- More endemic birds occur in regions with stable climate, more . . .
Background Geographical distribution of endemic species and its multiple scale drivers are an important topic in biodiversity conservation, because these species are especially vulnerable to climate change and habitat degradation, and therefore have high conservation priority Here, for the first time, we simultaneously linked glacial-interglacial climate change, contemporary climate, plant
