Figure 16.1 Cladograms depicting relationships among the families of extant salamanders. Left: Phylogenetic reconstruction based on combined morphological and molecular data for 32 amphibians, 28 of which were salamanders (Wiens et al., 2005). Right: Phylogenetic reconstruction based on 3747 unambiguously aligned base pairs of one mitochondrial and four nuclear genes sampled from 171 amphibians, 27 of which were salamanders (Roelants et al., 2007). Both cladograms redrawn from originals for uniformity, and only salamander families are included.
