Mathematical models and bioinformatic analyses of bacterial genome evolution. Bacteria are vital agents in earth's biosphere, breaking down and synthesising a wide variety of compounds. Some bacteria cause disease; others are exploited for a range of biotechnological applications. Bacteria have a remarkable ability to survive and thrive in changing conditions. For example, pathogenic bacteria confronted by antibiotics easily evolve resistance to them. With the reality of climate change, we expec ....Mathematical models and bioinformatic analyses of bacterial genome evolution. Bacteria are vital agents in earth's biosphere, breaking down and synthesising a wide variety of compounds. Some bacteria cause disease; others are exploited for a range of biotechnological applications. Bacteria have a remarkable ability to survive and thrive in changing conditions. For example, pathogenic bacteria confronted by antibiotics easily evolve resistance to them. With the reality of climate change, we expect more rapid shifts in the structure of bacterial communities, possibly leading to the emergence of new pathogens. The benefits of this project are to discover how the genetic structure of bacteria confer this flexibility, and to help keep Australia at the forefront of research in bioinformatics and mathematical biology.

We will dissect the interaction between an Australian butterfly and changing climate. This will make significant contributions to the national research priorities Responding to climate change and variability and Sustainable use of Australia's biodiversity. We will address the known deficits in standard approaches to predicting futures for biota. We will provide an Australian species in which the mechanisms of response to climate change are understood in detail. Our outputs will be directly applicable to other butterflies: 19 threatened taxa in Australia. The novelty of our approach will be of marked international interest, and will train Australian researchers in a new way of predicting biological impacts of climate change.Read moreRead less
Modelling the impact of simulated warming on marine microbial production of dimethylsulphide on a global scale. The ultimate goal of Earth systems science is to understand the planet's functioning well enough to explain past changes (eg ice ages) and to predict future states of the system (eg the magnitude of greenhouse warming). This is possible only if the climate system can be accurately modelled. This project aims to examine the effect of simulated climate change on the global production of ....Modelling the impact of simulated warming on marine microbial production of dimethylsulphide on a global scale. The ultimate goal of Earth systems science is to understand the planet's functioning well enough to explain past changes (eg ice ages) and to predict future states of the system (eg the magnitude of greenhouse warming). This is possible only if the climate system can be accurately modelled. This project aims to examine the effect of simulated climate change on the global production of dimethylsulphide (DMS) by marine microbial ecosystems. DMS has been hypothesised as an important biogenic feedback on global warming.
This work will provide the first ecosystem modelling estimates of the
global radiative forcing due to DMS and thus decrease the uncertainty in current climate projections.Read moreRead less
Effects of global climate change on marine phytoplankton: interactions between UV radiation and elevated atmospheric carbon dioxide levels. Global climate change is one of the most significant ecological challenges for the 21st Century. Phytoplankton contribute over 45% of the planet's annual net primary production and form the basis of most aquatic food chains. Conversely, some phytoplankton are toxic and cause problems in marine and fresh waters.

Global climate change is one of the most significant ecological challenges for the 21st Century. Phytoplankton contribute over 45% of the planet's annual net primary production and form the basis of most aquatic food chains. Conversely, some phytoplankton are toxic and cause problems in marine and fresh waters. Climate change can potentially disrupt aquatic foodchains by its impact on primary production by phytoplankton or stimulating growth of potentially toxic forms. Our project will investigate the combined impact of increasing carbon dioxide and ultraviolet light on phytoplankton and thereby help climate modellers assess the impact of climate change on aquatic ecosystems and particularly on the nation's and the world's fisheries.Read moreRead less
