Table 3 Results of logarithmized models describing the allometric relationships between gonopod length (GL, males) and abdomen width (AW, females) on carapace width (mm) in juveniles and adults, for Alagoas and Ceará crabs

  1. N is the number of specimens. The slope (b) is the inclination of the regression line that determines the type of allometric growth of the gonopod length and abdomen width in relation to carapace width: isometric growth (=), positive allometric (+), and negative allometric growth (−). R 2 is the coefficient of determination. SE is the standard error of the slope
