Sound production during courtship and spawning of Oreochromis mossambicus: male–female and male–male interactions
The role of sound production of the Mozambique tilapia Oreochromis mossambicus in agonistic and mating interactions observed during hierarchy formation and in established groups was examined. Only territorial males produced sounds, during male–female and male–male courtship interactions and during pit-related activities (e.g. dig, hover and still in the nest). Sound production rate was positive...
متن کاملThe outcome of male–male encounters affects subsequent sound production during courtship in the cichlid fish Oreochromis mossambicus
Social status in lek-breeding species is highly correlated with mating success. Reproductive failure of subordinates may be caused either by direct aggression by dominant males or by induced physiological changes. We hypothesized that recent social status (winning or losing an encounter with another male) affects the production of courtship sounds in male Mozambique tilapia, Oreochromis mossamb...
متن کاملContact Chemoreceptors Mediate Male-Male Repulsion and Male-Female Attraction during Drosophila Courtship
The elaborate courtship ritual of Drosophila males is dictated by neural circuitry established by the transcription factor Fruitless and triggered by sex-specific sensory cues. Deciphering the role of different stimuli in driving courtship behavior has been limited by the inability to selectively target appropriate sensory classes. Here, we identify two ion channel genes belonging to the degene...

15 صفحه اولDifferences between Male and Female Growth and Sexual Maturation in Tilapia (oreochromis Mossambicus)
In tilapia, growth during critical periods of the life cycle varies at different ages of development and is influenced by sexual maturation. The mechanisms controlling gametogenesis and how growth affects this process are poorly understood. This study indicates that tilapia exhibit a sexually dimorphic growth pattern in which males grow faster and bigger than females. During critical periods of...
