Brief SummaryRead full entry
BiologyThis small rodent uses branches, stones and grass to construct nests that may reach an amazing one metre in height and over a metre in diameter (2). Interestingly, on Franklin Island they do not usually build self standing nests, and instead construct smaller structures around shrubs (2). Tunnels lead from the perimeter of the nest to the centre, which is lined with soft vegetation (3). Nests usually contain up to four individuals, consisting of an adult female and her two to three young (4), and aggressive behaviour is shown towards unfamiliar members (2). Unlike many Australian rodents this species is active at night, when it forages in the dark for leaves and fruits of succulent plants (2) (3). Pairs establish strong bonds and breeding occurs throughout the year. The gestation period lasts 44 days, after which one to three young are born (3). Offspring become independent after two months, and once mature are capable of producing two to three litters per year (3).
