Table 3.
Final ANOVA tables after all three independent variables (Number of Sites, Number of Genera and Number of Species) were entered into the stepwise regression analysis. In all cases the regressions were significant with P < 0.0001. The degrees of freedom were as given in Table 2. The adjusted R2 value for each regression is given in parentheses after each dataset abbreviation.
