FIGURE 4 in Incipient speciation in allopatric Etheostoma rupestre (Percidae: Etheostomatinae) lineages, with the description of three new subspecies
FIGURE 4. First and second principal components for meristic data for the three subspecies of Etheostoma rupestre. Variable loadings for each principle component are as follows: PC1—lateral line scales: -0.43, scales above lateral line: -0.47, scales below lateral line: -0.47, caudal peduncle scales: -0.44, dorsal spines: -0.21, dorsal rays: -0.05, nape squamation: 0.21, belly squamation: 0.30; PC2—lateral line scales: 0.12, scales above the lateral line: 0.20, scales below the lateral line: 0.14, caudal peduncle scales: 0.14, dorsal spines: 0.21, dorsal rays: 0.19, nape squamation: 0.71, belly squamation: 0.58.
FIGURE 2 in Incipient speciation in allopatric Etheostoma rupestre (Percidae: Etheostomatinae) lineages, with the description of three new subspecies
FIGURE 2. Locations of museum material examined that possessed lat/long coordinates. Dark grey background shading indicates the boundaries of the Mobile Basin and colored shading indicates geographic ranges of each subspecies within the Mobile Basin to which Etheostoma rupestre is endemic. Populations delimited as E. r. rupestre in the current study but for which some taxonomic uncertainty remains are also indicated.
FIGURE 1. Cytochrome-b in Incipient speciation in allopatric Etheostoma rupestre (Percidae: Etheostomatinae) lineages, with the description of three new subspecies
FIGURE 1. Cytochrome-b phylogeny (modified from Janosik et al. [2023] with permission from Springer Nature Publishing Company; subject to associated copyright policy) displaying the three allopatric lineages of Etheostoma rupestre. Bayesian posterior probabilities are displayed on the nodes. EU296687.1 is a GenBank individual from Piller et al. (2008). Individuals that did not sort into the three major clades may indicate incomplete lineage sorting or recent gene exchange between lineages.

Figure 7 in A highly polymorphic South American collared lizard (Tropiduridae: Tropidurus) reveals that open-dry refugia from South-western Amazonia staged allopatric speciation
Figure 7. Scatterplots of PC1 and PC2 generated by the principal component analyses and LD1 and LD2 generated by the linear discriminant analyses performed on meristic variables of males (A, C) and females (B, D). See Table 8 for corresponding summary statistics.
Figure 5 in A highly polymorphic South American collared lizard (Tropiduridae: Tropidurus) reveals that open-dry refugia from South-western Amazonia staged allopatric speciation
Figure 5. Illustration of the chromatic polymorphism and frequency of the five flank (F1–F5) and ventral body (V1–V5) morphs identified across populations of Tropidurus from savannah enclaves from Rondônia (Tropidurus madeiramamore). Each shade indicates a different chromatic morph, and each chart represents a different locality, with values for males (top) and females (bottom) shown separately. See Figure 1 for details on the geographical location and characteristics of each site: (1) Cacoal; (2) Santa Cruz da Serra; (3) Ariquemes; (4) Itapuã do Oeste; (5) FLONA Jamari; (6) EFMM; (7) UNIR; (8) Jaci-Paraná; and (9) Guajará-Mirim.
Figure 2 in A highly polymorphic South American collared lizard (Tropiduridae: Tropidurus) reveals that open-dry refugia from South-western Amazonia staged allopatric speciation
Figure 2. Phylogenetic tree of Tropiduridae based on nuclear plus mitochondrial data combined, showing the distant relationship between the Tropidurus from savannah enclaves from Rondônia (Tropidurus madeiramamore) and Tropidurus oreadicus. Non-parametric bootstrap values (1000 replicates) are shown associated with branches. Dashed lines indicate branches whose lengths were altered for graphical purposes. In the lower left section of the figure, the lateral heads of the holotypes of T. madeiramamore (live specimen, MZUSP 107155) and T. oreadicus (preserved specimen, MZUSP 9465) are shown to illustrate the discrepancy in size between their lateral neck mite pockets. This diagnostic character distinguishes the species unambiguously. Scale bar: 1 cm.
