Hello to all! I am currently involved in taxonomic research of some species of mammals, and for these projects intend to use 2d geometric morphometrics (along with other methods) to test for differences between pairs of putative species. As of yet, I have done a PCA of the Procrustes coordinates, and there seems to be some variation between species, but I would like to further test this with more accurate methods.
For that, I have seen some papers using a Procrustes Anova between pairs of putative species, but I am somewhat confused on how to proceed with these Anovas. Is it best that I use some correction on the results to account for the numerous comparisons, even if I do comparisons only between some of the possible pairings of species (i.e., species that share borders of their geographic distributions)? Finally, are there recommendations on how to proceed for those pairs of putative species for which the number of landmarks ends up being greater than the number of specimens? I would also greatly appreciate any bibliography recommendations regarding the usage of GM methods for taxonomy, as admittedly the statistics of these analyses is not my forte. Thanks in advance for any help. Best regards, Vítor -- You received this message because you are subscribed to the Google Groups "Morphmet" group.
