TL;DR: While the diversity of primary substrate consumers did not notably increase with substrate complexity, consumer succession and secondary trophic links to bacterivorous and fungivorous microbes resulted in increased food web complexity in the more recalcitrant substrates, suggesting that consumer succession as well as intra- and inter-kingdom cross-feeding should be considered as mechanisms supporting food web complex in the detritusphere.

TL;DR: In this paper, the authors analyzed microbial biomass as phospholipid fatty acids (PLFAs) and enzyme activities involved in the C-cycle (β-glucosidase, N-acetyl-β- d -glucosaaminidase and β-xylosidases, phenol- and peroxidase) across a depth transect over a period of two years, and found that wheat cultivation resulted in higher bacterial and fungal biomass as well as higher enzyme activities at most sampling dates in comparison to maize cultivated plots,

TL;DR: In this paper, root and shoot litter residues were quantified in soil organic, extractable, microbial and fungal C pools using the shift in C stable isotope values associated with replacing C3 by C4 plants and followed root- vs. shoot litter-derived C resources into different soil C pools.

TL;DR: C transfers from fungi into higher trophic levels of the fungal energy pathway, that is fungal-feeding nematodes and meso- and macrofauna decomposers, by far exceed that of bacterial C, challenges previous views on the dominance of bacteria in root C dynamics.

TL;DR: Food web structure was more affected by the abiotic (soil profile) and biotic (crop plant) environment than by the supply with litter resources, with only small amounts of carbon conserved at higher trophic levels.
