Summary
Chronic respiratory disease, tuberculosis and the effects of air pollution are important health problems globally. Evaluating current approaches to dealing with these problems and developing new approaches requires good data. Over the next five years I will lead a number of studies addressing these issues, in Australia and internationally, in order to provided the strongest possible evidence to underpin policy.
Impacts of groundwater extraction on ecophysiology of Australian trees. The aim of this project is to determine the response of trees to the extraction of shallow groundwater. Groundwater-dependent ecosystems rely on a supply of groundwater to maintain ecosystem health, structure and function, and excessive depletion of groundwater resources has a negative impact on these ecosystems. The project intends to combine a field-scale experimental depletion of groundwater resources simultaneously with ....Impacts of groundwater extraction on ecophysiology of Australian trees. The aim of this project is to determine the response of trees to the extraction of shallow groundwater. Groundwater-dependent ecosystems rely on a supply of groundwater to maintain ecosystem health, structure and function, and excessive depletion of groundwater resources has a negative impact on these ecosystems. The project intends to combine a field-scale experimental depletion of groundwater resources simultaneously with alterations in rainfall input and measurements of tree responses. The results of the project are intended to inform industry regulators and the water supply industry on how to improve management of both groundwater and vegetation resources.Read moreRead less
The effect of aerial spraying of two pesticides on semi-arid grasslands. The project will investigate how two pesticides, fipronil and metarrhizium, used to control locusts, affect semi-arid ecosystems by examining impacts on invertebrates, their predators, lizards and soil processes. The effects will be followed through time in a large scale experiment to determine recovery and compare each pesticide.
Watching migrating whales: ensuring the sustainability of a growing whale-watch industry. Whale-watching is a huge growth industry, contributing $270 million to Australia in 2003. Yet most whalewatching targets species listed under the EPBC Act 1999 as species slowly recovering from massive overexploitation. Current protection measures are historical (ie best-guess) rather than scientific in origin. We will assess the scientific basis for these protection measures by experimentally manipulating ....Watching migrating whales: ensuring the sustainability of a growing whale-watch industry. Whale-watching is a huge growth industry, contributing $270 million to Australia in 2003. Yet most whalewatching targets species listed under the EPBC Act 1999 as species slowly recovering from massive overexploitation. Current protection measures are historical (ie best-guess) rather than scientific in origin. We will assess the scientific basis for these protection measures by experimentally manipulating tour boat behaviour, and by determining the economic feasibility of the industry. By doing so we will increase the long-term sustainability of the industry, a valuable tourist industry for regional Australia.Read moreRead less
Mega spatial-scale, multi time-scale, ensemble assessment of climate change driven coastal change in South Eastern Australia. Climate change driven variations in mean sea level, storm surges, and waves will change the world's coastline. This project will, for the first time, develop innovative modelling methods to quantify the integrated impact of these climate drivers on coastal erosion along Australia's most developed and populated coastline: Sydney to Brisbane.
Integrating past ice sheet dynamics with palaeoclimate in the Weddell Sea sector to evaluate current and future change in Antarctica. This project will extend historical records of change and understand the complex linkages between Antarctic climate and ice sheet dynamics, thereby assisting in: (i) identifying the mechanisms of past and future ice sheet stability, and (ii) communicating the research outputs to the general public, helping scientific understanding.
Hydrological changes in Australia and the South Pacific. This project plans to use stalagmites from the South–West Pacific to generate continuous rainfall records for the last 2000 years. Stalagmites contain uncorrupted data that are not available in other archives, and provide unparalleled accurate chronologies. The spatial and temporal variations of the data may highlight the interplay of climate drivers, such as El Niño Southern Oscillation, and how they change the distribution of rainfall in ....Hydrological changes in Australia and the South Pacific.

The spatial and temporal variations of the data may highlight the interplay of climate drivers, such as El Niño Southern Oscillation, and how they change the distribution of rainfall in the Pacific. This knowledge would increase our scientific understanding and enable better predictions of the recurrence of droughts and wet events in Australia.Read moreRead less
Remotely sensed forest water use in space and time. Remotely sensed forest water use in space and time. This project aims to develop and apply new methods to scale forest water use from plot to catchment-level, using relationships between plot-level annual evapotranspiration and biophysical and biochemical properties of stands detectable by unmanned aircraft systems and other remote sensing platforms. Australia's water security depends on understanding how changes in forests from disturbance and ....Remotely sensed forest water use in space and time. Remotely sensed forest water use in space and time. This project aims to develop and apply new methods to scale forest water use from plot to catchment-level, using relationships between plot-level annual evapotranspiration and biophysical and biochemical properties of stands detectable by unmanned aircraft systems and other remote sensing platforms. Australia's water security depends on understanding how changes in forests from disturbance and climate change influence catchment water yields. This project will estimate water yields over time and space in ungauged catchments with disturbed eucalypt forests. This research is expected to enable more effective risk mitigation and planning for augmentations; improved fire management strategies; and better water management of the Murray Darling Basin.Read moreRead less
New methods for mapping variation in forest water use in time and space. Disturbance of eucalypt forests can have dramatic impacts on catchment water yields. In partnership with Melbourne Water Corporation, this project will develop and test new methods for accurate mapping of variation in water use across forested water supply catchments and for accurately determining the effects of this on water supplies.
Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidenc ....Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidence of these keystones’ cellular level biogeochemical and metabolic capacity. Ultimately, this knowledge is expected to predict the resilience of ocean ecosystems and their response to change. The capacity to predict their dynamics will help provide investment clarity and increase healthy outcomes from activities involving human-ocean interactions such as recreation, food production and tourism.Read moreRead less
