The deep soil organic carbon response to global change
Over 70% of soil organic carbon (SOC) is stored at a depth greater than 20 cm belowground.
A portion of this deep SOC actively cycles on annual to decadal timescales and is sensitive …

Practical guide to measuring wetland carbon pools and fluxes
Wetlands cover a small portion of the world, but have disproportionate influence on global
carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes …

Five years of whole-soil warming led to loss of subsoil carbon stocks and increased CO2 efflux
Subsoils below 20 cm are an important reservoir in the global carbon cycle, but little is
known about their vulnerability under climate change. We measured a statistically significant …

Ecosystem warming extends vegetation activity but heightens vulnerability to cold temperatures
Shifts in vegetation phenology are a key example of the biological effects of climate change,–
. However, there is substantial uncertainty about whether these temperature-driven trends …

Whole-soil-profile warming does not change microbial carbon use efficiency in surface and deep soils
The paucity of investigations of carbon (C) dynamics through the soil profile with warming
makes it challenging to evaluate the terrestrial C feedback to climate change. Soil microbes …

Differential responses of carbon‐degrading enzyme activities to warming: Implications for soil respiration
Extracellular enzymes catalyze rate‐limiting steps in soil organic matter decomposition, and
their activities (EEAs) play a key role in determining soil respiration (SR). Both EEAs and SR …
