15 p, 2.1 MB Species climatic niche explains drought-induced die-off in a Mediterranean woody community / Sapes, Gerard (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Serra Díaz, Josep M. (Harvard Forest (Research facility)) ; Lloret Maya, Francisco (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
During the last decades, plant die-off has been reported worldwide as a result of increased frequency and intensity of extreme drought events. From a niche perspective, a species performance should decrease as the climatic conditions defining a drought event differ from those characterizing the species climatic niche (the average conditions experienced by the species). [...]

The occurrence of multiple disturbances can jointly affect the recovery capacity of ecosystems, potentially leading to changes in vegetation dynamics or loss of resilience. The effects of interacting disturbances on ecosystems are, however, not well understood. [...]

14 p, 2.0 MB Assessment of the response of photosynthetic activity of Mediterranean evergreen oaks to enhanced drought stress and recovery by using PRI and R690/R630 / Zhang, Chao (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Preece, Catherine (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Filella, Iolanda (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The photochemical reflectance index (PRI) and red-edge region of the spectrum are known to be sensitive to plant physiological processes, and through measurement of these optical signals it is possible to use non-invasive remote sensing to monitor the plant photosynthetic status in response to environmental stresses such as drought.

Centrum výzkumu globální změny) ; Urban, Otmar (Akademie věd České Republiky. Centrum výzkumu globální změny) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Metabolomes, as chemical phenotypes of organisms, are likely not only shaped by the environment but also by common ancestry. If this is the case, we expect that closely related species of pines will tend to reach similar metabolomic solutions to the same environmental stressors. [...]

17 p, 3.0 MB Changes in the natural dynamics of Nothofagus dombeyi forests : population modeling with increasing drought frequencies / Molowny-Horas, Roberto (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Suárez, Maria Laura (Argentina. Consejo Nacional de Investigaciones Científicas y Técnicas) ; Lloret Maya, Francisco (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Drought-induced episodes of tree mortality can determine forest dynamics and structure, particularly in forests dominated by single species. Short- and mid-term climate projections indicate that strong changes in annual precipitation may strike more often in northern Patagonia. [...]

Laboratory of Plant Ecology) ; Martínez Vilalta, Jordi, 1975- (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Plant transpiration is the main evaporative flux from terrestrial ecosystems; it controls land surface energy balance, determines catchment hydrological responses and influences regional and global climate. [...]

Field experiments that expose terrestrial ecosystems to climate change factors by manipulations are expensive to maintain, and typically only last a few years. Plant biomass is commonly used to assess responses to climate treatments and to predict climate change impacts. [...]

We quantified springtime ecosystem-scale monoterpene fluxes from two similar Aleppo pine (Pinus halepensis Mill. ) forests, located in Israel, that differed in the amount of received precipitation: Yatir in the arid south and Birya in the northern part of Israel (291 and 755 mm annual average rainfall, respectively).

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The functional traits of plants in regions of the world with a Mediterranean climate have been shaped to tolerate periods of water deficit. These species are adapted to summer droughts but may not be able to cope with future increases in drought intensity, duration, and/or frequency. [...]
