Supplementary material to "A Synthesis of Sphagnum Litterbag Experiments: Initial Leaching Losses Bias Decomposition Rate Estimates"

Model version Considers 0 ?Decomposition equation Description Dataset model 1-1 Yes 3 One-pool exponential decomposition model which estimates decomposition rates and initial leaching losses.The model is a hierarchical model and estimates decomposition rates and initial leaching losses for individual litterbag replicates, combinations of species and studies, and species.Full dataset.model 1-2 Yes 3 Same as model 1-1.Full dataset excluding data from Bengtsson et al. (2017).model 1-3 Yes 5 Same as model 1-1, but uses equation 5. Full dataset.model 1-4 Yes 5 Same as model 1-3.Full dataset excluding data from Bengtsson et al. (2017).model 1-5 Yes 5 Same as model 1-3.Simulated data.model 1-6 Yes 5 Same as model 1-3.Simulated data, created with parameter values sampled from the posterior of model 1-4.model 2-1 No 2 Same as model 1-1, but ignores initial leaching losses.Full dataset.model 2-2 No 2 Same as model 2-1.Full dataset, excluding data from Bengtsson et al. (2017).model 2-3 No 4 Same as model 2-1, but uses equation 4. Full dataset.model 2-4 No 4 Same as model 2-3.Full dataset, excluding data from Bengtsson et al. (2017).All models used the following components to model the remaining mass of litterbag replicate conditional on the average remaining mass ( ) , the precision of remaining masses ( ), and decomposition rates (_1 ):for the mass remaining for sample , and precision = (1- ) 2 -1.58 α
