在西高止山脉-斯里兰卡生物多样性热点地区，大陆和岛屿之间明显的生物亲缘关系被解释为最近低海平面时期频繁迁徙的结果。我们表明，使用分子生物学的两个无脊椎动物和四个脊椎动物群体，这些地区之间的生物交换已远远超过迄今为止的假设。尽管在过去的50万年里有几次延长的陆地连接，斯里兰卡仍然保持着与印度大陆截然不同的动物群。未来的保护计划，为次大陆应考虑到这种模式的地方特有在最好的规模，他们可能会发生。
The apparent biotic affinities between the mainland and the island in the Western Ghats-Sri Lanka biodiversity hotspot have been interpreted as the result of frequent migrations during recent periods of low sea level. We show, using molecular phylogenies of two invertebrate and four vertebrate groups, that biotic interchange between these areas has been much more limited than hitherto assumed. Despite several extended periods of land connection during the past 500,000 years, Sri Lanka has maintained a fauna that is largely distinct from that of the Indian mainland. Future conservation programs for the subcontinent should take into account such patterns of local endemism at the finest scale at which they may occur.
