TL;DR: The distribution data of Galaxiidae in South America is updated, relating extant distribution to physiological and reproductive characteristics of the species, latitude, temperature, and post-glacial opportunities for colonization.

TL;DR: The role of vicariance mechanisms (mountain building and drainage changes during the Pleistocene) have played in producing phylogeographical structure within and among South American fish species of the temperate perch family Percichthyidae as discussed by the authors.

TL;DR: The status of the freshwater fish fauna of Patagonia, an assemblage with 26 native species, comprising fishes of Gondwanan origin, marine dispersants, and oceanic elements of local origin, was reviewed in this paper.

TL;DR: A significant decline in the relative abundances of salmonids and an increase of P. trucha are found from twenty years back up to the present: basic concepts needed not only in future research but also in management design for Patagonian fish populations.

TL;DR: It is concluded that fish introduction in Laguna Blanca led to a complex trophic cascade effect producing deleterious effects on the amphibian and bird populations.
