Abstract:
... The Caribbean King crab Mithrax spinosissimus is the largest brachyuran found in the western Atlantic and it supports subsistence and small commercial fisheries throughout the Caribbean and Gulf of Mexico. Because of its short larval duration and rapid growth, M. spinosissimus is considered a good candidate for aquaculture. Our study documents for the first time the size at sexual maturity, sexual ...

Subject:
Cichlidae; allometry; body size; discriminant analysis; evolution; females; fish; gender differences; gonads; interspecific variation; males; sex determination analysis; sexual dimorphism; Lake Malawi; Malawi
Abstract:
... The African cichlid fishes show great diversity in mating displays and reproductive strategies, yet species differences in genital morphology have been little studied. Observational notes have described broad sex differences in external genital shape between males and females, but these differences have not been quantified. We examined three aspects of genital morphology (relative anogenital dista ...

Apodemus speciosus; allometry; discriminant analysis; females; males; mice; multivariate analysis; ontogeny; sexual dimorphism; skull; standard deviation
Abstract:
... Static skull morphological variation in the large Japanese field mouse (Apodemus speciosus) was analyzed using different indices of variability. Multivariate analysis of variance revealed sexual dimorphism in cranium and mandible sizes, among a total of 89 skulls (45 males and 44 females). The coefficient of variation (CV), standard deviation (SD), and residuals of the standard deviation (RSD) wer ...

Abstract:
... Information on allometry, condition indices (CIs), and biometric traits (BTs) of marine bivalves are necessary for determining the growth pattern and the size at which harvest can be intensified to maximize production in aquaculture. These parameters of marine bivalves are largely regulated by the complex interactive effects of various ecological and physiological factors. Therefore, the present s ...
