The niche equivalency values of the tick species in the Afrotropical region, as clustered by functional groups computer according a hierarchical clustering algorithm.

Each value is the climate niche equivalency among the species included in that group (e.g. 1×1) or among the species in different taxonomic clusters (e.g. 1×2). Numbering of the functional groups and the species included in each group follow the consecutively numbered labels of Figure 3.
