Figure 3.

Sex differences in bridging propensity (SDI_bp) vs. SSD (SDI_SSD). SSD was measured as an SDI index either using body mass (a) or carapace width (b). Also an SDI index was calculated for sex differences in bridging propensity (see text for more details about how the SDI index is built). The plots show the linear relationship between SSD-a) SDI_mass; b) SDI_CW- and sex differences in bridging propensity (SDIbp). Points are independent contrasts.
