Speciation in Freshwater Fishes
The extraordinary species richness of teleost fishes has attracted much research on mechanisms and modes of speciation. We here review research on speciation in freshwater fish in light of speciation theory, and place this in a context of knowledge about broad-scale diversity patterns in freshwater fishes. We structure our review around the major axes of divergence during speciation in freshwat...

متن کاملCarcinogens and cancers in freshwater fishes.
Epizootics of neoplasms in freshwater fish species are considered in relation to circumstantial and experimental evidence that suggest that some epizootics of neoplasia of hepatocellular, cholangiocellular, epidermal, and oral epithelial origin may be causally related to contaminant exposure. Although there is concern for the safety of consuming fish affected with neoplasms, this concern may be...
متن کاملClimate and local abundance in freshwater fishes
Identifying factors regulating variation in numbers of individuals among populations across a species' distribution is a fundamental goal in ecology. A common prediction, often referred to as the abundant-centre hypothesis, suggests that abundance is highest near the centre of a species' range. However, because of the primary focus on the geographical position of a population, this framework pr...
