Nuclear and mitochondrial data reveal high genetic divergence among Atlantic and Mediterranean populations of the Iberian killifish Aphanius iberus (Teleostei: Cyprinodontidae).

Abstract excerpt

The molecular divergence and phylogenetic relationships of the Iberian populations of Aphanius iberus were established using allozymes and the complete cytochrome b gene sequence. Congruent results were found with both nuclear and mitochondrial molecular markers. The Mediterranean and Atlantic populations are clearly differentiated into two independent lineages. Their high molecular divergence suggests an early...
