Microbial modulators of soil carbon storage: integrating genomic and metabolic knowledge for global prediction

TL;DR: Soil fungal and bacterial communities reflect differently tundra vegetation state transitions and soil physico-chemical properties, highlighting the importance of plant-soil interactions in ecosystem dynamics.

TL;DR: Increasing plant species diversity suppresses free-living N2 fixation in litter and soil of a subtropical karst forest. Higher plant species diversity decreases the abundance of the nifH gene and diazotrophic community diversity in soil, leading to a decrease in free-living N2 fixation rate.

TL;DR: For example, the authors found that across generations of chronic warming, genomic signatures within diverse bacterial lineages reflect trait-based adaptations related to growth and carbon utilization, and observed differences in global codon usage bias between heated and control genomes.

TL;DR: In this paper , the authors present a framework that facilitates the transition from intensive conventional to more regenerative farming practices by considering soil's natural cycle and the scale of the problem of soil degradation and the timescales involved in rebuilding soils and barriers to implementation.

TL;DR: This work has suggested that several environmental constraints obscure the intrinsic temperature sensitivity of substrate decomposition, causing lower observed ‘apparent’ temperature sensitivity, and these constraints may, themselves, be sensitive to climate.

TL;DR: In this article, a new generation of experiments and soil carbon models were proposed to predict the SOM response to global warming, and they showed that molecular structure alone alone does not control SOM stability.

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.

TL;DR: Soils collected across a long-term liming experiment were used to investigate the direct influence of pH on the abundance and composition of the two major soil microbial taxa, fungi and bacteria, and both the relative abundance and diversity of bacteria were positively related to pH.
