Multivariate Generalized Least Squares (GLS) approach to test for a relationship between SSD and sex differences in bridging propensity. a) Partial regression plots between female bridging propensity (fbp) in the y axis and female body mass (fmass) in the x axis, controlled for male body mass (mmass) and male bridging propensity (mbp). b) carapace width is used instead of body mass; fcw, female carapace width; mcw, male carapace width. All variables were log-transformed (see text for more details).
