Abstract: Abstract The Neotropical region harbors > 7000 species of freshwater fish, many of them important as genetic resources for fisheries and aquaculture. The myriad aquatic environments of the Neotropics and the fish living there raise challenging scientific issues regarding local adaptation and the physiological mechanisms underlying locally adapted phenotypes. The current technologies for exploring genomes are boosting our knowledge about the genetic mechanisms underlying adaptation and how they operate at the physiological level. This chapter ex...
