Influence of the Great Amazon Reef System and Pleistocene sea-level drops on the phylogeography of<i> Haemulon aurolineatum</i> (Haemulidae)
All four molecular markers revealed two distinct genetic groups: one predominantly distributed in the Northern province and the other mainly found in the Central, Southern Caribbean and Brazilian provinces. The divergence between these groups is estimated to have occurred around 800,000 years ago (Kya), this is attributed to the redirection of the Loop Current caused by climatic and oceanographic changes during the Pleistocene epoch. Our investigation has found genetic homogeneity among populations in the Central, Southern, and Brazilian provinces, which may be attributed to the ability of <i>H. aurolineatum</i> to migrate along the mesophotic reefs of the Great Amazon Reef System within the Amazonas-Orinoco plume region.
