Abstract:
So as to assess how emerging science and new tools can be applied to study multiple stressors at a large (ecosystem) scale and to facilitate greater integration of approaches among different scientific disciplines, a workshop was organised on 10–12 September 2014 at the Sydney Institute of Marine Sciences, Sydney, Australia. The present paper discusses the limitations of the current risk-assessment approaches and how multiple stressors at large scales can be better evaluated in ecological risk assessments to inform the development of more efficient and preventive management policies based on adaptive management in the future. A future risk-assessment paradigm that overcomes these limitations is presented. This paradigm includes cultural and ecological protection goals, the development of ecological scenarios, the establishment of the relevant interactions among species, potential sources of stressors, their interactions and the development of cause–effect models. It is envisaged that this will be achievable through a greater integration of approaches among different scientific disciplines and through the application of new and emerging tools such as 'big data', ecological modelling and the incorporation of ecosystem service endpoints.

Abstract:
As global research into recreational fishing gains momentum due to the pursuit’s biological, social and economic impacts, information on regional and temporal patterns of recreational exploitation will continue to enable objective assessment and development of management initiatives for exploited species. This paper demonstrates the utility of offsite survey methods in assessing spatial and temporal differences in recorded catches from a large, diffuse and heterogenous coastal recreational fishery. Using the estuarine recreational fishery that operates along the coast of New South Wales, Australia as a case study, survey data was employed to quantify annual (June 2013-May 2014) state-wide estuarine catch. Generalized linear mixed effects models were then applied to expanded catch estimates from surveyed households to examine the influence of zone and season on the kept and released numbers of snapper (Pagrus auratus), dusky flathead (Platycephalus fuscus) and bream (Acanthopagrus spp. complex comprised of A. butcheri, A. australis and their hybrids). For kept bream, significant differential seasonal effects were observed in all regions except the Mid-South Coast. For released bream, numbers were greatest in Sydney and during Summer and Winter. For kept snapper, the greatest harvest was recorded in the Mid-South Coast but season had no effect. Differential seasonal effects were found in each zone for released snapper. For kept dusky flathead, the greatest numbers were recorded in Sydney and the Mid-South Coast but season had no effect. We conclude by assessing some current spatial and temporal management initiatives in light of the uncovered patterns of recreational catch and consider the implications of these patterns in terms of future ecosystem-based management recommendations aimed at achieving ecological, social and economic sustainability in fisheries.

Abstract:
In order to assess how emerging science and new tools can be applied to study multiple stressors on a large (ecosystem) scale and to facilitate greater integration of approaches among different scientific disciplines, a workshop was held on 10–12 September 2014 at the Sydney Institute of Marine Sciences, Sydney, Australia. This workshop aimed to explore the potential offered by new approaches to characterise stressor regimes, to explore stressor-response relationships among biota, to design better early-warning systems and to develop smart tools to support sustainable management of human activities, through more efficient regulation. In this paper we highlight the key issues regarding biological coverage, the complexity of multiply stressed environments, and our inability to predict the biological effects under such scenarios. To address these challenges, we provide an extension of the current Environmental Risk Assessment framework. Underpinning this extension is the harnessing of environmental-genomic data, which has the capacity to provide a broader view of diversity, and to express the ramifications of multiple stressors across multiple levels of biological organisation. We continue to consider how these and other emerging data sources may be combined and analysed using new statistical approaches for disentangling the effects of multiple stressors.

Abstract:
The treatment of stormwater using surface constructed wetlands has become common in the last decades. However, the use of constructed wetlands for stormwater management has not been thoroughly evaluated in their capacity to treat microbial loads. The case studies presented in this paper are situated at Lake Macquarie, a large estuarine lagoon located approximately 150 km north of Sydney, Australia. To protect the lake ecosystem from the impact of increasing urban development, the local Council constructed numerous stormwater quality improvement devices (SQIDs) at selected locations. The SQIDs typically consisted of trash racks, gross pollutant traps and surface constructed wetlands. To evaluate the effectiveness of three of these devices in reducing faecal contamination, water samples were collected for faecal coliforms (FC) during and following rainfall at inlets and outlets of the structures. Results indicated one of the SQIDs as the most efficient for bacterial reduction, while the other two provided low or non reduction of FC. Results also illustrated dependence of bacteria reduction on flow conditions. Comparison of devices suggested that hydraulic residence times and other design parameters strongly influenced the capacity of each device to reduce FC counts during different weather conditions.

Abstract:
SUMMARYReconstructing the environmental history of protected areas permits an empirically-based assessment of the conservation values ascribed to these sites. Ideally, this long-term view can contribute to evidence-based management policy that is both ecologically ‘realistic’ and pragmatically feasible. Lachlan Nature Reserve, a protected wetland in Centennial Park, Sydney, is claimed to be the final remnant of early and pre-European swamplands that were once extensive in the area, and the site is thus considered to have indigenous cultural and natural conservation significance. This study uses palynological techniques to reconstruct vegetation communities at the Reserve from the late Holocene to the present in order to assess whether these values adequately reflect the history, character and development of the site. The findings indicate that the modern site flora is a modified Melaleuca quinquenervia low forest assemblage formed in response to aggregated anthropogenic disturbance since colonial settlement. This assemblage replaces an Epacris-dominated heath-swampland community that was extirpated in the mid-20th century. These results emphasize the value of long-term studies in contributing to a realistic management policy that explicitly reflects the normative basis of conservation, and values the influence of past land-uses on contemporary protected ecosystems.

Abstract:
Although the Sydney Catchment Authority (SCA) largely controls the quality of water entering the Sydney catchments, it has limited jurisdiction over the majority of activities undertaken on private land, where much of the non-point source pollution originates. The current governance model reflects a traditional ‘command and control’, government-centred philosophy limiting the economic opportunities for landholders. Using six case studies from other jurisdictions we explore the potential for market-based schemes to better enable the SCA to meet its statutory objectives. A contemporary payments for watershed services scheme could better address issues of non-point pollution in more efficient and fairer ways than the present model. Under such a scheme, the SCA would rely more upon negotiated service arrangements pursuing a ‘least cost of supply’ for a defined water quality output, with the costs of these arrangements being reflected in the price of water to consumers. Funds are likely to be applied more strategically to secure water quality outcomes at the least public and private cost while maximizing the value of non-water ecological services from the same lands. These findings are relevant and can be applied to many other drinking water catchments within Australian and other jurisdictions.

Abstract:
Mixed-use development is increasingly popular in land use planning and zoning, fostering a combination of residential, commercial, and cultural uses into one space. However, there is a lack of understanding of the vertical mix office space within a high-rise commercial building and the dynamics of the industry mix between buildings. This paper examines the spatiotemporal patterns of industry mix between and within office buildings in Sydney CBD from 2006 to 2017, using the data obtained from the City of Sydney floor space and employment surveys. This is the first study that identifies the dynamics of an industrial ecosystem in central Sydney, which has transformed to homophily land blocks, with increasing vertically heterogeneous office buildings, over the past decade. In addition, the study found that the significant clustering of anchor tenants, such as finances, hospitalities, and knowledge-based industries, are apparent.

Abstract:
Development of low-lying land affected by high water table in saline and sodic soils and local swampy areas remains a challenge for the local government, developers, and other regulators. The development control plan for a proposed residential or commercial subdivision in such a site in Penrith, Sydney, Australia, states that the drainage and stormwater management systems within and across the site should be improved and proposed buildings should be constructed on the ground higher than the 100-year flood level. This paper presents the results of engineering geological and geotechnical investigations for the proposed subdivision. The subsurface profile at the site comprises alluvial deposits underlain by residual soil, which in turn is underlain by shale and sandstone. In the eastern portion of the site, the alluvial deposits comprise a sequence of clay, sand and gravel, and in the western portion they contain a succession of clean sand and gravel. The alluvium in the eastern portion of the site is saline whereas it is generally non-saline in the western portion. All saline soils are sodic and most non saline ones are non-sodic. This paper discusses the suitability of on-site soils for use in a structural fill and impermeable clay liner as well as the management of saline and dispersive soils.

Abstract:
This study has contributed to the development of the reference condition approach in disturbed landscapes. The reference condition approach has been an important development for the bioassessment of aquatic ecosystems by providing a practical tool for the accurate assessment of river condition. The selection of appropriate reference sites is critical to the success of the predictive model in terms of being able to distinguish between natural variation in biota and the effects of human disturbance. Capturing natural variability and explaining it is a key difference between the reference condition approach and other study designs (e.g. before/after/control/impact). Natural disturbances such as drought or bushfire can significantly alter the ecological condition of streams, and although the ecological condition of streams affected by natural drought or bushfire is part of the natural cycle, this natural variation of the ecological condition is rarely incorporated into many study designs because of a mismatch in time scales. Human disturbance has also significantly altered the condition of landscapes through the development of agriculture and urbanisation. In urban or agricultural landscapes it can be impossible to locate streams that have not been modified by human activity for use as a reference condition. This study looked at the effects of natural disturbance on the reference condition, in terms of the way natural disturbance affects the prediction of stream condition and also the incorporation of the condition of streams experiencing natural disturbance into a predictive model. Additionally this study identified an alternative benchmark for modified landscapes based on the presence of good management practices for river protection, and tested this benchmark for the assessment of streams impacted by urbanisation. Drought and bushfire regularly disturb aquatic ecosystems in Australia, and affected reference sites in the ACT and South Coast region of New South Wales in 2002 and 2003. Drought and bushfire conditions affected macroinvertebrates and environmental variables across these streams, and the majority of sites were assessed as significantly impaired using regional AUSRIVAS (AUstralian RIVers Assessment System) models. This indicated the existing reference conditions for these regions had not incorporated the ecological conditions of reference sites suffering these natural disturbances. Many of the environmental variables used to predict the condition of streams were also affected by drought or bushfire. The changes to environmental variables affected how sites were assessed in models, but the overall assessment was not significantly changed from the initial assessment that drought or bushfire had significantly impaired the ecological condition. To reduce potential assessment errors associated with changes to predictor variables an attempt was made to construct new models with changeable variables excluded. However, it was not possible to completely exclude these types of variables, and subsequent models were no better than the original models in terms of changes to predictor variables affecting the generation of expected taxa lists. The changes to environmental variables did not affect the actual assessment of site condition because although group membership probabilities were changed the probabilities of taxon occurrence did not change significantly. The different reference site groups all contained some common taxa that occurred at most sites and even when group probabilities changed this did not change the probability of these taxa occurring at a test site. For regional models, such as the ACT or NSW South Coast, changes to predictor variables may not significantly affect the assessment of site condition. Incorporating reference sites under drought conditions into a predictive model was an effective way of discriminating the effects of drought from human disturbance. The model only provided two different ecological conditions, a single drought measurement and a single non-drought measurement, so the model did not fully encompass the potential natural variability. The model has value as a starting point and was effective in distinguishing sites affected by human disturbance from sites affected by drought. Good Management Practice (GMP) for river protection is any intervention that minimises human impact on stream condition. Urban sites protected by GMP were used as an alternative benchmark to a minimally impacted reference condition. The criteria used to select reference sites were not sufficiently robust to detect a significant benefit of GMP on physical or chemical characteristics of protected sites, compared to sites without GMP. In general however, the physical and chemical condition of GMP sites was better than sites without GMP and there were significant differences in macroinvertebrate assemblages of GMP and non-GMP sites. A refinement to the site selection process is proposed to include a specific assessment of GMP effectiveness for the protection it is designed to provide. This will substantially improve the robustness of a GMP benchmark and provide a clearer picture of the factors controlling biota in urban streams protected by GMP. The GMP benchmark was developed into a predictive model for the assessment of urban stream health, and in terms of the assessment of test site condition, it did not differ significantly from a model using minimally impacted sites. The purpose of the GMP benchmark was to provide an alternative reference condition for the assessment of stream health in modified landscapes when minimally impacted sites are unavailable or provide an unattainable benchmark. The GMP reference condition as an alternative can provide an attainable and realistic benchmark. The development and application of the suggested site selection protocol will improve the robustness of the GMP benchmark and better account for natural variation in the biota and physical characteristics of the sites used to determine the reference condition.

Abstract:
Nitrogen fixation is no longer considered to be a minor factor of the nitrogen cycle in oceanic ecosystems. Recent geochemical and biological efforts have led to a significant increase in the estimated input of nitrogen to marine ecosystems by biological fixation, while molecular studies have increased our knowledge of the number and diversity of nitrogen fixers known to be active in the ocean. Although Trichodesmium spp. have long been viewed as the primary marine nitrogen fixers, recent efforts have shown that various members of the picoplankton community are also actively involved in nitrogen fixation. The relative abundance of different nitrogen fixers is an important ecosystem parameter since nitrogen fixers may differ significantly in their physiology, life history and ecology. Here we combine rate measurements and stable isotope natural abundance measurements to constrain the impact of N2 fixation in the waters north of Australia. Samples were collected in the Coral, Arafura, and East Timor Seas, thus spanning three distinct hydrographic regions. Our data show that Trichodesmium has a significant influence on the stable nitrogen isotope ratios of particulate and zooplankton biomass and suggest that Trichodesmium is a significant source of nitrogen for the pelagic ecosystem. Based on stable carbon isotope ratios, it is also likely that the pathways are indirect and nitrogen fixed by Trichodesmium enters the higher trophic levels via decomposition as dissolved organic and inorganic nitrogen. Picocyanobacteria showed high diazotrophic activity at some stations, but unlike Trichodesmium, their N2 fixation rate was not reflected in the stable N isotope ratios of particulate and zooplankton biomass. Our results suggest an important N contribution to biomass by diazotrophs in the Coral Sea, Arafura Sea and East Timor Sea.

Abstract:
Anthropogenic impacts such as fishing and eutrophication are significant challenges to the sustainable management of aquatic ecosystems. This study used two ecosystem modelling techniques to investigate the effects of fishing and eutrophication on aquatic ecosystems in Western Australia. Firstly, a qualitative modelling technique called ‘loop analysis’ or ‘qualitative modelling’ was used to characterise the dynamics of the seagrass ecosystem in Shark Bay, Western Australia (Chapter 2). A qualitative model based on differential equations, was developed to represent the dynamics of the seagrass ecosystem, particularly interactions among tiger sharks, megafauna (e.g. dugongs), and megafauna prey (Fig. 2.2). Although the model structure generated some uncertainty about model predictions and model stability, it was possible to assess the stability of the model and to determine the response signs of model variables by applying data and magnifying loops. Qualitative modelling analyses indicated a strong top-down control by tiger sharks and suggested that this controlling effect occurred in four stages. A step-by-step increase in tiger sharks (States 1 and 2) led to a habitat shift by the megafauna out of seagrass meadows and into safer, deeper channel habitat. A step-by-step decrease in tiger shark numbers led to the megafauna returning to seagrass meadows, leading to a decrease of megafauna prey in this habitat (steps 3 and 4). Thus, tiger sharks influenced the use of seagrass habitats by megafauna species through direct and behaviourally mediated impacts. Further, megafauna responses to tiger shark predation risk established alternating predation pressure on different prey groups within seagrass habitats. Curiously, despite the fact that only some megafauna species (e.g. dugongs) are major components of diet of the adult tiger sharks, the perceived predation risk created by the high abundance of of tiger sharks in summer appears sufficient to cause megafauna species to leave (or under-utilise) feeding habitats in seagrass meadows. Thus, the modelling results suggest that the abundance of tiger sharks exerts an important top-down, regulatory influence on the other ecosystem components. This regulatory system has the potential to become imbalanced if there is a decrease in the abundance of adult tiger sharks in Shark Bay, as has occurred tiger shark populations in other areas worldwide. Targeting of tiger sharks by fishers in the waters of Northern Australia and Indonesia has increased steadily during the last years and impact the tiger shark stock in Shark Bay if, as has been hypothesized, there is single common stock. A qualitative trophic model suggested that the activities of recreational fishermen within Shark Bay reduce prey availability for juvenile tiger sharks, an impact which might adversely affect the tiger shark population and, thus, the dynamics of this seagrass ecosystem. Evidence of the ecological importance of tiger sharks and the potential impact of a population decline emphasises the need to sustain the tiger shark population in Shark Bay. In the second part of this study, a quantitative modelling technique, Ecopath with Ecosim and Ecospace, was applied to the ecosystem of the Peel-Harvey Estuary, Western Australia. A key impact on this ecosystem is the the Dawesville Channel, an artificial entrance channel was constructed in the mid-1990s to increase the flushing and reduce nutrient concentrations in the estuary. Ecopath was used to analyse the impact of the Dawesville Channel on the estuarine ecosystem. A large dataset was collected for model development, a process that uncovered significant data gaps (e.g. missing data on detritus pool and dietary information and indicated important areas for further research (Chapter 3). Two identical Ecopath models (comprising 30 living functional groups) were otherwise developed for the Peel-Harvey Estuary to describe the state of the ecosystem before (‘pre DC’) and after (‘post DC’) the opening of the Dawesville Channel (Chapter 4). Modelling found that, in addition to changes in the community structure of plants, fish and invertebrates, the entire ecosystem of the Peel-Harvey Estuary has declined drastically in total biomass since the opening of the Dawesville Channel, as has the biomass at each trophic level and in the size of flows between the functional groups. Changes in flows and transfer efficiencies suggested a change in the functioning of the ecosystem in which consumption has become a more important and more efficient flow since the opening of the channel. Analysis of network and system statistics indicated that food web structure had also changed, with more linkages in the ‘post DC’ model and thus a more web-like structure than in the ‘pre DC’ model. Modelling also identified changes in cycling processes and suggested that the ecosystem in the ‘post DC’ model was not able to keep carbon within the system, even though: (i) the food web has developed more linkages and (ii) with less primary production and less cycling, the size of the ecosystem has decreased drastically since the channel opening. Overall, the results of the Ecopath modelling indicated that the Dawesville Channel has markedly impacted the features, functioning and services of the Peel-Harvey Estuary (Chapter 4). Several indices were applied that suggested that both the ‘pre DC’ and the ‘post DC’ models were highly immature. Ecopath was also applied to investigate the impact of the Dawesville Channel on ecosystem services. Ecopath modelling indicated that all ecosystem services had declined, such as provisioning services (catches), regulating services (CO2-Fixation) and supporting services (nutrient cycling, primary production and biodiversity). Unfortunately, it was not possible to locate data relating to cultural services (tourism) for the ‘pre DC’ model. To support the reliability of the Ecopath and Ecosim predictions, model uncertainty and the sensitivity of the parameter settings were assessed in detail (Chapter 5). Overall, the results of this analysis indicated that the parameter settings for the ‘pre DC and ‘post DC’ models were robust and did not lead to uncertainties regarding modelling results and predictions. However, the vulnerability settings are crucial for Ecosim and Ecospace and need to be treated with caution. Ecosim was applied to identify: 1) the impact and effectiveness of the selective reduction of different primary producers and 2) the impacts of fishing on target and non-target species on the ecosystem model (Chapter 6). The application of Ecosim requires fitting a model to time series data; for this study, the sourcing and fitting of time-series data indicated the importance and uncertainty of vulnerability settings. Three categories of vulnerabilities were identified: (a) vulnerabilities that did not have any effect on time series fitting (category 1); (b) interactions in which the lowest sums of squares occurred at low vulnerability settings (v=1 or 2, category 2); and settings that had a drastic impact on model fitting (category 3). The Ecosim simulations indicated that fishing affected almost all functional groups in the model, not just the target species. The recreational fishing sector also had a very strong impact on many functional groups, particularly Blue Swimmer Crabs and other invertebrate groups like bivalves and gastropods. The commercial fishing sector affected functional groups less than the recreational sector, but affected a range of estuarine fish groups including non-target fish species. Thus, the results of this study suggest that it may be not advisable to close those fleets completely as some aspects of the estuary ecosystem appear to benefit from increasing fishing pressure. Some fish groups and some target species responded positively to the closure of certain fleets, while others – particularly waterbirds and other top predators – did not (Table 6.8). Ecosim analyses highlighted the need for more data to ensure sustainable management, but suggested that the coexistence of fleets might be a better solution for sustaining catches and group biomasses in the future. Ecosim modelling indicated that selective plant removal is a reasonable management tool for this estuary. However, nutrient reduction and, thus, the permanent reduction of microscopic algae appears to be more ecologically and economically worthwhile (Fig. 6.12). Removing aquatic plant groups showed no significant longterm change in biomasses and the magnitude of short-term effects was much higher than for long-term effects. The Ecosim simulations demonstrated that only a permanent reduction in microscopic algae led to a reduction in total biomass. Reducing phytoplankton might be worthwhile because, although blooms of Nodularia spumigena no longer occur in the estuary because the salinities are too high (Huber, 1985), the estuary now contains several phytoplankton species (e.g. Heterosigma akashiwo) that cause blooms in other ecosystems (Guiry & Guiry, 2010). While the effects of phytoplankton blooms on the ecosystem depend on the size (i.e. the biomass) of the bloom, even blooms that only double the biomass of microscopic algae can have drastic long-term effects. This study supports the conclusion that a reduction in phytoplankton through management of nutrient input in the estuarine catchment represents the only ecological and economical management scenario that provides long-term sustainability for this ecosystem (Chapter 6). Ecospace modelling represents biomass dynamics over two-dimensional space and time. For this study, a model with fours habitats (shallow mud, deep sand, rocks and plant habitat) was developed. By applying Ecospace, the effects of reducing plant habitat and the effectiveness of two Marine Protected Areas were investigated, with specific consideration of waterbirds (Chapter 7). The Ecospace simulations suggested that waterbirds and piscivorous waterbirds were impacted by fishing and would benefit slightly from an introduction of a MPA, in particular a MPA at Point Grey. Further, the results of this Ecospace scenario indicated that waterbirds would profit from the reduction of plant habitat, whereas piscivorous waterbirds showed a small decline in biomass after removal of aquatic plants. Under the current fishing effort, the total biomass of the system and of the fish community increased. Thus, while the major prey groups of piscivorous waterbirds increased in biomass, but piscivorous waterbirds did not benefit from increased prey biomasses in the model, presumably because of the competition for fish. Ecospace modelling indicated that the catches would also increase drastically and, thus, that piscivorous waterbirds were in direct competition with the fishing sectors and other piscivorous predators (e.g. dolphins and sharks) and were out-competed for fish. The modelling suggest that the sustainable management of the fishing sectors is essential for bird conservation. A MPA at Peel Inlet led to lower catches under the current fishing scenario and catches declined even further under lower fishing effort. In contrast, after introducing a MPA at Point Grey, the total catch only declined when the fishing effort was lessened. The Ecospace simulations indicated that an MPA at Point Grey increased the biomasses of functional groups and target species and also raised the total biomass of the system; however, these effects strongly depend on fisheries management (Chapter 7). Overall, the qualitative and quantitative modelling methods applied in this study improved our understanding of the dynamics and functioning of the Shark Bay and Peel-Harvey ecosystems (Chapter 8). Both approaches produced robust and reliable results. If precise quantitative predictions are required for a management scenario, Ecopath with Ecosim is the appropriate method to choose, as this approach can deliver detailed changes in biomass and catches. In contrast, qualitative modelling only indicates the direction of change, which might not always satisfy management needs. However, qualitative models are the ideal method when management decisions have to be made fast and when a detailed data set of the ecosystem is not available.

Abstract:
[Truncated abstract] Selection of priority areas for Marine Park conservation is often compromised by the lack of comprehensive biodiversity data and the resources and expertise necessary to gain this information directly by sampling. One cost effective alternative is the use of species groups or indicator species as surrogates for total biodiversity. However use of these surrogates requires an ecological understanding of how they reflect biodiversity gradients. A framework for unravelling these relationships has been suggested that involves relating species biodiversity to different and competing ecological models using appropriate statistical analysis. I use this framework to explore coral species biodiversity over a range of environmental gradients encompassing the North West Shelf of Australia and the Great Barrier Reef in North East Australia. ... I assessed physiological responses of corals to physical factors to corroborate crossshelf patterns in species biodiversity. Finally, I investigated to what extent coral cooccurrence based species groups (or guilds) can be used as surrogates for total coral biodiversity. The major findings of this thesis were: i) coral biodiversity along cross-shelf environments was highly correlated to specific gradients of abiotic reef conditions; ii) larval modelling indicates the potential for significant connectivity across continentalshelf environments such that differences in species distribution are not simply as a result of self seeding. iii) similar correlative patterns were demonstrated for coral species that occur along comparable abiotic gradients in reef areas of both Eastern and Western Australia, suggesting a causal relationship between the physical environment and coral biodiversity; iv) coral physiological parameters measured using lipid fractions independently corroborated the hypothesis that there is a biological basis for observed coral distributions; v) reef coral communities are not highly structured across abiotic physical gradients and biodiversity across the shelf increases as conditions become suitable for a wider range of species; vi) total coral biodiversity can be estimated very accurately (within r2 values ranging from 0.75 to 0.90) using a small number (15-30) of optimally chosen indictor species using the randomForest statistical method. These results suggest coral biodiversity over cross-shelf environments conforms most closely to the

Abstract:
A global shift away from diets dominated by meat, dairy and eggs to mainly plant-based diets is as necessary in mitigating anthropogenic climate change as the shift away from fossil fuels. Yet a large awareness gap exists about animal agriculture's contribution to greenhouse gas emissions. Recent studies in Australia and the United States show this issue is represented in less than 1 percent of all newspaper articles about climate change. This chapter examines the opportunities and barriers in addressing the livestock sector's impact on climate change. Policy recommendations in the literature are compared with the responses of governments, industry and the NGO sector. Australia's unique socioeconomic and cultural ties to livestock production and the consumption of animal products represent a significant barrier to demand-side mitigation. An analysis of newspaper articles mentioning animal agriculture's link to climate change in The Sydney Morning Herald between 2006 and 2014 provides insights into the facilitation and shaping of public awareness on the issue to date. The findings can inform strategies to increase future media coverage and encourage a more engaged discourse on demand-side mitigation.

Abstract:
Megaprojects are an essential part in social, economic, and environmental developments and they attract a consortium of stakeholders ranging from governments, communities, international consumers, and suppliers. Hence, stakeholder management in these projects contributes significantly to projects’ success and sustainability. The research project, on which this paper is based on, aims to identify key challenges and propose suitable strategies to manage stakeholders in megaprojects for better sustainability outcomes. In achieving this aim, the research re-viewed key concepts related to project stakeholder management in megaprojects, explored sustainable challenges and analysed appropriate stakeholder management strategies through a secondary review of two major case studies of megaprojects in Sydney, Australia. The key findings discovered that the main factors influencing stakeholders were related to social, economic and environmental impacts of the project and, the need for managing them through proactive stakeholder management strategies. The implications of this research guide project managers on managing stakeholders on megaprojects and inform on possible challenges and solutions to achieve sustainable outcomes. Further research could extend and replicate on other case studies in different contexts and project types.

Abstract:
A delocalized international team of Graduate and Undergraduate students conceive, design, implement, and operate a 3 meter wingspan aircraft with the intent to investigate numerous new ‘green’ aircraft technologies. The project, known as Hyperion, teaches essential systems engineering skills through long-distance design collaborations with multidisciplinary teams of engineering students located around the world. Project partners are the University of Colorado at Boulder, USA, the University of Sydney, Australia, and the University of Stuttgart, Germany. The teams on three continents are distributed 8 hours apart; students can relay select work daily so that progress can “Follow The Sun (FTS).” As a result three workdays are packaged in one 24 hour period. The student teams operate as a single, independent entity; structuring themselves as a simulated industry operation. Thus, project management and systems engineering principles are learned through a real-world design and deliver experience. The project also teaches delocalized manufacturing: select components are manufactured by each team and integrated both in Stuttgart and Colorado, giving the students an opportunity to learn multifaceted design for manufacturing. The project incubated many problems which lead to mitigation techniques for global collaboration as well as generating a better educated workforce to enter modern industry.
