TL;DR: It is argued that thresholds of disturbance are central to measuring resilience and linking thresholds to functional diversity indices may improve the ability to predict the resilience of ecosystems to future, potentially novel, disturbances according to their spatial and temporal scales of influence.

Tradeoffs in microbial carbon allocation may mediate soil carbon storage in future climates

Front. Microbiol., 4.

author keywords: carbon allocation; extracellular enzyme activity; climate change; microbial physiology; biomass stoichiometry
TL;DR: Soil microbes may differentially allocate C in changing environments by altering processes such as enzyme production, C use efficiency (CUE), or biomass stoichiometry, but because these mechanisms may operate simultaneously and interact, microbial physiological feedbacks on soil C storage are difficult to predict.
