FIGURE 7 in At the lower size limit in snakes: two new species of threadsnakes (Squamata: Leptotyphlopidae: Leptotyphlops) from the Lesser Antilles
FIGURE 7. Evolution of extreme body size in island species. Vertical columns separated by dashed lines indicate ecological niches defined by body size. Individual symbols represent species whereas different types of symbols (triangles, circles, and squares) represent different taxonomic groups (e.g., genera, phyla, etc.). (A) A single colonizing species leads to an adaptive radiation (multiple species) on the island, some of which are extreme in size after filling of vacant niches. (B) A similar scenario, but in this case the colonizing species evolves an extreme body size by natural selection alone, without adaptive radiation.

FIGURE 14. Factorial Correspondence Analysis (FCA) of the genotypes of samples from four populations. Black squares: individuals introduced in Saint Lucia (Iguana rhinolopha) [n=8] circles: individuals endemic to Saint Lucia (Iguana iguana sanctaluciae), with white circles for individuals from Louvet (n=13) and hatched circles for individuals from Grand Anse (n=4); white triangles: individuals endemic to Grenadines (Iguana iguana insularis), [n=4]; and grey stars: individuals from French Guiana (Iguana iguana iguana) [n=7]. Only 7 circles are shown for the 17 'native' individuals from Saint Lucia because many individuals from Louvet and one from Grand Anse had the same genotypes.
