Hi all, I'm new to the field and I would like to ask you a few
suggestions. I have compiled a morphological character/species matrix
including only discrete characters (presence/absence and multistate),
which I would like to analyze in a phylogenetic framework. Since in my
group of interest there is a species complex, I would like to use the
relevant bits of the morphological matrix to visualize the species
complex in morpho. space. I have in mind a PCA kind of plot showing the
different entities of the species complex with circles. Some will
overlap completely, others less. I would also like to find out which are
the most useful morphological characters for teasing the entities of the
species complex apart. I have read some articles on traditional
morphometrics and it appears that what I intend to do comes closer to a
Discriminant Analysis, but I learn that this is mainly (only?) for
continuous characters. Do you have any suggestions (also regarding the
software that I could use)?
Cheers
gabriele
