologia i demografia foliar, la fenologia i el creixement de les espècies llenyoses dominants. [...]
An experimental system was installed in Prades holm oak forest to simulate the drought conditions predicted for the next decades in Mediterranean forests. Photosynthetic activity, leaf morphology and demography, phenology and growth of the dominant woody species are monitored. [...]

Key Laboratory of Horticulture Science for Southern Mountainous Regions) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
Global warming and recurring drought are expected to accelerate water limitation for plant communities in semiarid Mediterranean ecosystems and produce directional shifts in structure and composition that are not easily detected, and supporting evidence is scarce. [...]

Warmer temperatures and extended drought in the Mediterranean Basin are becoming increasingly important in determining plant physiological processes and affecting the regional carbon budget. The responses of plant physiological variables such as shoot water potential (Ψ), carbon-assimilation rates (A), stomatal conductance (gs) and intrinsic water-use efficiency (iWUE) to these climatic regimes, however, are not well understood.

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. [...]

Ozone concentrations in the Pyrenees have exceeded the thresholds for forest protection since 1994. We surveyed the severity of visible O₃ injuries, crown defoliation, and tree mortality of Pinus uncinata, the dominant species in subalpine forests in this mountain range, along two altitudinal and O₃ gradients in the central Catalan Pyrenees and analysed their relationships with the local environmental conditions.

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).

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
At the molecular level, folivory activity on plants has mainly been related to the foliar concentrations of nitrogen (N) and/or particular metabolites. We studied the responses of different nutrients and the whole metabolome of Quercus ilex to seasonal changes and to moderate field experimental conditions of drought, and how this drought may affect folivory activity, using stoichiometric and metabolomic techniques.

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. [...]
