Sundaland 563074 224526453 2008-07-09T07:03:09Z Brilliant Pebble 6005690 /* Ecology */ wikilink Wallace line '''Sundaland''' is a [[biogeography|biogeographical]] region of [[Southeast Asia|Southeastern Asia]] that comprises the [[Malay Peninsula]] and the [[Malay Archipelago]] islands of [[Sumatra]], [[Java]], [[Borneo]], and surrounding smaller islands. The eastern boundary of Sundaland is the [[Wallace Line]], identified by [[Alfred Russel Wallace]], which marks the eastern boundary of the [[Asia]]'s land [[mammal]] fauna, and is the boundary of the [[Indomalaya]] and [[Australasia ecozone]]s. The islands east of the Wallace line are known as [[Wallacea]], and are considered part of Australasia. Some scholars like Oppenheimer locate the origin of the [[Austronesian languages]] in Sundaland and its upper regions.<ref>Oppenheimer 1999</ref> Genetic research reported in 2008 indicates that the islands which are the remnants of Sundaland were likely populated as early as 50,000 years ago, contrary to a previous hypothesis that they were populated as late as 10,000 years ago from Taiwan.<ref>http://www.eurekalert.org/pub_releases/2008-05/uol-nrf052308.php</ref> ==Ecology== The islands of Sundaland rest on Asia's shallow [[continental shelf]]. During the [[ice age]]s, sea levels were lower and all of Sundaland was an extension of the Asian continent. As a result, the islands of Sundaland are home to many Asian mammals, including [[monkey]]s, [[ape]]s, [[tiger]]s, [[tapir]]s, and [[rhinoceros]]. The [[Wallace Line]], which includes the [[Lombok Strait]] between Bali and [[Lombok]], and the [[Makassar Strait]] between [[Borneo]] and [[Sulawesi]], marks the end of the Asian continental shelf, and the islands of Wallacea are separated from Asia and from [[Australia]] and [[New Guinea]] by deep ocean. Botanists often include Sundaland, the adjacent [[Philippines]], [[Wallacea]] and [[New Guinea]] in a single [[Floristic province]] of [[Malesia]], based on similarities in their flora, which is predominantly of Asian origin. ==Ecoregions of Sundaland== [[Tropical and subtropical moist broadleaf forests]] *[[Borneo lowland rain forests]] ([[Borneo]]) *[[Borneo montane rain forests]] ([[Borneo]]) *[[Borneo peat swamp forests]] ([[Borneo]]) *[[Eastern Java-Bali montane rain forests]] ([[Bali]], [[Java (island)|Java]]) *[[Eastern Java-Bali rain forests]] ([[Bali]], [[Java (island)|Java]]) *[[Mentawai Islands rain forests]] ([[Mentawai Islands]]) *[[Peninsular Malaysian montane rain forests]] ([[Malay peninsula]]) *[[Peninsular Malaysian peat swamp forests]] ([[Malay peninsula]]) *[[Peninsular Malaysian rain forests]] ([[Anambas Islands]], [[Malay peninsula]]) *[[Southwest Borneo freshwater swamp forests]] ([[Borneo]]) *[[Sumatran freshwater swamp forests]] ([[Sumatra]]) *[[Sumatran lowland rain forests]] ([[Sumatra]], [[Nias]], [[Bangka Island]]) *[[Sumatran montane rain forests]] ([[Sumatra]]) *[[Sumatran peat swamp forests]] ([[Sumatra]]) *[[Sundaland heath forests]] ([[Indonesia]]) *[[Western Java montane rain forests]] ([[Java (island)|Java]]) *[[Western Java rain forests]] ([[Java (island)|Java]]) [[Tropical and subtropical coniferous forests]]<br> *[[Sumatran tropical pine forests]] ([[Sumatra]]) [[Montane grasslands and shrublands]]<br> *[[Kinabalu montane alpine meadows]] ([[Borneo]]) [[Mangroves]]<br> *[[Sunda Shelf mangroves]] ([[Borneo]], [[Sumatra]], [[Riau Islands]]) == Notes and references== {{reflist}} === Further reading === *[[Stephen Oppenheimer]].
