Variation in growth pattern between some secondary sexual characters in crabs (decapoda brachyura)
TLDR
Le croissance relative, chez les crabes, de trois caracteres sexuels secondaires -pinces, abdomen et premiers pleopodes - a fait l'objet d'observations.Abstract:
Le croissance relative, chez les crabes, de trois caracteres sexuels secondaires -pinces, abdomen et premiers pleopodes - a fait l'objet d'observations. Il existe de fortes variations specifiques dans le taux de croissance, mais on peut cependant distinguer un mode de croissance distinct pour chacun des trois caracteres consideres. Il y a des differences dans ce mode suivant les caracteres consideres et suivant le sexe, et la signification adaptative de ces variations est discutee.read more
