Figure 1 in A new genus of Atlantic octocorals (Octocorallia: Gorgoniidae): systematics of gorgoniids with asymmetric sclerites

Figure 1. Phylogenetic hypothesis (maximum likelihood estimated phylogram) of Atlantic gorgoniids, modified from Aguilar and Sánchez (2007a, Figure 4A). The ''Undescribed octocoral'' refers to the new genus and species described below. Above node letters: A, support corresponding to values.90 in 100 bootstrap maximum likelihood replicates, 1000 bootstrap values in maximum parsimony together with values over 0.9 posterior probabilities of Bayesian inference; B, support corresponding to values.90 in 100 bootstrap maximum likelihood replicates but lesser values for maximum parsimony or Bayesian inference (,70 or 0.70, respectively); C, support corresponding to values,70 in 100 bootstrap maximum likelihood replicates but higher values for maximum parsimony or Bayesian inference (,90 or 0.90, respectively). Character mapping: grey bars, gorgoniids with scaphoid sclerites (Clade 1); open bars-dotted, gorgoniids with capstan-derived sclerites (Clade 2); grid bars, gorgoniids with asymmetrical spiny sclerites (Clade 3); black bars, gorgoniids with long and spiny spindles (Clade 4). Scale in substitutions per site. *Pinnigorgia and Muriceopsis are also supported by a complete compensatory base change in their RNA secondary structure, a rare evolutionary event (see Aguilar and Sánchez 2007a).
