Biogeography of the southern cool-temperate galaxioid fishes: evidence from metazoan macroparasite faunas
This study seeks evidence for coevolution between the galaxioid fish families, Galaxiidae and Retropinnidae, and their macroparasites as a means of adding to our understanding of the biogeography of the fish families. Location
These families are characteristic southern cool-temperate elements in the fish faunas of Australia, New Zealand and southern South America and some southern/sub-Antarctic islands. Methods
The analysis is based on a review of the literature. Results
Analysis showed that in each area fish species have parasites that are representative of the general fish parasite faunas of that area, rather than those characteristic of, or specific to, either these galaxioid families or the genera and species that they contain. In many instances the parasites also infect exotic fish species introduced into each area. Main conclusions
There is little evidence that parasite faunas have coevolved with the fish hosts. Parasite data therefore provide little support for a vicariance biogeography of galaxioid fishes in the southern cool-temperate region. Also, the data do not conflict with dispersal hypotheses for that biogeography.
