Other claims from this paper (9)
- Method / resource Litterbag data and estimated model parameters suggest a less steep oxic-to-anoxic decomposition-rate gradient than standard parameters.
- Method / resource Estimated parameters imply larger anaerobic decomposition rates for several species than standard parameters.
- Method / resource Maximum possible species decomposition rates vary more than standard plant-functional-type parameters suggest.
- Method / resource Estimated parameter differences can yield up to 100 kg m−2 difference in predicted 5000-year carbon accumulation.
- Method / resource The standard-parameter HPM decomposition module fits litterbag-derived Sphagnum decomposition rates.
- Method / resource Estimated-parameter model versions had equivalent fit to the standard-parameter version.
- Mechanism Errors in remaining mass and experiment design support a range of leaching-loss and decomposition-rate estimates.
- Recommendation Improved litterbag experiments are needed for more accurate model tests and parameter estimates.
- Method / resource The modeling approach can combine other data sources and decomposition modules.
