Scatterplots showing results from the utilitarian diversity and redundancy null model analyses.

<p>(<b>A</b>). Functional diversity plot showing observed utilitarian diversity versus species richness. (<b>B</b>). Index of variance (IV) values for the utilitarian diversity indices versus species richness. A positive IV value indicates that observed utilitarian diversity is greater than expected utilitarian diversity while holding species richness constant (i.e., it indicates low utilitarian redundancy). Triangles indicate plots that were significantly greater than expected at α = 0.05. <i>N</i> = 56.
