Table 1 The effects of climate, initial litter quality, and experimental condition on the response of litter decomposition rate (k-value), mass loss, remaining potassium, calcium, and cellulose to forest gaps (refer to Supplementary Table 1 for litterfall and remaining carbon and other nutrients)
From: Global forest gaps reduce litterfall but increase litter carbon and phosphorus release
