Using 139 flux studies, we addressed the variability of net ecosystem surface assimilation (A(smax)), net ecosystem surface respiration (R-smax), as well as net surface evapotranspiration (E-smax) among and within vegetation types. While forests and C-3 crops, particularly in the northern hemisphere, have been preferentially investigated, information on tropical forests, C-4 grasslands or wetlands is rather limited. Almost no data are available for disturbed sites. Despite large variations within a vegetation type, enclosure studies tended to give highest A(smax) rates compared to micrometeorological techniques. Excluding enclosure studies, we tested the effect of stand age and leaf area index (LAI) on net ecosystem gas exchange. For grassl...
