Abstract EN
Soil respiration (Rs) is a major pathway for carbon cycling and is a complex process involving abiotic and biotic factors.
Biological soil crusts (BSCs) are a key biotic component of desert ecosystems worldwide.
In desert ecosystems, soils are protected from surface disturbance by BSCs, but it is unknown whether Rs is affected by disturbance of this crust layer.
We measured Rs in three types of disturbed and undisturbed crusted soils (algae, lichen, and moss), as well as bare land from April to August, 2010, in Mu Us desert, northwest China.
Rs was similar among undisturbed soils but increased significantly in disturbed moss and algae crusted soils.
The variation of Rs in undisturbed and disturbed soil was related to soil bulk density.
Disturbance also led to changes in soil organic carbon and fine particles contents, including declines of 60–70% in surface soil C and N, relative to predisturbance values.
Once BSCs were disturbed, Q10 increased.
Our findings indicate that a loss of BSCs cover will lead to greater soil C loss through respiration.
Given these results, understanding the disturbance sensitivity impact on Rs could be helpful to modify soil management practices which promote carbon sequestration.
