Morphometric scatter plot of the first two axes from a Detrended Correspondence Analysis (DCA) for 155 specimens (classification of 10 seagrass species) constrained by 21 quantitative variables (taxonomic characters). Intraspecific variance is shown by error bars (2SD). Bi-plot arrows represent the strength of the correlations among explanatory variables and the first two DCA axes. Numbers of ethnotaxa are shown in parentheses for each species of seagrass indicating the fine-scale ethno-classification of intraspecific variation.
