摘要

为了评估血浆皮质醇在雌雄同体、雌雄同体的变性鱼性别决定中的作用，研究了性未成熟的假小丑海葵鱼(Amphiprion ocellaris)，每3只饲养360天。观察皮质醇、雌二醇和11-酮睾酮的昼夜行为和血浆浓度的时间变化。假设实验组的社会等级在实验中期趋于稳定，但在实验开始和结束时，根据竞争行为频率的增加或减少而不稳定。血浆皮质醇浓度随着社会等级的不稳定而升高，雌二醇的变化趋势与皮质醇相反。这些结果表明，在雄性海葵鱼中，社会互动诱导的性别决定是由皮质醇介导的。社会等级的稳定性被认为对性别决定过程非常重要。

Influence of social stability on the sex determination process in false clown anemonefish (Amphiprion ocellaris)

ABSTRACT To evaluate the involvement of plasma cortisol in sex determination in hermaphrodite protandrous sex-changing fish, sexually immature false clown anemonefish (Amphiprion ocellaris) were kept in groups of 3 individuals for 360 days. Observations of time-course changes of diurnal behaviour and plasma concentrations of cortisol, oestradiol, and 11-ketotestosterone were evaluated. The social hierarchy of the experimental groups was assumed to become stable during the middle period of the experiment, but unstable at the beginning and at the end according to the increase or decrease in the frequencies of agonistic behaviours. The plasma concentration of cortisol increased as the social hierarchy became unstable and oestradiol showed the opposite trend to cortisol. These results suggest that in protandrous anemonefish sex determination induced by social interaction is mediated by cortisol. The stability of the social hierarchy is considered to be very important for the sex determination process.

期刊介绍： Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
