Negative Soil Respiration Fluxes in Unneglectable Arid Regions

Effects of climate change on soil respiration and carbon processing in Mediterranean and semi-arid regions: An experimental approach

Recent regional climate-change models indicated significant changes in the temporal and spatial distribution of rainfall in the Mediterranean-Basin region. Understanding the consequences of rainfall alterations for soil respiration and carbon processing in these regions is essential, considering their crucial functions for soil fertility and ecosystem functioning. Our aim was to evaluate the ef...

Interannual variation in seasonal drivers of soil respiration in a semi-arid Rocky Mountain meadow

Semi-arid ecosystems with annual moisture inputs dominated by snowmelt cover much of the western United States, and a better understanding of their seasonal drivers of soil respiration is needed to predict consequences of climatic change on soil CO2 efflux. We assessed the relative importance of temperature, moisture, and plant phenology on soil respiration during seasonal shifts between cold, ...

Soil Respiration in Different Agricultural and Natural Ecosystems in an Arid Region

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. Soil respiration for five ecosystems together with soil temperature, soil moisture, soil pH, soil electric conductivity and soil organic carb...

Organic Matter and Water Addition Enhance Soil Respiration in an Arid Region

Climate change is generally predicted to increase net primary production, which could lead to additional C input to soil. In arid central Asia, precipitation has increased and is predicted to increase further. To assess the combined effects of these changes on soil CO2 efflux in arid land, a two factorial manipulation experiment in the shrubland of an arid region in northwest China was conducte...
