Descripción
The spinifex hopping mouse (Notomys alexis), also known as the tarkawara or tarrkawarra, occurs throughout the central and western Australian arid zones, occupying both spinifex-covered sand flats and stabilised sand dunes, and loamy mulga and melaleuca flats. The population fluctuates greatly: in normal years it is sparsely distributed and probably confined to sandy country; after rain the population explodes and spreads to other types of habitat for a time. They are mostly seen at night, bounding across open ground on their large hind feet, with tails extended and the body almost horizontal. As semi-fossorial, burrowing surface foragers, the tiny hopping mice spend a great deal of energy not just foraging for food, but also transporting it back to their burrows. In fact, it was found that the total energy spent on transporting food in relation to energy investment on burrows far outweighed any other similar type of species.
