Nutrition in the Gouldian finch - developing an optimal 'life-history diet'. Native Australian birds such as the budgerigar, cockatiel, cockatoo, zebra finch and Gouldian finch dominate the pet trade with tens of millions kept across the world. Currently these birds are fed inadequate diets based on a few generic seeds (of European origin). Our study will investigate the nutritional needs of the Gouldian finch and the nutritional content of native Australian seeds, ultimately designing an optima ....Nutrition in the Gouldian finch - developing an optimal 'life-history diet'. Native Australian birds such as the budgerigar, cockatiel, cockatoo, zebra finch and Gouldian finch dominate the pet trade with tens of millions kept across the world. Currently these birds are fed inadequate diets based on a few generic seeds (of European origin). Our study will investigate the nutritional needs of the Gouldian finch and the nutritional content of native Australian seeds, ultimately designing an optimal diet that will dramatically improve the health of these captive birds. We will develop a new product based on Australian plants, which are adapted to growing in even in the poorest soils and climates in Australia and which will form the basis of a new commercial crop for domestic and international markets.

Forest ecosystem water use: Does species diversity matter? Forest water use and susceptibility to drought are major concerns for forest plantation establishment in Australia. This research will provide fundamental information about how plantation water use and drought tolerance are modified by species diversity. This work has the potential to transform tree plantation establishment practices toward inclusion of greater species diversity or toward species with particular complementary traits. It ....Forest ecosystem water use: Does species diversity matter? Forest water use and susceptibility to drought are major concerns for forest plantation establishment in Australia. This research will provide fundamental information about how plantation water use and drought tolerance are modified by species diversity. This work has the potential to transform tree plantation establishment practices toward inclusion of greater species diversity or toward species with particular complementary traits. It has significant potential to enhance benefits from reforestation projects, including better drought survival, reduced water use, soil bioremediation and enhanced biodiversity. Read moreRead less
An Integrated Assessment of the Impacts of Climate Change on Vegetation in the Victorian Alps. This project will integrate novel approaches from experimental ecology, genetics and ecological monitoring to evaluate the potential effects of climate change on biodiversity in the Victorian Alps. Warming of alpine landscapes is increasingly likely, yet the potential impacts are poorly understood. We will examine the responses of key plant species to experimental warming, asses their inherent genetic ....An Integrated Assessment of the Impacts of Climate Change on Vegetation in the Victorian Alps. This project will integrate novel approaches from experimental ecology, genetics and ecological monitoring to evaluate the potential effects of climate change on biodiversity in the Victorian Alps. Warming of alpine landscapes is increasingly likely, yet the potential impacts are poorly understood. We will examine the responses of key plant species to experimental warming, asses their inherent genetic capacity to adapt to changing environmental conditions, and asses the consequences of individual species responses for broader habitat change using simulation modelling. The project will result in a sound framework for monitoring management strategies that anticipate climate change in the Australian Alps.Read moreRead less
Phylogeography and host specificity of stemborer parasitoids: essential components for the pre-emptive biocontrol of sugarcane pests in Australia. Stemboring insects cause huge economic losses to the sugar industry world-wide but fortunately these pests are largely absent from Australia, in part because quarantine measures have prevented their introduction. However, given their proximity, incursion of foreign stemborers from Asia pose a serious threat to Australian sugarcane. To prepare effectiv ....Phylogeography and host specificity of stemborer parasitoids: essential components for the pre-emptive biocontrol of sugarcane pests in Australia. Stemboring insects cause huge economic losses to the sugar industry world-wide but fortunately these pests are largely absent from Australia, in part because quarantine measures have prevented their introduction. However, given their proximity, incursion of foreign stemborers from Asia pose a serious threat to Australian sugarcane. To prepare effective pest management plans that can be adopted promptly in a worst-case scenario, this study will 1) develop molecular diagnostic tools to select wasp biocontrol agents that are suitable for the control of specific foreign stemborer pests, and 2) evaluate whether any Australian native wasps have the ability to kill foreign stemborers.

Fruit fly pests in northwestern Australia: invasion, hybridisation or evolution? In northwestern Australia, recent events suggest that a new and serious fruit fly pest is now present, wher previously none existed. Due to difficulties in accurate identification, we do not know whether these new pest fruit flies are endemic fruit flies that have changed their behaviour, invasions of Queensland fruit fly, or hybrids between them. This project will use DNA microsatellites to distinguish between th ....Fruit fly pests in northwestern Australia: invasion, hybridisation or evolution? In northwestern Australia, recent events suggest that a new and serious fruit fly pest is now present, wher previously none existed. Due to difficulties in accurate identification, we do not know whether these new pest fruit flies are endemic fruit flies that have changed their behaviour, invasions of Queensland fruit fly, or hybrids between them. This project will use DNA microsatellites to distinguish between these possibilities. It will also establish whether the different species involved are actually different species, or should be regarded merely as different races. Such distinctions are important both scientifically and for export quarantine purposes.Read moreRead less
Green roofs - improving urban environments in a changing climate. Green roofs are an emerging climate change adaptation technology that is widespread in Europe and North America, but rare and untested in Australia. Our research will significantly progress the Australian green roof industry by overcoming barriers to their implementation. This will lead to multiple environmental, economic and health benefits at a variety of scales. Benefits for individual buildings include greater energy efficienc ....Green roofs - improving urban environments in a changing climate. Green roofs are an emerging climate change adaptation technology that is widespread in Europe and North America, but rare and untested in Australia. Our research will significantly progress the Australian green roof industry by overcoming barriers to their implementation. This will lead to multiple environmental, economic and health benefits at a variety of scales. Benefits for individual buildings include greater energy efficiency, increased roof life and the attenuation of noise. Environmental benefits include biodiversity habitat, reduced volume and improved quality of stormwater flows and cooling of the urban environment. This will further reduce energy use and greenhouse emissions, while reducing human health risks during heat waves.Read moreRead less
Ecology, Physiology and Phylogeography: an integrated approach to the study of the invasive marine green macroalga Caulerpa taxifolia in Australia. The green marine macroalga Caulerpa taxifolia is one of the world's worst invasive species. In Australia 'exotic strains' of this alga are a listed pest species. Invasions in NSW and SA have caused environmental harm and managing them has cost $10 million since 2000. We propose to integrate ecology, physiology and genetic analyses to provide data to ....Ecology, Physiology and Phylogeography: an integrated approach to the study of the invasive marine green macroalga Caulerpa taxifolia in Australia. The green marine macroalga Caulerpa taxifolia is one of the world's worst invasive species. In Australia 'exotic strains' of this alga are a listed pest species. Invasions in NSW and SA have caused environmental harm and managing them has cost $10 million since 2000. We propose to integrate ecology, physiology and genetic analyses to provide data to better respond to this pest, potentially savings millions of dollars per year. We will produce the first empirical evidence of the effects of climate change and ocean acidification on this marine pest, in the context of increasing coastal human populations.Read moreRead less
Invasive plant species and climate change in Australia: predicting the threat and projecting the future. The interaction between climate change and invasive pest species poses a significant threat to Australia's biodiversity. The need for research on both the independent impacts of climate change and invasive species, as well as their interaction, has been clearly identified by both national and state governments, and is identified as a priority under the National Biodiversity and Climate Change ....Invasive plant species and climate change in Australia: predicting the threat and projecting the future. The interaction between climate change and invasive pest species poses a significant threat to Australia's biodiversity. The need for research on both the independent impacts of climate change and invasive species, as well as their interaction, has been clearly identified by both national and state governments, and is identified as a priority under the National Biodiversity and Climate Change Action Plan (2004-2007). The proposed research will assess exotic plant species' responses to climate change, identify potential hotspots of invasion, and provide a risk assessment framework to enable prioritization of exotic plant management under future climate.Read moreRead less
