Transformation of vegetation by big herbivores, from the Pleistocene to now. The project aims to provide a coherent understanding of the effects of extinct and extant large herbivores on ecosystems over space and time. The structure and distribution of vegetation types is determined not only by climate and soils, but also by the impacts of herbivores and fire as consumers of plant biomass. Recent research has shown how fire shapes the large-scale distribution of vegetation types, but we do not h ....Transformation of vegetation by big herbivores, from the Pleistocene to now. The project aims to provide a coherent understanding of the effects of extinct and extant large herbivores on ecosystems over space and time. The structure and distribution of vegetation types is determined not only by climate and soils, but also by the impacts of herbivores and fire as consumers of plant biomass. Recent research has shown how fire shapes the large-scale distribution of vegetation types, but we do not have an equivalent understanding of the effects of large ground-dwelling herbivores. The project plans to test the effects of such animals on vegetation structure in the Pleistocene, when mega-herbivores were common, and today, and thus to compare the impacts of fire and herbivores on the distribution of vegetation types.Read moreRead less
How has bushfire activity varied around the Southern Hemisphere over the last 10,000 years? We will determine the relative contribution of climate and human ignitions in driving bushfire activity around the Southern Hemisphere over the last 10,000 years. Such knowledge is crucial for ecologically sustainable fire management, resolving debates about past Aboriginal environmental impacts and understanding the risk posed by climate change.
