|Scientific Name:||Melomys talaudium (Thomas, 1921)|
|Taxonomic Notes:||Melomys talaudium is morphologically similar to Melomys leucogaster (Menzies 1996). Originally it was described as a species, but Rümmler (1938) and Ellerman (1941) treated talaudium as a subspecies of M. leucogaster, Musser and Carleton (1993) listed it in the synonymy of that species, and Laurie and Hill (1954) arranged it as a subspecies of M. fulgens. Tate (1951) recognized talaudium as a distinct species as have Flannery (1995) and Menzies (1996). It is sympatric with M. caurinus, which has a shorter tail relative to head and body length, suggesting that M. caurinus may be terrestrial and M. talaudium arboreal (Flannery 1995, Thomas 1921).|
|Red List Category & Criteria:||Endangered B1ab(ii,iii) ver 3.1|
|Contributor(s):||Helgen, K. & Aplin, K.|
Melomys taladium is endemic to Indonesia. it is assessed as Endangered as it has an extent of occurrence (EOO) of approximately 1,577 km², is known from only two locations, and is believed to be undergoing continuing decline in its area of occupancy and the extent and quality of its habitat caused by deforestation.
|Previously published Red List assessments:|
|Range Description:||This species is found only on Karakeland and Salebabu in the Talaud Islands, Indonesia (Helgen 2003).|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is known only from a handful of specimens, and there is no information available on current population status.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is sympatric with Melomys caurinus. It is thought (due to tail size) that Melomys talaudium is arboreal, and M. caurinus is terrestrial, while other similarities point towards a common ancestor between these two species (Flannery 1995; Musser and Carleton 2005).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Major Threat(s):||The major threat is likely to be habitat loss as a result of deforestation due to logging. It may also be impacted by competition with introduced murids.|
|Conservation Actions:||It is present in Karakelang Utara dan Selatan Wildlife Reserve. There is a need for further survey work to determine the current population status of this species.|
|Errata reason:||This errata assessment has been created because the map was accidentally left out of the version published previously.|
