FIGURE 12 in On Putaoa, a new genus of the spider family Pimoidae (Araneae) from China, with a cladistic test of its monophyly and phylogenetic placement

FIGURE 12. One of the four minimal length trees of 205 steps that result from the analysis of the data matrix presented in Appendix 1 (CI = 0.52, RI = 0.75). Exclusion of the six parsimony uninformative characters decreases the tree length to 196 steps and the ensemble consistency index to 0.5. Ambiguous character changes are resolved under "Farris optimization." Closed circles represent non-homoplasious character changes. The two nodes that collapse in the strict consensus cladogram of the four most parsimonious trees are marked with a closed rectangle. Numbers at nodes indicate Bremer support / parsimony jackknife frequency (only those above 50% are reported). The basal trichotomy has been resolved according to the araneoid topology presented in Griswold et al. (1998); see text for additional details.

FIGURE 8 in New olenelline trilobites from the Northwest Territories, Canada, and the phylogenetic placement of Judomia absita Fritz, 1973

FIGURE 8. The strict consensus of three most parsimonious trees of length 198 steps produced from analysis of character data in Table 1 using PAUP 4.0 (Swofford 1998). Cladogram constructed using a heuristic search with a stepwise addition sequence and 100 random replications. Bremer, bootstrap (>50%), and jackknife (>50%) support values, respectively, are given on the tree. All characters were treated as unordered. The retention index is 0.54, and the consistency index (when uninformative characters are excluded) is 0.40. Total tree support (Bremer, 1994) is at least 0.07.
