Electric eels galore: microsatellite markers for population studies

Abstract Fourteen novel microsatellite loci are described and characterized in two species of electric eels, Electrophorus variiand E. voltaifrom floodplains and rivers of the Amazon rainforest. These loci are polymorphic, highly informative, and have the capacity to detect reliable levels of genetic diversity. Likewise, the high combined probability of paternity exclusion value and low combined probability of genetic identity value obtained demonstrate that the new set of loci displays suitability for paternity studies on electric eels. In addition, the cross-amplification of electric eel species implies that it may also be useful in the study of the closely related E. electricus, and to other Neotropical electric fishes (Gymnotiformes) species as tested herein.
