Climate change has been considered to pose critical threats for wildlife. During the past decade, species distribution models were widely used to assess the effects of climate change on the distribution of species' suitable habitats. Among all the vertebrates, amphibians are most vulnerable to climate change. This is especially true for salamanders, which possess some specific traits such as cutaneous respiration and low vagility. The Wushan salamander () is a threatened and protected salamander in China, with its wild population decreasing continuously. The main objective of this study was to predict the distribution of suitable habitat for using the ENMeval parameter-optimized MaxEnt model under current and future climate conditions. Our results showed that precipitation, cloud density, vegetation type, and ultraviolet radiation were the main environmental factors affecting the distribution of . Currently, the suitable habitats for are mainly concentrated in the Daba Mountains, including northeastern Chongqing and western Hubei Provinces. Under the future climate conditions, the area of suitable habitats increased, which mainly occurred in central Guizhou Province. This study provided important information for the conservation of . Future studies can incorporate more species distribution models to better understand the effects of climate change on the distribution of .
气候变化被认为对野生动物构成重大威胁。在过去十年中,物种分布模型被广泛用于评估气候变化对物种适宜栖息地分布的影响。在所有脊椎动物中,两栖动物最易受到气候变化的影响。对于蝾螈来说尤其如此,它们具有一些特定特征,如皮肤呼吸和低移动性。巫山蝾螈()是中国一种受威胁和保护的蝾螈,其野生种群数量持续减少。本研究的主要目的是在当前和未来气候条件下,使用ENMeval参数优化的最大熵模型预测的适宜栖息地分布。我们的结果表明,降水、云密度、植被类型和紫外线辐射是影响分布的主要环境因素。目前,的适宜栖息地主要集中在大巴山,包括重庆东北部和湖北西部省份。在未来气候条件下,适宜栖息地面积增加,主要发生在贵州省中部。本研究为的保护提供了重要信息。未来的研究可以纳入更多的物种分布模型,以更好地了解气候变化对分布的影响。
