The development of the numeric taxonomy, and at the same time of the cladistic methodologies has substantially deviated the study of the morphologic plasticity from the genecological methods. Genotype-environment correlations are studied in this work by analyzing the morphologic plasticity of individues and thus considering this morphological phenomenon as a genotype effect. A multivariate methodology designated as morphoecology is used to characterize the morphologic plasticity of individues of the genus Dianthus L. in the Iberian Peninsula. The morphologic plasticity is then correlated with environmental factors in order to determine the effect of the latter on the phenotype expression.
