Fig. 75 in PHYLOGENETIC SYSTEMATICS OF DART-POISON FROGS AND THEIR RELATIVES (AMPHIBIA: ATHESPHATANURA: DENDROBATIDAE)
Fig. 75. Strict consensus of 25,872 most parsimonious trees of 46,520 steps: relationships among dendrobatids. Numbers above branches are Bremer support values. Numbers following terminal names are unique sample identifiers. Terminals without numbers or with alphanumeric identifiers (GenBank numbers) were not sequenced for the present study or Frost et al. (2006) and were taken from GenBank. Unidentified species taken from GenBank are labeled as originally published. Upper right inset shows entire cladogram and corresponding figure numbers, with present view in black.
