Figure 3
Plant productivity (plant metrics) when wireworms were present singly compared with the productivity across diverse communities (averaged over two- and three-species treatments).
Shown are the mean (A) shoot (aboveground) dry mass, (B) root dry mass, and (C) the number of produced seed heads (±SE) for L. infuscatus (Li), L. californicus (Lc), S. pruininus (Sp), and diverse treatments. The long dashed lines indicate the mean productivity averaged across the diverse communities, while dotted lines represent ±1 SE from this mean. Within each panel, asterisks indicate that the single-species caused significantly more damage to wheat plants than the average of the diverse treatments (based on one sample t-tests, α = 0.05).
