摘要

水蚤根据环境条件在无性繁殖和有性繁殖策略之间切换。对于有性生殖，不利的环境信号诱导雄性的产生和减数分裂卵的形成。这两种表型的诱导都强烈依赖于节肢动物内分泌因子幼崽激素（JH）。本文综述了水蚤生殖策略改变调控机制的研究现状，重点介绍了近几十年来与JH信号相关的研究进展。进一步探讨了水蚤复杂生命周期和环境适应系统的进化机制和演化过程。

Environmentally Dependent Alteration of Reproductive Strategies and Juvenile Hormone Signaling in Daphnia (Crustacea: Cladocera).

Daphnia switches between asexual and sexual reproductive strategies, depending on environmental conditions. For sexual reproduction, unfavorable environmental signals induce production of males and formation of meiotic eggs. Induction of both these phenotypes is strongly dependent upon the arthropod endocrine factor juvenile hormone (JH). This review presents the current state of research on regulatory mechanisms of reproductive strategy alteration in Daphnia, focusing on studies related to JH signaling conducted during the past several decades. Additionally, it discusses what is needed in future research to fully understand these mechanisms and evolution of complicated life cycle and environmental adaptation systems in Daphnia.

期刊介绍： Zoological Science is published by the Zoological Society of Japan and devoted to publication of original articles, reviews and editorials that cover the broad field of zoology. The journal was founded in 1984 as a result of the consolidation of Zoological Magazine (1888–1983) and Annotationes Zoologicae Japonenses (1897–1983), the former official journals of the Zoological Society of Japan. Each annual volume consists of six regular issues, one every two months.
