The Hawkesbury River of New South Wales, Australia is under increasing environmental stress. Pre-anthropogenic and current levels of heavy metal concentrations have been established for bed sediments between Windsor and Broken Bay. Sediment heavy metal concentrations in the main channel of the Hawkesbury River are close to background, but are substantially elevated in the headwaters of Berowra Creek, Cowan Creek and in southeast Pittwater. The Berowra Waters area and the upper catchment contribute both heavy metals and organochlorines/pesticides to the Berowra estuary. High contaminant levels above and below the Hornsby sewage treatment plant, and above and below the Calna Creek sewage treatment plant, make an assessment of the contribution by these plants difficult. Analyses of oyster tissue from the middle and lower reaches of the estuary indicate that heavy metal contaminants are entering the food chain.  相似文献

Acid sulphate soils form when iron pyrite oxidises to sulphuric acid on atmospheric exposure, lowering soil pH below 4. In the Richmond River estuary, northern New South Wales, flood mitigation, drainage works and floodplain excavations have augmented acid sulphate soil formation by increasing pyrite availability for oxidation. These engineering works have facilitated the transport of acidified water and have impeded recovery from tributary acidification. The increased frequency and duration of acidification are associated with elevated concentrations of inorganic monomeric aluminium and dissolved iron, and major iron hydroxide precipitation, with deleterious effects on exposed aquatic biota and habitat. Fish kills and an outbreak of epizootic ulcerative syndrome (EUS) have been recorded from acidified sites in the estuary.  相似文献

ABSTRACT Water is a resource that both unites and divides people in the Upper Hunter Valley of New South Wales, where many communities are facing the prospect of large‐scale open‐cut coalmining developments on productive mixed use land, or already live in proximity to mines and power stations. This article analyses conflicts over a proposed coal mine at Bickham in the Upper Hunter Valley, by contrasting the various protagonists' discourses of water scarcity, supply, and connectivity. It examines the ways in which the terms of opposition are narrowed to the arena of state and industry supported science and economic development, marginalising other cultural values and environmental ethics that are integral to opponents' discourses. Opponents have achieved some measure of success through contestation of the uncertain science of hydrological modelling, bolstered by the context of drought and increasing public acceptance of climate change science.  相似文献

A new genus and species of lungfish with toothplates, Adelargo schultzei, is described from the Hunter Siltstone (Devonian, Late Famennian) near Grenfell, New South Wales. Materials assigned to Adelargo schultzei gen. et sp. nov., include a portion of the left side of the skull comprising B, I (postparietal) and J (parietal) bones, pterygoid and prearticular toothplates, a parasphenoid with a long posterior stalk, vertebrae, ribs, anal fin supports and scales. Toothplates are similar to Dipterus, although morphology of the skull, parasphenoid and postcranial elements is more derived. Biogeographic relationships of the Grenfell fauna were based on the presence of the antiarch group Sinolepidoidei, also present on Asian terranes during the Late Devonian. A small number of lungfish scales have been described from Asian sinolepid localities of this age, but differ from those of Adelargo schultzei, and other faunal similarities between these areas appear limited. Paucity of eastern Australian Devonian taxa on the North and South China blocks implies that strong biogeographic relationships between eastern Australia and Euramerican localities during the Late Devonian were not the result of Asian migration routes, but the closer proximity of these areas.  相似文献

Festivals and carnivals are social‐cultural assemblages of human and non‐human entities. This paper investigates interactions between humans and animals by focusing on the Scone Racing Carnival, a key event in the Scone and Upper Hunter Horse Festival. This paper contributes to existing studies of non‐metropolitan festivals and animal–human relations by questioning how and why non‐humans are enrolled in these cultural events, and the impact this has on place identity. The central argument is that the relationship between humans and thoroughbred horses, in particular, has played a significant role in the creation of a distinctive landscape, a regional identity for the Upper Hunter region of New South Wales, and a local identity for Scone. In turn, the carnival has assisted in maintaining an ‘eque‐cultural’ identity through the marketing and annual public celebration of human–horse relationships.  相似文献

This article explores the emergence of popular music as a niche cultural industry, connected to economic and social transformations on the New South Wales Far North Coast (also known as the ‘Northern Rivers’ region). The various images of the New South Wales Far North Coast as a ‘lifestyle’ region, ‘alternative’ locale and coastal retreat have attracted a diverse mix of ex–urban professionals, unemployed persons, youth subcultures, backpacker tourists and retirees. Yet, despite population growth, the region continues to suffer unemployment rates among the highest in Australia. Against this backdrop, diverse popular music ‘scenes’ have emerged, constituting an industry with linkages to cultural production in Sydney, Melbourne and overseas. While the region’s unique cultural mix has been suggested as a key site of comparative advantage, future employment is likely to remain transient, insecure, and governed by industry–wide labour relations. This case study illustrates some of the complexities underpinning contemporary urban–regional change in Australia, and provides cautious assessment of the capacity of the cultural industries to reinvigorate rural economies.  相似文献

Coal seam gas and other unconventional gas industries have often struggled to develop a social licence to operate in surrounding communities, frequently resulting in the emergence of broad opposition coalitions and legal challenges. In this article, the authors explore the relational aspects of coal seam gas's space‐based setting with reference to Keith Halfacree's three‐fold model of rural space. Applying this model to coal seam gas development in New South Wales' Hunter Valley, we argue that it is only by understanding the so‐called total space that efforts can be undertaken to promote the more inclusive stakeholder collaboration, which is a prerequisite for achieving shared value for industry and society.  相似文献

Complementary techniques of midden analysis have been applied to large oyster mounds on the Richmond River, New South Wales, in order to quantify the dietary contribution of the molluscs. The results are compared with modern data on oyster yields and ethnohistorical data on diet and population size and suggest that, if oysters were the primary food supply while the shell mounds were in use, the sites would have been occupied, on the average, for as little as one week/year. The implications of this for the interpretation of molluscs as a food resource and for the use of shell middens as sources of information about economy, settlement pattern and material culture are discussed.  相似文献

The Hunter Siltstone near Grenfell, New South Wales, contains a rich Upper Devonian fish fauna including the sinolepid Grenfellaspis and the new antiarchs Bothriolepis grenfellensis sp. nov. and Remigolepis redcliffensis sp. nov. Bothriolepis grenfellensis sp. nov. is the first bothriolepid species described from N.S.W., and R. redcliffensis sp. nov. is the first species of Remigolepis described from Australia. Traditionally, the Hunter Siltstone was considered to be uppermost Famennian or earliest Carboniferous in age based on the presence of Grenfellaspis, and the related taxon Sinolepis, which is known from the Wutung and Sanmentan formations of southeastern China. However, available data indicates the Hunter Siltstone may be early Famennian in age. Ongoing work suggests that all Famennian Bothriolepis from N.S.W., including B. grenfellensis, possess a trifid preorbital recess, but differ in other aspects of headshield morphology. In North China, the Famennian Zhongning Formation contains six species of Remigolepis and a species of Sinolepis. However, R. redcliffensis does not show any similarity to these species beyond those of Remigolepis as a whole.  相似文献

Since 1955 the NSW Department of Water Resources has undertaken extensive river training works on many NSW streams. In the Hunter Valley alone over $23 million have been spent and more than 850 km of channel have been treated Published work suggests that river training works are usually undertaken in response to a pre-existing problem of river instability but can also induce adverse hydrogeomorphic effects. One of the treated streams, the Allyn River, had been supposedly degraded by the constructed works. It was alleged that vegetation clearing, channel excavations, alignment straightening and bank protection works had decreased roughness thus increasing velocity and flood frequency. As a result, what were thought to be relatively moderate floods were eroding the banks and destroying the floodplain. A critical evaluation of the available hydraulic, hydrologic and geomorphic data revealed that the river training works were a response to, rather than a cause of river instability.  相似文献

Soils in a lower Hunter valley vineyard, New South Wales, Australia, were sampled and analysed for caesium‐137, an indicator of soil erosion status, in 1984–1985 and 2004. From the time of the vineyard's first establishment in 1971 to 1985, estimated soil losses were 250 tonnes (equivalent to 64.2 t ha?1 yr?1). Re‐sampling in 2004 showed that soil losses were 48 tonnes in the 19 years since 1985, equivalent to 9.7 t ha?1 yr?1. The decline in erosion rates may be explained by a change in land and soil management from intensive cultivation to one of no cultivation (sod culture) in 1998, and a lower annual rainfall and fewer rain‐days per year in the period from 1986 to 2004.  相似文献

The new conodont Webbygnathus munusculum gen. et sp. nov. is described from Eastonian (early Late Ordovician) strata from the central part of the Parkes Zone of the Lachlan Fold Belt and the New England Fold Belt in New South Wales. In the type area south of Gunningbland, central New South Wales, the genus occurs associated with macrofossils of the coral/stromatoporoid assemblage Fauna II (early Eastonian or Ea2); in the New England region it has been obtained from strata on both sides of a major structural feature, the Peel Fault, the associated conodont assemblages indicating an age equivalent to that of coral/stromatoporoid assemblage Fauna III or late Eastonian (Ea3). The apparatus of this species, as presently known, comprises two pectiniform elements, one stellate with a four-rayed basal cavity, the other fundamentally pastinate, with a three-rayed basal cavity.  相似文献

This article considers the peculiar application of English criminal transportation law in the ‘convict colony’ of New South Wales during its foundation years. It demonstrates, first, that transportation was not intended to be within the sentencing jurisdiction of the New South Wales Court, but that it was adopted and practised nonetheless, with confused and incongruous results. In particular, substantial challenges emerged in applying colonial or local sentences to a population that was largely already under sentence of transportation. The result was a raft of innovations and inconsistencies that highlighted the legal and practical problems of performing exile in a land of exiles.  相似文献

Hypolithic plants, plants growing under rocks, have been found from a number of climatically extreme, mostly arid sites from the poles to the equator, but there are limited reports from temperate zones. A brief survey in the Kosciuszko Alpine Area of New South Wales, Australia, revealed four species of moss and one liverwort growing beneath diaphanous quartz pebbles in feldmark vegetation communities. The probable restricted nature of this phenomenon and the likely impact of global warming, tourists and recreation management activities raise concerns for its conservation.  相似文献

Luminescence dating has been applied to volcanogenic outburst flood sediments (Takuma gravel bed) from Aso volcano, Japan, and tephric loess deposits overlying the gravel bed. The poly-mineral fine grains (4–11 μm) from loess deposits were measured with pulsed optically stimulated luminescence (pulsed OSL) and post-IR infrared stimulated luminescence (pIRIR) methods, whereas the Takuma gravel bed containing no quartz, was measured with IRSL and pIRIR methods using sand sized (150–200 μm) plagioclase. The loess deposits date back at least to ~50 ka by consistent IRSL, pIRIR and pulsed OSL ages from the lowermost part of the loess deposits from one section. The ages obtained from the bottom part of the other loess section are not consistent each other. However, we consider that the pIRIR age (72±6 ka) which showed negligible anomalous fading is most reliable, and regard as a preliminary minimum age of the Takuma gravel bed. The equivalent doses (De) for the plagioclase from the Takuma gravel bed have a narrow distribution and the weighted mean of the three samples yield an age of 89±3 ka. This age is in agreement with the last caldera-forming eruption of Aso volcano (~87 ka) and it is likely that the pIRIR signal has not been bleached before the deposition. IRSL dating without applying pIRIR using small aliquots was also conducted, however, the IRSL signal shows no clear evidence of an additional bleaching during the event of outburst flood from the caldera lake.  相似文献

This article discusses youth out‐migration on the non‐metropolitan New South Wales Eastern Seaboard. High levels of in‐migration and counter‐urbanisation, typical of many coastal non‐metropolitan towns in NSW, mask the out‐migration of youth. There are relatively few 15–24 year olds in the coastal communities of non‐metropolitan New South Wales, because many youths out‐migrate to larger centres, for a range of reasons. Out‐migration also demarcates a life transition away from school life, adolescence and the parental home. This paper draws from research with senior high school students in one coastal town – Coffs Harbour – where such trends have been particularly apparent. It examines the propensity for youth out‐migration and discusses how young people articulate their migration intentions. Young people's perceptions of their current and future prospects feature prominently in their discourses about intended migration, although this research also demonstrates that the life courses of regional youth are unorthodox and diverse in nature.  相似文献

Based mainly on Australian press reportage from 1927 to 1932, when Lord Strickland held office in Malta, this article explores a mirror-like image of goings-on in a geographically far removed part of the one empire. Included in this are telling but so far barely known flashbacks from the same sources to the time when the Anglo-Maltese politician had served as a governor of three Australian states, with special reference to New South Wales, until 1917. Albeit in different ways and for diverse reasons, certain personality traits, as well as issues relating to church-state, intra-institutional and centre-periphery relations, evoked a resonance in Australia as they did in Malta. As far as governance was concerned, in Strickland's New South Wales the tension was between governor, premier and parliament, as well as to a lesser extent between state and federal roles whereas in Malta it was between a legislative assembly and senate dominated by different parties in a diarchy, with dissonant pulls by London and Rome.  相似文献

A survey of 421 children and 165 parents from three suburban primary schools in Newcastle, New South Wales, Australia has provided information on the nature and location of children’s play, both at present and a generation ago. Although modern children have greater access to individual transport in the form of higher bicycle ownership, other constraints appear to have restricted their play space. These include the availability of home-based leisure technology such as computer games and greater parental restriction on where children might play. The results of the survey would appear to indicate that children prefer to play at home. However, analysis of the children’s stories and drawings suggests that, given the chance, a majority of children would choose to engage in outdoor activities in the bush, in parks or on the beach. Their actual choice of play space may thus be determined by a knowledge of parental constraints.  相似文献
