Bettong


Bettong, species of the genus Bettongia, are potoroine marsupials once common in Australia. They are important ecological 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.

Taxonomy

Four extant species are recognised in the work Mammal Species of the World :
In addition, at least three extinct species are known:
The phylogeny of the genus has seen a grouping of 'brush-tailed' taxa allied within the genus Bettongia, and this includes the extant species Bettongia gaimardi, B. tropica and B. penicillata.
A conservative arrangement of modern and fossil taxa of Bettongia may be summarised as
The species Aepyprymnus rufescens is referred to as the rufous bettong, but this is not strictly correct.
