Journal ArticleDOI
Nitrogen mineralization: challenges of a changing paradigm
TL;DR: A complete new conceptual model of the soil N cycle needs to incorporate recent research on plant–microbe competition and microsite processes to explain the dynamics of N across the wide range of N availability found in terrestrial ecosystems.
Journal ArticleDOI
Microbial stress‐response physiology and its implications for ecosystem function
TL;DR: It is suggested that more effectively integrating microbial ecology into ecosystem ecology will require a more complete integration of microbial physiological ecology, population biology, and process ecology.
Journal ArticleDOI
Variations in microbial community composition through two soil depth profiles
TL;DR: Using PLFAs as biomarkers, it is shown that Gram-positive bacteria and actinomycetes tended to increase in proportional abundance with increasing soil depth, while the abundances of Gram-negative bacteria, fungi, and protozoa were highest at the soil surface and substantially lower in the subsurface.
Journal ArticleDOI
The implications of exoenzyme activity on microbial carbon and nitrogen limitation in soil: a theoretical model
TL;DR: A simple theoretical model is built to explore the behavior of the decomposition–microbial growth system when the fundamental kinetic assumption is changed from first order kinetics to exoenzymes catalyzed decomposition (dC/dt=KC×Enzymes).

TL;DR: It is shown that terrestrial changes in summer albedo contribute substantially to recent high-latitude warming trends and the continuation of current trends in shrub and tree expansion could further amplify this atmospheric heating by two to seven times.
