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.
