Implications of gendered environmental knowledge in water allocation processes in central Australia

The existence of gendered knowledge has been identified as a significant feature of Indigenous Australian culture, and the importance of considering the implications of gendered environmental knowledge in collaborative cross-cultural natural resource management has been highlighted. There is a lack of case studies that demonstrate how Indigenous women's knowledge and laws can be provided for in resource management contexts. From collaborative research with Anmatyerr women in central Australia, we discuss the implications of gender bias in relation to gendered knowledge in natural and cultural resource management, with a specific focus on Anmatyerr women's involvement in providing inputs about the cultural values of water within water allocation planning processes. This research highlights Anmatyerr women's own perspectives of their roles in contemporary contexts and identifies the existence of cultural change and continuity in relation to rights and responsibilities around water.     

Do silica phytoliths really wear mammalian teeth?

There is considerable literature suggesting that silica (opal) phytoliths cause dental enamel microwear in mammals. Much of this literature cites a single study from 1959 as evidence that silica phytoliths are harder than mammalian tooth enamel and so have the potential to cause dental microwear. No other studies using similar methodology have actually confirmed whether phytoliths are harder than dental enamel.     

The Reformation of the Eyes: Apparitions and Optics in Sixteenth- and Seventeenth-Century Europe

Apparitions were the subject of fierce theological and philosophical debate in the period after the Reformation. But these controversies also raised issues fundamental to the nature and organization of human vision. They crossed and recrossed the boundaries between religion and the science and psychology of optics. Apparitions, after all, are things that appear, and spectres are things that are seen. Before they could mean anything to anyone they had to be correctly identified as phenomena. Their religious role, whether Protestant or Catholic, presupposed a perceptual judgement — essentially visual in character — about just what they were. During the early modern period this judgement — this visual identification — became vastly more complex and contentious than ever before, certainly much more so than in the case of medieval ghosts. The sceptics, natural magicians, and atheists turned apparitions into optical tricks played by nature or human artifice; the religious controversialists and demonologists thought that demons might also be responsible. This essay argues that the debate that ensued, irrespective of the confessional allegiances of the protagonists, was the occasion for some of the most sustained and sophisticated of the early modern arguments about truth and illusion in the visual world.     

Lapita subsistence strategies and food consumption patterns in the community of Teouma (Efate,Vanuatu)

The subsistence strategies of the Lapita populations (3100–2800 BP), the first colonisers of the pristine environments of the islands of Eastern Melanesia and Western Polynesia, have been a matter of ongoing debate for decades. Opinions have ranged between the two extremes of Lapita colonisers being either characterised as highly mobile foragers to fully horticultural communities. To further address the question, this paper presents stable carbon and nitrogen isotopic data obtained from analyses of human and animal collagen samples from the site of Teouma (Efate, Vanuatu) dated to between c. 3000–2500 BP. The isotopic signatures obtained from 28 samples (23 human and 5 animal), interpreted in combination with isotopic information from several coastal and insular environments, suggest a diet primarily made up of terrestrially derived animal protein with lesser contributions from vegetable produce and inshore marine species. Comparisons linking the isotopic data gleaned from the Teouma individuals and Lapita subsistence patterns reconstructed through archaeozoological and archaeobotanical remains support the hypothesis of a mixed economy, that included terrestrial foraging, inshore marine exploitation and a low level of food production for at least some of the earliest Lapita colonists in Vanuatu.     

Mitochondrial DNA from 3000-year old chickens at the Teouma site,Vanuatu

Chickens were part of the Lapita cultural complex, transported into and through the Pacific by prehistoric colonists; as such they can be used as a proxy for tracking prehistoric migration and interaction. The Lapita site of Teouma in Vanuatu is well known for the recovery of complete dentate stamped pots and a cemetery containing the largest collection of Lapita period skeletons ever found. Chicken bones recovered from these excavations provide the first ancient DNA sequences from any commensal organism directly associated with a Lapita context. The ancient mtDNA sequences obtained from two Teouma chicken bones are compared with previously published archaeologically derived ancient DNA sequences to extend our understanding of the spread of chickens in Pacific prehistory. The results also show that the haplogroup E signature was present in very early populations of chickens transported into Remote Oceania. This study also adds to the suite of available data relating to isotopic signatures for commensal animals during the early settlement of Vanuatu and may reveal a different diet for Teouma chickens than those from other early prehistoric assemblages in the Pacific.
