Some Applications of Geometric Morphometrics to Ostracoda
Case histories of the application of geometric and algebraic morphometrics to the study of shape variation in fossil and living Ostracoda are reviewed. Evidence for polymorphism in shape is presented for the luminescent species Vargula hilgendorfii from Japan. Divergence in valve shape as a function of time for the fossil (Oligocene) species Neobuntonia airella from southeastern Australia is demonstrated. Many of the geometrically obtained results for Vargula hilgendorfii could be duplicated by the multivariate analysis of distance measures.
