Figure 1: Plot-level measurements of change in aboveground
biomass according to parasite infection and snail density treatments.
Dashed line at zero indicates no change in aboveground biomass, positive
values indicate an increase in biomass during the study, and negative
values indicate a loss in biomass. Lines depict modeled relationships,
and associated shading represent 95% confidence intervals. The multiple
R2 for this relationship was 0.83, with an associated
correlation coefficient of 0.912.
