Descripción
Sexual maturation in brachyurans has three different components: physiological, morphological, and functional. The second is visualized by examining changes in the morphometric relationships between some dimensions of the organs involved in mating and egg incubation, relative to a standard measure of size. Aiming to establish the size at morphological maturity for the Patagonian knobbed spider crab, Leurocyclus tuberculosus, a morphometric analysis was conducted on specimens sampled in the northern Patagonian gulfs (41°-43°S). Discontinuities were detected in ln transformed relationships of abdomen width on carapace width of females, and right chela length on carapace width of males. For females, estimated CWmorph50% (carapace width at which 50% of the individuals attains morphometric maturity) was 47.9 mm, and CW of the smallest ovigerous female observed in the samples was 42.7 mm. For males, a change in the growth rate of ln(ChL) relative to ln(CW) was detected at 48.9 mm CW.
La maturation sexuelle des brachyoures présente trois composantes différentes: physiologique, morphologique et fonctionnelle. On peut visualiser la seconde en regardant les changements dans les relations morphométriques entre certaines dimensions des organes impliqués dans la reproduction et l’incubation des oeufs par rapport à la mesure standard de la taille. Afin d’établir la taille à la maturité morphologique du crabe araignée noueux de Patagonie, Leurocyclus tuberculosus, une analyse morphométrique a été conduite sur des spécimens des golfes du nord de la Patagonie (41°- 43°S). Des discontinuités ont été détectées avec la transformation ln de la relation entre la largeur de l’abdomen (LA) sur la largeur du céphalothorax (LC) des femelles, et la longueur de la pince droite (LPD) sur la largeur du céphalothorax (LC) des mâles. Pour les femelles, la LCmorph50% estimée (largeur du céphalothorax pour laquelle 50% des individus atteignent la maturité morphométrique) a été 47,9 mm, et LC de la plus petite femelle ovigère observée dans les échantillons a été de 42,7 mm. Pour les mâles, un changement dans le taux de croissance de ln(LPD) en relation avec ln(LC) a été détecté à 48,9 mm du LC.
