Journal ArticleDOI
Crying wolf, crying foul, or crying shame: alien salmonids and a biodiversity crisis in the southern cool-temperate galaxioid fishes?
TL;DR: The galaxioid fishes are the dominant, most speciose group of freshwater fishes (with >50 species) in the lands of the cool southern hemisphere, with representatives in western and eastern Australia, Tasmania, New Caledonia, Lord Howe Island, New Zealand, the Chatham, Auckland and Campbell Islands, Patagonian South America.
Journal ArticleDOI
Molecular phylogenetics and biogeography of galaxiid fishes (Osteichthyes: Galaxiidae): dispersal, vicariance, and the position of Lepidogalaxias salamandroides.
TL;DR: 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.
Journal ArticleDOI
The galaxiid fishes of South America
TL;DR: The galaxiids are regarded as southern circumpolar elements in the South American freshwater fish fauna, distinct from the group of species of Amazonian derivation (trichomycterids, Nematogenys, Diplomystes, Cheirodon, etc.) and distinct also from oceanic derivatives, either recent (atherinids) or ancient (serranids).
Journal ArticleDOI
Variation in vertebral number in galaxiid fishes (Teleostei: Galaxiidae): A legacy of life history, latitude and length
TL;DR: Overall, vertebral count is influenced by a complex amalgam of fish size, life history, and environment, supported by correlation between vertebral counts and size of juveniles of diadromous species at return from the sea, suggesting selection for vertebral number during marine life.
Journal ArticleDOI
Phylogenetic placement of retropinnid fishes: data set incongruence can be reduced by using asymmetric character state transformation costs.

TL;DR: It is recommended that morphological systematists routinely implement a range of character transformation models to assess the sensitivity of their phylogenetic reconstructions, and it is proposed that a simple "equal transformation cost" parsimony analysis may be biologically unrealistic.
