Item type: Item , Differential population history in the migratory catfishes <i>Brachyplatystoma flavicans</i> and <i>Pseudoplatystoma fasciatum</i>(Pimelodidae) from the Bolivian Amazon assessed with nuclear and mitochondrial DNA markers(Wiley, 2004) Jorge S. Coronel; Gregory E. Maes; S. C. Claus; Paul A. Van Damme; F.A.M. VolckaertThe catfishes Brachyplatystoma flavicans ( n = 49) and Pseudoplatystoma fasciatum ( n = 69) showed comparable low allozyme diversities ( H e = 0·012 and 0·009–0·028, respectively), but contrasting PCR‐RFLP restriction site mitochondrial DNA diversities (three haplotypes: π = 0·034–0·092 and five haplotypes: π = 0·001–0·023, respectively) in the Rio Ichilo and Beni (Bolivia). Genetic homogeneity between samples was high for B. flavicans and lower for P. fasciatum . Based on mitochondrial diversity, both species probably experienced a historic population reduction but at different time scales.
