On the other hand, islands that were connected during the period of low sea level have highly similar faunas. All the islands that made up Greater Luzon Island share the same mammal fauna; there are no differences in the lowland fauna. Only the high elevations on Luzon have localized endemic species, where mossy forest habitats are isolated from one another (Rickart et al. 1998). The same is true, with only a few exceptions, throughout the rest of the Philippines and indonesia.
