Figure 6. Plot of the LDA on adults skulls’s symmetric shape coordinates
versus origins (left) and associated unrooted trees based respectively on
Mahalanobis distances (bottom-right) and Euclidian distances (top-right).
As PC1 contained information of allometry, we decided to perform the LDA on adult
specimens and thus to document shape variation in connection with the geographic origin
only.
Plot of the LDA skull symmetric shape coordinates versus origins (figure 6) separated the
four groups without any overlap. The topology of the plot (figure 6) suggested the existence
of three skulls shape patterns distributed on three extremes plot positions: turtles from AO
