Fishes of southern South America: a story driven by temperature [PDF]

Fish Physiology and Biochemistry, 2008
The latitudinal extension of southern South America imposes a thermal gradient that affects the structure of marine and freshwater fish assemblages and the biology of the species through direct exposure to the temperature gradients or by means of a web of historical and ecological relationships. We have reviewed biological and ecological data of marine
