摘要/Abstract

摘要： 山地因独特的环境特征(地形地貌、气候和海拔等)和高度丰富的物种组成, 被认为是研究生物多样性分布格局及群落构建的热点地区。截至目前, 尚未有针对南北气候过渡带区域(如皖西大别山区)的山地两栖类物种多样性分布格局及其群落构建机制的报道。因此, 本文采用标准样线调查法, 在不同海拔梯度、生境类型和季节尺度上, 对皖西大别山地区无尾两栖动物的Alpha多样性与Beta多样性进行分析, 并结合气候、地形、生境及人为干扰等环境因素, 探讨其多样性格局及其影响因素。Alpha多样性的结果显示: 该区域共有无尾两栖动物6科12属18种且物种丰富度与海拔呈显著的负相关, 而Pielou均匀度指数则显示了相反的海拔变异规律; 此外, 该区域内无尾两栖动物的Shannon-Wiener多样性指数、Simpson优势度指数和Pielou均匀度指数在不同生境类型间表现出显著差异(农田生境高于其他生境), 其中Shannon-Wiener多样性指数还呈现出显著的季节性差异(夏季高于春季), 同时还发现年降水量是影响物种丰富度、Shannon-Wiener多样性指数和Simpson优势度指数的主要因素。Beta多样性的研究表明, Bray-Curtis指数和Sørensen指数表现出周转组分高于嵌套组分且年均温是影响Beta多样性指数及其周转组分的主要因素。本研究阐明了处于气候过渡带的皖西大别山地区两栖动物多样性格局及其影响因素, 为该区域生物多样性保护提供了数据支撑和理论依据。

Abstract

Aims: Mountain ecosystems, characterized by their distinctive environmental features and high biodiversity, provide an ideal model system for investigating biodiversity patterns and community assembly mechanisms. However, the Dabie Mountains, a climatically transitional zone between subtropical and warm temperate regions, remain understudied, particularly in terms of the spatial distribution and environmental drivers of amphibian diversity. To address this knowledge gap, this study aims to quantify the Alpha and Beta diversity patterns of anurans and identify the key environmental factors shaping their assembly along elevational gradients in this critical transitional region.

Method: This study employed the transect method to investigate the diversity and formation mechanisms of amphibians and reptiles within the Dabie Mountains of western Anhui Province, China.

Results: The results revealed that a total of 18 anuran species, belonging to 12 genera and 6 families, were recorded in the region. Species richness showed a significant negative correlation with elevation, whereas the Pielou index exhibited an opposite pattern along the elevational gradient. Moreover, the Shannon-Wiener, Simpson, and Pielou indices all varied significantly across habitat types, with higher values observed in farmland habitats than in others. The Shannon-Wiener index also displayed significant seasonal variation, being higher in summer than in spring. Annual precipitation was identified as the primary factor influencing species richness, Shannon-Wiener, and Simpson diversity indices. Beta diversity analysis based on both Bray-Curtis and Sørensen indices showed that the turnover component was greater than the nestedness component. Annual mean temperature was found to be the main factor affecting overall Beta diversity and its turnover component.

Conclusion: This study clarified the distribution pattern of amphibian diversity in the Dabie Mountains of western Anhui Province in the climate transition zone, revealed its influencing factors, and provided a theoretical basis and data support for biodiversity conservation in this region.
