Functional diversity is an integrative approach to better understand biodiversity across space and time. In the present study, we investigated the spatiotemporal patterns (i.e., elevation and season) and environmental determinants of anuran functional diversity on Tianping Mountain, northwest Hunan, China. Specifically, 10 transects were established from low (300 m a.s.l.) to high (1 492 m a.s.l.) elevations, and anuran communities were sampled in spring, early summer, midsummer, and autumn in 2017. Four functional diversity indices were computed for each transect in each season using ecomorphological functional traits. Our results demonstrated that these indices had contrasting responses to increasing elevations. However, they did not differ significantly among seasons in terms of temporal patterns. Interestingly, the unique spatiotemporal functional diversity patterns were impacted by distinct environmental variables, such as leaf litter cover, water temperature, number of trees, and water conductivity.
功能多样性是一种综合方法，用于更好地理解生物多样性在时空上的分布。在本研究中，我们调查了中国湖南西北部天平山无尾两栖类功能多样性的时空格局（即海拔和季节）及其环境决定因素。具体而言，从低海拔（海拔300米）到高海拔（海拔1492米）设置了10条样带，并于2017年在春季、初夏、盛夏和秋季对无尾两栖类群落进行了采样。利用生态形态功能性状，计算了每个季节每条样带的四个功能多样性指数。我们的结果表明，这些指数对海拔升高的响应各不相同。然而，就时间格局而言，它们在不同季节之间没有显著差异。有趣的是，独特的时空功能多样性格局受到不同环境变量的影响，如落叶覆盖度、水温、树木数量和水电导率。
