FIGURE 7. Result of regression analyses and the normality test of two linear characters, aLML and MRH. A, Fitting data (aLML vs MRH; n = 138) to a von Bertalanffy growth model. B, aLML values distribution histogram with a gap marking between two subsamples. C, Visual combination of the result of four separate regression analyses: line d1, von Bertalanffy (n = 138); d2 line, bivariate linear regression (BLR; S. tundrensis, n = 20); d3 line, BLR (PtU, n = 56); d4 line, BLR (Serov, n = 45). D, The regression line parameters, d1–d4. Key: a, line of Gaussian distribution; b, gap, detected by the W-test; c, an overlapping zone, calculated by the predicted values (μ ± 2σ); PtU (1063), re-defined specimen (from S. araneus to S. tundrensis).
