Dear morphometricians,
lately I've been working on intraspecific morphological variation of a
lizard species from Morocco and I've come to be concerned with a quite
old matter of morphometrics, i.e. size correction of linear biometric
variables. I'm familiar with the bibliography on the subject and with
the numerous scientific discussions and advances that went on for almost
three decades (1960-1990). However, after having examined the different
methods, I'm not sure which one would be the more adequate. I know the
best thing to do would be to apply geometric methods, but what do we do
in the case that geometric morphometrics cannot be applied (in my case
it's almost impossible to define landmarks and use GM for the entire
body of a lizard)?
I tend to think that the best method would be the algorithm described by
Rohlf & Bookstein 1987 (Syst. Zool., 36 (4): 356-367) and performed by
Norm MacLeod's BURNABY procedure. However, I would really appreciate the
more experienced members' opinion on the subject before going on with
the analysis. Do you think you could help me out with this?
Thank you in advance
Antigoni
