Generally,scientists are challenged by relating the ecosystem
properties measured (here:net ecosystem exchange,biomass
above- and below-ground,carbon fixation by photosynthesis,
nutrient ratios) to ecosystem functions and services,such as
productivity,carbon fixation,nutrient cycling,decomposition
and water regulation.Measuring ecosystem services is a fastdeveloping
research area with many debates on how to assess
the services adequately.
