Locations of sampling sites: 1-Ubolratana dam (URD), 2-Kaeng Lawa (KLW), 3-Kaeng Nam Ton (KNT) and 4-Huai Chorakhe Mak (HCM).
Schematic image of beardless barb Cyclocheilichthys apogon showing 32 truss-network measurements constructed from 14 anatomical landmarks.
Bivariate scatterplots of Cyclocheilichthys apogon individuals along PC1-PC2 and PC1-PC3 axes of principal component analysis (PCA) for testing morphological variations among populations.
Patterns of morphological variation derived from the first three principal components (PC1-PC3) of principal component analysis (PCA) and multiple-pairwise comparisons for testing morphological variabilities among populations of Cyclocheilichthys apogon.
Discrimination plot of Cyclocheilichthys apogon individuals along DF1-DF2 axes of discriminant function analysis (DFA) on truss-network variables showing three separated groupings of the samples according to their river drainages.
