Univariate analysis of variance (ANOVA) results testing the effect of sex on several morphological traits of chela size for Cherax dispar

Variable	Sex F_1,66	P
Wrist depth	7.80	0.007^*
Maximum depth	7.96	0.006^*
Chela length	6.45	0.013
Propodus depth	4.69	0.034
Dactylus depth	5.11	0.027
Propodus length	8.52	0.0048^*
Dactylus length	7.73	0.007^*

Variable	Sex F_1,66	P
Wrist depth	7.80	0.007^*
Maximum depth	7.96	0.006^*
Chela length	6.45	0.013
Propodus depth	4.69	0.034
Dactylus depth	5.11	0.027
Propodus length	8.52	0.0048^*
Dactylus length	7.73	0.007^*

Analyses were performed on the relative size of morphological traits to chela size that was calculated as the first component derived from a principal component analysis (PCA) on the seven morphological variables (see Materials and methods for details). ^*Significant difference among groups taken after Bonferroni adjustment across the seven tests
