Testo completoAbstract (sommario):
Much recent academic and public discourse has centred on the fate of non-metropolitan Australia under successive federal neoliberal reform agendas. This paper discusses creative networks in non-metropolitan areas in light of this, with a focus on issues of youth unemployment and out-migration. First, it draws on research on creative industry development on the New South Wales Far North Coast to assess the efficacy of creative networks as a source of new job growth in rural areas. Second, and more broadly, the paper discusses the North Coast Entertainment Industry Association (NCEIA), a nascent creative network in the region. Several observations are drawn from its experiences. Creative networks in non-metropolitan areas face problems of informal and itinerant membership, and anti-socialisation attitudes, Yet they appear to have a substantial role in improving the conditions of viability for vulnerable cultural producers. When conceived as part of interventionist strategies to promote youth employment and to stem the youth exodus from rural areas, they may also have sociodemographic implications beyond the scope of their original intent.

Testo completoAbstract (sommario):
During the last 10-15 years intestinal infections caused by parahaemolytic vibrio have been registered in many countries of Asia, Europe, South and North America and in Australia. The frequency of isolation of this pathogen from patients varies from 1.5 to 15%. In Japan, parahaemolytic vibrios has become a national problem. In the vast majority of cases, parahaemolytic vibrio-induced illnesses have been shown to be associated with exposure to seawater and consumption of seafood, even when they occur in areas far from the sea.

Whan, I., G. Bortolussi e R. Backus. "The impact of innovation on beef production in far northern Australia". Australian Journal of Experimental Agriculture 46, n. 2 (2006): 271. http://dx.doi.org/10.1071/ea05175.
Testo completoAbstract (sommario):
In this paper we examine the forces that have shaped Australia’s far northern (north of 20° south) beef industry over the past 35 years. This is done for the purpose of tracing its transformation from a state of relative isolation to an integral part of the national beef industry. We note that integration is being accompanied by a greater focus, particularly by corporate producers, on specialised breeding in the far north and this is being assisted by innovations that increase herd fertility and raise the meat quality of the progeny, while retaining adaptation of the breeding herd to the local environment. Among a range of technologies, genetic improvement has significant potential to bring about rapid improvement in the meat quality of tropically adapted cattle. With respect to gene-based technology, however, independent producers will have to be convinced about the rigour of the technology and the prospects of economic gains before they make significant management changes. To this end, innovative marketing systems are needed that will reveal the link between expected meat returns and the offer prices applying to groups of growing cattle in any location. Accordingly, there is an urgent need to develop and introduce a descriptive and informative trading language for growing cattle that incorporates inherent qualities including those that influence meat quality. Innovations that will complement those applying to enhancement of meat quality are more general but will significantly raise herd productivity. We also compare the operating systems of both corporate and independent producers in the region.

Testo completoAbstract (sommario):
Every year, millions of migratory birds journey along the East Asian-Australasian Flyway (EAAF). The scope of the EAAF encompasses Asia Pacific nations like Australia, New Zealand, China, Japan, South Korea, Vietnam, Malaysia and Indonesia. The effective conservation of these birds rests upon the implementation of bilateral legal agreements as well as non-binding regional initiatives along this North-South nexus. This article evaluates the implementation of one of the most important bilateral bird agreements in the region – the China-Australia Migratory Bird Agreement (CAMBA). The main obligations in CAMBA are identified; as are the legal initiatives adopted by both China and Australia which reflect CAMBA's obligations. Whilst Australian law makes specific reference to CAMBA, Chinese law is far less direct, though perhaps no less effective. The argument is made that the findings in this article have relevance for an improved understanding of the mechanisms for transboundary governance of migratory birdlife, especially in the Asia Pacific.

Testo completoAbstract (sommario):
Social Return on Investment (SROI) is an internationally recognised methodology used to measure and value the economic impact of program outcomes. Like a traditional cost-benefit analysis, SROI examines economic outcomes, but also includes the social, environmental and cultural outcomes created by the investment. These outcomes are evaluated against their cost, using financial proxies to estimate their relative economic worth. SROI is particularly valuable in the indigenous natural resource management context, because of the strong ‘value’ or importance of non-economic (particularly cultural) costs and benefits. The Alinytjara Wilurara Natural Resources Management Board undertook a study of the economic, social, environmental and cultural impacts and benefits of the presence of large feral herbivores in the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands, in the far north-west of South Australia. Camels, donkeys and horses present significant impacts for the community in terms of vehicle collisions, community health, damage to infrastructure and water pollution, as well as impacts on sites of cultural and spiritual significance to the local communities. With the annual cost impacts incurred by society caused by large feral herbivores in the APY lands valued at $4.2million and possible dollar value of those animals valued at $140000, the study found that there was a net cost impact of ~$4million from not managing the impact of these animals. The study also found significant cultural impacts of large feral herbivores, such as the fouling of natural springs and other culturally sensitive sites, and further analysis would be required to determine the economic cost of these impacts. Investment models that consider a broad range of costs and benefits are considered necessary for Australian rangelands, particularly Indigenous-owned land. This paper presents a case study of the development of a ranger program that employs local community members to manage the impacts of large feral herbivores that will provide a net benefit to society of ~$3million every year, aside from the additional benefits of employment and economic participation. The $3-million net benefit accrues from saving human lives and costs associated with vehicle accidents, and reduced management costs and increased income for pastoral areas of the APY Lands. APY community members, and the APY Pastoral business are core beneficiaries; however, there are several external beneficiaries that this SROI approach recognises including the Motor Accident Commission, Health Departments and South Australian Police. The strongly positive SROI in this case presents an excellent co-investment opportunity for agencies whose core focus is on road safety and health. Importantly, the SROI approach to creation of social value can be implemented in a way that is consistent with stated community aspirations for development.

Giles, Robyn L., Andrew N. Drinnan e Neville G. Walsh. "Variation in Phebalium glandulosum subsp. glandulosum: morphometric and anatomical evidence (Rutaceae)". Australian Systematic Botany 21, n. 4 (2008): 271. http://dx.doi.org/10.1071/sb07023.
Testo completoAbstract (sommario):
Specimens of Phebalium glandulosum Hook. subsp. glandulosum representing the entire geographic range of the subspecies were examined for morphological and anatomical variation. Phenetic patterns were identified with the pattern analysis package PATN, and three distinct groups were identified. One group consists of plants from inland areas of New South Wales, north-western Victoria, and the Yorke and Eyre Peninsulas of South Australia; a second group consists of plants collected from alongside the Snowy River in eastern Victoria and south-eastern New South Wales; and a third group consists of plants from Queensland and northern New South Wales. The climate analysis program BIOCLIM was used to compare climate variables across the geographic range, and showed clear climatic separation in support of the phenetic analysis. The three groups are formally recognised here as distinct subspecies. Plants from Queensland and the Bourke region of northern New South Wales belong to the typical subspecies; plants from north-western Victoria, central New South Wales, and the Yorke and Eyre Peninsulas of South Australia form a cohesive assemblage and are recognised as a new subspecies P. glandulosum subsp. macrocalyx; and plants from the Snowy River in far eastern Victoria and the Southern Tablelands of New South Wales form a distinct and isolated group recognised as a new subspecies P. glandulosum subsp. riparium. These new subspecies are formally described, and an identification key and summaries distinguishing all six subspecies of P. glandulosum are presented.

Testo completoAbstract (sommario):
AbstractOn the west coast of North America and in Australia, there have been parallel cases of sequential invasion and replacement of the shoreline plant American sea-rocket by European sea-rocket. A similar pattern has also occurred in New Zealand. For 30 to 40 yr, from its first recording in 1921, American sea-rocket spread throughout the eastern coastlines of the North and South Islands of New Zealand. European sea-rocket has so far been collected only on the North Island. From its first collection in 1937, European sea-rocket spread to the northern extremity of the island by 1973, and by 2010, it had reached the southernmost limit. In the region where both species have occurred in the past, American sea-rocket is now rarely found. This appears to be another example of congeneric species displacement.

Testo completoAbstract (sommario):
The Oobagooma Sub-basin of the Roebuck Basin includes the offshore extension of the onshore Fitzroy Trough of the Canning Basin. Together with the Leveque Platform, it covers an area of approximately 50,000 km2, yet only 14 exploration wells have been drilled in the area to date, five of which were drilled in the past 30 years. The sub-basin contains sediments ranging in age from Ordovician to Recent. This study examines the petroleum prospectivity of a region that is one of the least explored on Australia’s North West Shelf. Recent exploration drilling has revived interest in the area, with the 2014 Phoenix South–1 oil discovery in the offshore Bedout Sub-basin and the 2015 Ungani Far West–1 oil discovery in the onshore Fitzroy Trough. The two most significant source rock sequences relevant to the Oobagooma Sub-basin are the Carboniferous Laurel Formation and the Jurassic section. The former interval is part of a proven petroleum system onshore and is the source of the gas discovered at Yulleroo and oil at Ungani and Ungani Far West. A thick Jurassic trough to the north of the Oobagooma Sub-basin is believed to be the source of the oil and gas in Arquebus–1A and gas in Psepotus–1. Hydrocarbon charge modelling indicates significant expulsion occurred during both the Cretaceous and Tertiary from both source intervals. Trap timing is generally favourable given that inversion structures formed in several episodes during the Late Jurassic to Late Tertiary. The Early Triassic, now proven to be oil prone in the Phoenix South area (Molyneux et al, 2015), provides an additional (albeit less likely) source for the Oobagooma Sub-basin. These rocks are thin to absent within the Oobagooma Sub-basin, so long-distance migration would be required from deep troughs to the west.

Testo completoAbstract (sommario):
The helminth fauna from 124 water-rats, Hydromys chrysogaster, collected from 33 localities in Queensland was analysed. A total of 45 species of helminths was found, comprising 2 acanthocephalans, 2 cestodes, 13 nematodes and 28 trematodes. The helminth community of the water-rats in the region north of latitude 18˚ (far north) was different from that of water-rats south of 18˚ (central); Sorensen’s Index 45·8% similarity, whereas Holmes and Podesta’s Index gave 32·1% similarity. Comparisons with data from water-rats from southern and Tasmanian regions showed that they were different from each other and from both Queensland regions. The helminth communities were characterised by high diversity, dominated by trematodes in the central and Tasmanian regions, but with nematodes becoming more prominent in the far northern and southern regions. No core or secondary species were found in the Queensland helminth communities, the southern community was suggestive of a bimodal distribution and the Tasmanian had two core species. A checklist of helminth species occurring in water-rats from eastern Australia is provided.

"Updated catalog and generic keys of the Leiodidae (Insecta: Coleoptera) of the Neotropical region (“Latin America”: Mexico, the West Indies, and Central and South America)". Zootaxa 4741, n. 1 (18 febbraio 2020): 1–114. http://dx.doi.org/10.11646/zootaxa.4741.1.1.
Testo completoAbstract (sommario):
This paper presents an updated catalog of all taxa of Leiodidae (s.lat.) reported from the Neotropical Region. Keys are presented for the identification of all subfamilies, tribes, and 62 described genera. Three undescribed genera are included in the keys. A total of 600 valid named species are listed, with type localities, type depositories, synonyms, distributions, and biologies where known, and some unnamed species as recorded in the literature. Many species remain to be described. In this work we formally establish no new synonyms and no new combinations although we may indicate the existence of these; but we add new records for described species, and we make spelling corrections of scientific names, when appropriate. A brief review of distribution patterns is given. The fauna has been derived partly from some Nearctic elements that have penetrated as far south as Bolivia. A few genera in the Neotropical element have penetrated the Nearctic Region as far north as the northern U.S.A. or southeastern Canada. Most of the Neotropical genera are autochthonous. In southern South America there is a diverse Neo-Austral fauna with clear “Transantarctic” relationships to Australia and New Zealand and weakly to southern Africa. Some genera variously occur on other continents.

Accompanying CD-ROM inside back cover, includes Appendices. Bibliography: leaves 242-266. This thesis examines the effects on vegetation at selected sites in northern South Australia of excluding various herbivores over a four and a half year period and of two intense but controlled grazing pulses over a six month period followed by an 18 month recovery period in a dune-swale land system. These changes are compared with changes recorded over an 11-year period at the Olympic Dam mine site. It found that short-term changes in vegetation revealed by ordination of periodical cover, density and species richness, are attributable to the periodicity of rainfall and that, under present grazing regimes, rainfall effects override grazing effects. Differences between the effects of sheep and cattle hoof damage are worthy of further investigation, as is the impact of kangaroo grazing. These two factors may have important implications for the management of Australian rangelands.

Testo completoAbstract (sommario):
Pictures of Time Beneath examines three celebrated heritage landscapes: Adelaide’s Hallett Cove, Lake Callabonna in the far north of South Australia, and the World Heritage listed Willandra Lakes Region of New South Wales. It offers philosophical insights into significant issues of heritage management, our relationship with Australian landscapes, and an original perspective on our understanding of place, time, nation and science.
Glaciers in Adelaide, cow-sized wombats, monster kangaroos, desert dunes littered with freshwater mussels, ancient oases and inland seas: a diverse group of deep-time imaginings is the subject of this ground-breaking book. Ideas about a deep past in Australia are central to broader issues of identity, belonging, uniqueness, legitimacy and intellectual community. This journey through Australia’s natural histories examines the way landscapes and landforms are interpreted to realise certain visions of the land, the nation and the past in the context of contemporary notions of geological heritage, cultural property, cultural identity and antiquity.

Hutchison, Charles S. "The Geological Framework". In The Physical Geography of Southeast Asia. Oxford University Press, 2005. http://dx.doi.org/10.1093/oso/9780199248025.003.0011.
Testo completoAbstract (sommario):
This chapter outlines the principal geological features of the region, extending from Myanmar and Taiwan in the north, southwards to include all the ASEAN countries, and extending as far as northern Australia. The present-day lithospheric plates and plate margins are described, and the Cenozoic evolution of the region discussed. Within a general framework of convergent plate tectonics, Southeast Asia is also characterized by important extensional tectonics, resulting in the world’s greatest concentration of deep-water marginal basins and Cenozoic sedimentary basins, which have become the focus of the petroleum industry. The pre-Cenozoic geology is too complex for an adequate analysis in this chapter and the reader is referred to Hutchison (1989) for further details. A chronological account summarizing the major geological changes in Southeast Asia is given in Figure 1.2. The main geographical features of the region were established in the Triassic, when the large lithospheric plate of Sinoburmalaya (also known as Sibumasu), which had earlier rifted from the Australian part of Gondwanaland, and collided with and became sutured onto South China and Indochina, together named Cathaysia. The result was a great mountain-building event known as the Indosinian orogeny. Major granites were emplaced during this orogeny, with which the tin and tungsten mineral deposits were genetically related. The orogeny resulted in general uplift and the formation of major new landmasses, which have predominantly persisted as the present-day regional physical geography of Southeast Asia. The Indo-Australian Plate is converging at an average rate of 70 mm a−1 in a 003° direction, pushed from the active South Indian Ocean spreading axis. For the most part it is composed of the Indian Ocean, formed of oceanic sea-floor basalt overlain by deep water. It forms a convergent plate margin with the continental Eurasian Plate, beneath which it subducts at the Sunda or Java Trench. The Eurasian continental plate protrudes as a peninsular extension (Sundaland) southwards as far as Singapore, continuing beneath the shallow Straits of Malacca and the Sunda Shelf as the island of Sumatra and the northwestern part of Borneo.
