I am conducting a morphometric study involving the wings of the Asian citrus psyllid. In my data collection, I was unable to capture the wing images in exactly the same way due to later processing that had to be conducted on the specimen. The images obtained wing shape and measurement information and differences were found between the two groups. I am concerned because of the different methods used that this may not be a real difference, but rather an artifact of my data collection practices.
My analysis consists of two-dimensional data only and it involved wings mounted on a slide compared to wings adjusted so that they came into the plane of measurement. The differences between the measurements were thus that wings were attached to the body versus dissected and on a slide. One solution that I have considered is to obtain a sample of ACP and do the ACP first with wings attached and then with wings dissected and see if there are any differences. If there are no differences then, I can assume that the wings measurements are approximately accurate. Does this sound reasonable? I am using MorphoJ for geometric morphometrics and PAST for Traditional Morphometrics.
