Geographic variation in the grey mullet: a geometric morphometric analysis using partial warp scores

Abstract

Multivariate examination of partial warps allowed the description of shape differences characterizing each of 10 populations of Mugil cephalus . Patterns of morphometric distances (overall, uniform and non‐uniform) among samples suggested that morphometry in part reflected the geographic origin of the samples. However, comparisons with allozymes and mtDNA provided no exhaustive evidence for a pure phylogenetic cause for the observed patterns of geographic Variation.
