Effects of fragmented habitat and fire on the distribution and ecology of the swamp antechinus (Antechinus minimus maritimus) in the Eastern Otways, Victoria

This study investigated the distribution, habitat and population dynamics of the swamp antechinus (Antechinus minimus maritimus) in the eastern Otway Ranges. The species has a restricted, disjunct distribution and has been recorded at 25 sites between 1969 and 1999. All sites were located within 7 km of the coast, occurred at altitudes up to 80 m above sea level and within 10 m of a gully. Analysis of landscape site variables identified sun index as being significant in determination of the probability of occurrence of A. minimus. The presence of A. minimus is negatively associated with sun index, occuring at sites that have a southerly aspect and gentle slope. A. minimus was located in a range of structural vegetation including Open Forest, Low Woodland, Shrubland and Hummock Grassland and a number of floristic groups, some characterised by high frequencies of sclerophyll shrubs, others by high frequencies of Pteridium esculentum, hummock grasses and herbaceous species. A. minimus occurs in fragmented, small populations with maximum population densities of 1.1–18 ha^–1. Populations at inland sites became extinct after the 1983 wildfire which burnt 41 000 ha. These sites have not been recolonised since, while on the coast the species did not re-establish until 1993–97. One population that is restricted to a narrow coastal strip of habitat is characterised by high levels of transient animals. The species is subject to extinction in the region due to habitat fragmentation, coastal developments and fire. Management actions to secure the present populations and ensure long-term survival of the species in the area are required and include implementation of appropriate fire regimes, prevention of habitat fragmentation, revegetation of habitat, and establishment of corridor habitat.

John Martyn Harlow: 'obscure country physician?'

If John Martyn Harlow is known at all in the neurosciences, it is because he was the physician who attended Phineas Gage and followed up his case. Although Harlow's brief but insightful accounts of the changes in Gage's personality are fairly well recognized, and his skill in treating Gage often acknowledged, Harlow himself is, for the most part, the shadowy figure caught by the self-depreciatory characterization of the subtitle of this paper. Although his contribution to the neurosciences was singular, literally and figuratively, he deserves a place in the history of the subject. Harlow's training in antiphlogistic therapy can be seen in his treatment of Gage and in his evaluation of its results. As a medical student, he was also exposed to phrenological doctrine, the influence of which can also be seen in his  appreciation and explanation of some aspects of Gage's behaviour.  Manuscript materials, newspaper reports, and other little known material are used here to evaluate Harlow's contributions to medicine and to the medical, political, and civic life of Cavendish, Woburn, and the Commonwealth of Massachusetts.

Filching the Argentine colonists : the encouragement of Patagonians to the Northern Territory in the early twentieth century

This paper explores the background to the emigration of 220 settlers from Patagonia in South America to the Northern Territory during the course of World War I. The group, which arrived in Darwin on the Kwanto Maru in 1915, comprised an unusual mixture of nationalities. The breakdown given in the passenger list and the contemporary press was 113 Spaniards, 45 Russians, 30 Italians. 28 British, I Argentinian [of British parents], 1 Frenchman, 1 Serbian and 1 Greek. Some of the 'Spaniards' were presumably Spanish speaking Argentinians but most were indeed of Spanish descent, such as the Martinez, Perez and Villalba families. Of the British amongst the group, almost all were Welsh. They came as a result of inducements held out to the Welsh amongst the party in the years immediately prior to the war by the Commonwealth Government, which administered the Northern Territory after 1911. This account provides a fascinating case study of the recruitment of immigrants to Australia, and particularly to the Northern Territory, in the early twentieth century.

The political economy of maritime industry non-reform in interwar Australia: the establishment of the Maritime Services Board of New South Wales

From the First World War Australian port administration came under criticism from exporters, shipping companies and the Commonwealth government, all of whom argued that port authorities charges imposed an excessive burden on exporters. They sought the replacement of public port authorities by trusts representative of business interests. The campaign for port administration reform also diverted farmers from criticism of shipping freights and to secure their acquiescence in anti-competitive practices in the shipping industry. The formation of the Australian Overseas Transport Association in 1929 was the culmination of this campaign. Elite conservative political support for such anti-competitive practices reflected a belief that competitive capitalism was inherently unstable. The Scullin Labor of 1929-31 government abandoned Labor's earlier hostility to shipping companies to support cartelisation. Conservative state governments, in a more competitive electoral position than their federal counterparts and under greater financial pressure, deflected business calls for port administration reform. Business groups expected the NSW conservative government elected in 1932 to reform port administration towards a representative model, but the Maritime Services Board established in 1935 merely rationalised existing administrative structures. In the 1980s international economic instability legitimated the project of microeconomic reform, particularly in the maritime sector, but in the interwar period a different balance of capital, labour and the state meant that economic isolationism rather than integration was the policy outcome.

Data protection and privacy: the Australian legislation and its implications for IT professionals

The notion of privacy takes on a completely different meaning when viewed from the perspective of an IT professional, an organisation using technology to support strategic directions or a member of the public. This paper looks past the technical issues involved in data protection and examines some of the business, social and regulatory aspects that have become important to those involved in the management, storage and dissemination of electronic information. The paper documents some of the legislative developments in privacy and data protection and examines what these developments mean for IT professionals for whom the link between data captured, stored and processed into information and the resulting effect on privacy is important. The Commonwealth Privacy Act 1988 based on work done by the Council of Europe, the OECD and the European Union provides some general guidelines but only for the public sector. However, new legislation imminent. Thus, IT professionals need to be aware of the changing situation and examine their organisation’s current practices to ensure compliance with future laws.

Policy implications of the transfer of ownership of Scotia Sanctuary for the National Reserve System in Australia

The recent purchase of Scotia Sanctuary, in western New South Wales, by the Australian Wildlife Conservancy (AWC), with significant funding from the Commonwealth government raises questions about the National Reserve System in Australia. The property had been placed on the market by the financially strapped Earth Sanctuaries Ltd (ESL). The Commonwealth's involvement represents an important landmark in private land conservation. This commentary investigates some of the possible policy implications this intervention may have for the National Reserve System as a whole and, in particular, about the role of private land within this System.

Integrated natural resource management in Australia: the opportunity offered by a national coastal policy

Under the Australian Constitution the management (and planning) of Crown Land is a State and Territory Government responsibility. When this is considered in conjunction with the Offshore Constitutional Settlement, which affirmed that coastal waters out to three nautical miles (in general) offshore were also the responsibility of State and Territory Governments, then clearly coastal management in Australia is largely a State/Territory responsibility.

Beyond three nautical miles it is a different story. Under the United Nations Law of the Sea Convention (UNCLOS), which Australia ratified in October 1994, Australia claims jurisdiction out to 200 nautical miles and beyond (Wescott, 2000). These waters cover an area including the Antarctic claim of over 15 million square kilometres or twice the land area of Australia.

Hence in marine and coastal terms we have the national (Commonwealth) Government managing the oceans and seven State and Territory governments largely in charge of coastal management (coastal land and coastal waters). Heading "up river", State and Territory Governments plan and manage catchments.

Given the uncoordinated relationships between Australian coastal management policy and both catchment management policy and Australia's Ocean Policy (Commonwealth of Australia, 1998a and b), the Commonwealth Government's commitment to a "National Coastal Policy" presents an opportunity to progress the integration of natural resources management for the first time in decades.

Macmillan, Menzies, history and empire

In response to the rapidly changing nature of the British Commonwealth and Empire in the early 1960s Harold Macmillan and Robert Menzies exchanged correspondence which reflected upon the history of the British Empire and the world. In this article I argue that in their exchanges and other writings over this history we can identify, to use William Appleman Williams' formulation, the 'common assumptions about reality' which were crucial in shaping their understanding of world affairs.

Caste, land and livestock holdings in India: an analysis

A ban on grazing, particularly by small ruminants, forms an important component of the Forest Policy and Joint Forest Management arrangements in India. Some caste groups keep larger number of small ruminants than the others. It is considered as a social trait that is sought to be corrected through extension efforts. This paper analyses the livestock structure of households by using a model of household behaviour based on profit maximisation. It shows that landholding plays a crucial role in livestock structure of households and because certain caste groups have smaller landholding they tend to keep small ruminants that can feed on the common lands and forest areas. The policy of a ban or restriction on grazing adversely affects such caste groups who therefore come to resent it.

Floristic and structural characteristics of a coastal heathland exhibiting symptoms of Phytophthora cinnamomi infestation in the eastern Otway Ranges, Victoria

The floristics and structure of heathland vegetation exhibiting symptoms of Phytophthora cinnamomi Rands infestation was assessed at two sites in heathlands at Anglesea, Victoria. There were significant effects in both floristics and structure. Thirteen heathland species were significantly less abundant in diseased areas and 23 species were more abundant. Diseased (infested) vegetation, when compared with non-diseased areas, had less cover of Xanthorrhoea australis and shrub species and a greater cover of sedges, grasses and open ground. Structural differences were observed between heights 0 and 0.6 m, with a decline in cover recorded in diseased vegetation. Non-metric multidimensional scaling ordination of the floristic data showed a clear separation of diseased and non-diseased vegetation and that changes in floristic composition post-infestation were similar at both sites. Although there was some evidence of regeneration of X. australis, the recovery capacity of other susceptible species at Anglesea is unknown. The long-term consequences of loss of species and structure in the eastern Otways mean that the vegetation is unlikely to return to former status, especially if the pathogen continues to reinfect.

The taxonomy and phylogeny of the Cherax destructor complex (Decapoda : Parastacidae) examined using mitochondrial 16S sequences

This study uses nucleotide sequences from the 16S rRNA mitochondrial gene to investigate the taxonomy and phylogeny of freshwater crayfish belonging to the 'Cherax destructor' complex. The sequencing of an approximately 440-bp fragment of this gene region from freshwater crayfish sampled from 14 locations identified significant haplotype diversity. Phylogenetic analysis found three distinct clades that correspond to the species C. rotundus, C. setosus and C. destructor. C. rotundus is largely confined to Victoria, and C. setosus is restricted to coastal areas north of Newcastle in New South Wales. C. destructor is widely distributed in eastern Australia and shows significant phylogeographic structure, with three well supported clades. None of these clades, however, correspond to species previously recognised as C. esculus, C. davisi or C. albidus. The failure to genetically distinguish these morphologically defined species is consistent with reproductive information and morphological plasticity relating to habitat similar to that documented for other Cherax species.

So far so good? : A critical evaluation of racial vilification laws in Australia

Problems with Australia's racial vilification laws - s 18C of the Commonwealth's Racial Discrimination Act - free speech and public interest defences under the Racial Discrimination Act as well as State and Territory racial vilification laws - impact of free speech cases on the content of the racial vilification defences.

Back to the future : the war on terror and its impact on civil liberties

This comment looks at the capacity of the Australian Constitution to protect the civil liberties of a small number of citizens and would be citizens whose lives have been forever changed by recent acts of terror and the legislative and executive actions taken by the Commonwealth in response to those terrorist acts. These legal changes have included the creation of specific "terrorism" offences, the legislative proscription of two foreign organisations and, most notably, a significant expansion of ASIO's investigative powers.1
Whilst the Constitution contains a number of provisions and principles protective of civil liberties, in most instances they cannot resist government action expressly aimed at curtailing or infringing individual rights and freedoms. To this end, steps ought to be taken to strengthen existing institutions and mechanisms capable of providing meaningful civil rights scrutiny of government legislation. The comment begins with an examination of the close historical and legal parallels that exist between the present day and the Cold War era and suggests how the High Court might interpret the defence power should a terrorist attack occur on Australian soil. It concludes with a proposed reform. The reform involves vesting Ch III courts with the power to measure Commonwealth laws against the International Covenant on Civil and Political Rights when determining a legal controversy. This may operate to secure better legislative outcomes from a civil liberties perspective without compromising the supremacy of Parliament.

The Bishop of Carpentaria and the Torres Strait pearlers' strike of 1936

The exploitation of Islander pearl divers in Torres Strait and the Queensland Government's control of divers' wages was the major cause of a strike by 400 divers in 1936. The strike was also fuelled by overall discontent with the Queensland Government's rule and a desire to be free of the Queensland Protectors. An address in 1935 by Stephen Davies, Bishop of Carpentaria, urging the Commonwealth of Australia to strip Queensland and other states of management of Island and Aboriginal affairs provided the catalyst. Davies's Torres Strait Island clergy played a pivotal role in the resistance to state control. One lasting effect of the strike lay in the introduction of elected Islander councils in 1937, but what happened subsequently allowed the perpetuation of Queensland control through the new Department of Native Affairs. The results of the strike fell short of the complete transfer to the Commonwealth that the Torres Strait pearl divers and clergy had envisaged.

The systematics of freshwater crayfish of the genus Cherax Erichson (Decapoda : Parastacidae) in eastern Australia re-examined using nucleotide sequences from 12S rRNA and 16S rRNA genes

Nucleotide sequence data were used to re-examine systematic relationships and species boundaries within the genus Cherax from eastern Australia. Partial sequences were amplified from the 12S (~365 bp) and 16S (~545 bp) rRNA mitochondrial gene regions. Levels of intra- and inter-specific divergence for Cherax species were very similar between the two gene regions and similar to that reported for other freshwater crayfish for 16S rRNA. Phylogenetic analyses using the combined data provided strong support for a monophyletic group containing 11 eastern Australian species and comprising three well-defined species-groups: the 'C. destructor' group containing three species, the 'C. cairnsensis' group containing four species and the 'C. cuspidatus' group containing two species. Cherax dispar and C. robustus are distinct from all other species and each other. In addition, two northern Australian and a New Guinean species were placed in the 'Astaconephrops' group, which is the sister-group to the eastern Australian Cherax lineage. Several relationships were clarified, including: the status of northern and southern C. cuspidatus as separate species; a close relationship between C. cairnsensis and C. depressus; the validity of C. rotundus and C. setosus as separate species and their close affinities with C. destructor; and the distinctiveness of the northern forms of Cherax. The analysis of the 12S rRNA and 16S rRNA data is highly concordant with the results of previous allozyme studies.
