Late-Glacial and Holocene environmental variability of southern South America
To predict future climate change and vegetation scenarios, one must first understand the processes and mechanisms that have driven past changes in a region. Climate changes within the Holocene (c. 20-10 k yr before present (BP)) is of particular interest due to the differences in climate scenarios in the Southern and Northern hemispheres.
This research aims to further our understanding of climate change (and subsequent vegetation change and fire history) in Southern South America – an area where previous research is sparse and often criticised. The research will utilise high resolution analyses of sediment cores to investigate the timing and pattern of shifts in vegetation ecotones and the frequency and regimes of fire in the region. Phylogeography techniques will also be employed to investigate the post-glacier spread of trees.
It is anticipated that this research will contribute to a wider understanding of the vegetation and fire history in the region and it will assess the extent to which climate has driven major changes in the environment.
