Influence of Disturbance on Soil Respiration in Biologically Crusted Soil during the Dry Season

Table 2

The effects of soil cover type (𝐶), measurement time (𝑇), and their interactions (𝐶×𝑇) on mean daily Rs (𝜇mol m⁻² s⁻¹) in the three biocrusted soil cover areas.

	Algae crust cover area			Lichen crust cover area			Moss crust cover area
	df	𝐹	𝑃	df	𝐹	𝑃	df	𝐹	𝑃
𝐶	2	33.65	0.046	2	8.33	0.052	2	37.39	<0.010
𝑇	8	39.27	<0.001	8	201.70	<0.001	8	26.94	<0.001
𝐶×𝑇	16	5.59	<0.001	16	4.62	<0.05	16	4.34	<0.050

df is degree of freedom; 𝐹: 𝐹-test; 𝑃 is the significance level at <0.05.
