Litter chemistry explains contrasting feeding preferences of bacteria, fungi, and higher plants

Abstract Litter decomposition provides a continuous flow of organic carbon and nutrients that affects plant development and the structure of decomposer communities. Aim of this study was to distinguish the feeding preferences of microbes and plants in relation to litter chemistry. We characterized 3...
