Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA MURIDAE

Scientific Name: Melomys talaudium
Species Authority: (Thomas, 1921)
Common Name(s):
English Long-tailed Talaud Melomys
Taxonomic Notes: Morphologically similar to M. leucogaster (Menzies 1996). Originally 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).

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(ii,iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Helgen, K. & Aplin, K.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
Listed as Endangered as it has a range of around 1,000 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.

Geographic Range [top]

Range Description: This species is found only on Karakeland and Salebabu in the Talaud Islands, Indonesia (Helgen 2003).

Population [top]

Population: It is known only from a handful of specimens, and there is no information available on current population status.
Population Trend: Decreasing

Habitat and Ecology [top]

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).
Systems: Terrestrial

Threats [top]

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 [top]

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.
