Results of Wilcoxon nonparametric tests for differences in location of species’ density optima.

Comparisons of the locations of elevational density optima between southern and northern AWT relative to predicted values based on MAT, Tmax and Tmin from both bioCLIM and accuCLIM. P-values are the results of Wilcoxon tests of the null hypothesis of no difference between the observed location differences and those predicted based on the corresponding temperature gradient across elevation in each case. Tests that failed to reject H0 are shown in bold. RMSE values are those associated with a simple linear model of each species’ observed density optima against the corresponding predicted values.
