Fig. 1 in Phylogeography of the Neotropical catfish Pimelodus albicans (Siluriformes: Pimelodidae) from río de la Plata basin, South America, and conservation remarks
Fig. 1. Hypotheses of phylogenetic relationship among three Siluriformes families: Pimelodidae, Heptapteridae, Pseudopimelodidae. a- Cladogram presented by de Pinna (1998). b- Consensus tree among three most parsimonious topologies based on cyt b sequences modified from Hardman (2005). Numbers above nodes are posterior probabilities recovered by the Bayesian analysis for those clades common to both parsimony and likelihood topologies. Nodes with 0 failed to reject the null hypothesis of zero length, and are considered falsely resolved. c- Maximum parsimony analysis of rag1 and rag2 sequences showing likelihood bootstrap values and Bayesian posterior probabilities (as %) modified from Sullivan et al. (2006).
