Fig. 5. Monthly changes in the intersexual size dimorphisms of the chelipeds and pleons of the porcellanid crab Petrolisthes japonicus specimens, collected from April 2008 to March 2009. Intersexual size dimorphism was represented by the coefficient estimates for the explanatory variable, including the Sex (lnCW × Sex), in the log-transformed allometric growth equation model: lny ~ lnCW + lnCW × Sex, where CW is carapace width, y is the measurement for another body part (cheliped propodus length and width, and pleon width) and Sex is female or male. The coefficient estimate of lnCW × Sex was the output for males, representing changes in the response variable relative to the baseline category (female) (Tables S1–S3), and thus also representing the degree of difference in the allometric growth coefficient between males and females. Vertical lines indicate standard errors. The dotted bars indicates the estimates that were not significantly different between sexes. The data for October and November were pooled because of the small sample size in November.
