Histological and Molecular Characterisation of Gonadal Phenotypes Confirms Diandry in a Protogynous Wrasse Open
Sequentially hermaphroditic fish begin life as one sex and change to another at some stage of their lifecycle. To date, the majority of research into this fascinating process has focused on sex change in sexually mature fish. The current s…

The use of gonadotropin-releasing hormone analogue (GnRHa) to induce reproduction in captive yellowbelly flounder (Rhombosolea leporina) Open
Recent interest in aquaculture of the endemic New Zealand yellowbelly flounder (YBF) has highlighted the need to develop hatchery technology for this species. However, knowledge of the reproductive biology of YBF is limited, and controlled…

Behavioural and neural correlates of social hierarchy formation in a sex-changing fish Open
Social hierarchies in sex-changing fish determine which fish will change sex, yet the complexities of hierarchy formation at the neurobehavioural level are still being unravelled. Here, we investigate the formation of social hierarchies wi…

Induced oocyte maturation in yellowbelly flounder Open
Recent interest in developing aquaculture of the endemic New Zealand yellowbelly flounder (YBF) has highlighted the need to develop captive breeding technology for this species. A pilot investigation of induced reproduction was conducted, …

Social hierarchies in sex-changing fish determine which fish will change sex, yet the complexities of hierarchy formation at the neurobehavioral level are still being unraveled. Here, we investigate the formation of social hierarchies with…

Neuroanatomy of a sex changing fish: the New Zealand spotty wrasse ( <i>Notolabrus celidotus</i> ) brain atlas Open
For most vertebrates, sexual fate is genetically determined and remains fixed throughout life. However, for some teleost fishes sex is more plastic. Significant progress has been made in characterising the cellular and molecular processes …

Effects of cortisol on female-to-male sex change in a wrasse Open
Sex change occurs as a usual part of the life cycle for many teleost fish and the modifications involved (behavioural, gonadal, morphological) are well studied. However, the mechanism that transduces environmental cues into the molecular c…

Conservation and diversity in expression of candidate genes regulating socially-induced female-male sex change in wrasses Open
Fishes exhibit remarkably diverse, and plastic, patterns of sexual development, most striking of which is sequential hermaphroditism, where individuals readily reverse sex in adulthood. How this stunning example of phenotypic plasticity is…

Bending Genders: The Biology of Natural Sex Change in Fish Open
Sexual fate is no longer seen as an irreversible deterministic switch set during early embryonic development but as an ongoing battle for primacy between male and female developmental trajectories. That sexual fate is not final and must be…
