Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA CHIROPTERA PTEROPODIDAE

Scientific Name: Dobsonia inermis
Species Authority: Andersen, 1909
Common Name(s):
English Solomons Bare-backed Fruit Bat, Solomon's Naked-backed Fruit Bat

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Hamilton, S. & Leary, T.
Reviewer(s): Lamoreux, J. (Global Mammal Assessment Team), Racey, P.A., Medellín, R. & Hutson, A.M. (Chiroptera Red List Authority)
Justification:
Listed as Least Concern in view of its relatively wide distribution, large population, tolerance of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Geographic Range [top]

Range Description: This species has been recorded from much of the Solomon Islands as well as neighbouring islands in Papua New Guinea (i.e., Bougainville and Buka, and possibly Nissan). Occurs from sea level to 1,000 m asl.
Countries:
Native:
Papua New Guinea; Solomon Islands

Population [top]

Population: This species is widespread and common. It is unknown to what extent there is genetic connectivity between island populations. It is unlikely, for instance, that there is any regular exchange of genes between the most distant population on Rennell Island and other islands in the Solomon Archipelago (S. Hamilton pers. comm.).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It roosts in medium-sized to large caves, although small numbers of individuals can be found in rock overhangs. It forages in disturbed areas and is less common in primary forests. Its closest relative, D. praedatrix, roosts in small colonies in the crowns of coconut trees (beneath old drooping fronds), and it is possible D. inermis may also utilize these roosting sites.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: Use information is based on the following statement in Bonaccorso (1998):
"This bat is hunted to obtain canine teeth used in bride-price necklaces on Buka Island. Such a necklace may have teeth from 200 pteropodid bats and fetch 300 kina when sold, but fortunately can be recycled to more than one bride in a family (S. Hamilton pers. comm.)."

Threats [top]

Major Threat(s): There are no major threats to this species. Whilst commonly observed in coastal areas, its dependence on caves for large breeding colonies makes it particularly susceptible to even low levels human disturbance and hunting.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures pertaining to this species.
