Throughout Earth's history, drought has been a common crisis in terrestrial ecosystems; in
human societies, it can cause famine, one of the Four Horsemen of the apocalypse. As the …

In forest ecosystems, ectomycorrhizal and saprotrophic fungi play a central role in the
breakdown of soil organic matter (SOM). Competition between these two fungal guilds has …

Soil moisture strongly affects the dynamics of soil organic matter and is an important
environmental variable in all models predicting changes in soil carbon stocks from site to …

Soil heterotrophic respiration and nutrient mineralization are strongly affected by
environmental conditions, in particular by moisture fluctuations triggered by rainfall events …

Seasonally dry tropical forests (SDTF) are located in regions with alternating wet and dry
seasons, with dry seasons that last several months or more. By the end of the 21st century …

Stocks of soil organic carbon represent a large component of the carbon cycle that may
participate in climate change feedbacks, particularly on decadal and centennial timescales …

Soil moisture is an essential climate variable influencing land–atmosphere interactions, an
essential hydrologic variable impacting rainfall–runoff processes, an essential ecological …

Biological N2 fixation represents the major source of N input in agricultural soils including
those in arid regions. The major N2-fixing systems are the symbiotic systems, which can play …

Variation in soil temperature can account for most of the seasonal and diel variation in soil
CO2 efflux, but the temperature effect is not always consistent, and other factors such as soil …

In the next decades, many soils will be subjected to increased drying/wetting cycles or
modified water availability considering predicted global changes in precipitation and …
