Toward an ecological classification of soil bacteria.
TL;DR: Survey, experimental, and meta-analytical results suggest that certain bacterial phyla can be differentiated into copiotrophic and oligotrophic categories that correspond to the r- and K-selected categories used to describe the ecological attributes of plants and animals.
The influence of soil properties on the structure of bacterial and fungal communities across land-use types
TL;DR: Soil pH was the best predictor of bacterial community composition across this landscape while fungal community composition was most closely associated with changes in soil nutrient status, suggesting specific changes in edaphic properties, not necessarily land-use type itself, may best predict shifts in microbialcommunity composition across a given landscape.
Comparative metagenomic, phylogenetic and physiological analyses of soil microbial communities across nitrogen gradients.

TL;DR: The results suggest that N fertilization may, directly or indirectly, induce a shift in the predominant microbial life-history strategies, favoring a more active, copiotrophic microbial community, a pattern that parallels the often observed replacement of K-selected with r-selected plant species with elevated N.

TL;DR: In this paper, a new conceptual model that explicitly identifies the processes controlling soil organic matter availability for decomposition and allows a more explicit description of the factors regulating OM decomposition under different circumstances is presented.

Soil-carbon response to warming dependent on microbial physiology
TL;DR: In this article, the authors explore the mechanisms using a microbial-enzyme model to simulate the responses of soil carbon to warming by 5'∘C. They find that declines in microbial biomass and degradative enzymes can explain the observed attenuation of soil-carbon emissions in response to warming.
