Olfaction is an important sensory modality for mate recognition in many mammal species. Odorants provide information about the health status, genotype, dominance status and/or reproductive status. How and when odor profiles change during sexual maturation is, however often unclear, particularly in free-ranging mammals. Here, we investigated whether the wing sac odorant of male greater sac-winge...

To test a proposition central to J. Belsky, L. Steinberg, and P. Draper's (1991) evolutionary theory of socialization-that pubertal maturation plays a role in linking early rearing experience with adolescent sexual risk taking (i.e., frequency of sexual behavior) and, perhaps, other risk taking (e.g., alcohol, drugs, delinquency)-the authors subjected longitudinal data on 433 White, 62 Black, a...

Abstract Over the past decades, Atlantic salmon ( Salmo salar, Salmonidae) has emerged as a model system for sexual maturation research, owing to high diversity of life history strategies, knowledge trait genetic architecture, and their economic value. The aim this synthesis is summarize current state concerning in salmon, outline gaps, provide roadmap future work. We knowledge: 1) takes place ...

References 107 Abstract Genetic and environmental factors may interact to control sex determination in fishes. A common pattern of initial female differentiation and subsequentmale transformation before maturation in non-hermaphroditic fishes and after maturation in sequentially hermaphroditic fishes has suggested that changes in developmental timing may be responsible for the evolution of vari...

Chalcalburnus mossulensis from the cyprinidae family is one of the indigenous fish in Gheshlagh Lake of Kordestan, Iran. Ligula intestinalis is one of the infective parasites among various species of fish and causes gonads atrophy. In this study, after detection of species and age of samples, the effects of this parasite on gonads tissues and sexual maturation of Chalcalburnus mossulensis were ...
