Soil microorganisms shape global element cycles in life and death. Living soil microorganisms
are a major engine of terrestrial biogeochemistry, driving the turnover of soil organic …

Due to their substantial volume, subsoils contain more of the total soil carbon (C) pool than
topsoils. Much of this C is thousands of years old, suggesting that subsoils offer considerable …

Not only do soils provide 98.7% of the calories consumed by humans, they also provide
numerous other functions upon which planetary survivability closely depends. However, our …

Multiple lines of existing evidence suggest that climate change enhances root exudation of
organic compounds into soils. Recent experimental studies show that increased exudate …

Terrestrial ecosystems remove about 30 per cent of the carbon dioxide (CO 2 ) emitted by
human activities each year 1 , yet the persistence of this carbon sink depends partly on how …

Life is mostly composed of the elements carbon, hydrogen, nitrogen, oxygen, sulfur, and
phosphorus. Although these six elements make up nucleic acids, proteins, and lipids and thus …

Frequent high-amplitude redox fluctuation may be a strong selective force on the phylogenetic
and physiological composition of soil bacterial communities and may promote metabolic …

… ) was performed on whole community DNA extracted from 0.5 g soil with the Fast DNA
Spin Kit for Soil (Bio 101 Systems, Carlsbad, CA) according to methods described in PettRidge …

Arbuscular mycorrhizal fungi ( AMF ) perform an important ecosystem service by improving
plant nutrient capture from soil, yet little is known about how AMF influence soil microbial …

Microbial communities can potentially mediate feedbacks between global change and
ecosystem function, owing to their sensitivity to environmental change and their control over …
