Figure 5.

The distribution of diet specialisation among seed predator species displayed as (a) frequency histograms of d’ values of individual species in the food web focusing on the 50‐ha plot (displayed separately for Coleoptera and Lepidoptera) and (b) diet richness of seed predators using the full material (including insect and plant species not included in the food web). In panel (b), the histograms show the number of seed predator species in the data set reared from 1, 2, (…) and 7 plant species. Since the documented diet richness depends on sampling effort, the proportions of insect species in each diet richness category being singletons, species represented by 2–9 individuals, and species with ≥ 10 individuals are shown.
