Beyond migration and diffusion: The prehistoric mobility of people & ideas. The project plans to build on the strength of current collaborations between archaeologists and geochemists to ask novel questions about the movement of people and ideas in prehistory. The project plans to examine spatial and temporal patterns in population mobility to clarify their relationship with the appearance of new and exotic materials, technologies and practices. The project focuses on the ways in which the movem ....Beyond migration and diffusion: The prehistoric mobility of people & ideas. The project plans to build on the strength of current collaborations between archaeologists and geochemists to ask novel questions about the movement of people and ideas in prehistory. The project plans to examine spatial and temporal patterns in population mobility to clarify their relationship with the appearance of new and exotic materials, technologies and practices. The project focuses on the ways in which the movement of individuals and groups of people is both an instigator and a response to sociocultural change, using both key European and Pacific Island examples, to help build a comparative archaeology of phenomena of rapid social and economic change, with pertinence to general theories of innovation and adoption.Read moreRead less
East Asian Monsoon response to periods of abrupt global change. This proposal aims to investigate the response of the East Asian Monsoon to abrupt climatic change, under baseline states of both warm and cool climate. The research is significant as it utilises unique, precisely dated sediments from Japan, and novel approaches to quantifying spatial and temporal climate patterns. The research will improve understanding of the nature and causes of decadal-scale changes in monsoon precipitation, wit ....East Asian Monsoon response to periods of abrupt global change. This proposal aims to investigate the response of the East Asian Monsoon to abrupt climatic change, under baseline states of both warm and cool climate. The research is significant as it utilises unique, precisely dated sediments from Japan, and novel approaches to quantifying spatial and temporal climate patterns. The research will improve understanding of the nature and causes of decadal-scale changes in monsoon precipitation, with relevance for constraining the trajectory of the future monsoon, and the risks of prolonged drought and flood. The findings will benefit the Asian people, for whom the monsoon has major economic, social and environmental importance. In turn, this will benefit Australia, via economic and climatic ties to Asia.Read moreRead less
Were abrupt changes in the Precambrian global carbon cycle the trigger for animal appearance and radiation on Earth? The origin of complex life and the properties that allow that life to be sustained on this planet are recorded within the geologic record. This project will reveal the role that severe perturbations of the global carbon cycle and climate had in triggering the step-wise change to animal life after billions of years of only single cell organisms.
Palaeo-vegetation, biodiversity and early human dispersal though island Southeast Asia. This study will use newly developed and fully validated isotope techniques to obtain robustly dated proxy records of vegetation change from the thick deposits of cave guano that occur extensively throughout island Southeast Asia (Sundaland). This project will test the hypothesis that during the Last Glacial Period, there was a substantial contraction of the rainforest towards the equator into refugia. This le ....Palaeo-vegetation, biodiversity and early human dispersal though island Southeast Asia. This study will use newly developed and fully validated isotope techniques to obtain robustly dated proxy records of vegetation change from the thick deposits of cave guano that occur extensively throughout island Southeast Asia (Sundaland). This project will test the hypothesis that during the Last Glacial Period, there was a substantial contraction of the rainforest towards the equator into refugia. This led to the development of an open ‘savannah corridor’ connecting savanna north and south of the equator. The project will shed new light on the palaeoclimatology of the region and provide a major contribution to explaining modern biogeographic patterns across Sundaland, as well as the trajectories of early human dispersal through the region.Read moreRead less
