Els boscos són dels ecosistemes terrestres més importants en termes de fotosíntesi i segrest de carboni, perquè n'acumulen i en segresten en grans quantitats, com a biomassa i com a matèria orgànica del sòl. [...]
Forests are among the most important terrestrial ecosystems in terms of photosynthesis and carbon sequestration because they accumulate and sequester large amounts of carbon, both as living tissues and as soil organic matter. [...]

Departement Biologie) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
Fruit production (NPPf), the amount of photosynthates allocated to reproduction (%GPPf) and their controls for spatial and species-specific variability (e. g. nutrient availability, climate) have been poorly studied in forest ecosystems. [...]

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Weather and its lagged effects have been associated with interannual variability and synchrony of fruit production for several tree species. Such relationships are used often in hypotheses relating interannual variability in fruit production with tree resources or favourable pollinating conditions and with synchrony in fruit production among sites through the Moran effect (the synchronisation of biological processes among populations driven by meteorological variability) or the local availability of pollen.

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).

Shifts in ecosystem phenology play an important role in the definition of inter-annual variability of net ecosystem carbon uptake. A good estimate at the global scale of ecosystem phenology, mainly that of photosynthesis or gross primary productivity (GPP), may be provided by vegetation indices derived from MODIS satellite image data.

Recent warming significantly advanced leaf onset in the northern hemisphere. This signal cannot be accurately reproduced by current models parameterized by daily mean temperature (Tmean). Here using in situ observations of leaf unfolding dates (LUDs) in Europe and the United States, we show that the interannual anomalies of LUD during 1982–2011 are triggered by daytime (Tmax) more than by nighttime temperature (Tmin).
