    A comparison of museum specimens has found that thylacines on mainland Australia were smaller than those that persisted into modern times in Tasmania, and significantly smaller than dingoes. The last known Tasmanian thylacine died in 1936. Measurements of the head size and thickness of limb bones of the semi-fossilised remains of thylacines and dingoes from caves in Western Australia have revealed that, on average, dingoes were larger than thylacines. “In particular, dingoes were almost twice as large as female thylacines, which were not much bigger than a fox,” says ecologist Dr Mike Letnic, an ARC Future Fellow in the UNSW...

  • Australian marsupials challenge gene theory

    Scientists studying the kangaroo genome have cast doubt on the credentials of a gene thought to be crucial to the process of inactivating one sex chromosome in women. The finding challenges a whole field of research that has developed around the XIST gene since its discovery in the early 1990s. Scientists had expected that the gene – which was thought to direct the switching off of a surplus X chromosome during embryonic development – would inform our understanding of how genes are controlled in normal development, and how control goes awry in genetic diseases such as cancer. The sophisticated genetic...

    Marsupials not colour-blind after all Catriona Purcell ABC Science Online Monday, 28 March 2005 This little creature, called a quokka, is helping to overturn long-standing beliefs about marsupial vision (Image: Catherine Arrese/Nature) Australian marsupials can see in full colour, new research has found, making them the only other mammals apart from primates to do so. A team led by Dr Catherine Arrese from the University of Western Australia in Perth reports its findings in the Proceedings of the Royal Society B, a journal of the UK's Royal Society. Most people think marsupials lack colour vision, says Arrese, but her team's...

    They are small and round and look like furry footballs - and they are being kicked to death by young Australians for "fun". The quokka, a species of miniature wallaby found only in Western Australia, has become the renewed target of a sadistic "sport" called quokka soccer. The quokka, a species of wallaby found only in Western Australia Since last Sunday, eight quokkas have been found dead on the seven mile-long island of Rottnest, apparently kicked or beaten to death. The animals were found on a cricket oval near Thomson Bay Settlement, one of the few villages on Rottnest, a...
