FIGURE 5 in Vertebrate endemism in south-eastern Africa numerically redefines a biodiversity hotspot

FIGURE 5. Patterns of vertebrate endemism within the south-east Africa dominion defined by the dendrogram in Fig. 4a, comprising 28 operational graphical units (acronyms in pane (b) and labelled in Fig. 1. (a) south-east Africa dominion endemic species richness (south-east African endemism sensu stricto); (b) range-restricted species richness (narrow endemism); (c) weighted endemism (normalised); (d) weighted endemism per unit area (normalised). Each endemism measure is illustrated by a graduated grey scale of five classes, determined by natural breaks calculated using Jenk's optimisation.
