Biogeographic controversies surrounding the widespread freshwater fish, Galaxias maculatus, were addressed with DNA sequence data. Mitochondrial cytochrome b and 16S rRNA sequences were obtained from representatives of six populations of this species. Substantial levels of cytochrome b (maximum 14.6%) and 16S rRNA sequence divergence (maximum 6.0%) were detected between western Pacific (Tasmania-New Zealand) and South American (Chile-Falkland Islands) haplotypes. A considerable level of… 
Mitochondrial DNA phylogenetics of the Galaxias vulgaris complex from South Island, New Zealand: rapid radiation of a species flock
Molecular clock calibrations suggest that migratory and non-migratory forms of Galaxias vulgaris complex diverged no earlier than the mid-late Pliocene, and the unresolved relationships among species may reflect a rapid evolutionary radiation, essentially a star phylogeny.
Molecular phylogenetics and biogeography of galaxiid fishes (Osteichthyes: Galaxiidae): dispersal, vicariance, and the position of Lepidogalaxias salamandroides.
The species-rich genus Galaxias is shown to be polyphyletic and the generic taxonomy of the Galaxiinae is reassessed in the light of phylogenetic relationships, and the loss of this migratory phase may be a major cause of speciation.
Molecular Phylogeny and Phylogeography of the Australian Freshwater Fish Genus Galaxiella, with an Emphasis on Dwarf Galaxias (G. pusilla)
All populations experienced Late Pleistocene-Holocene population growth, possibly in response to the relaxation of arid conditions after the last glacial maximum, and high levels of genetic divergence and the discovery of new cryptic species have important implications for the conservation of this already threatened group of freshwater species.
Extreme levels of intra-specific divergence among Cape Peninsula populations of the Cape galaxias, Galaxias zebratus Castelnau 1861, reveals a possible species complex
Results suggest that periods of low sea level may have been important in creating opportunities and alternative routes for dispersal and migration for Cape Peninsula populations.
New Zealand triplefin fishes (family Tripterygiidae): contrasting population structure and mtDNA diversity within a marine species flock
Overall, a strong relationship was found between habitat depth and population structure among species, and species inhabiting shallower water habitats showed lower genetic diversity with higher levels of population subdivision, suggesting processes resulting from intraspecific differences in habitat preference, climatic histories and/or larval ecologies have subdivided populations of shallow water triplefin species.
Molecular Phylogeny and Phylogeography of the Australian Freshwater Fish Genus Galaxiella, with an Emphasis on Dwarf
The authors' combined phylogeny and dating analysis point to an origin for the genus dating to the early Cenozoic, with three of the four species originating during the Oligocene-Miocene, and each Galaxiella species showed high levels of genetic divergences.
Contrasting Genetic Structure and Diversity of Galaxias maculatus (Jenyns, 1848) Along the Chilean Coast: Stock Identification for Fishery Management.
The results support the existence of different stock units for G. maculatus and this information should be integrated in future management strategies and aquaculture programs for this species.
Mitochondrial DNA reveals monophyly of New Zealand’s Gobiomorphus (Teleostei: Eleotridae) amongst a morphological complex
Monophyly of the genus Gobiomorphus and all seven New Zealand species was strongly supported, and among the non-diadromous forms, species morphology contrasts with the molecular data suggesting a recent evolutionary history driven by ecological selection.
Molecular phylogeny of the Aplodactylidae (Perciformes: Cirrhitoidea), a group of Southern Hemisphere marine fishes
Phylogenetic relationships indicate that the Aplodactylidae originated in the approximate region of Australia and New Zealand, with the majority of radiation occurring prior to this family achieving representation in South America.
Low genetic differentiation between two geographically separated populations of demersal gadiform fishes in the Southern Hemisphere.
Current/recent dispersal may be an important common factor for determining the distribution of demersal fishes in the Southern Hemisphere and low but significant genetic differentiation observed requires treating the two populations of the economically important grenadiers and southern blue whiting, respectively, as different stocks for proper resource management.


Intraspecific phylogeography of the Cape galaxias from South Africa: evidence from mitochondrial DNA sequences
It is suggested that another detailed revision is required to determine whether these divergent populations of the Cape galaxias Galaxias zebratus represent a single species or a species complex.
Molecular Phylogeny and Biogeography of the Tasmanian and New Zealand Mudfishes (Salmoniformes : Galaxiidae)
The phylogenetic affinities of the diadromous Tasmanian mudfish, Galaxias cleaveri, have long been problematic. Some systematists have suggested that this species is closely related to the
Molecular zoogeography of freshwater fishes in the southeastern United States.
Results exemplify the positive role that intraspecific genetic analyses may play in historical zoogeographic reconstruction and point out the potential inadequacies of any interpretations of population genetic structure that fail to consider the influences of history in shaping that structure.
Galaxias maculatus : An explanation of its biogeography
The populations examined appear to be part of the same gene pool, indicating that gene flow via dispersal through the sea occurs today, and it is unlikely that South American and Australasian populations would be conspecific if they have exchanged no migrants since the break-up of Gondwana at the end of the Mesozoic.
Isozyme analysis of Galaxias species (Teleostei: Galaxiidae) from the Taieri River, South Island, New Zealand: a species complex revealed
It is proposed that the genetic structuring and subsequent speciation of this group has been promoted by the absence of the marine juvenile phase that is found in five other members of the genus native to New Zealand.
A molecular analysis of relationships and biogeography within a species complex of Holarctic fish (genus Osmerus)
P Phenetic and parsimony analyses of the sequence divergence estimates and of sequence polymorphisms suggested that the north Pacific/Arctic form and the northwestern Atlantic form shared a common ancestor more recently than either has with the north‐eastern Atlantic form, thus supporting the hypothesis that the species complex has arisen from two independent Pacific‐Atlantic divergences probably beginning during the mid‐Pliocene.
Mitochondrial DNA analysis confirms the existence of two glacial races of rainbow smelt Osmerus mordax and their reproductive isolation in the St Lawrence River estuary (Quebec, Canada)
The sympatric occurrence in the estuary of anadromous populations alternatively dominated by one mtDNA clade or the other indicated that reproductive isolation mechanisms between the two races developed within this contact zone, the first evidence of secondary intergradation among distinct races of aquatic organisms in an estuarine environment.

Mitochondrial DNA Phylogeography and Subspecies Issues in the Monotypic Freshwater Turtle Sternotherus odoratus
The pronounced phylogeographic population structure in S. odoratus effectively falsifies prior hypotheses that extensive dispersal and gene flow account for the morphometric conservatism among geographic populations and raises broader issues concerning the significance of subspecies designations in testudine systematics.
Genetic and morphological differences between populations of the western minnow, Galaxias occidentalis, from two river systems in south-western Australia
Allozyme electrophoresis was used to examine patterns of genetic differentiation in the western minnow, Galaxias occidentalis, from the North Dandalup and Canning Rivers in south-westem Australia and a significant deficit of heterozygotes and a non-random association of alleles among loci was observed in these two samples.
