Central pebble-mound mouse

Pseudomys johnsoni is a rodent of the genus Australian mice. This species was discovered in 1983 and 1985 scientifically described.

Features

Pseudomys johnsoni reaches a head-body length of 61-64 mm, a tail length of 76 mm to 95 mm, a Hinterfußlänge 17 to 18.5 mm, an ear length of 12 to 13 mm and a weight of 9-17 g The females have four abdominal teats. The top is light yellow brown to reddish brown with black hair protection. The underside is white. The tail is brown on top and white on the underside.

Occurrence

Pseudomys johnsoni comes in the Davenport and Murchison Ranges southeast of Tennant Creek and in the Mittiebah range on the near Alexandria Station in the Barkly Tableland in the Northern Territory. Other occurrences are known from the vicinity of the town of Mount Isa in Queensland and the Kimberley region in Western Australia.

Habitat

Pseudomys johnsoni inhabits a variety of habitats including open woodland, wooded valleys, dense bushy undergrowth and spinifex grasslands, which is dominated by species such as Plectrachne pungens and Triodia longiceps. This species prefers covered with pebbles ridges and plains with pebble hills and grasslands.

Way of life

Pseudomys johnsoni lives in a complex building system with a mound of pebbles next to the entrance, which is closed later. Lactating females were observed between August and September.

Status

In the past, this type has been considered to be rare. Studies of mice populations from Queensland, the Northern Territory and Western Australia showed, however, that Pseudomys johnsoni is more common than first thought. Although the habitat is fragmented, this type of inventory is widespread and stable. Therefore, it is " not at risk " by the IUCN in the category classified ( least concern ).

System

The taxon described by Darrell John Kitchener and William F. Humphreys 1986 Pseudomys laborifex, which was in 2005 listed in the standard work Mammal Species of the World as a valid way since 2007 is considered to be conspecific with Pseudomys johnsoni.
