Enhancing natural enemy mortality of chrysomelids in young eucalypt plantations through habitat manipulation. Eucalyptus plantations are the future of Australian forestry. In eucalypt plantations leaf-feeding beetles reduce tree growth by an average of 53%, substantially reducing profits. Sustainable management of these pests is best done by maximising the impact of native beneficial agents, eg wasps and spiders. This research will quantify the beneficial insects in plantations and increase ....Enhancing natural enemy mortality of chrysomelids in young eucalypt plantations through habitat manipulation. Eucalyptus plantations are the future of Australian forestry. In eucalypt plantations leaf-feeding beetles reduce tree growth by an average of 53%, substantially reducing profits. Sustainable management of these pests is best done by maximising the impact of native beneficial agents, eg wasps and spiders. This research will quantify the beneficial insects in plantations and increase their efficacy by manipulating the plantation environment so it provides more of the resources (food & shelter) these beneficials require. This approach is significant as it has not been previously attempted in forestry. Our management recommendations will make the plantation sector more profitable and sustainable.Read moreRead less
Forestry effects on headwater ecosystem health: a multi-catchment experiment. Most catchments in southern Australia have been logged historically. Increasingly, native forest harvesting occurs in regrowth or drier areas. Although foresters have empirical data on ecological effects of harvesting in pristine or wetter catchments, little exists for drier regrowth areas, hampering effective management to minimize impacts on stream ecosystem health. This project will supply ecological data on stre ....Forestry effects on headwater ecosystem health: a multi-catchment experiment. Most catchments in southern Australia have been logged historically. Increasingly, native forest harvesting occurs in regrowth or drier areas. Although foresters have empirical data on ecological effects of harvesting in pristine or wetter catchments, little exists for drier regrowth areas, hampering effective management to minimize impacts on stream ecosystem health. This project will supply ecological data on stream ecosystems to supplement 4 years of hydrological data collected by Forests NSW from 5 experimental catchments. Results will provide a firmer scientific basis for ecologically sustainable harvesting in this forest type, with flow-on benefits to our national economy, biodiversity, and environment.Read moreRead less

The ongoing pursuit of new medicines and therapies, the development of sustainable forestry management practices and the assessment of the impact of global climate change on Australian forest soils are some of the research objectives being addressed by researchers at Griffith University. The Eskitis Institute for Cell and Molecular Therapies and the Centre for Forestry and Horticultural Research (CFHR) bring together researchers from a range of disciplines to further research in these key areas. The instruments funded here will provide researchers with access to spectroscopic facilities with state-of-the-art performance. This will ensure the continued international competitiveness and the sustained productivity of our research programmes.Read moreRead less
Feasting on protein? Strategies of organic nitrogen acquisition by plant roots. Crops require large amounts of nitrogen for growth. Application of nitrogen fertiliser enhances yield, but causes off-site nitrogen pollution, a main threat to ecosystem integrity. Most nitrogen in soil occurs as organic complexes that are broken down by soil organism into small compounds, which are taken up roots or lost from the soil. This project will generate fundamental knowledge of how an Australian species and ....Feasting on protein? Strategies of organic nitrogen acquisition by plant roots. Crops require large amounts of nitrogen for growth. Application of nitrogen fertiliser enhances yield, but causes off-site nitrogen pollution, a main threat to ecosystem integrity. Most nitrogen in soil occurs as organic complexes that are broken down by soil organism into small compounds, which are taken up roots or lost from the soil. This project will generate fundamental knowledge of how an Australian species and a crop species with unusual root specialisations access soil organic nitrogen, thus increasing the efficiency of nitrogen use and reducing nitrogen loss. The research employs cutting-edge techniques for sustainable resource use, improved efficiency of crops and farming systems, and preservation of Australia's biodiversity.Read moreRead less

Summary
The Insect-Plant Chemical Ecology Network (IPCEN). We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together.

We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together. This will lead to new research outcomes and solutions to problems in agriculture, horticulture, forestry and protection of Australia's native flora. Researchers are struggling to create these links, constrained by disciplinary boundaries and geographical isolation. Key industries and researchers already support this proposal.Read moreRead less
