Abstract Terrestrial ecosystems release~ 106–130 PgC yr–1 into the atmosphere through
respiration, counterbalancing photosynthetic carbon uptake and determining the strength of …

This chapter reviews the state of the art of the general and specific criteria used to determine
microbiological activity in soil and to emphasize the exact meaning of each measurement …

We review measured rates of soil respiration from terrestrial and wetland ecosystems to
define the annual global CO2 flux from soils, to identify uncertainties in the global flux …

Soil respiration is the primary path by which CO 2 fixed by land plants returns to the
atmosphere. Estimated at approximately 75× 10 15 gC/yr, this large natural flux is likely to …

The oxygen isotopic composition of modern soil carbonate is well correlated with the
isotopic composition of local meteoric water. The carbon isotopic cycle for CO 2 in soils can …

We use semi‐mechanistic, empirically based statistical models to predict the spatial and
temporal patterns of global carbon dioxide emissions from terrestrial soils. Emissions …

Soil respiration–RS, the flux of CO 2 from the soil to the atmosphere–is probably the least
well constrained component of the terrestrial carbon cycle. Here we introduce the SRDB …

The climatic controls on the stable carbon isotopic composition (δ 13 C) of speleothem
carbonate are less often discussed in the scientific literature in contrast to the frequently …

Assessing the global C budget requires a better understanding of the effect of temperature
on soil CO2 efflux both from experiments and developments in theory. Intact soil cores (ca …

We used a climate‐driven regression model to develop spatially resolved estimates of soil‐
CO2 emissions from the terrestrial land surface for each month from January 1980 to …
