Splet06. nov. 2012 · If the mass-ratio hypothesis is correct, i.e. the actual decomposition rate equals the community-weighted value that is predicted from the monocultures, then β = 1 and σ δ = 0; there is no bias on average and no bias in any given litter mixture. Any other result means that the mass-ratio hypothesis is not strictly correct.
