Fig. 6 in The hypothesis of adaptive radiation in evolutionary biology: hard facts about a hazy concept

Fig. 6 Frequency at which the different regions of the world were investigated. The number of occurrences for each area between 2003 and 2012 corresponds to the number of case studies (potentially several case studies per article) where a taxon has likely radiated in this given area (see Table 1). Mainland: light brown ≤50 and dark brown>50. Oceans: light green = [1–5] and dark green =]5–20]. Islands s.l. (ellipses): light blue (light gray in the printed version) = [1–5], dark blue (dark gray) =]5–25], and purple (medium gray)>25
