Abstract:
Squat lobsters have only recently been recorded from the Macquarie Ridge, which extends south between New Zealand and Antarctica. Among these, Uroptychus insignis (Henderson, 1885) was recorded for the first time outside the western Indian Ocean, exhibiting only subtle morphological differences. Reexamination of the Macquarie Ridge and Indian Ocean specimens attributed to U. insignis using morphological and molecular data revealed the Macquarie Ridge form to represent a separate species. Subtle but consistent morphological differences are evident and partial CO1 sequence data indicates that the specimens collected on Macquarie Ridge differ from those collected in the Indian Ocean by more than 7%. The Macquarie Ridge species is described herein as Uroptychus macquariae n.sp. Subtle morphological differences between the new species and U. insignis are discussed.

Abstract:
Macquarie perch, Macquaria austalasica, is an endangered species endemic to southern Australia whose distribution is highly fragmented and continues to decline. Key threatening processes include habitat destruction, dams and weirs, overfishing and interactions with introduced species. Here, we examined the responses of small and large Macquarie perch to two native predators and to the introduced redfin perch, Perca fluviatilis. Our results showed that Macquarie perch generally avoided large-bodied native predators but was attracted to small-bodied native predators. Responses to large and small redfin perch lay between these two extremes, suggesting that the Macquarie perch does treat these foreign fish as potential threats. Macquarie perch relied on both visual and chemical cues to identify predators, although its response tended to be stronger when exposed to visual cues. The results suggest that Macquarie perch has the capacity to recognise and respond to invasive species in a threat-sensitive manner, which has positive implications for the conservation management of the species.

Abstract:
The Macquarie perch (Macquaria australasica) is a threatened fish species that inhabits rivers and impoundments in south-eastern Australia. Previous studies have shown that Macquarie perch in impoundments exhibit synchronised upstream spawning migrations to shallow, fast-flowing habitats in the lower reaches of inflowing streams. There has been little study of movement behaviours of entirely riverine populations of Macquarie perch despite this being the species’ natural habitat. Here, radio-telemetry is used to test the hypothesis that riverine populations exhibit synchronised migrations during the spawning season. Thirty Macquarie perch in the Yarra River, Victoria, a translocated population outside of the species’ natural range, were radio-tagged before the late spring–early summer spawning season and their movements followed over a 10-month period (May 2011 to February 2012). Tagged fish typically occupied restricted reaches of stream (<450 m). Sixteen of the fish undertook occasional upstream or downstream movements (~250–1000 m) away from their usual locations, particularly associated with large flow variations during the spawning season. There was no evidence of synchronised migratory behaviour or movement of multiple fish to specific locations or habitats during the spawning season. Whilst further research over more years is needed to comprehensively document the spawning-related behaviours of riverine Macquarie perch, our study demonstrates that management of riverine populations of this threatened species cannot necessarily be based on the model of spawning behaviour developed for lacustrine populations.

Abstract:
Understanding species-reproduction dynamics is vital for the management of riverine fish. Information on the spawning ecology of the endangered Australian Macquarie perch (Macquaria australasica) is based largely on data gathered from lacustrine populations, with uncertainty on the applicability such data has for managing riverine populations. The current study presents a first description of spawning patterns of two riverine populations of Macquarie perch in Victoria, Australia, using egg counts recorded across multiple sites and periods within the species core spawning window. Spawning intensity was highly variable between study sites, with 96 and 82% of eggs collected from a single site in the King Parrot Creek and Yarra River respectively. We also found a strong positive association between spawning and water temperature. Our results provide an important account of spatio-temporal spawning patterns of riverine Macquarie perch populations and lend some support for the transfer of information from lacustrine populations (as demonstrated by spawning habitat and temperature association). Although the spatial and temporal constraints of the present study must be considered, the results provide opportunity for further testing of the environmental effects, and management options aimed at enhancing spawning of this endangered species.

Abstract:
Management interventions are often needed to facilitate the recovery of ecosystems affected as a result of human alteration. Population-level monitoring is often central to evaluating the effectiveness of specific on-ground actions. In the present study, we assessed the response of a remnant population of the endangered Macquarie perch (Macquaria australasica) to the construction of a rock ramp fishway on the Cotter River, Australia, over a 7-year period. Prior to fishway construction, this obligate riverine spawner had been previously confined to Cotter Reservoir and six kilometres of stream by a raised road-crossing. Surveys conducted in the 2 years following fishway completion failed to detect Macquarie perch upstream of the fishway. Subsequent surveys (6–7 years post-fishway completion) detected Macquarie perch up to 12 km upstream of the fishway. The number and distribution of smaller-sized individuals (0+ (<100-mm total length (TL) and 1+ (100- to >150-mm TL)) suggests that individuals found upstream of the fishway are resident stream fish and not fish that have migrated from known downstream spawning areas. The success of the fishway has been timely because enlargement of a downstream reservoir will inundate four kilometres of river and destroy the majority of spawning sites of this species downstream of the fishway in the Cotter River.

Full text
Abstract:
In response to concern that excessive macroalgal growth and accumulation was occurring in some inshore areas of Lake Macquarie, the distribution, abundance and seasonality of macroalgae was investigated in relation to nutrient input and power station cooling water. Macroalgal dry weight biomass was measured at ten sites on a monthly basis for two years, with an analysis of community structure conducted using Multi-Dimensional Scaling. The macroalgal community in Lake Macquarie was typical of those found in other New South Wales coastal lagoons, exhibiting considerable spatial and temporal variation. A close similarity was observed in macroalgal community structure at sites affected by urban nutrient input, these being characterised by a high biomass often attributable to only one or two species. These nuisance macroalgae were mostly green algae, which were almost entirely absent from other sites. Biomass at sites affected by urban nutrient input was generally within the range documented for eutrophic estuaries elsewhere. Analysis of macroalgal community structure showed no evidence of large-scale changes macroalgal communities attributable to the effects of power station cooling water except within 500m of the outfall. At sites affected by a 1-2??C temperature increase, community structure and the magnitude of the biomass were similar to sites deemed as being relatively free of human impact. A reduction in species diversity occurred only within the immediate discharge zone, where water temperatures were approximately 6??C above ambient temperatures. Excessive growth of nuisance macroalgal species was not observed at any of the sites influenced by power station cooling water. There were no distinct patterns in seasonality of macroalgal growth in this study, though the greatest biomass appeared to occur in spring. The irregular temporal variation in macroalgal growth suggests that the most significant factors affecting growth occur on a time scale of weeks to months. It is therefore likely nutrient input to the nearshore through surface runoff is an important influence on the distribution and abundance of macroalgae in Lake Macquarie. This emphasises the need to reduce nitrogen and phosphorus input from urban sources in Lake management.

Abstract:
In February 2005, riots involving local youth against police erupted in Macquarie Fields following the deaths of two local young men who were in a stolen vehicle being pursued by police. The riots at the time were dismissed by the serving Government, the Opposition, NSWP police management and sections of the media, as merely a handful of young thugs behaving poorly. However, subsequent media coverage, political debate recorded in Hansard, academic literature and the findings of the Standing Committee on Social Issues (2006) revealed discontent amongst some residents concerning the behavior, attitudes and inconsistent actions of Macquarie Fields police. This study, through interviews conducted with government and non-government service providers servicing the Macquarie Fields community and interviews/observations conducted with Macquarie Fields police participants, examined perceptions held by Macquarie Fields police concerning their accountability and partnership with the community. It sought to discover whether police-community programs implemented following the 2005 riots impacted upon police perceptions of accountability to the community and led to improved relations between police and community. Findings indicated that despite the attempts of Government and police management to improve relations between Macquarie Fields police and community, the relationship remained problematic. Police participants were found to hold variable notions of accountability and partnership towards the community. This combined negatively with the primary crime reduction strategy of ‘stopping searching and moving on’ local youth socializing in public places, which was reported by community service respondents as being conducted by younger inexperienced police in an adversarial manner.

Abstract:
The need for an increase in the learning of foreign languages in primary schools in Australia was noted by the Senate Standing Committee on Education and the Arts (Report on a National Language Policy, 1984, Recommendation 78, p230). The introduction of the Japanese language program at Macquarie Primary School, ACT, in 1984, was a response to this need, combined with the expressed wish of the local community. Within this program it was decided that an unpublished curriculum developed and used in the ACT by a native speaker of Japanese, would be trialled. The purpose of this study, within a Master of Education degree, was to evaluate Book 1 of this curriculum, and the process by which it was implemented at the school, during the first year of operation of the program. The framework around which the evaluation was organised was Sanders and Cunningham's (1973) Structure for Formative Evaluation in Product Development. The evaluation sought to answer five questions which focussed on the validity, appropriateness and consistency of the broad goals of the program, and the extent of achievement of those goals by the students; the effect of the implementation of the program on school organisation; unexpected outcomes of the program; and revisions and modifications which were necessary to the program as the curriculum was trialled. A number of data gathering techniques was used to obtain the information required to answer these questions. The results of this study suggest that the curriculum being trialled was based on an eclectic approach to the teaching of a foreign language (Prator, 1980; Bell, 1981), selecting from various theories and methodologies, components deemed appropriate for primary age students in their first year of Japanese. The study also provided evidence that, after one year's participation in the Japanese program all children were, to an extent, achieving both broad goals of the program. There was some evidence however, that achievement of the goals was mediated by several learner characteristics, the most influential of these falling into the broad category of 'attitude'. It was discovered also, that the introduction of such a program into an already crowded school curriculum affected aspects of organisation within the school, and that all the outcomes of the program were not necessarily planned, or expected. Finally, certain changes, both organisational and to the curriculum, were made and implemented during the 'formative interim evaluation' stage. The conclusions of this thesis are offered at two levels: conclusions concerning the evaluation process itself, and those arising from the teaching of Japanese to primary age students.

Abstract:
ABSTRACT This work examined the role of micro-organisms in the biogeochemical cycling of selenium within the benthic ecosystem of Lake Macquarie, a coastal lake in New South Wales with a history of anthropogenic heavy metal contamination. Certain micro-organisms possess the ability to oxidise or reduce selenium (Fleming and Alexander, 1973; Doran and Alexander, 1977), and microbial volatilisation of selenium from contaminated sediments and soils utilising naturally-occurring microflora has been shown in overseas research (Thompson-Eagle and Frankenberger, 1992) to be a potentially effective remediation strategy. In examining the impact of micro-organisms upon the oxidation state of selenium in Lake Macquarie sediments, this work also investigated and characterised selenium (and heavy metal) concentrations, speciation and geochemical phase associations (an indicator of potential bioavailability) in the sediments. Seven distinct bacterial species indigenous to Lake Macquarie were identified in this work with the ability to reduce selenium as selenite to elemental selenium, and selenium as selenate to organic forms of selenium, including volatile methylated selenium compounds. Metabolic parameters calculated for these organisms compared favourably with those reported in the literature by other researchers. Mixed populations of sediment micro-organisms were also isolated and studied in this work for their selenite and selenate reduction abilities. Total reduction of added selenite at levels up to 100 mg/L was recorded for a number of the organisms studied in this work. A maximum specific uptake rate for selenite of 3040 mgSe(IV).(gcells)-1.(h)-1 for one isolate (Shewanella putrefaciens) was determined, exceeding rates reported in the literature by other authors. Use of the indigenous micro-organisms from Lake Macquarie for the bioremediation of selenium containing waste streams was also examined in this work and selenium reduction in an immobilised cell reactor was demonstrated with such organisms. Concentrations, speciation, sediment core profiles and geochemical phase associations for selenium were determined for sediment samples collected at a variety of sites throughout Lake Macquarie and from Wyee Creek, a selenium-impacted fluvial input to the lake. The maximum concentration of selenium obtained in this work for the lake proper was 4.04 mg/kg, considerably lower than values reported over a decade ago (Batley, 1987) but consistent with reported reductions of selenium input into the lake from the lead-zinc smelter. Selective extraction methodology (Tessier et al. and BCR methods) studied geochemical phase association of selenium in Lake Macquarie sediments and found up to 44% of selenium was in bioavailable forms. Of interest and environmental concern was levels of selenium found in sediments of Wyee Creek, which previously received overflows from the ash dam associated with the Vales Point Power Station. Sediment selenium levels of up to 300 mg/kg were determined for this creek. These were an order of magnitude or more greater than those recorded for the lake itself and are of concern as to the potential impact on benthic organisms and those animals, including humans, who consume them. While this work can only provide a 'snapshot' of conditions within Lake Macquarie at the time of the sampling events recorded herein, it does make several important contributions to the understanding of selenium biogeochemistry in Lake Macquarie. These include: presentation of the hypothesis that selenium levels in surficial sediments being deposited in the north of the lake have decreased in recent years as a result of selenium reduction measures undertaken by the lead-zinc smelter; determination that up to 44% of selenium in surficial sediments from the lake is associated with sediment phases in which selenium has the potential to become remobilized and hence possibly bioavailable; and documentation of selenium concentrations in Wyee Creek, identifying the area as having selenium concentrations an order of magnitude or more greater than the lake itself. Concerning the role played by microorganisms in the biogeochemical cycling of selenium in Lake Macquarie, this work has: identified individual isolated and mixed cultures of bacteria that can reduce selenium as selenite to lower oxidation states; identified individual isolated and mixed cultures of bacteria that can reduce selenium as selenate to lower oxidation states; identified volatile methylated selenium compounds in the headspace gases of microorganisms reducing selenate; determined Minimum Inhibitory Concentrations for selenate and selenite for organisms isolated from Lake Macquarie; identified casein hydrolysate as a preferred carbon source for selenium reducing microorganisms from Lake Macquarie; and demonstrated that bioremediation of selenium contaminated waste streams using indigenous organisms from Lake Macquarie is feasible on the laboratory scale. Further research areas suggested by this work include: additional investigations of elevated selenium levels in Wyee Creek sediments; determination of the role of microbes in in-situ selenium reduction; and optimisation of selenium biotreatment/bioremediation of selenium-containing waste streams and sediments. In summary, this work, in rejecting the null hypothesis that the oxidation states of selenium in sediments from Lake Macquarie, NSW, are independent of microbial activity and accepting the alternate hypothesis that these oxidation states are not independent of microbial activity, contributes to the understanding of the role of microorganisms in the biogeochemical cycling of selenium, having applicability to both the specific ecosystem of Lake Macquarie, NSW, and also to selenium cycling in the environment in general. In addition, this work has identified selenium contamination in Wyee Creek, one of the fluvial inputs to Lake Macquarie, which was previously been undocumented in the literature and which may pose significant potential risk to humans and the ecosystem due to sediment selenium levels one or more orders of magnitude higher than those recorded in the lake itself. Finally, this work has also identified a number of microorganisms indigenous to Lake Macquarie with the ability to reduce selenium from toxic, mobile forms to less toxic, immobile or volatile forms, and these organisms have been shown to have the potential for use in treatment of selenium contaminated waste streams and also in the bioremediation of selenium-contaminated sediments.

Abstract:
Scyphozoans of the genus Cassiopea are notable for their unusual benthic habitat of lying upside-down with their exumbrella resting on the substrate and oral arms facing upwards, resulting in their common name “upside-down jellyfish”. Cassiopea are model examples of an invasive species that have been historically confused because of their taxonomic ambiguity and can have significant economic and environmental consequences as their blooms are known to impact fisheries, tourism, and trophic structures. Cassiopea were first reported in temperate Lake Macquarie, New South Wales, in 2017, though historically these jellyfish have a more northern tropical distribution in Eastern Australia. This project aims to provide baseline information on the identification and presence of Cassiopea in Lake Macquarie and inform potential management strategies. This study used a genetic analysis to confirm two species of Cassiopea are expanding their range down the east coast of Australia, with a focus on C. xamachana, the species occurring in Lake Macquarie. A morphometric analysis identified the features that can be used to distinguish these species, and these results combined with the genetic analysis confirmed that C. maremetens, described in 2010 from southern Queensland, is a junior synonym of C. xamachana. Additionally, the results from this study confirm that Cassiopea abundance peaks during Austral Autumn and Winter, before experiencing a population crash in August. This appears to be controlled by temperature and turbidity, but their density and distribution is expected to increase with climate change. Additionally, no polyps have been found in the area and only females have been recorded, suggesting there was only one invasion event into Lake Macquarie, and since then, the polyps have been asexually reproducing. As a result, long-term monitoring is recommended and this study demonstrates that drones are a precise and efficient method for doing this.

Abstract:
Declaring in the late 1950s that Sydney City was in much need of a car free civic square, Professor Denis Winston, Australia’s first chair in town and country planning at the University of Sydney, was echoing a commonly held view on how to reconfigure the city for a modern-day citizen. Queen’s Square, at the intersection of Macquarie Street and Hyde Park, first conceived in 1810 by Governor Lachlan Macquarie, remained incomplete until 1978 when it was developed as a pedestrian only plaza by the NSW Government Architect under a different set of urban intentions. By relocating the traffic bound statue of Queen Victoria (1888) onto the plaza and demolishing the old Supreme Court complex (1827), so that nearby St James’ Church (1824) could becoming freestanding alongside a new multi-storey Commonwealth Supreme Court building (1975), by the Sydney-based practise of McConnel Smith and Johnson, the civic and social ambition of this pedestrian space was assured. Now somewhat overlooked in the history of Sydney’s modern civic spaces, the adjustment in the design of this square during the 1960s translated the reformed urban design agenda communicated in CIAM 8, the heart of the city (1952), a post-war treatise developed and promoted by the international architect and polemicist, Josep Lluis Sert. This paper examines the completion of Queen’s Square in 1978. Along with the symbolic role of the project, that is, to provide a plaza as a social instrument in humanising the modern-day city, this project also acknowledged the city’s colonial settlement monuments beside a new law court complex; and in a curious twist in fate, involving curtailing the extent of the proposed plaza so that the colonial Supreme Court was retained, the completion of Queen’s Square became ultra – civic.
