Effects of fire disturbance on soil respiration in the non-growing season in a Larix gmelinii forest in the Daxing'an Mountains, China. [PDF]

open access: yesPLoS ONE, 2017
In boreal forests, fire is an important part of the ecosystem that greatly influences soil respiration, which in turn affects the carbon balance.

Controls on ecosystem respiration of carbon dioxide across a boreal wetland gradient in Interior Alaska [PDF]

open access: yes, 2012
Thesis (M.S.) University of Alaska Fairbanks, 2012Permafrost and organic soil layers are common to most wetlands in interior Alaska, where wetlands have functioned as important long-term soil carbon sinks.

Soil respiration depending on different agricultural practices before maize sowing

open access: yesPlant, Soil and Environment, 2017
The aim of the study was to compare soil respiration depending on different agricultural practices before sowing of maize (Zea mays L.). Results of the study were derived from the field experiment that was carried out in 2013-2015; the research indicates

Forest Soil Respiration under Climate Changing [PDF]

open access: yes, 2018
The respiration of forest soils and the major factors controlling its rate are fairly well understood. The process is of utmost significance because its balance with the fixation of CO2 in the biomass defines whether a particular site is a source or sink of atmospheric CO2.

Mullahingamise sesoonne dünaamika kuusikute aegreas / Seasonal dynamics of soil respiration in a chronosequence of the Norway spruce stands

open access: yesMetsanduslikud Uurimused, 2011
Soil respiration resulting from microbial and root respiration is a major component of the forest carbon cycle. The response of soil respiration to varying environmental factors (soil temperature and soil moisture) was studied in a Norway spruce ...

Autotrophic and heterotrophic components of soil respiration caused by rhizosphere priming effects in a plantation

open access: yesPlant, Soil and Environment, 2017
Root-exudate inputs can stimulate the decomposition of soil organic carbon by priming microbial activity, but its ecological significance is still not fully understood.

Soil respiration in different agricultural and natural ecosystems in an arid region. [PDF]

open access: yesPLoS ONE, 2012
The variation of different ecosystems on the terrestrial carbon balance is predicted to be large. We investigated a typical arid region with widespread saline/alkaline soils, and evaluated soil respiration of different agricultural and natural ecosystems.

Bomb-14C analysis of ecosystem respiration reveals that peatland vegetation facilitates release of old carbon [PDF]

open access: yes, 2009
The largest terrestrial-to-atmosphere carbon flux is respired CO<sub>2</sub>. However, the partitioning of soil and plant sources, understanding of contributory mechanisms, and their response to climate change are uncertain.

Soil Respiration Characteristics and Influencing Factors of Shrub Ecosystem on the Loess Plateau

open access: yesRenmin Zhujiang, 2022
Soil respiration is one of the main sources of atmospheric carbon.In recent years,the vegetation cover of the Loess Plateau has changed significantly.To explore the change rules and influencing factors of soil respiration in the shrub ecosystem,this ...
