Plot of canonical variates 1 and 2 from the discriminant function analysis showing the position of each male from the two genetic lineages (N = 116).

<p>Filled triangles represent the western lineage and unfilled circles represent the eastern lineage. Ellipses represent 95% confidence ellipses. CV1 differentiates individuals based primarily on tick load, spectral purity of the side and body condition (standardised canonical correlation between CV1 and tick load = 0.95; side spectral purity = −0.46; body condition = −0.36). CV 2 discriminates between populations primarily on ventral brightness (standardised correlation = 0.95).
