Release and recovery files from the world's five major constituent-based billfish
(Istiophoridae) tagging programs were assembled into a single composite database. Data …

Istiophorid billfishes are highly migratory species that inhabit the tropical and subtropical,
epipelagic waters of the world's oceans, a large, relatively homogeneous environment that …

Phylogeography is a discipline concerned with various relationships between gene
genealogies—phylogenetics—and geography. The word “phylogeography” was coined in …

Most surveys of mitochondrial DNA (mtDNA) in marine fishes reveal low levels of sequence
divergence between haplotypes relative to the differentiation observed between sister taxa …

The distribution of circumtropical marine species is limited by continental boundaries, cold
temperate conditions, and oceanic expanses, but some of these barriers are permeable over …

The movements of Atlantic bluefin tuna (Thunnus thynnus thynnus) have captured the
interest of scientists and fishers since the time of Aristotle. This tuna is unique among bony …

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

Many marine fishes are cosmopolitan, occurring in continuous (eg, circumtropical) or
discontinuous (eg, antitropical) distributions. Little is known of the genetic basis of …

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 …
