岛屿为隔离和物种形成提供了机会。印澳群岛（IAA）的许多陆地都是海洋岛屿，发现者事件物种形成预计将是这些岛屿上飞翔分类群的主要形式。我们研究了狐蝠的地理历史，一组有许多特有物种和岛屿的偏好，以验证这一假设，并推断该组的地理起源。澳大拉西亚，印度-澳大利亚群岛，马达加斯加，太平洋岛屿狐蝠（狐蝠科）为了推断狐蝠的地理历史，我们从10个标记中测序了6169 bp的遗传数据，并使用BEAST重建了34个目前公认的狐蝠物种和亚种的多位点物种树，其中3个是Acerodon外类群，随后使用BioGeoBEARS中实现的模型估计了祖先区域。物种水平的分辨率偶尔低，因为缓慢的分子进化速度和/或最近的分歧。然而，更古老的分歧得到了更有力的支持，并允许推断该组的进化历史。该属在Wallacea中从其与Acerodon的共同祖先中分化出来; Wallacea的创始人事件物种形成是一个常见的推论。密克罗尼西亚和西印度洋的狐蝠物种也被推断为创始人事件物种形成的结果。在IAA地区和岛屿之间的扩散促进了整个IAA和其他地区的狐蝠的多样化。分散在狐蝠是远远高于大多数其他的volant类群研究到目前为止，突出了岛屿间的运动在这一大分支的大型蝙蝠的地理历史的重要性。
Islands provide opportunities for isolation and speciation. Many landmasses in the Indo-Australian Archipelago (IAA) are oceanic islands, and founder-event speciation is expected to be the predominant form of speciation of volant taxa on these islands. We studied the biogeographic history of flying foxes, a group with many endemic species and a predilection for islands, to test this hypothesis and infer the biogeographic origin of the group. Australasia, Indo-Australian Archipelago, Madagascar, Pacific Islands Pteropus (Pteropodidae) To infer the biogeographic history of Pteropus, we sequenced up to 6169 bp of genetic data from 10 markers and reconstructed a multilocus species tree of 34 currently recognized Pteropus species and subspecies with 3 Acerodon outgroups using BEAST and subsequently estimated ancestral areas using models implemented in BioGeoBEARS. Species-level resolution was occasionally low because of slow rates of molecular evolution and/or recent divergences. Older divergences, however, were more strongly supported and allow the evolutionary history of the group to be inferred. The genus diverged in Wallacea from its common ancestor with Acerodon; founder-event speciation out of Wallacea was a common inference. Pteropus species in Micronesia and the western Indian Ocean were also inferred to result from founder-event speciation. Dispersal between regions of the IAA and the islands found therein fostered diversification of Pteropus throughout the IAA and beyond. Dispersal in Pteropus is far higher than in most other volant taxa studied to date, highlighting the importance of inter-island movement in the biogeographic history of this large clade of large bats.
