Appendix E. Average epilithic standing crops from all injections for each of the three study sites.
TABLE E1. Average epilithic standing crops from all injections for each of the three study sites (n = 8, 8, and 6, respectively). Data are means ± SE. Value in parentheses is CV(coefficient of variation) = [(mean/SD)*100%]. Mean values with different superscripts within a row are significantly different (P < 0.005) as determined by Tukey’s Multiple Comparison Test following one-way ANOVA (site = main effect).
