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).
