Phylogenetic Systematics, Biogeography, and Ecology of the Electric Fish Genus Brachyhypopomus (Ostariophysi: Gymnotiformes)
Fig 5
Bayesian inference phylogeny for Brachyhypopomus based on total evidence (cytb, rag2, and morphology).
Bayesian posterior probabilities shown by nodes (not shown for intraspecific relationships). Branch lengths proportional to substitutions per site. Terminal taxa are 87 individuals representing 28 species of Brachyhypopomus and 18 individuals representing 9 outgroup taxa. Branch lengths show substitutions per site. Branch lengths for Gymnotus and Sternopygus (represented with dashed lines) are reduced. See Table 3 for list of sequenced specimens. Terminal two letter codes refer to the drainage units described in ‘Geographic and ecological distributions’ (Materials and Methods).
