Bettong
Bettongs, species of the genus ''Bettongia'', are potoroine marsupials once common in Australia. They are important ecosystem engineers displaced during the colonisation of the continent, and are vulnerable to threatening factors such as altered fire regimes, land clearing, pastoralism and introduced predatory species such as the fox and cat. Conservation status All species of the genus have been severely affected by ecological changes since the European settlement of Australia. Those that have not become extinct became largely confined to islands and protected reserves and are dependent on re-population programs. The diversity of the genus was poorly understood before their extirpation from the mainland, and new taxa have been identified in specimens newly discovered and already held in museum collections. In 2021 August, 40 Bettongs were released in different parts of South Australia; they were raised in captivity to increase their numbers. Taxonomy Four extant species ar ...

Bettongia Lesueur
The boodie (''Bettongia lesueur''), also known as the burrowing bettong or Lesueur's rat-kangaroo, is a small, furry, rat-like mammal native to Australia. Once common throughout the continent, it is now restricted to a few coastal islands. A member of the rat-kangaroo family (Potoroidae), it lives in burrows and is active at night when it forages for fungi, roots, and other plant matter. It is about the size of a rabbit and, like other marsupials, carries its young in a pouch. Before European settlement, it was the most common macropod in Australia (a group that includes kangaroos, wallabies, and other Australian mammals). Competition and predation by introduced rabbits, cats, and foxes, as well as habitat loss, pressured the population. It was declared a pest in the 1900s and was wiped out by the 1960s; however, the loss of the boodie and other ground-foraging animals has degraded soil quality. Populations persisted on three west coast islands (Bernier, Dorre, and Barrow), and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern Bettong
The northern bettong (''Bettongia tropica'') is a small, endangered, gerbil-like mammal native to forests in northeast Australia. A member of the rat-kangaroo family (Potoroidae), it moves by hopping and lives in burrows, feeding at night on roots and fungi. It is also a marsupial and carries its young in a pouch. The northern bettong is threatened by habitat loss, and is now restricted to a few small areas. Habitat The northern bettong is restricted to some areas of mixed open ''Eucalyptus'' woodlands and ''Allocasuarina'' forests bordering rainforests in far northeastern Queensland, Australia. Lifespan The typical bettong lives in the wild for about 4 to 6 years. This is a very short life span, but according to the Smithsonian's National Zoologist, they can, under proper care, live up to the age of 15 years. Behavior All species of the bettong are nocturnal. They carry nesting materials with their long tails and can be found in underground burrows that they escape to duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Bettong
The eastern bettong (''Bettongia gaimardi''), also known as the southern or Tasmanian bettong, is a small, hopping, rat-like mammal native to grassy forests of southeastern Australia and Tasmania. A member of the rat-kangaroo family (Potoroidae), it is active at night and feeds on fungi and plant roots. Like other marsupials, it carries its young in a pouch. The eastern bettong is under pressure by introduced predators and habitat loss. The subspecies on mainland Australia (''B. g. gaimardi'') is extinct, but populations of the Tasmanian subspecies (''B. g. cuniculus'') have been reintroduced there.Rose, R. (1997).

Bettongia Penicillata
The woylie or brush-tailed bettong (''Bettongia penicillata'') is a small, critically endangered, gerbil-like mammal native to forests and shrubland of Australia. A member of the rat-kangaroo family (Potoroidae), it moves by hopping and is active at night, digging for fungi to eat. It is also a marsupial and carries its young in a pouch. Once widespread, the woylie mostly died out from habitat loss and introduced predators such as foxes. It is currently restricted to two small areas in Western Australia. There are two subspecies: ''B. p. ogilbyi'' in the west, and the now-extinct ''B. p. penicillata'' in the southeast. Taxonomy A species was first described by J. E. Gray in 1837, based on the skin and skull of an adult male obtained by the Zoological Society of London, and placed with the British Museum of Natural History. The origin of the holotype has not been determined, but it is presumed to be New South Wales. The two subspecies recognised are: * ''Bettongia penicillat ...

Potoroinae
Potoroidae is a family of marsupials, small Australian animals known as bettongs, potoroos, and rat-kangaroos. All are rabbit-sized, brown, jumping marsupials and resemble a large rodent or a very small wallaby. Taxonomy The potoroids are smaller relatives of the kangaroos and wallabies, and may be ancestral to that group. In particular, the teeth show a simpler pattern than in the kangaroo family, with longer upper incisors, larger canines, and four cusps on the molars. However, both groups possess a wide diastema between the incisors and the cheek teeth, and the potoroids have a similar dental formula to their larger relatives: In most respects, however, the potoroids are similar to small wallabies. Their hind feet are elongated, and they move by hopping, although the adaptations are not as extreme as they are in true wallabies, and, like rabbits, they often use their fore limbs to move about at slower speeds. The potoroids are, like nearly all diprotodonts, herbivorous. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nullarbor Dwarf Bettong
The Nullarbor dwarf bettong, ''Bettongia pusilla'', was a potoroine marsupial that occurred in Australia. The animal is only known from skeletons found in caves of the Nullarbor Plain and is now classified as recently extinct. Taxonomy The Nullarbor dwarf bettong was a species of ''Bettongia'', a genus that includes still living species such as the northern bettong, belonging to the subfamily Potoroinae. The description was first published in 1997 by R. A. McNamara, using specimens collected on the Nullarbor Plain from the Koonalda and Weekes Caves. The holotype is part of a juvenile's right jaw, with some teeth absent, obtained at the Koonalda site. The author recognised an earlier description, misidentified as ''Caloprymnus campestris'' by Ernest Lundelius and William D. Turnbull in 1984, and the informal reference to an potoroid species. McNamara's paper on the new species details his diagnosis as arising independently, but gives credit for the discovery to earlier worker's ...
