    Modification of carbon cycle in forest ecosystems by distinct sky conditions

  • Original language description

    Light is one of the key drivers of photosynthesis and primary production by plants. In this chapter we present that sky conditions, and not just light intensity, may influence ecosystems? photosynthesis and have the potential to cause substantial changein the global carbon cycle. Cloudy sky conditions resulted in significantly greater ecosystem carbon uptake than was found at corresponding incident light intensities on clear-sky days. Shoot-level data showed that shoots from deep within the canopy substantially contributed to the overall carbon balance during cloudy days when enhanced diffuse radiation effectively penetrated into the lower parts of the canopy. In addition, convenient microclimatic conditions (i.e. lower vapour pressure deficits and temperatures) also contributed to higher ecosystem carbon uptake under cloudy sky conditions. Sky conditions thus have important direct effects on the productivity and structure of vegetation.
