Statistics
Resistance was defined as the natural logarithm of the ratio of
Bray-Curtis distance between O-U1 to T1-U1, the resilience was defined
as natural logarithm of ratios of Bray-Curtis distance between T1-U1 to
T2-U2, as shown in Fig. S1.
Network analyses were conducted in in a pipeline
(http://www.magichand.online/h5-BioCloud-site/#/) and visualized
by Cytoscape 3.3.0 (http://cytoscape.org/). The cutoff threshold was set
at 0.9, top 100 relative abundance OTUs of the bacterial and fungal
community were selected for network analysis by Spearman correlation
matrix. The interaction type ratio was defined as the proportion of
positive interactions to all interactions (P%). Thus, a P% of
approximately 0.5 indicated relatively equal (balanced) proportions of
positive and negative interactions, while a P% near 1 or 0 indicate an
exceedingly high proportion of positive or negative interactions,
respectively. The significant difference of basic soil properties and
diversity indexes among ecosystems were checked using one-way ANOVA
test. PCoA analysis were based on Bray-Curtis distance, was performed
using a pipeline
(http://www.magichand.online/h5-BioCloud-site/#/). In order to
unify bacterial and fungal richness, we used the standard richness for
relative analysis, which was defined as the ratio of richness to the
lowest richness from bacterial and fungal samples, here is the fungal
community richness of the 3rd sample of bare land
(only 563).
