硬骨鱼是脊椎动物性别可塑性的“冠军”。一些物种有两种雄性生殖形态，具有不同的行为、躯体、神经、内分泌和生活史特征。在这里，我们考虑了这些物种的性可塑性的社会和神经调节的最新研究，重点是两种神经肽，促性腺激素释放激素（GnRH）和精氨酸血管催产素（AVT，哺乳动物精氨酸血管加压素的硬骨类似物）。本综述的主要前提是，大脑中GnRH和AVT表达的表型变化可以协调导致性状态或生殖中重要的形态特异性显示行为表达变化的事件。版权所有(C) 2001 S. Karger AG，巴塞尔
Teleost fishes are the 'champions' of sexual plasticity among vertebrates. Several species have two male reproductive morphs with distinct suites of behavioral, somatic, neuronal, endocrinological, and life history traits. Here, we consider recent studies of the social and neural modulation of sexual plasticity for such species with a focus on two neuropeptides, gonadotropin releasing hormone (GnRH) and arginine vasotocin (AVT, teleostean analogue of mammalian arginine vasopressin). The major premise of this review is that phenotypic changes in GnRH and AVT expression in the brain can orchestrate events leading to changes in either sexual status or the expression of morph specific display behaviors important in reproduction.
