Figure 1. Map of Floreana and surrounding islets showing study sites. Bathymetric contour lines delimit depths of 50 m (lighter blue), 100 m, 150 m, 200 m and >200m (darker blue). Inset map shows location of Floreana within the Galápagos archipelago.
Figure 2. Maximum likelihood gene trees of Microlophus (left) andPhyllodactylus (right) from the Galápagos Islands. Numbers next to branches correspond to bootstrap support values; for clarity, numbers in short branches are not shown. Species names followed by voucher (new sequences) or Genbank accession number and collection island are presented. Specimens from Floreana are in red, Champion in magenta, and Gardner in blue.
Figure 3. TCS networks of Floreana’s lava lizards (A, B) and leaf-toed geckos (C, D) based on mitochondrial genes ND2 and ND4, respectively. Networks A and C include all sampled sequences, whereas B and D exclude sequences containing significantly more undefined states than others as calculated by PopART (Leigh & Bryant, 2015). Numbers next to branches are number of mutations among haplotypes. Black circles are inferred haplotypes. Localities in Floreana are Black Beach (BB), Puerto Velasco Ibarra (PVI) and Post Office Bay (POB).
