Reconstructing past population dynamics to understand human and climatic impacts in prehistory. More than 100 species have become extinct since humans first colonised Australia, and over 1000 are considered threatened. This research will determine the factors most strongly governing the interaction between humans and native fauna in Australia over the last 46 millennia. Our approach is powerful and novel because it will effectively draw together multidisciplinary evidence on natural resource exp ....Reconstructing past population dynamics to understand human and climatic impacts in prehistory. More than 100 species have become extinct since humans first colonised Australia, and over 1000 are considered threatened. This research will determine the factors most strongly governing the interaction between humans and native fauna in Australia over the last 46 millennia. Our approach is powerful and novel because it will effectively draw together multidisciplinary evidence on natural resource exploitation and habitat alteration by ancient people, and the influence of dramatic climatic shifts on the Australian biota. Information on past biological responses to environmental change is critical to properly contextualising the current impact, and long-term consequences of, threats such as global warming, habitat loss and invasive species.Read moreRead less
Sustainable development in southwestern Victoria: construction of a baseline palaeoecological record for assessment of past and future human-environment interactions. A detailed, continuous, sediment-based, multi-proxy palaeoenvironment record, will be constructed to contribute to the goals of the innovative, community-based Lake Condah Sustainability Development Project that are informed management and heritage listing of the Mt Eccles lava flow region, southwestern Victoria. The record, coveri ....Sustainable development in southwestern Victoria: construction of a baseline palaeoecological record for assessment of past and future human-environment interactions. A detailed, continuous, sediment-based, multi-proxy palaeoenvironment record, will be constructed to contribute to the goals of the innovative, community-based Lake Condah Sustainability Development Project that are informed management and heritage listing of the Mt Eccles lava flow region, southwestern Victoria. The record, covering at least the last 20,000 years, is designed to (a) provide a dated framework for understanding past human-environment relationships, especially the development of a unique Aboriginal complex hunter-gatherer society based on aquaculture, (b) an historical basis for fire management of a nationally important vegetation community and (c) the provision of a palaeoclimate record of global significance.Read moreRead less
Understanding the early phases of Neolithic dispersal in the western Pacific. The project investigates the transition of mainland Asian cultures to a world of islands from 6000-3500 years ago by an archaeological and palaeoenvironmental study of near-Asian islands including the Philippines and Taiwan. This transition is the formative process that saw island colonisation extend out into the Pacific and Indian Oceans in subsequent millennia, and the project aims to build on earlier archaeological ....Understanding the early phases of Neolithic dispersal in the western Pacific. The project investigates the transition of mainland Asian cultures to a world of islands from 6000-3500 years ago by an archaeological and palaeoenvironmental study of near-Asian islands including the Philippines and Taiwan. This transition is the formative process that saw island colonisation extend out into the Pacific and Indian Oceans in subsequent millennia, and the project aims to build on earlier archaeological work by taking a colonisation approach that assesses resource richness and other environmental forces on the populations. Outcomes include a new and more detailed account of neolithic expansion including accounts of settlement pattern, subsistence development and environmental relationships.Read moreRead less
Long-term natural ecological consequences of disturbance on coral reefs: the benthic foraminifera perspective. The tropical coastline of Australia encompasses world-renowned coral reefs (Great Barrier Reef and Ningaloo Marine Park). Even these reefs are not pristine and are increasingly susceptible to disturbance from human impact. The long-term ecological effects of disturbance on reef communities cannot be experimentally determined; but natural experiments from the fossil record provide mech ....Long-term natural ecological consequences of disturbance on coral reefs: the benthic foraminifera perspective. The tropical coastline of Australia encompasses world-renowned coral reefs (Great Barrier Reef and Ningaloo Marine Park). Even these reefs are not pristine and are increasingly susceptible to disturbance from human impact. The long-term ecological effects of disturbance on reef communities cannot be experimentally determined; but natural experiments from the fossil record provide mechanisms to ensure that managers of Australia's reefs have critical information on how past disturbance frequency and intensity has affected coral reef communities. This information will help ensure the continuation of ecosystem goods and services from Australia's high diversity coral reefs.Read moreRead less
The role of natural selection in macroevolution: a case study examining convergence of form and function in marine predator guilds. Darwin's theory of evolution natural selection is one of the most successful in the history of science and provides the framework for modern biology: however, areas of debate or uncertainty are often misinterpreted by non-scientists as indication of fundamental flaws in the theory. New 'hi-tech' tools provide the opportunity to re-examine these areas, and also to de ....The role of natural selection in macroevolution: a case study examining convergence of form and function in marine predator guilds. Darwin's theory of evolution natural selection is one of the most successful in the history of science and provides the framework for modern biology: however, areas of debate or uncertainty are often misinterpreted by non-scientists as indication of fundamental flaws in the theory. New 'hi-tech' tools provide the opportunity to re-examine these areas, and also to demonstrate the process of science to the public. The new tool is Computational Biomechanics, the future of studying biological form, and this project will further develop the leading role of Australian research in this technology which has applications for palaeontology, environmental management, medical science, and the next generation of engineering using 'biomaterials'.Read moreRead less
Human Impact and Environmental Change in the Lower Yangtze Delta, China. Based upon a combination of sediment-based proxies of palaeoenvironmental conditions this project attempts to link existing models of geomorphological and climatic variability for the Yangtze Delta to cultural changes evident in archaeological and historical records. The Yangtze valley was the home of agriculture in Asia and hence for the beginnings of village life and Chinese culture. The delta region has prograded over 10 ....Human Impact and Environmental Change in the Lower Yangtze Delta, China. Based upon a combination of sediment-based proxies of palaeoenvironmental conditions this project attempts to link existing models of geomorphological and climatic variability for the Yangtze Delta to cultural changes evident in archaeological and historical records. The Yangtze valley was the home of agriculture in Asia and hence for the beginnings of village life and Chinese culture. The delta region has prograded over 100 km since the early Holocene and there is a well- preserved succession of Neolithic and modern cultures across its surface. The project investigates the relative impact of Holocene river migration, sealevel and climate change on societies, and also the relative impact of societies on vegetation, eutrophication and erosion while the region was converted to an anthropogenic landscape. The results will enable models of human-environmental interactions to be compared with those developed for
Europe, Africa, Australia and the Middle East.Read moreRead less
Quantifying the effects of western colonisation on Great Barrier Reef molluscan communities. Dead shells provide a record of the pre-colonisation Great Barrier Reef (GBR) ecosystem. Using this record this research will determine what the GBR looked like before James Cook and the first fleet arrived in Australia. This study will also sample living molluscs to quantify the current state of these communities. Together these data will provide environment managers and stakeholders with the first quan ....Quantifying the effects of western colonisation on Great Barrier Reef molluscan communities. Dead shells provide a record of the pre-colonisation Great Barrier Reef (GBR) ecosystem. Using this record this research will determine what the GBR looked like before James Cook and the first fleet arrived in Australia. This study will also sample living molluscs to quantify the current state of these communities. Together these data will provide environment managers and stakeholders with the first quantitative estimates of human impacts on this world heritage ecosystem. This project will address the questions: Do protected areas return to a pre-colonial state or do they represent another non-natural state? What type of management scheme results in communities most similar to the pre-colonial state?Read moreRead less
