“…Natural hybridization and introgression are not uncommon in teleost fish (Witz 1999;Scribner et al 2001;Bossu and Near 2008). Recently, several studies reported evidence of hybridization and introgression events within the family Ictaluridae (Welsh and Cincotta 2004;Bossu and Near 2008;Keck and Near 2009), and more importantly between A. melas and A. nebulosus (Hunnicutt et al 2005). This may result in the origin of new hybrid species, with the hybrid possessing the mitochondrial haplotype of the maternal parent species (Witz 1999;Shearer et al 2002;Bossu and Near 2008).…”

-The black bullhead, Ameiurus melas of the family Ictaluridae, is a freshwater fish native to North America that was introduced throughout Europe in the late 1800s. Using mitochondrial DNA (mtDNA) as a genetic marker, the present study investigates the genetic structure and historical demography of A. melas in North America. MtDNA-based phylogenetic analyses revealed the existence of two distinct lineages (A and B) of A. melas. While lineage A clustered with the previously reported sequences of A. melas, lineage B emerged as a unique clade like other species of the genus Ameiurus. Individuals belonging to lineage B were mostly from the south central region of the United States, the region that never glaciated during the last Ice Age. Results of a fossil-based molecular clock analysis suggest that lineage A and the paraphyletic lineage B of A. melas diverged from their respective common ancestors approximately 3 (±0.2) and 15.9 (±1.3) million years ago. Lineage B could possibly be a hybrid species, possessing the mtDNA haplotype of its maternal parent, an Ameiurus species that has gone extinct. While lineage A showed evidence of population expansion, lineage B did not show any evidence of population expansion, but rather is comprised of geographically structured populations.
