华莱士线
冰河时期海平面与各种生物地理分界线

华莱士线是生物地理学中,区分东洋区和澳大拉西亚区的分界线。1854年到1862年英国动物地理学者亚尔佛德·罗素·华莱士在马来群岛研究岛屿上的动物时,注意到婆罗洲与苏拉威西岛、峇里岛和龙目岛之间,似乎有一条隐形的界线将两边的生物分开;界线以西接近东南亚的生物相,界线以东则接近新几内亚的生物相。华莱士注意到:峇里岛的鸟类与爪哇岛几乎相同,但在距峇里岛仅约30公里的龙目岛,却只有50%的鸟类相同。为纪念他的发现,科学界将划分这两区的界线称为华莱士线。

Wallace's Line delineates Australian and Southeast Asian fauna. The probable extent of land at the time of the last glacial maximum, when the sea level was more than 110 m lower than today, is shown in grey. The deep water of the Lombok Strait between Bali and Lombok formed a water barrier even when lower sea levels linked the now-separated islands and landmasses on either side.

冰河时期海平面与各种生物地理分界线

The Wallace Line or Wallace's Line is a faunal boundary line drawn in 1859 by the British naturalist Alfred Russel Wallace that separates the ecozones of Asia and Wallacea, a transitional zone between Asia and Australia. West of the line are found organisms related to Asiatic species; to the east, a mixture of species of Asian and Australian origin is present. Wallace noticed this clear division during his travels through the East Indies in the 19th century.
