Figure 2. A) Phylogeny and ancestral state estimations for the
global radiation of pigeons based on eight postdoc biogeographic
regions. Contemporary taxa that occur on continents (C) or islands and
continents (IC) within the fruit specialist Ptilinopini are numbered 1)P. reginae (IC), 2) P. superbus (IC), 3) P.
porphyreus (IC), 4) P. melanospilus (IC), 5) P. jambu(C), 6) P. magnificus (IC), 7) Ducula
bicolor /luctuosa complex (IC), 8) D. aenea complex (IC),
9) Ducula badia (C) and 10) Lopholaimus antarticus (C).
Nodes subtending potential older upstream colonisations in other clades
are indicated with asterisks. Figure S4 shows the full tree with tip
names and ancestral state reconstructions; B) lineage accumulation plots
for the eight biogeographic regions; C) endemic cladogenesis plots for
eight postdoc biogeographic regions. All biogeographic model result
plots show median values, with 50% confidence intervals indicated by
colour-shading.
