Twenty-nine Australian land mammals have become extinct over the last 200 years, and 56 are currently facing extinction. These losses and potential losses represent over a third of the 315 species present…
More than a century after it was “lost”, the New Guinea big-eared bat has been discovered by Queensland researchers working in Papua New Guinea’s forests. The critically endangered bat was thought to be…
Picture a tropical rainforest, with thousands of species per hectare, and it’s quite easy to believe that up to three quarters of all plant and animal species are found in the tropics. But what makes the…
For 20 privileged Victorians, Benjamin Waterhouse Hawkins held a lavish New Year’s dinner party in 1853 inside a model of a dinosaur that was created for the Great Exhibition held two years earlier. Hawkins’s…

The Bramble Cay Melomys (Melomys rubicola) has one of the most unusual and precarious distributions of all Australian mammals. The melomys is restricted to an unstable 4-5 hectare coral cay in the eastern…
While people cheating on their partners is frowned upon in modern society, monogamy among mammals is something of an evolutionary puzzle. Some stick to one sexual partner for a lifetime. That is why the…
Australia’s small arid zone mammals have greatly suffered since European settlement. Some 11 species are extinct, and a further eight are listed as endangered or critically endangered. Their loss has been…
