This project will increase understanding of physiological and molecular mechanisms that enable widespread beneficial symbiotic soil fungi to influence plant productivity and biodiversity of natural and managed plant ecosystems. It will also aid biotechnological and agronomic goals of maximizing use of scarce soil nutrients, especially phosphate. Results will be important for agro-industry and Government groups focusing on 'healthy soil'. The project adds considerably to investment in research, infrastructure and international collaboration in this priority area. It will enhance Australia's reputation for research in soil biology and provide high standards in research education and training in an internationally recognised environment.Read moreRead less
Nutritional ecology of predatory arthropods: molecular analysis of gut contents to elucidate prey choice and diet breadth. The evolution of genetic resistance in insect pest populations against synthetic and biological pesticides requires new integrated pest management strategies with increasingly large biological control components. This is the only sustainable approach to pest management in agricultural production and natural ecosystems. Biological control of insect pests can potentially be ac ....Nutritional ecology of predatory arthropods: molecular analysis of gut contents to elucidate prey choice and diet breadth. The evolution of genetic resistance in insect pest populations against synthetic and biological pesticides requires new integrated pest management strategies with increasingly large biological control components. This is the only sustainable approach to pest management in agricultural production and natural ecosystems. Biological control of insect pests can potentially be achieved with indigenous generalist predators, thereby reducing the risks associated with importing exotic natural enemies. This project provides new opportunities for enhancing biological control by examining the diets of generalist predators using new diagnostic technologies. This is crucial for the effective and reliable use of predators in biological control.Read moreRead less
Integrating climate adaptation into rainforest restoration plantings. This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics.

This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics. For a suite of six species of tropical tree frequently employed in rainforest restoration plantings in northeast Queensland, this project aims to test the hypothesis that collecting seed from populations in similar ecoclimatic settings to the planting site will result in superior seedling growth and survival. The expected outcome is to provide practical advice to restoration practitioners about the importance of matching the provenance of seed source to planting sites, and opportunities for selecting provenances pre-adapted to predicted future climatic conditions at planting sites.Read moreRead less
Assessing the impact of a native parasitic plant, Cassytha pubescens, on the weeds gorse (Ulex europaeus) and English broom (Cytisus scoparius). Each year invasive plants cost Australia billions of dollars through costs associated with their control and through lost agricultural production and degradation of native ecosystems. Two particularly damaging plants are gorse and broom. The problems gorse causes are so serious that it has been recognized as a Weed of National Significance (Federal Depa ....Assessing the impact of a native parasitic plant, Cassytha pubescens, on the weeds gorse (Ulex europaeus) and English broom (Cytisus scoparius). Each year invasive plants cost Australia billions of dollars through costs associated with their control and through lost agricultural production and degradation of native ecosystems. Two particularly damaging plants are gorse and broom. The problems gorse causes are so serious that it has been recognized as a Weed of National Significance (Federal Department of Environment and Heritage). Biological control efforts have seldom use native agents, and even less often, parasitic plants. This project will help to develop strategies for the control of two noxious species using a native parsitic plant.Read moreRead less
Population genetics and dynamics of orchids and their pollinators in fragmented landscapes of South Australia. Many species of orchids in fragmented landscapes need active management to secure their persistence. The effects of fragmentation can be direct (e.g. reduction in population sizes, environmental quality, increased inbreeding, reduced dispersal ability), or indirect through negative effects on pollinators. Little information exists on the complex interactions between effects of fragmenta ....Population genetics and dynamics of orchids and their pollinators in fragmented landscapes of South Australia. Many species of orchids in fragmented landscapes need active management to secure their persistence. The effects of fragmentation can be direct (e.g. reduction in population sizes, environmental quality, increased inbreeding, reduced dispersal ability), or indirect through negative effects on pollinators. Little information exists on the complex interactions between effects of fragmentation on plants and their pollinators. This project aims to understand how fragmentation affects the genetic diversity and demography of selected populations of orchids and their pollinators in the Mt.Lofty/Flerieu Peninsula area. This information will help to develop and implement more effective conservation plans.Read moreRead less

Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ecoinformatics and evolutionary theory. Across this span, working groups will target nine identified opportunities for breakthrough research. Each research target needs input from two or more disciplines. Together, the nine targets link across disciplines, as a network that spans from genomic to planetary scales.Read moreRead less
