Appendix B. Correlation matrix for the 79 environmental variables. Correlations in bold are significant at a Bonferroni corrected P value of 0.0006. Variables shaded in gray were removed from the ordination due to strong collinearity with one or more other variables (r > 0.9). Codes for variables are as in Table A1 (Appendix A). A tab-delimited ASCII text file of the table, which can be loaded into a spreadsheet such as Excel, can be downloaded. Click here on matrix.txt to download.
