Origin of Bornean amphibian diversity viewed from lentic breeders

为了阐明婆罗洲两栖动物多样性的起源，对该岛及其邻近地区的双棱繁殖物种进行了研究。形态学、声学和分子系统发育分析表明，双栖两栖动物群的多样性远低于双栖两栖动物群，这可能是因为该岛被茂密的森林覆盖，缺乏合适的栖息地。一些棘蝗和微棘蝗是婆罗洲特有的物种，在苏门答腊和爪哇都有亲缘关系。人们认为，他们的祖先在大陆上分道扬镳，沿着另一条通往爪哇岛的路线进入该岛后，他们在岛上有很长的历史。为了充分了解婆罗洲两栖动物群的形成历史，需要对该岛周围地区进行进一步的研究。

In order to clarify the origin of amphibian diversity in Borneo, lentic-breeding species from this island and adjacent regions were studied. Morphological, acoustic, and molecular phylogenetic analyses revealed that the lentic-breeding amphibian fauna is much less diversified than the lotic-breeding one, probably because the paucity of suitable habitats on this island, which is covered by dense forests. Some rhacophorid and microhylid species are endemic to Borneo, and have their relatives from Sumatra to Java. They are thought to have very long histories on the island after their ancestors diverged on the continent and entered the island along with another route to Java. In order to fully understand formation history of amphibian fauna on Borneo requires further study in regions surrounding the island.
