Figure 2. Correlation between temporal changes in disparity and integration.

Figure 2

Spearmann’s rank correlation between level of morphological disparity and degree of morphological integration. (A) Generalized differences of morphological integration versus disparity for the PCoA-based approach (black circles; r = −0.118, P = 0.609) and the discrete character approach (open circles; r = −0.449, P = 0.042) when all characters are considered. (B) Generalized differences of morphological integration versus disparity for the PCoA-based approach (black circles; r = −0.340, P = 0.131) and the discrete character approach (open circles; r = 0.118, P = 0.609) when only taxonomically non-significant characters are considered (see text). In general, the amount of morphological disparity displayed by crinoids is not significantly correlated with the overall degree of integration among morphological traits.
