The bloom was mapped and extensive mats of L majuscula were observed overgrowing seagrass beds along at least 18 km of coast, and covering a surface area of more than I I km(2). Higher than average rainfall preceded the bloom and high water temperatures in the preceding summer may have contributed to the bloom. In bloom samples, lyngbyatoxin A (LA) was found to be present in low concentration (26 mu g kg(-1) (dry weight)), but debromoaplysiatoxin (DAT) was not detected. The diet of 46 green turtles was assessed during the bloom and L. majuscula was found in 51% of the samples, however, overall it contributed only 2% of the animals' diets. L. majuscula contribution to turtle diet was found to increase as the availability of the cyanobacterium increased. The bloom appeared to have no immediate impact on turtle body condition, however, the presence of a greater proportion of damaged seagrass leaves in diet in conjunction with decreases in plasma concentrations of sodium and glucose could suggest that the turtles may have been exposed to a Substandard diet as a result of the bloom. This is the first confirmed report of L. majuscula blooming in winter in Shoalwater Bay, Queensland, Australia and demonstrates that turtles consume the toxic cyanobacterium in the wild, and that they are potentially exposed to tumour promoting compounds produced by this organism.

However the problems of Aboriginal housing are unlikely to ever be resolved until they are adequately understood. Dr Memmott reviews the problems and suggests how the search for long term solutions might be begun. 2005-08-30T00:00:00Z Memmott, Paul http://espace.library.uq.edu.au/view/UQ:65056 2007-08-14T19:35:09Z Fantin, S.

A. http://espace.library.uq.edu.au/view/UQ:160074 This paper discusses the cultural characteristics of aged persons that facilitate planning of their future accommodation. It involves the identification of cultural values of the individual elderly, the rural/urban location, and the identification of loadings on those values. The key operative variables of the accommodation system are preserving face, a desire for harmony, with compliance a third factor. These values have been shown to influence the decisions on housing accommodation, particularly in determining change in accommodation and barrier free spatial forms in the housing environment, and shaping free flowing interaction with the community and choice in housing options. 2009-01-07T14:57:22Z Mohd Yusof, Yusnani http://espace.library.uq.edu.au/view/UQ:160075 This paper discusses the cultural characteristics of aged persons which facilitate planning of their future accommodation. It involves the identification of cultural values of the individual elderly, the rural/urban location, and the identification of loadings on those values. Method: In a stepwise procedure, these values are explicated and identified with ethnic groups of rural or urban origin. A relation is postulated of the cultural value profile among them. Specifically, three ethnic groups in Malaysia are studied in their two settlement situations to see whether, from interviews, they express accommodation preferences and hold orientations as predicted. Results: The cultural characteristics of the elderly which facilitate planning of their future accommodation are (a) strong positions on cultural values and (b) subscription to certain values which, from the viewpoint of the accommodation system, come to dominate others and hence can be considered generic to the particular ethnic group or even Malaysian society. Findings: The key operative variables of the accommodation system are preserving face, a desire for harmony, with compliance a third factor. These values have been shown to influence the decisions on housing accommodation, particularly in determining change in accommodation and barrier free spatial forms in the housing environment, and shaping free flowing interaction with the community and choice in housing options. Overview of the Key Points: Cultural value is a new paradigm in determining future planing for housing the elderly. Value orientations essentially promulgate some facilitations within the accommodation system which are being used as parameters to determine three aspects of housing for the elderly: housing environment, physical planning and choices of accommodation. 2009-01-07T15:12:20Z Mohd Yusof, Yusnani http://espace.library.uq.edu.au/view/UQ:71834 2007-08-14T12:23:41Z Barron, P.

Specifically, it compares the learning styles of students studying in Scotland and Australia depending on the year level of study and as such it highlights the learning style preferences displayed by students at different stages of their educational experience. The paper concludes with a discussion regarding the importance of recognising the potential changes in learning style preferences as student's progress in their studies. The paper further concludes with discussion regarding the implications of such changes for academic staff. 2005-12-09T00:00:00Z Barron, Paul E. og Watson, Sandra og McGuire, David http://espace.library.uq.edu.au/view/UQ:160077 This paper discusses social welfare planning for the elderly in the newly industrialized countries, compares it to an industrialized country like Australia, and examines the differences that exist between them. METHOD: The social welfare policy matrix identifies gaps in the provision of health, social welfare, income security, housing and the environment in the newly industrialized countries. The focus of the finding is management-driven and is a definitive source for analyzing the extent of welfare for the elderly or its likely future. RESULTS: There exists a substantial difference between countries like Malaysia, Japan, Singapore and Australia. In Japan, the elderly enjoy comprehensive lifelong health lifestyles under the ÈNew Golden Plani, and in Malaysia ÈLong Term Care Insurancei provides the elderly access to public health care but does not have mandatory care insurance. Welfare through income supports to individuals is available in Australia, while in Malaysia income supports are disbursed to the needy. CONCLUSION: Conceptualizing policy responses to the present and future social welfare needs of the elderly in the newly industrializing countries does not necessarily mirror those of the developed countries. However the gaps essentially provide a possible benchmark to support the formulation of new policies or the adjustments that are needed to ensure that the elderly population in newly industrialized countries live well into their old age. 2009-01-07T15:25:39Z Mohd Yusof, Yusnani http://espace.library.uq.edu.au/view/UQ:104421 2007-08-23T22:22:18Z Gill, T K og Armston, og Phinn, S R og Pailthorpe, B http://espace.library.uq.edu.au/view/UQ:73539 In this paper we proposed a composite depth of penetration (DOP) approach to excluding bottom reflectance in mapping water quality parameters from Landsat thematic mapper (TM) data in the shallow coastal zone of Moreton Bay, Queensland, Australia. Three DOPs were calculated from TM1, TM2 and TM3, in conjunction with bathymetric data, at an accuracy ranging from +/-5% to +/-23%. These depths were used to segment the image into four DOP zones. Sixteen in situ water samples were collected concurrently with the recording of the satellite image. These samples were used to establish regression models for total suspended sediment (TSS) concentration and Secchi depth with respect to a particular DOP zone. Containing identical bands and their transformations for both parameters, the models are linear for TSS concentration, logarithmic for Secchi depth. Based on these models, TSS concentration and Secchi depth were mapped from the satellite image in respective DOP zones. Their mapped patterns are consistent with the in situ observed ones. Spatially, overestimation and underestimation of the parameters are restricted to localised areas but related to the absolute value of the parameters. The mapping was accomplished more accurately using multiple DOP zones than using a single zone in shallower areas. The composite DOP approach enables the mapping to be extended to areas as shallow as <3 m. (C) 2004 Elsevier Inc.

This paper outlines a pedagogical approach devised to encourage learning and critical thinking about climate change. A constructivist approach to teaching and learning is applied to stimulate analysis of potential impacts of climate change on systems familiar to secondary school students in South Australia. The problem-based method guides students through a conceptualisation of the implications of environmental change. Students at Woodcroft College, when given the opportunity to examine the potential climate change impacts on a local coastal ecosystem, found the method to be both challenging and engaging. The exercise concluded with students discussing possible personal behavioural and broader societal responses to reduce the impacts of future climate change. The paper contends that such teaching to support students to become resilient young adults will be vital in a future world of environmental risk. 2008-04-15T13:01:35Z Bardsley, Douglas K. og Bardsley, Annette M. http://espace.library.uq.edu.au/view/UQ:83846 2007-08-14T13:19:47Z Keniger, M.

W. og Jenkins, O. H. og Gum, K. C. og Davis, R. M. http://espace.library.uq.edu.au/view/UQ:34593 Turtle excluder devices (TEDs) are being trialed on a voluntary basis in many Australian prawn (shrimp) trawl fisheries to reduce sea turtle captures. Analysis of TED introductions into shrimp trawl fisheries of the United States provided major insights into why conflicts occurred between shrimpers, conservationists, and government agencies. A conflict over the introduction and subsequent regulation of TEDs occurred because the problem and the solution were perceived differently by the various stakeholders. Attempts to negotiate and mediate the conflict broke down, resulting in litigation against the U.S. government by conservationists and shrimpers. Litigation was not an efficient resolution to the sea turtle-TED-trawl conflict but it appears that litigation was the only remaining path of resolution once the issue became polarized. We review two major Australian trawl fisheries to identify any significant differences in circumstances that may affect TED acceptance. Australian trawl fisheries are structured differently and good communication occurs between industry and researchers. TEDs are being introduced as mature technology. Furthermore, bycatch issues are of increasing concern to all stakeholders. These factors, combined with insights derived from previous conflicts concerning TEDs in the United Stares, increase the possibilities that TEDs will be introduced to Australian fishers with better acceptance. 2007-08-13T10:17:48Z Tucker, AD og Robins, JB og McPhee, DP http://espace.library.uq.edu.au/view/UQ:97444 2007-08-24T01:15:30Z Wills, B.

Previous attempts to assess sustainable development for fisheries have mostly failed because the methods have been too restrictive, often attempting to develop a single set of indicators. In 2000, all the fishery agencies and major stakeholder groups in Australia supported the development of a National ESD Framework. This initiative resulted in a practical system being generated through the results of a series of case studies and stakeholder workshops. The Australian National ESD Framework divides ESD into eight major components within the three main categories of ecological well-being, human well-being and ability to contribute: Four main steps are used to complete an ESD report for a fishery: (1) identify relevant issues, (2) prioritise these using risk assessment, (3) complete appropriately detailed reports on each issue and (4) compile the material into a report. The tools to assist this process are now available and have been used to generate reports for many Australian fisheries. (C) 2004 Elsevier B.V. All rights reserved. 2007-08-15T06:34:07Z Fletcher, W.

A framework was developed to provide an objective approach to selecting remotely sensed data sets for specific environmental monitoring problems. Preliminary applications of the framework have provided successful approaches for monitoring disturbed and restored wetlands in southern California. 2007-08-13T10:50:26Z Phinn, SR http://espace.library.uq.edu.au/view/UQ:36007 This paper presents a brief review of the relative merits of norm-referenced and criterion-referenced assessment of undergraduate students' written work. Acknowledging that there are both positive and negative aspects of criterion referencing, a generic framework for such assessment of undergraduate essays is presented. It comprises criteria and standards (organised by 'dimensions of achievement', i.e. content, process, affect and skills), proficiency standards for English language and communication competence, and cartographic and graphic skills. Problems of implementation include the size and complexity of the framework and the need to interpret and clarify the criteria and standards for students. 2007-08-13T11:28:05Z Neil, D.

A random sample of 205 site locations provided the basis for determining trends in land use. Trends in vegetation clearing were determined using sequential aerial photography for the sample sites, revealing a steady rate averaging nearly 1% of the region per annum over 41 years. This measure of sustained clearing over a large region is higher than recently published clearing rates from South America. Land types have been selectively cleared with over 90% of the Acacia on clay land type having been cleared. A land-holder questionnaire pertaining to the random sites yielded a response rate of 71% and provided information on vegetation clearing, ploughing, tree killing (ring-barking or tree poisoning), and fire frequency, season and intensity. The land-holder responses were compared with independent data sources where possible and revealed no mis-information. However, land-holders may have been marginally less likely to respond if the sample area had been cleared, although this effect was not statistically significant. Ploughing and tree killing are variable depending on land type, but the former has affected about 40% of the Acacia on clay land type, effectively eliminating options for natural regrowth. The proportion of decade-site combinations that were reported as having no fires increased from 22% in the 1950s to an average of 42% for subsequent decades, although the reporting of more than one fire per decade has been relatively constant through the study period. The reporting of at least one fire per decade varies from 46% for the Acacia on sand land type to 77% for the Eucalypt on sand land type for decade-site combinations. Fires are more intense when associated with clearing than in uncleared vegetation, but the proportion of cool and hot fires is relatively constant between land types in uncleared vegetation. Nearly all fires reported were either in spring or summer and this seasonally restricted regime is probably at variance with Aboriginal fire regimes. This study describes the rapid transformation of central Queensland. This has yielded substantially increased agricultural production but may also result in a range of negative impacts and these are discussed. 2009-01-29T10:17:23Z Fensham, Roderick J. og Fairfax, Russell J. http://espace.library.uq.edu.au/view/UQ:136395 A late Quaternary marine palynological record from the Ocean Drilling Program (ODP) site 820, adjacent to the humid tropics region of northeastern Australia, has demonstrated marked variation in orbital scale cyclicity, and also trends associated with both climate and human impact. However, some uncertainties in interpretation have resulted from concerns about the records chronology and continuity. Here we present, for the first time, the complete palynological data from detailed analysis of the top 67 m of sediment and examine it in relation to the marine isotope sequence from the core. It is proposed that the record is relatively continuous through the last 250,000 years although the latter part of oxygen isotope stage (OIS) 5, as well OIS 4 may be missing. Despite the variation on orbital scales, most palynological changes are not in phase with those from the marine isotope record suggesting a lack of direct Milankovitch forcing on vegetation. This lack of correspondence combined with major trends towards more open and sclerophyllous vegetation in association with increased burning supports a previous proposal that major control is being exercised by El Nino-Southern Oscillation variability whose influence may have been initiated by changes in oceanic circulation in the region within the mid Pleistocene. The lack of impact on the distribution of complex rainforest suggests that increased climate variability did not involve an overall decrease in total precipitation. (C) 2007 Elsevier B.V.
