Figure 9 in Dealing with allometry in linear and geometric morphometrics: a taxonomic case study in the Leporinus cylindriformis group (Characiformes: Anostomidae) with description of a new species from Suriname
Figure 9. Wireframe visualization of allometric shape change along the least squares regression line of Procrustes coordinates on log centroid size. Grey landmarks represent the average configuration amongst all specimens, whereas black landmarks represent the approximate extreme of variation (1.2 log centroid size units) in the direction of the smallest specimens, which have proportionally larger heads and eyes.

Figure 10 in Dealing with allometry in linear and geometric morphometrics: a taxonomic case study in the Leporinus cylindriformis group (Characiformes: Anostomidae) with description of a new species from Suriname
Figure 10. Wireframe visualization of variation along the allometrically corrected principal components one (PC1), two, and three from geometric morphometric analysis. Grey landmarks represent the configuration of the average specimen, black landmarks represent one approximate extreme of variation on that axis. The deformation on PC1 represents 0.07 units, that on PC2 represents 0.04 units, and that on PC3 represents 0.03 units. Percentages indicate the proportion of total variance amongst the Procrustes residuals explained by each axis.
Figure 7 in Dealing with allometry in linear and geometric morphometrics: a taxonomic case study in the Leporinus cylindriformis group (Characiformes: Anostomidae) with description of a new species from Suriname
Figure 7. Reduced major axis regression of principal component one (PC1) scores from traditional linear morphometrics on log standard length for species of Leporinus discussed in text. Trendline represents a universal regression that does not take species membership into account; tests for equivalence of slope and intercept as reported in Tables 2 and 3 estimate a separate regression line for each putative species.

Figure 11. Scatterplot of (A) principal components one and two and (B) principal components one and three from geometric morphometrics after allometric correction. Polygons represent convex hulls surrounding nominal species of Leporinus.
Figure 6 in Dealing with allometry in linear and geometric morphometrics: a taxonomic case study in the Leporinus cylindriformis group (Characiformes: Anostomidae) with description of a new species from Suriname
Figure 6. Scatterplot of principal component two (PC2) versus one from traditional linear morphometrics for species of Leporinus discussed in text. PC1 is an allometric vector describing size and shape variation, whereas PC2 is essentially size-free. Polygons indicate convex hulls.
