Figure 2. Relationship between R. niveus cover and species richness.

Figure 2

Lines within the box represent the median values of the number of species found within each cover category; the bottom and top edges of the box represent 25th and 75th percentiles of all data, respectively; the bottom and top bars represent 5th and 95th percentiles. ANOVA-GLM (quasi-Poisson error distribution); native species: F4,119 = 20.83, P<0.001; introduced species: F4,119 = 4.04, P<0.001 (a,bdenote group differences detected by statistical analyses amongst R. niveus cover categories).
