Fig. 6. Intrasexual size dimorphisms of the chelipeds and pleons during the breeding and non-breeding seasons of the porcellanid crab Petrolisthes japonicus, collected from April 2008 to March 2009. Intrasexual size dimorphism was represented by the coefficient estimate of the explanatory variable, including the Season (lnCW × Season), in the log-transformed allometric growth equation model: lny ~ lnCW + lnCW × Season, where CW is carapace width, y is the measurement for another body part (cheliped propodus length (PrL) and width (PrW), and pleon width (PlW)), and Season is the breeding season (May to September) or non-breeding season (October to April). The coefficient estimate of lnCW × Season was the output for the breeding season, representing the change in the response variable relative to the baseline category (non-breeding season) (Table S4), and thus also representing the degree of difference in the allometric growth coefficient between the breeding season and the non-breeding season. Vertical lines indicate standard errors. The dotted bar indicates an estimate that was not significantly different between the breeding season and non-breeding season.
