Complex patterns of genetic population structure in the mouthbrooding marine catfish, Bagre marinus, in the Gulf of Mexico and U.S. Atlantic. [PDF]
Ecol EvolAbstract Patterns of genetic variation reflect interactions among microevolutionary forces that vary in strength with changing demography. Here, patterns of variation within and among samples of the mouthbrooding gafftopsail catfish (Bagre marinus, Family Ariidae) captured in the U.S.

DNA barcoding of marine rocky reef fishes from northern Peru suggests a parapatric speciation in the Tropical Eastern Pacific. [PDF]
Ecol EvolUsing a DNA barcoding technique we found evidence that reinforce the hypotheses of how parapatric speciation could drive the origin of new species in the TEP. Abstract Northern Peru marks the end of an extensive coastal marine region: The Panama province, which is characterized by predominantly tropical and equatorial features and is home to the only ...

The complete mitochondrial genome of Arius arius (Siluriformes: Ariidae). [PDF]
Mitochondrial DNA B Resour, 2016 The threadfin sea catfish (Arius arius) belongs to the genus Arius in Ariidae. In this paper, we initially determined the complete mitochondrial genome of Arius arius. The mitochondrial genome is 16, 711 bp in length, with the base composition on the heavy strand: A - 29.67%, T - 25.38%, C - 29.70% and G - 15.25%.
