From: Plant diversity alters the representation of motifs in food webs
Frequency of motifs in food webs. Effect of sown plant species richness on mean counts of tri-trophic chain (a, s1), omnivory (b, s2), apparent competition (c, s4), exploitative competition (d, s5) and other motifs (e, i.e. sum of s3 and all double motif counts). 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). Linear models for e (other) could not be validated due to the bimodal distribution of the motif frequency
