Multiple scales of spatial heterogeneity control soil respiration responses to precipitation across a dryland rainfall gradient
Soil respiration was highly responsive to rainfall pulses, although soil surfaces and patch types often exerted more control on Rs than did rainfall pulses. Rainfall generally had proportionally greater influence on Rs with higher annual rainfall. Greater Rs occurred on stable than unstable soil surfaces and in depositional than erosional patch types.
