Figure 1 The resistance and resilience of microbial community from
different terrestrial ecosystems. Fig. 1A depicts the magnitude of
resistance and resilience of the bacterial and fungal communities among
bare soil, grass, shrub, deciduous forest, and coniferous forest.
Different letters indicate significance (P < 0.05; one-way
ANOVA Tukey’s test). Fig. 1B and 1C depict the negative relationship
between resistance and resilience of the bacterial and fungal
communities, respectively.
As depicted in Fig. 1, the ecosystem with lowest bacterial resilience
was shrub (-0.86), which was not significantly different from grass and
bare soil (P > 0.05), but was significantly lower than
deciduous forest (0.06) and coniferous forest (-0.15, P <
0.05). Similarly, fungal resilience was lowest in shrub (-0.68), then
bare soil (-0.58), and both were significantly lower than coniferous
forest (0.46, P < 0.05), but not significantly lower than
grass and deciduous forest (P > 0.05). Bacterial resistance
was highest in shrub (0.46) and lowest in coniferous forest (-0.70), and
these two ecosystems were significantly different (P < 0.05)
from each other while the other 3 showed no significant differences
between them (P > 0.05). The highest fungal resistance was
observed in bare soil (0.28), and was significantly higher than in the
coniferous forest (-0.72, P < 0.05). Microbial resistance
showed a decreasing trend with vegetation types from bare soil, grass,
shrub, deciduous forest, to coniferous forest while the microbial
resilience showed an increasing trend. Linear regression analysis showed
a significantly negative relationship between resistance and resilience
in both the bacterial (Fig. 1B, P < 0.05,
R2=0.42, slope=-0.51) and fungal (Fig.1 C, P
< 0.05, R2=0.62, slope=-0.91) communities,
which indicated a trade-off between microbial community resistance and
resilience and that fungal communities were less likely to possess both
high resistance and resilience.
