Tunas are the focus of significant fisheries in the Pacific Ocean, where landings of four
species–skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), bigeye …

Abstract Skipjack (Katsuwonus pelamis), yellowfin (Thunnus albacares) and bigeye
(Thunnus obesus) tuna are the target species of tropical tuna fisheries in the Indian Ocean …

Genetic analyses have much to offer fisheries managers, especially in the provision of tools
enabling unequivocal specimen identification and assessment of stock structure. The three …

Comparative phylogeography has revealed remarkable patterns of concordance in the
maternal phylogenies of many species. The phylogeography and historical demography of …

Background Tuna species of the genus Thunnus, such as the bluefin tunas, are some of the
most important and yet most endangered trade fish in the world. Identification of these …

Although many coastal shark species have widespread distributions, the genetic
relatedness of worldwide populations has been examined for few species. The blacktip …

Background Yellowfin and skipjack tuna are globally distributed in the world's tropical and
sub-tropical oceans. Since little, if any, migration of these fishes occurs between the Atlantic …

Abstract Even though the Indo‐Malay Archipelago hosts the world's greatest diversity of
marine species, studies on the genetic population structure and gene flow of marine …

Sawfishes are among the most endangered of all elasmobranch species, a factor fostering
considerable worldwide interest in the conservation of these animals. However …

Different classes of molecular markers occasionally yield discordant views of population
structure within a species. Here, we examine the distribution of molecular variance from 14 …
