"Therefore, the abun- dant soil microbial taxa do not appear to exhibit a high degree of functional redundancy (or equiv- alence), as is often assumed (19); reductions in tax- onomic diversity were associated with decreases in the breadth of functional traits contained with- in these soil communities."\cite{Fierer_2013}  "2) there is a common decomposition sequence independent of plant inputs or other ecosystem properties; and 3) molecular decomposition sequences, although consistent, are not uni- form and can be altered, resulting in measurable and functional changes in soil C."\cite{Grandy_2008}  "We determinedthat simple substrateswere degradedby the same groups of organisms in both soils, and at similar rates, but pine litter was degraded by different microbial groups in the two soils, and at different rates. Thus as substrate complexity increased, the functional group responsible for its degradation became more distinct between the two soils."\cite{Waldrop_2004}
