Figure 3
Diversity profiles for butterflies (a), bumblebees (b), and plants (c). Each value of alpha represents a different biodiversity index: 0 = species richness, 1 = Shannon diversity, 2 = Simpson diversity and Inf = Berger-Parker. The indexes put different weights to rare and common species (i.e. rare species have the same weight as common species in alpha = 0 while Berger-Parker ignores rare species). Diversity is represented in Hill numbers, meaning that all indexes predict number of species and can thus be compared to each other. The bars represent the standard error of the mean. Note that the connections between points do not represent a relationship between indexes. Silhouette images were available under Public Domain license at PhyloPic (http://phylopic.org).
