Meta-modelling of ecological, evolutionary and climatic systems dynamics. This project aims to improve forecasts of the response of biodiversity to future climate change and so improve on-ground conservation management. Using dynamic systems modelling, tested against field data from a wide variety of case studies, the project models will integrate a variety of biological and geophysical inputs to produce more realistic forecasts of change.
Generalised methods for testing extinction dynamics across geological, near and modern time scales. The record of extinctions over deep time is patchy and incomplete, yet we must use it to determine how major changes in past environments have shaped life on Earth today. The project will develop cutting-edge mathematical tools to determine the patterns of extinctions and speciation over geological time to help predict our uncertain environmental future.
East Antarctica: subglacial heat flux constraints for ice sheet modelling. This project aims to quantify the heat flux from the East Antarctic continent into the base of the ice sheet via the derivation of a large geochemical database, together with elevation-based modelling and new heat flux measurements in regions formerly contiguous with East Antarctica. This subglacial heat flux is poorly constrained in current ice sheet models, but directly affects ice sheet behaviour. The output of this pr ....East Antarctica: subglacial heat flux constraints for ice sheet modelling. This project aims to quantify the heat flux from the East Antarctic continent into the base of the ice sheet via the derivation of a large geochemical database, together with elevation-based modelling and new heat flux measurements in regions formerly contiguous with East Antarctica. This subglacial heat flux is poorly constrained in current ice sheet models, but directly affects ice sheet behaviour. The output of this project will be a greatly improved heat flux map for East Antarctica that can be used in ice sheet modelling studies. This should drive significant improvement in models for the evolution of the East Antarctic Ice Sheet, resulting in more accurate projections of ice discharge and associated sea level change.Read moreRead less
Fire, air, water and earth: Using fossils to discover the evolution of Australia’s open vegetation. How Australia came to be dominated by open, tough-leaved vegetation is an old but still highly controversial question, especially with recent developments in molecular biology that challenge paradigms established from the fossil record. The project will test this new molecular paradigm with innovative use of characteristics of fossil leaves to identify the timing and drivers of the evolution of Au ....Fire, air, water and earth: Using fossils to discover the evolution of Australia’s open vegetation. How Australia came to be dominated by open, tough-leaved vegetation is an old but still highly controversial question, especially with recent developments in molecular biology that challenge paradigms established from the fossil record. The project will test this new molecular paradigm with innovative use of characteristics of fossil leaves to identify the timing and drivers of the evolution of Australia’s open vegetation. The integration of new and rigorous evidence derived from living and fossil plants will provide the clearest evidence yet for the origins of Australian environments. This has ramifications for understanding plant responses to past and future climate changes.Read moreRead less
Towards an Active and Passive L- and P-band soil moisture satellite mission. This project tests alternate configurations for remote sensing of soil moisture using a new state-of-the-art Active/Passive (ie radar/radiometer) P-/L-band (ie microwave) satellite concept through a series of airborne field experiments. Timely soil moisture information is critical to improved water management for food production in the face of climate variability. The challenge is to do this accurately over large areas ....Towards an Active and Passive L- and P-band soil moisture satellite mission. This project tests alternate configurations for remote sensing of soil moisture using a new state-of-the-art Active/Passive (ie radar/radiometer) P-/L-band (ie microwave) satellite concept through a series of airborne field experiments. Timely soil moisture information is critical to improved water management for food production in the face of climate variability. The challenge is to do this accurately over large areas with an appropriate spatio-temporal detail, and for a soil depth that closely approximates the layer which impacts crop/pasture growth and influences management decisions. The longer P-band allows deeper penetration into the soil while the active/passive combination uses the respective resolution and accuracy characteristics.Read moreRead less
Capturing Proteus: 65 million years of ecosystem change revealed through evolution of Proteaceae in Australasia. By assessing past changes in the iconic Australian plant family Proteaceae, this research will show how the Australasian vegetation has responded to 65 million years of profound landscape and climate changes. This knowledge from the past will give important insights into how ecosystems can be expected to change under future climate scenarios.
