Mitochondrial DNA genome evidence for the existence of a third divergent lineage in the western Atlantic Ocean for the bull shark ( Carcharhinus leucas)

Abstract We report for the first time a highly divergent lineage in the Caribbean Sea for the bull shark ( Carcharhinus leucas ) based on the analysis of 51 mitochondrial DNA genomes of individuals collected in the western North Atlantic. When comparing the mtDNA control region obtained from the mit...

Description
Summary:Abstract We report for the first time a highly divergent lineage in the Caribbean Sea for the bull shark ( Carcharhinus leucas ) based on the analysis of 51 mitochondrial DNA genomes of individuals collected in the western North Atlantic. When comparing the mtDNA control region obtained from the mitogenomes to sequences reported previously for Brazil, the Caribbean lineage remained highly divergent. These results support the existence of a discrete population in Central America due to a phylogeographic break separating the Caribbean Sea from the western North Atlantic, Gulf of Mexico and South America.
