Appendix D. Cross correlations among biological, chemical, and physical variables that are potential determinants of trematode prevalence and abundance.

Table D1. Pearson correlation matrix between all independent variables used in regression analyses to explain Ilyanassa obsoleta trematode abundance and diversity. Independent variables are transformed as necessary to eliminate or reduce deviations from normality (see Table 2). Colors indicate the strength (higher r values are brighter in color) and direction (blue indicates positive r, red indicates negative r) of pairwise correlations.
