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

FIG.
E1. (a) Distancebased 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) Distancebased RDA as in (a), but showing the first and third axes.
