Legacies of White Australia : race, culture and nation

The White Australia policy continues to haunt Australia. Here, leading Australian scholars provide an informed debate on the essential issues of race, identity and nation that will determine our attitudes to immigration, multiculturalism and Australian-Asian engagement in the twenty-first century.

Studies on physiologic specialisation of albugo candida causing white blister on broccoli in Victoria

White blister caused by oomycete Albugo candida (Pers. Ex. Lev.) Kuntze, (AC), is an important disease affecting many cruciferous hosts, including vegetable brassicas. The outbreaks of white blister in broccoli and cauliflower crops (Brassica oleracea var. italica and var. botrytis) in Southern Australia in the last three years led to restrictions on movement of fresh produce and seedlings from the disease-affected areas. Current classification of AC races is based on physiologic specialisation of this pathogen. Race 9 has been identified to cause white blister on B. oleracea in the USA. We report on specialisation of AC causing disease in Victorian broccoli crops and the use of molecular tools for the separation of AC races. In a glasshouse, 12 Brassicaceae species/varieties replicated 6 times, were inoculated twice at the fully developed cotyledon stage with a distilled water suspension of zoosporangia (1x104 per ml) collected from a single broccoli leaf. Two weeks after inoculation the incidence of white blister on cotyledons and seedling leaves of cauliflower, broccoli, black mustard and Indian mustard was 79.7, 78.4, 73.7 and 6.9% respectively. Cabbage plants were symptomless indicating that further specialisation of the pathogen may have occurred in Australia. High disease incidence among black mustard plants shows that the Australian isolate differs from overseas AC race 9. The interaction of a number of B. oleracea varieties to a range of AC isolates from various hosts will be investigated. Degenerate primers are now being used to amplify actin and β-tubulin genes to identify race specific polymorphisms in AC isolates from three different hosts (wild radish, Chinese cabbage, and broccoli). Differing PCR amplification efficiencies from broccoli and wild radish isolates using degenerate actin primers indicates sequence differences in the two isolates. The fragments are now being cloned and sequenced for race comparison.

Distribution and abundance of the white-faced storm petrel (Pelagodroma marina) in Victoria

Habitat loss and modification is a major factor driving reductions of seabird populations. The white-faced storm petrel (Pelagodroma marina) is restricted to three breeding colonies within Victoria: Mud Islands and South Channel Fort in Port Phillip Bay, and Tullaberga Island off Mallacoota. The numbers of storm petrels breeding on Mud Islands and South Channel Fort have declined considerably, possibly a result of the significant vegetation changes, together with increases in local populations of other species of birds, most notably, silver gulls (Larus novaehollandiae). On Mud Islands the breeding area available to the storm petrels appears to be limited by the recent arrival of the Australian white ibis (Threskoirnis molucca), and straw-necked ibis (T. spinicollis) which now breed on the islands in large numbers (approximately 15,000 pairs). The impact of these changes on the storm petrels is poorly understood. The current status of storm petrels at Tullaberga Island is unknown. This study estimated the size of the breeding population at all three sites by determining burrow densities, and a burrow-scope was used to determine occupancy. Burrow density was found to be related to vegetation type and other habitat factors. This study has highlighted important information on the breeding habitat of the white-faced storm petrel and the implications for management are discussed.

Not quite white (enough) : intersecting ethnic and gendered identities in 'Looking for Alibrandi'

The intersections between raced and gendered identity, treating identity-formation as a function of biological, cultural and ideological codifications that cannot be readily disentangled is assessed by an analysis of the novel Looking for Alibrandi. This novel embodies this intersection of identity politics in ways that suggest that rethinking multiculturalism and whiteness also mean rethinking gender.

Fatty acid composition and volatile compounds of caviar from farmed white sturgeon (Acipenser transmontanus)

The present study was conducted to characterize caviar obtained from farmed white sturgeons (Acipenser transmontanus) subjected to different dietary treatments. Twenty caviar samples from fish fed two experimental diets containing different dietary lipid sources have been analysed for chemical composition, fatty acids and flavour volatile compounds. Fatty acid make up of caviar was only minimally influenced by dietary fatty acid composition. Irrespective of dietary treatments, palmitic acid (16:0) and oleic acid (OA, 18:1 n-9) were the most abundant fatty acid followed by docosahexaenoic acid (DHA, 22:6 n-3) and eicopentaenoic (EPA, 20:5 n-3).

Thirty-three volatile compounds were isolated using simultaneous distillation–extraction (SDE) and identified by GC–MS. The largest group of volatiles were represented by aldehydes with 20 compounds, representing the 60% of the total volatiles. n-Alkanals, 2-alkenals and 2,4-alkadienals are largely the main responsible for a wide range of flavours in caviar from farmed white surgeon
