Appendix E. Figures showing (a) distance-based RDA ordination of first and second fitted axes relating the environmental variables to the faunal data and (b) distance-based RDA as in (a), but showing the first and third axes.

 
   FIG. E1. (a) Distance-based RDA ordination of first and second fitted axes relating the environmental variables to the faunal data. Biplot projections are given for the environmental variables listed in Appendix A. Arrows are plotted showing the correlations of environmental variables with RDA axis 1 () and RDA axis 2 (), with the length and direction of the arrow representing the strength and direction of the relationship. Symbols for arrows having length
() less than 0.5 were not included. The first three dbRDA axes explained 11.5 %, 10.2 %, and 8.5 % of the fitted relationship, respectively. (b) Distance-based RDA as in (a), but showing the first and third axes.
