From: Plant diversity alters the representation of motifs in food webs
Representation of motifs relative to null models. Effect of sown plant species richness on mean normalised z-scores for tri-trophic chain (a, s1), omnivory (b, s2), apparent competition (c, s4) and exploitative competition (d, s5). Filled points and solid lines show motif frequency in the full food web, and open points and dashed lines display frequency in the consumer sub-web (i.e. free-floating motifs). P values from linear mixed models (two-tailed test) for the slope of all displayed relationships are <0.001 (for full model results see Supplementary Table 1)
