摘要: 脊椎动物性别决定模式一直是进化生物学领域的热点问题,它对个体发育和自然种群性比组成都具有深刻的影响。性别决定模式根据主要成因可分为基因依赖型性别决定(GSD)和环境依赖型性别决定(ESD)2大类,其中温度依赖型性别决定(TSD)又是ESD中的主要性别决定模式。多数羊膜类脊椎动物具有稳定的GSD模式,而爬行动物的性别决定模式则丰富多样,即使是亲缘关系很近的物种也具有不同的模式。研究者们以爬行动物为模型动物开展了许多关于脊椎动物性别决定方面的工作。本文综述了近年来爬行动物TSD的最新研究进展,回顾了温度和性激素对TSD爬行类动物的影响及其进化适应意义,以及气候变化与TSD爬行类的关系,并提出了今后爬行动物TSD研究的重点。

Abstract: The sex determination mechanisms (SDMs) of vertebrate is one of the hotspots in the studies of evolutionary biology, being of significance in both ontogeny and sex ratio of natural population. According to the main causal agents of sex determination, the SDMs can be categorized into genotypic sex determination (GSD) and environmental sex determination (ESD), and the temperature-dependent sex determination (TSD) is the primary SDM in ESD. Most amniote vertebrates have a stable GSD mechanism, while reptiles have various kinds of SDMs, and even, the closely related species might have different mechanisms of SDMs. With reptiles as model systems, the researchers have made many studies on the SDMs of vertebrate. Here, we summarized the latest research on the TSD of reptiles, with the focus on the combined effects of temperature and hormone, the adaptive significance of TSD evolution, and the potential impacts of climate change on the TSD reptiles. Efforts were made to point out the priority in further TSD studies in reptiles.
