Sammanfattning
F-GPP adjusted for the length of the carbon uptake period decreased at the sampling sites across functional types in the order C-4 crops, temperate and boreal deciduous forests (7.5-8.3 g C m(-2) per day) > temperate conifers, C-3 grassland and crops (5.7-6.9 g C m(-2) per day) > boreal conifers (4.6 g C m(-2) per day). Annual F-GPP and not ecosystem productivity (F-NEP) decreased across climate zones in the order tropical > temperate > boreal, However, the decrease in with latitude was greater than the decrease in F-GPP, indicating a larger contribution of respiratory (especially heterotrophic) processes in boreal systems.
