The ratio of soil autotrophic-to-heterotrophic respiration (or R a/R h) varies as a function of
trade-offs between the production (release) of carbon dioxide (CO 2) by both (i) plant roots …

The flux of carbon dioxide from the soil to the atmosphere (soil respiration) is one of the
major fluxes in the global carbon cycle. At present, the accumulated field observation data …

Summary The Soil Respiration Database (SRDB) is a near-universal compendium of
published soil respiration (Rs) data. The database encompasses published studies that …

Background An acceleration of model-data synthesis activities has leveraged many
terrestrial carbon datasets, but utilization of soil respiration (RS) data has not kept pace …

Soil microbial respiration (Rh) is a large but uncertain component of the terrestrial carbon
cycle. Carbon–climate feedbacks associated with changes to Rh are likely, but Rh …

Soil autotrophic respiration (RA) is one of the key components of carbon and nutrient cycling
in terrestrial ecosystems. Despite conflicting findings on the dominant climatic, edaphic and …

Accurately scaling soil respiration (SR, the soil-to-atmosphere flow of CO 2) across time and
space is important to constrain and understand ecosystem to global scale SR, the largest …

Soil respiration (R s) is a key process in the terrestrial carbon cycle. Measurement and
simulation of R s has received much attention recently. We collected annual R s field …

Soil respiration (R s) represents the largest flux of CO2 from terrestrial ecosystems to the
atmosphere, but its spatial and temporal changes as well as the driving forces are not well …

Soil respiration (Rs; the soil surface‐to‐atmosphere CO2 flux) has been measured in the
field for decades, but only recently have we begun to assemble and leverage these small …
