Figure 3 in A phylogenetic analysis of the arachnid orders based on morphological characters
Figure 3. Consensus trees produced by parsimony analysis of neontological data constrained to produce relationships proposed in the recent literature. The constrained (target) node is indicated by a black dot and the taxa encompassed by the constraint are enclosed in a box. Numbers below each tree represent the number of minimal-length constrained trees, length of minimal-length trees, difference in the length of the unconstrained minimal-length tree and the constrained minimal-length tree, and percentage unconstrained bootstrap trees in which the target node was recovered, respectively. These trees indicate the effect on branch length imposed by specific hypotheses and impact of constraining target nodes on nontarget nodes.
Figure 6 in A phylogenetic analysis of the arachnid orders based on morphological characters
Figure 6. Results from analysis of the full data matrix. A, minimal-length topology. Numbers below internodes are bootstrap percentages/Bremer support values. B, parsimony tree produced by implied weights with k = 1. C, parsimony tree produced by implied weights with k = 2. Parsimony trees produced by implied weights with k = 3–6 are identical to topology C. For B and C, relationships within terminal clades are the same as those shown in A.
Figure 5 in A phylogenetic analysis of the arachnid orders based on morphological characters
Figure 5. Results from analysis of neontological data. A, minimal-length topology. Numbers below internodes are bootstrap percentages/Bremer support values. B, parsimony tree produced by implied weights with k = 1. C, parsimony tree produced by implied weights with k = 2. Parsimony trees produced by implied weights with k = 3–6 are identical to topology A. For B and C, relationships within terminal clades are the same as those shown in A.
Figure 4 in A phylogenetic analysis of the arachnid orders based on morphological characters
Figure 4. Consensus trees produced by parsimony analysis of the full data matrix constrained to produce relationships proposed in the recent literature. See legend to Figure 3 for details.
Figure 2 in A phylogenetic analysis of the arachnid orders based on morphological characters
Figure 2. Fully resolved phylogenetic hypotheses of extant euchelicerate groups proposed in the recent literature. Note the similarity in the topologies of the parsimony-based analyses by Shultz (1990), Wheeler & Hayashi (1998) and Giribet et al. (2002). The Giribet et al. topology is based on neontological data (morphology and molecules) and the original 'ROOT' may be an artefact from use of the highly divergent pycnogonids as an outgroup.
Figure 1 in A phylogenetic analysis of the arachnid orders based on morphological characters
Figure 1. Cladogram summarizing results from analysis of major euchelicerate lineages generated by parsimony analysis of 59 genera and 202 non-molecular characters. Only those relationships that were well supported by bootstrap analysis or consistently recovered in sensitivity analysis are depicted; deepest relationships within Arachnida are effectively unresolved.
