Our research, which focuses on the world's most recently discovered, fossil-rich amber deposit will significantly increase this value. In addition to discovery of hundreds of stunningly-well preserved fossil organisms, analysis of trapped bubbles of ancient air will enable us to reconstruct their prehistoric environment. This should improve ability to anticipate biotic responses to future climate change. The amber industry globally contributes to national wealth. Increasing understanding about the geology and palaeontology of this amber deposit will maximise commercial and scientific benefits to the nation.Read moreRead less
Overturning the Ediacara biota: community structure of the oldest animal ecosystems. The first systematic excavation of serial fossil beds of South Australia's famous Ediacara biota will lead to an integrated study of the oldest diverse macroscopic assemblages of life on Earth. Once the preservational and biological components of the record have been separated, Ediacaran fossil beds can be treated as 'snap-shots? of benthic marine communities. This will enable the use of palaeoecological tools t ....Overturning the Ediacara biota: community structure of the oldest animal ecosystems. The first systematic excavation of serial fossil beds of South Australia's famous Ediacara biota will lead to an integrated study of the oldest diverse macroscopic assemblages of life on Earth. Once the preservational and biological components of the record have been separated, Ediacaran fossil beds can be treated as 'snap-shots? of benthic marine communities. This will enable the use of palaeoecological tools to determine which if any of these Precambrian fossils were members of animal groups that heralded the Cambrian explosion of animal life.Read moreRead less
Environmental change in northern Cenozoic Australia: a multidisciplinary approach. The Intergovernmental Panel on Climate Change (IPCC) warned that by 2020 to 2050, Australia will suffer significant biodiversity loss and water shortages. Our research will document and date the evolution of Australia's biota through three cycles of climate change over the last 25 million years to quantify and thereby better anticipate the nature and dimension of threats facing our natural and cultural communities ....Environmental change in northern Cenozoic Australia: a multidisciplinary approach. The Intergovernmental Panel on Climate Change (IPCC) warned that by 2020 to 2050, Australia will suffer significant biodiversity loss and water shortages. Our research will document and date the evolution of Australia's biota through three cycles of climate change over the last 25 million years to quantify and thereby better anticipate the nature and dimension of threats facing our natural and cultural communities. We will develop innovative techniques to date prehistoric biotic and climatic events and, using a range of tracers, characterize ancient environments and groundwater. This project will assist rural and regional Australia through education and job creation in geotourism and natural resource interpretation and provide a mechanism to combat generational skill shortage.Read moreRead less
The evolution of Australian rainforest faunas and the implications of continuing climate change. Australia's rainforest animals and ecosystems have been evolving for millions of years yet we routinely use only the last 200 years to assess changes that will affect their future - far too short a time interval to distinguish short-term perturbations from long-term trends in lineage health or community response. Our multidisciplinary team proposes to learn from 55 million years of response to rainfa ....The evolution of Australian rainforest faunas and the implications of continuing climate change. Australia's rainforest animals and ecosystems have been evolving for millions of years yet we routinely use only the last 200 years to assess changes that will affect their future - far too short a time interval to distinguish short-term perturbations from long-term trends in lineage health or community response. Our multidisciplinary team proposes to learn from 55 million years of response to rainfall and other climate change documented by the spectacular national, natural treasures in the fossil deposits of Tingamarra, Riversleigh and Rockhampton, to assess probable impacts of future environmental change and inform development of effective, long-term conservation strategies for rainforest communities.

Survival stategies and dynamics of stromatolite-associated microbial populations. Biogenic stromatolites are formed by the accretion of carbonates and entrapment of sediments by benthic cyanobacteria, algae and other microorganisms. Stromatolites have been present on Earth for more than three billion years and the biogeochemical processes involved in their formation are indicators of the earliest life on this planet. The applicant proposes to study, at the level of molecular genetics, the divers ....Survival stategies and dynamics of stromatolite-associated microbial populations. Biogenic stromatolites are formed by the accretion of carbonates and entrapment of sediments by benthic cyanobacteria, algae and other microorganisms. Stromatolites have been present on Earth for more than three billion years and the biogeochemical processes involved in their formation are indicators of the earliest life on this planet. The applicant proposes to study, at the level of molecular genetics, the diversity of stromatolite-associated microorganisms. The defined microbial populations will be correlated with the prevailing environmental conditions to elucidate the effect of biological and physical factors in determining stromatolite structure.Read moreRead less
Links between marine biotic evolution and carbonate platform and petroleum reservoir development in the South China sea. This project will aim to discover the major environmental controls over the historical development of the high biodiversity of Indo-Pacific coral reefs. By investigating fossils from rocky outcrops we will enhance the ability of petroleum companies to predict the occurrence of hydrocarbons in sub-surface reef limestones.
Time frame for the evolution of Australia's extraordinary mammals. This Project will refine a national biostratigraphic framework integrating growing understanding about the history of Australia's unique mammals, climate change and geological events. Increasing precision in correlating Australia's phylogenetic, palaeoecological and palaeoclimatological events will clarify how these act synergistically to change environments and biodiversity. Increased precision in the biostratigraphic framework ....Time frame for the evolution of Australia's extraordinary mammals. This Project will refine a national biostratigraphic framework integrating growing understanding about the history of Australia's unique mammals, climate change and geological events. Increasing precision in correlating Australia's phylogenetic, palaeoecological and palaeoclimatological events will clarify how these act synergistically to change environments and biodiversity. Increased precision in the biostratigraphic framework will also serve evolutionary genetics which needs age data to calculate molecular rates of divergence, economic geologists needing to know the age of Cainozoic sediments, biologists trying to understand the origins and nature of biodiversity and conservationists using divergence dates and relative branch lengths to help determine conservation priorities.

Unlocking archives of faunal dispersal and extinction: the key to reconstructing palaeoenvironmental change in Southeast Asia. The influence of environmental change on faunal populations is a pressing issue for Australian communities in environmentally sensitive areas. This will be addressed by documenting how fauna (and humans) in Southeast Asia, our nearest neighbours, responded to environmental challenges. Revealing when humans dispersed through the region and how they adapted will contribute ....Unlocking archives of faunal dispersal and extinction: the key to reconstructing palaeoenvironmental change in Southeast Asia. The influence of environmental change on faunal populations is a pressing issue for Australian communities in environmentally sensitive areas. This will be addressed by documenting how fauna (and humans) in Southeast Asia, our nearest neighbours, responded to environmental challenges. Revealing when humans dispersed through the region and how they adapted will contribute to our understanding of the cultural heritage of Australia's indigenous settlers. This project will develop established Indonesian collaborations, encourage new collaborations with Chinese, Thai, English and Dutch researchers to promote Australian research on a world stage, and pioneer new dating methodologies to enhance Australia's place at the forefront of geochronology.Read moreRead less
Developing a geomorphological framework to underpin management decision-making on the Great Barrier Reef. The paucity of data on coral reef growth histories inhibits attempts to integrate regional reef growth data into coral reef management - despite the major influence on habitat type and diversity. This project will gather such data for one region of the Great Barrier Reef, and develop such datasets to support future reef management decision-making.
