Table 2. A summary of small mammal community structure (mean value ± standard error) across four grazing levels (n = 15 for each) in the Hulunber meadow steppe.
Relative abundance was represented by number of individuals captured in a pen. Means with different letters after the error data are statistically different (Tukey HSD tests for post-hoc comparisons).
