Figure 2. Demographic models tested in MOMI2; bold arrows represent gene
flow bouts estimated for each model. Dark grey bar is S. c.
corvina, yellow bar is S. c. hicksii, red bar is S. c.
hoffmanni, and light grey bar is the ancestor. A) Model using the tree
topology and time of divergence obtained from the mitochondrial marker
ND2 (Ocampo et al., 2022a) to estimate effective population sizes. B-E)
Models including different bouts and pulses of gene flow to test for
contemporary gene flow between S. c. corvina and S. c.
hoffmanni , and to test for divergence in isolation of S. c.
corvina .
