FIG. B1. Bottomland site. Rarefaction curve plotting number of species observed vs. number of individuals counted for tree species at the bottomland site. Plots were enriched with endophyte-infected tall fescue (E+, filled symbols) or endophyte-free tall fescue (E-, open symbols). Data were collected in May 2006. Bars indicate 95% confidence intervals, and bars that overlap the mean for the alternative treatment indicate that differences between the treatments are not significant.
