From: Digit ratio in the common toad Bufo bufo: the effects of reduced fingers and of age dependency
Panel a: relationship between size (SVL, snout-vent length) of the common toad Bufo bufo and right forelimb 2D:4D (variant II) for each sex (for each individual, SVL was centered around the mean size for its sex); Panel b: relationship between age (determined using skeletochronology) and right forelimb 2D:4D (variant II) for each sex; Panel c: relationship between age and left hindlimb 2D:4D for each sex; Panel d: relationship between age and left hindlimb 3D:4D for each sex. Age results were obtained from the second dataset containing only individuals from site 2 (N = 99; individuals after 3, 4, 5, 6, 7, or 8 hibernations. For more details, see Fig. S1)
