Hello everyone,
I’m currently running fluctuating asymmetry (FA) analyses through geometric morphometric methods on MorphoJ. On structures of matching symmetry (wings), I have been able to compare FA levels on all environmental conditions through a Procrustes ANOVA as expected. However, I would like to visualize *how* the variations in the environmental conditions change the wing shape as well. Because it is a structure of matching symmetry, there are no symmetric and asymmetric components, so I am unable to create a covariance matrix for a PCA or a CVA that include the asymmetric component. I have observed that publications about morphometrics for detecting disturbances on wings often mention shape changes in lieu of FA. Would it be correct to conduct a PCA based on the Procrustes coordinates as a way to observe shape changes in the dataset, not necessarily due to asymmetry? I would appreciate hearing your opinions about this, as I am new to the field and might have missed fundamental discussions or publications about FA on structures of matching symmetry. Many thanks in advance! Best, Helena. -- You received this message because you are subscribed to the Google Groups "Morphmet" group.
