TL;DR: Analysis of microbial activities in Arctic and Antarctic soils indicated that fungal/bacterial interactions play a major, but causally unclear, role in structuring the soil microbial communities of which they are a part.

TL;DR: The results indicate that the effect of agrochemicals is not limited to the bulk microbial community but also includes the root endophytic community, and lower methanotroph richness was observed for mineral-fertilized plants than for organically fertilized plants.

TL;DR: The fact that the roots of newer wheat cultivars were aggressively colonized by endophytic pseudomonads suggests that these bacteria might be exploited as plant growth-promoting rhizosphere bacteria or as a means to establish specific catabolic activities in these plants.

TL;DR: The use of plants to reduce contaminant levels in soil is a cost-effective method of reducing the risk to human and ecosystem health posed by contaminated soil sites.

TL;DR: The response of three soil groups to anthropogenic perturbation is considered and the need for integrative studies which consider how environmental variables moderate interactions between functional groups, how this moderation affects biogeochemical processes and how these feedbacks ultimately drive ecosystem services provided by soil biota is suggested.
