AbstractDespite decades of research, how climate warming alters the global flux of soil respiration is still poorly characterized. Here, we use meta‐analysis to synthesize 202 soil respiration datasets from 50 ecosystem warming experiments across multiple terrestrial ecosystems.

Drought alters respired δ13CO2 from autotrophic, but not heterotrophic soil respiration
Soil Biology and Biochemistry, 2012Many researchers are interested in the variability of root-respired δ 13 CO 2 as an indication of linkages between belowground plant respiration and canopy processes. Most studies in this area have, however, relied upon the assumption that temporal variability of total soil respired δ 13 CO 2 reflects autotrophic soil processes, but in fact few ...

AbstractMultiple lines of existing evidence suggest that increasing CO2 emission from soils in response to rising temperature could accelerate global warming. However, in experimental studies, the initial positive response of soil heterotrophic respiration (RH) to warming often weakens over time (referred to apparent thermal acclimation).

Thermal adaptation of heterotrophic soil respiration in laboratory microcosms
Global Change Biology, 2010AbstractRespiration of heterotrophic microorganisms decomposing soil organic carbon releases carbon dioxide from soils to the atmosphere. In the short term, soil microbial respiration is strongly dependent on temperature. In the long term, the response of heterotrophic soil respiration to temperature is uncertain.

Widespread asymmetric response of soil heterotrophic respiration to warming and cooling
Science of The Total Environment, 2018Soil is the largest organic carbon (C) pool in terrestrial ecosystems. Periodic changes in environmental temperature occur diurnally and seasonally; yet, the response of soil organic matter (SOM) decomposition to varying temperatures remains unclear. In this study, we conducted a modified incubation experiment using soils from 16 forest ecosystems in ...

Thermal Compensatory Response of Soil Heterotrophic Respiration Following Wildfire
Environmental Science & TechnologyFrequent wildfires pose a serious threat to carbon (C) dynamics of forest ecosystems under a warming climate. Yet, how wildfires alter the temperature sensitivity (Q10) of soil heterotrophic respiration (Rh) as a critical parameter determining the C efflux from burned landscapes remains unknown.

Heterotrophic respiration causes seasonal hysteresis in soil respiration in a warm-temperate forest
Journal of Forest Research, 2012To assess the effect of changes in organic litter stock on seasonal changes in heterotrophic respiration (R H), soil respiration (R S), and total ecosystem respiration (R E), we measured seasonal changes in leaf litter respiration (R LL) by the chamber method and estimated the seasonal ...

Abstract Decline in soil biodiversity associated with anthropogenic activities has raised concerns about the consequences for ecosystem functions. It remains uncertain how important soil microbial diversity is relative to abiotic factors, and how they interact, in driving ecosystem processes.

Science of The Total Environment, 2018
Quantifying soil respiration (Rs) and its components [autotrophic respiration (Ra) and heterotrophic respiration (Rh)] in relation to forest management is vital to accurately evaluate forest carbon balance. Thus, Rs, Ra, and Rh were continuously monitored from November 2013 to November 2016 in Pinus massoniana forests subjected to four different ...
