Interspecific variation in leaf litter tannins drives decomposition in a tropical rain forest of French Guiana.

abstract：:Animals can be important in modulating ecosystem-level nutrient cycling, although their importance varies greatly among species and ecosystems. Nutrient cycling rates of individual animals represent valuable data for testing the predictions of important frameworks such as the Metabolic Theory of Ecology (MTE) and ecol...
