Mountain biodiversity is of great importance to biogeography and ecology. However, it is unclear what ecological and evolutionary processes best explain the generation and maintenance of its high levels of species diversity. In this study, we determined which of six common hypotheses (e.g., climate hypotheses, habitat heterogeneity hypothesis and island biogeography theory) best explain global patterns of species diversity in . We found that diversity patterns were most strongly explained by proxies of island biogeography theory (i.e., mountain area) and habitat heterogeneity (i.e., elevation range). When we examined other relationships important to island biogeography theory, we found that the planimetric area and the volume of mountains were positively correlated with the diversity, whereas the 'mountains-to-mainland' distance was negatively correlated with diversity and shared species. Our findings demonstrate that diversity can be explained by island biogeography theory and habitat heterogeneity, and mountains can be regarded as islands which supported island biogeography theory.
山地生物多样性对生物地理学和生态学极为重要。然而，尚不清楚何种生态和进化过程能最好地解释其高度物种多样性的产生和维持。在本研究中，我们确定了六个常见假说（如气候假说、栖息地异质性假说和岛屿生物地理学理论）中哪一个最能解释[此处原文缺失具体研究对象]的全球物种多样性模式。我们发现，物种多样性模式最有力地由岛屿生物地理学理论的代理指标（即山区面积）和栖息地异质性（即海拔范围）所解释。当我们研究对岛屿生物地理学理论重要的其他关系时，我们发现山地的平面面积和体积与物种多样性呈正相关，而“山地与大陆”的距离与物种多样性和共享物种呈负相关。我们的研究结果表明，[此处原文缺失具体研究对象]的物种多样性可以由岛屿生物地理学理论和栖息地异质性来解释，并且山地可被视为支持岛屿生物地理学理论的岛屿。
