In the 1870s, an intense quest revealed to scientists that pituri, an important Aboriginal commodity, was sourced from the plant Duboisia hopwoodii?a shrub named after a well-known colonist. But it was Aboriginal people and white explorer-pastoralists from the Mulligan River region in far western Queensland who provided the samples and alerted scientists to the important chemical properties of pituri. Subsequently, there was a proposal to change the name of the plant to Duboisia pituri. Whom should the plant have been named after, the colonist or the Aborigine?

Potorous Tridactylus

Rat-kangaroos have not coped well with the impact of European settlement in Australia. Of the 11 species present in 1788, two are extinct, two are either mostly or totally restricted to offshore islands and the range of all other species has been much reduced. Habitat alienation, altered fire regimes, grazing, predation by introduced carnivores, competition from rabbits and timber harvesting have variously taken their toll on these little-seen animals. The rat-kangaroo was one of the first Australian marsupials to be seen alive in Europe. Collected close to the settlement at Sydney Cove, a pair of them were exhibited in London in 1789. These animals were called by the local Aboriginal people 'Pot-o-roo', and by the European settlers, 'Kangooroo rat'. They were the Long-nosed Potoroo, Potorous tridactylus, the first of what we now call 'Rat-kangaroos' to be discovered. Bettongs, Potoroos and the Musky Rat-kangaroo provides an extraordinary glimpse into the secretive lives of these unusual marsupials. It also reveals little-known facts about the critical functional role these creatures play in maintaining the forest and woodland habitats in which they live.

Major Study

The Australian bustard is Australia's heaviest flying bird. It is an icon of the Australian outback where it is more commonly known as the bush or plains turkey. It is also culturally and spiritually significant to Aboriginal people, who prize it as a favourite bush tucker. This book provides the first complete overview of the biology of the Australian bustard, based on the first major study of the species. The author explores the bustard's ecology and behaviour, its drastic decline since European settlement, and the conservation issues affecting it and its environment. Colour photographs of juvenile and adult birds complement the text as well as showcase particular behaviours, such as the spectacular display routines of males when mating. Australian Bustard is the perfect book for natural history enthusiasts.

The Status

Abstract The extensive massacre of Aboriginal people in the Roper River region of the Northern Territory resulted in drastic language disruption. The settling of remnants of many language groups at the Roper River mission led to the creation of Kriol. Now, after five generations, it is the primary language of many thousands of people. Bible translation and bilingual education programs have been highly significant in raising the status of Kriol. Its future seems assured, particularly as it increasingly becomes associated with Aboriginal identity and political aspirations.

Four new species and one new subspecies of Arctiinae (Lepidoptera: Erebidae) are described. Aphyle niedmandi sp. nov., Evius ocassus sp. nov., Paranerita maculata sandeepani ssp. nov., Paranerita kotolnuki sp. nov. and Baritius flexuosus sp. nov. were collected in the Tambopata River region, Madre de Dios (Peru), as part of a Citizen Science Project, in mutual collaboration between the Natural History Museum (Lima–Peru) and Rainforest Expeditions. External morphological descriptions, morphology of male genitalia, and geographic distributions in Peru are given for all taxa as well as their barcoding.

And Chemical Properties

Several years ago an opportunity was given to one of us to examine poisoned arrows and the poison used in smearing them, of the Wa Nyika tribe of East Africa. While the pharmacological action of this poison was found to have a close resemblance to that of Strophanthus seeds, its physical and chemical properties enabled the conclusions to be drawn that the poison was not made from these seeds, but was chiefly composed of an extract prepared from a wood. These conclusions have been confirmed by the examination of further specimens of the Wa Nyika arrow-poison, and of the wood from which it is prepared. Specimens of the Wa Gyriama and of the Wa Kamba arrow-poisons and of the wood from which they are prepared have also been examined.

Abstract Metals often are classified as “noble” or “base”—characterizing their reduction potential as one of the most important chemical properties. We show that metals are only as noble as allowed by their environment, i.e. this is a relative term, and the “frame of reference” simply is the solvent in which the redox system is present. We prove that silver is a prime example for a noble metal that forfeits its noble character in the simple ionic liquid HMIM Br (1-hexyl-3-methylimidazolium bromide) as an example for such a solvent.
