Global spatiotemporal distribution of soil respiration modeled using a global database [PDF]

open access: yesBiogeosciences, 2015
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 cover a wide range of geographical locations and climate conditions ...

Soil respiration and its influencing factors in different land use types in desertification mining areas

open access: yesMeitan xuebao, 2023
In-depth understanding of the diurnal variation of soil respiration and its influencing factors at different depths under different land use patterns in desertified open-pit mines is crucial to assessing the carbon cycle of ecosystems in ecologically ...

Comparing an exponential respiration model to alternative models for soil respiration components in a Canadian wildfire chronosequence (FireResp v1.0) [PDF]

open access: yesGeoscientific Model Development, 2021
Forest fires modify soil organic carbon and suppress soil respiration for many decades after the initial disturbance. The associated changes in soil autotrophic and heterotrophic respiration from the time of the forest fire, however, are less well ...

Soil respiration strongly offsets carbon uptake in Alaska and Northwest Canada

open access: yes, 2021
Soil respiration (i.e. from soils and roots) provides one of the largest global fluxes of carbon dioxide (CO2) to the atmosphere and is likely to increase with warming, yet the magnitude of soil respiration from rapidly thawing Arctic-boreal regions is ...

Impacts of land-use changes on soil respiration in the semi-arid region of Brazil [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 2020
Soil respiration represents the largest flux of CO2 emission from terrestrial ecosystems, being affected by land-use changes and soil properties. There are few studies investigating the response of soil respiration to land-use changes in the Caatinga ...

Effect of sieving on ex-situ soil respiration of soils from three land use types [PDF]

open access: yes, 2020
This study aims to investigate the effect of sieving on ex situ soil respiration (CO2 flux) measurements from different land use types. We collected soils (0–10 cm) from arable, grassland and woodland sites, allocated them to either sieved (4-mm mesh ...

Rainfall intensification increases the contribution of rewetting pulses to soil heterotrophic respiration [PDF]

open access: yesBiogeosciences, 2020
Soil drying and wetting cycles promote carbon (C) release through large heterotrophic respiration pulses at rewetting, known as the “Birch” effect. Empirical evidence shows that drier conditions before rewetting and larger changes in soil moisture at ...

Response of Bare Soil Respiration to Air and Soil Temperature Variations According to Different Models: A Case Study of an Urban Grassland

open access: yesLand, 2023
Soil respiration is an important component of the global carbon cycle and is highly responsive to disturbances in the environment. Human impacts on the terrestrial ecosystem lead to changes in the environmental conditions, and following this, changes in ...

Spatial and temporal variations in global soil respiration and their relationships with climate and land cover

open access: yesScience Advances, 2020
Land-cover change exerts more influence on soil respiration in boreal and temperate regions than climate change. Soil respiration (Rs) represents the largest flux of CO2 from terrestrial ecosystems to the atmosphere, but its spatial and temporal changes ...

Soil respiration patterns and rates at three Taiwanese forest plantations: dependence on elevation, temperature, precipitation, and litterfall

open access: yesBotanical Studies, 2017
Background Soil respiration contributes to a large quantity of carbon emissions in the forest ecosystem. In this study, the soil respiration rates at three Taiwanese forest plantations (two lowland and one mid-elevation) were investigated.
