Phenotypic integration: relationship between the sexual dimorphism index (SDI) of body size (SDISVL, snout-vent length) and digit ratio (SDIdigit ratio) between three study sites marked as squares (panels: a, b) and four age cohorts marked as dots (panels: c, d). The digit ratio used was as follows: Panels a, c – right forelimb 2D:4D (variant II); Panels b, d – left hindlimb 3D:4D. Age results were obtained from the second dataset containing only individuals from site 2
