FIGURE 1 in VARSEDIG: an algorithm for morphometric characters selection and statistical validation in morphological taxonomy
FIGURE 1. Application of VARSEDIG to compare Moenkhausia dichroura and M. oligolepis with the overlap method and the argument minimum=TRUE, as default options of VARSEDIG. (A) Density plot with the overlap of the variable that best discriminates the two species, in this case variable M26. (B) Scatterplot of the polar coordinates obtained for both species using variables M26 and M11. The ellipses show the levels of significance to the 0.5 (inner ellipse) and 0.95 (outer ellipse) of each of the regions. (C) Bivariate randomisation test. The x-axis corresponds to the X polar coordinates and the y-axis corresponds to Y polar coordinates. Kernel density is estimated to indicate the contours of the distribution of randomized values (blue line). The two marginal histograms correspond to the univariate tests on each axis for which the p-values (one-sided tests) are computed. The figure shows the individual (red point) with a higher probability of belonging to Moenkhausia oligolepis among all included individuals identified as M. dichroura. (D) As in figure C, this shows the individual (red point) with a higher probability of belonging to M. dichroura among all individuals identified as M. oligolepis.
