Description
Figure 7 Principal Component Analysis (PCA) of osteological differentiation among species of the Gloydius himalayanus complex. A. Scatterplot of the first two principal components (PC1 and PC2) based on osteological ratio traits. Points represent individual specimens, colour-coded by species (Figs 1, 2), and convex hulls (shaded polygons) indicate the overall spread of each taxon in morphospace. Dashed arrows are included only as visual guides to displaced labels and have no analytical meaning. Axis labels indicate the percentage of variance explained by each principal component; B. Geographic distribution of sampled populations included in the osteological analysis across Pakistan, India, and Nepal. The inset shows the regional context within Central and South Asia. The map was produced in QGIS 3.28.
