位于苏门答腊岛西南部的四个明打威岛长期以来与巽他兰群岛的其余部分隔绝，导致了高度的地方性。研究了巽他兰群岛明打威群岛151个物种的分布，并对可能导致不同生物地理格局的各种过程进行了评估。位置东南亚，特别是明打威群岛和附近的大片陆地（苏门答腊，爪哇，婆罗洲和马来西亚半岛）。方法对明打威群岛的43种哺乳动物、92种爬行动物和16种两栖动物与巽他兰群岛附近4个大陆的动物区系进行了形态学比较和最新的分子系统发育分析。这些比较产生了姊妹分类群，它们被用来模拟四个巽他兰大陆在几种情况下的物种缺失数据，以研究物种缺失模式是如何产生的。结果与我们的预期相反，明打威的一些物种在邻近的苏门答腊岛上没有最近的亲戚，而是在更远的婆罗洲、爪哇或马来西亚半岛上。在哺乳动物方面，明打威和婆罗洲物种之间的相似性大于明打威和苏门答腊物种之间的相似性。我们的结论是，这种关系代表了在更新世期间在苏门答腊灭绝的物种在历史上分布于整个巽他兰的痕迹。对爬行动物和两栖动物而言，观察到的物种缺失模式与缺失率随着陆地隔离而增加的情景下的模拟模式大致相似，而对哺乳动物而言，我们观察到爪哇和苏门答腊的缺失物种多于预期，婆罗洲的缺失物种少于预期。主要结论苏门答腊的灭绝可能有两个原因：更新世气候和植被的变化和多巴超级火山喷发的环境影响。
AimThe four Mentawai islands, south‐west of Sumatra, have long been isolated from the remainder of Sundaland, resulting in a high level of endemism. We examined the distribution of 151 species of the Mentawai Islands in Sundaland and assessed various processes that may have resulted in the various biogeographical patterns.LocationSoutheast Asia, particularly the Mentawai Islands and nearby large landmasses (Sumatra, Java, Borneo and Peninsular Malaysia).MethodsWe compared the faunal composition of the Mentawai Islands for selected taxa (43 mammals, 92 reptiles and 16 amphibians) with that of the four nearby large landmasses of Sundaland using morphological comparisons and the most recent molecular phylogenetic analyses available in the literature. These comparisons yielded sister taxa, which were used to simulate species absence data for the four Sundaland landmasses under several scenarios to investigate how patterns of species absence could have arisen.ResultsIn contrast to our expectations, several Mentawai species did not have their closest relatives on neighbouring Sumatra, but rather on the more distant Borneo, Java or Peninsular Malaysia. For mammals, the similarity between species from Mentawai and Borneo was greater than that observed between species from Mentawai and Sumatra. We conclude that the relationships represent traces of species historically distributed throughout Sundaland that became extinct in Sumatra during the Pleistocene. For reptiles and amphibians the observed pattern of species absences generally resembled the simulated pattern expected under the scenario of absence rates increasing with landmass isolation, whereas for mammals we observed more species than expected missing from Java and Sumatra, and fewer than expected from Borneo.Main conclusionsThe potential extinctions on Sumatra probably had two causes: changes of climate and vegetation during the Pleistocene and environmental impacts from the Toba supervolcanic eruption.
