Establishing research programs with Pacific neighbours benefits Australia's relations with Pacific Island countries generally. This project applies novel research methods to understanding human adaptations to long-term environmental and climatic fluctuations. It will address the National Research Priority goal of responding to climate variability by advancing our understanding of recent climate change in the Australia/Pacific region. It will show that Australian researchers can play a significant role in understanding the spread of humans across the Pacific, and the environmental adaptations required by populations in resource depleted environments. It will increase collaboration between research institutions focusing on the Australia/Pacific region.Read moreRead less
Sediment-derived scenarios of wetland status and change, the Lower River Murray, SA. River Murray wetlands changed early in European settlement so the pre-impact conditions are invisible to managers relying on anecdote or monitoring. Baseline conditions of wetlands can be derived from ecological archives preserved in sediments. Fossil diatom assemblages, reflective of past water quality, and other fossils, will be exhumed from sediment sequences to reconstruct wetland conditions. The integration ....Sediment-derived scenarios of wetland status and change, the Lower River Murray, SA. River Murray wetlands changed early in European settlement so the pre-impact conditions are invisible to managers relying on anecdote or monitoring. Baseline conditions of wetlands can be derived from ecological archives preserved in sediments. Fossil diatom assemblages, reflective of past water quality, and other fossils, will be exhumed from sediment sequences to reconstruct wetland conditions. The integration of multiple indicators of the past will generate graphic re-enactments of natural wetland dynamics. These will provide a vision for community and government on-ground managers enabling them to perceive appropriate targets for wetland state and so generate measures to work towards sustainable conditions.Read moreRead less
Retrospective ecological character assessment for a review of Ramsar status of The Coorong, SA. Integrated analyses of the chemical and biological remains contained in the sediments of the Coorong will provide for a reconstruction of ecological change and variability over the last several thousand years. Detailed analyses of the recent sediments will measure how the condition of the Coorong has departed from this natural background and so provide an audit of human impact on the last wetland in t ....Retrospective ecological character assessment for a review of Ramsar status of The Coorong, SA. Integrated analyses of the chemical and biological remains contained in the sediments of the Coorong will provide for a reconstruction of ecological change and variability over the last several thousand years. Detailed analyses of the recent sediments will measure how the condition of the Coorong has departed from this natural background and so provide an audit of human impact on the last wetland in the Murray darling Basin. This evidence will directly inform the determination of the ecological character of this Ramsar listed, national ecological asset and steer its management for a sustainable future. Read moreRead less

Understanding the complex inter-relationship between humans and the natural environment is of critical importance. The use of geo-scientific techniques to interpret historical environmental records provides a useful tool for obtaining this knowledge. Using the medieval city of Angkor, Cambodia, as a case study, the proposed research will employ well-established analytical techniques in a new and innovative manner to reconstruct environmental change and cultural adaptation. This research, the first of its kind undertaken at Angkor, will revolutionise our understanding of this World Heritage site, and contribute to a better understanding of the synergy between human culture and its environmental context.Read moreRead less
Using ancient fish ear bones to overcome the shifting baseline syndrome in freshwater fish populations. Chemical tracers in fish ear bones from 5,500 years ago through to modern times will provide information on changes in fish ecology over centuries and identify why freshwater fish populations have declined. Outcomes will provide knowledge of how fish populations would react to altered fishing pressure and restoration of environments.
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

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
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 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
