Stef Bokhorst, Johan Asplund, Paul Kardol, and David A. Wardle. 2015. Lichen physiological traits and growth forms affect communities of associated invertebrates. Ecology 96:23942407. http://dx.doi.org/10.1890/14-1030.1

Appendix C. Correlations coefficients (r) between invertebrate abundance and lichen traits.

Table C1. Correlations coefficients (r) between invertebrate abundance and lichen traits, with each lichen species representing an independent data point. Significant correlations are presented in bold; * P < 0.05, ** P < 0.01. N = nitrogen concentration, P = phosphorus concentration, CBSCs = Carbon-based secondary compounds, WC = % water at saturation, PC1, PC2 = scores from the first and second axis of Principal Component Analysis.
