The project intends to develop tools to accurate predict fountain flows. Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of turbulent fountains and negatively buoyant jets. The project aims to conduct an investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, and to assess the accuracy of the commonly used integral models and test the effect of the use of more accurate entrainment relations. This may have a range of applications – enabling better prediction of environmental impacts, reduction of the adverse effects of the discharge of pollutants, and reduction in energy consumption in building ventilation and other industrial applications.Read moreRead less

How isolated is Antarctica? Assessing past and present plant colonisations. The project aims to assess how biologically isolated Antarctica is by discovering how, when and where natural colonisations of the continent have occurred. The research will focus on mosses, the dominant plant group in the Antarctic. genomic tools will be combined with environmental, spatial, and ecological data to assess mechanisms and directions of dispersal to and around Antarctica, and to predict areas most likely to ....How isolated is Antarctica? Assessing past and present plant colonisations. The project aims to assess how biologically isolated Antarctica is by discovering how, when and where natural colonisations of the continent have occurred. The research will focus on mosses, the dominant plant group in the Antarctic. genomic tools will be combined with environmental, spatial, and ecological data to assess mechanisms and directions of dispersal to and around Antarctica, and to predict areas most likely to be colonised in the future. This will help understand the processes underpinning the evolution and diversity of Antarctic species, and the vulnerability and adaptability of Antarctic ecosystems. Read moreRead less

Evolutionary history and conservation of an iconic Australian plant group. This project aims to strengthen biodiversity conservation using evolutionary biology. By using new DNA sequencing technologies the project aims to reconstruct the evolutionary history of the diverse and ecologically important plant family Proteaceae. This will be used to discover how past environmental changes have produced the biodiversity we see today, and forecast likely future changes to biodiversity under expected r ....Evolutionary history and conservation of an iconic Australian plant group. This project aims to strengthen biodiversity conservation using evolutionary biology. By using new DNA sequencing technologies the project aims to reconstruct the evolutionary history of the diverse and ecologically important plant family Proteaceae. This will be used to discover how past environmental changes have produced the biodiversity we see today, and forecast likely future changes to biodiversity under expected rapid environmental change. The key outcome will be a new methodology for a predictive, forward-looking conservation science that accounts explicitly for the dynamic, evolving nature of biodiversity. The key benefit will be a more robust scientific basis for strategic allocation of limited conservation resources.Read moreRead less
Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeologi ....Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeological data to show how losses varied in space, how population sizes changed, and how species attributes such as rarity and body size related to loss. The world of mammals has become more homogeneous as biodiversity has declined. The challenge is to show how that happened across space and time.

Unraveling the mystery of the Plain of Jars, Laos. Since their discovery in the 1930s, the mysterious collections of giant stone jars scattered throughout central Laos have remained one of the great prehistoric puzzles of south-east (SE) Asia. It is thought that the jars represent the mortuary remains of an extensive and powerful Iron Age culture. This project seeks to determine the true nature of these sites, which date to a dynamic period of increasing complexity in SE Asia (c.500BCE-500CE). T ....Unraveling the mystery of the Plain of Jars, Laos. Since their discovery in the 1930s, the mysterious collections of giant stone jars scattered throughout central Laos have remained one of the great prehistoric puzzles of south-east (SE) Asia. It is thought that the jars represent the mortuary remains of an extensive and powerful Iron Age culture. This project seeks to determine the true nature of these sites, which date to a dynamic period of increasing complexity in SE Asia (c.500BCE-500CE). The project entails extensive reconnaissance, precision mapping, archaeological excavation and analysis of associated burial material. Using a suite of cutting-edge archaeological technologies, it is expected to have far-reaching benefits for archaeology, science, Laos and World Heritage.Read moreRead less
Long range toxic metal pollution in Australia and the Southern Ocean. This project aims to investigate how environmental change and human activities since industrialisation have impacted toxic metal transport and deposition on the south coast of Australia, Tasmania and Southern Ocean islands.

This project aims to investigate how environmental change and human activities since industrialisation have impacted toxic metal transport and deposition on the south coast of Australia, Tasmania and Southern Ocean islands. This project expects to fill gaps in understanding of the global mercury cycle using a state-of-the-art multidisciplinary methodology including the role of sea salt aerosols and hemispheric-scale wind patterns . Anticipated outcomes involve a novel palaeo-atmospheric model that can be applied in other parts of the world. This should provide significant benefits, such as science-based evidence to ratify the Minamata Convention on Mercury and guide new regulations to reduce environmental/health risks from metal pollution.

This project aims to conduct an archaeological survey of Vanuatu. One of archaeology's most significant contributions is providing models for the emergence of cultural diversity through time. Vanuatu is one of the most diverse regions on Earth. The southern islands were an important hub in early settlement and long-term inter-island interactions of Island Melanesia. Yet little is known about the origins of cultural contacts and diversity in the area. A major archaeological survey of the Polynesian outliers Futuna and Aniwa and neighbouring islands Tanna and Aneityum would greatly improve our knowledge of settlement patterns, long-distance exchange, and cross-cultural interaction in the region, from initial Lapita settlement 3000 years ago through to the arrival of Christian missionaries in the 1860s.Read moreRead less

This project aims to understand flying-fox movement ecology from individual navigation through to population redistribution. Understanding movement across spatiotemporal scales is a goal of movement research. Grey-headed flying-foxes are mobile, and advances in tracking technology make them ideal for studying movement across scales. This project will determine how flying foxes navigate, and integrate this with drivers of their movement to understand their movement ecology by using methods that integrate experimental manipulation with telemetry, Doppler radar and analytical techniques. This is expected to develop much-needed management strategies that incorporate an understanding of movement.Read moreRead less
