Aquatic ecosystems are under increasing threat by human activities. This has been further exacerbated by drought and climate change. In the future, understanding the major factors impairing aquatic ecosystems will be a vital part of sustaining water resources. This project develops new molecular tools to better monitor and assess aquatic pollution. We will develop a new high-tech deoxyribonucleic acid (DNA) approach to identify insect indicator species and combine this with a field-based microcosm method that uses local aquatic insects to isolate pollution effects from other impacts. This proposal will facilitate fast identification of pollution problems and provide the water industry with an innovative means to assess pollution and monitor remedial actions.Read moreRead less
ARC Australia-New Zealand Research Network for Vegetation Function. 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, ....ARC Australia-New Zealand Research Network for Vegetation Function. 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
Testing the waters: impacts of contaminants on ecosystem structure and function in urban waterways. To ensure that people can swim, catch fish and enjoy the beauty of urban waterways we need to be able to predict the effects of more than one stressor at a time. This project will determine how nutrients and metals affect our waterways. Findings will help prioritise management actions that protect biodiversity and human uses of these systems.
Linking freshwater flows, salt wedge dynamics and fisheries productivity in estuaries. Freshwater is a critical resource in Australia, but there is a perception that freshwater running to the sea is wasted. Australia's estuaries are of great importance - economically, socially and environmentally. Estuaries provide habitat for unique and endangered animals and plants, support valuable fisheries, and have enormous recreational value, particularly in regional communities. Our lack of understanding ....Linking freshwater flows, salt wedge dynamics and fisheries productivity in estuaries. Freshwater is a critical resource in Australia, but there is a perception that freshwater running to the sea is wasted. Australia's estuaries are of great importance - economically, socially and environmentally. Estuaries provide habitat for unique and endangered animals and plants, support valuable fisheries, and have enormous recreational value, particularly in regional communities. Our lack of understanding about the effects of freshwater flows on estuarine productivity impedes decision making on the allocation of water to sustain healthy estuaries. The health of Australia's estuaries and sustainability of their resources, particularly fisheries, depend on understanding their freshwater requirements and securing environmental flows.Read moreRead less
Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity a ....Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity and function of coastal seascapes is to be conserved. This project aims to use a combination of novel modelling, surveys, and large experiments to understand how threatened seagrass, fish, and sediment habitats are altered in human modified seascapes, and to assess the success of habitat restoration following the removal of boating structures.Read moreRead less
Contemporary ecological threats from historical pollution events and their modification by environmental conditions. Many Australian ports have contaminated sediments that are a legacy of industrial pollution. The resuspension of these sediments through shipping or dredging activity represents an obvious, yet unsubstantiated, threat to the biodiversity and health of marine communities living well above the seafloor. This research proposal addresses a strategic knowledge gap with implications for ....Contemporary ecological threats from historical pollution events and their modification by environmental conditions. Many Australian ports have contaminated sediments that are a legacy of industrial pollution. The resuspension of these sediments through shipping or dredging activity represents an obvious, yet unsubstantiated, threat to the biodiversity and health of marine communities living well above the seafloor. This research proposal addresses a strategic knowledge gap with implications for appropriate management of port operations. Identifying the conditions under which contaminated sediments may cause an impact, and the environmental factors that modify these effects, will produce significant advances in scientific understanding and the results will be of strategic interest to all Australian Port Authorities.

Summary
From sink to source: does microbial priming of degraded seagrasses contribute to global warming? Australian seagrasses are among the planet's most effective natural systems for removing greenhouse gases; but, if degraded, they could leak stored carbon and accelerate global warming. This project will test the emerging paradigm that microbes control carbon leakage, thereby providing information to ensure that seagrass carbon remains locked away.

Assessing the ecological costs and benefits of artificial wetlands in urban landscapes. The nature and distribution of wetlands around cities is changing at an unprecedented rate, with artificial wetlands increasingly dominating urban landscapes. The consequences of these changes for animals, however, are largely unknown. Some artificial wetlands may be poor quality habitats that pose considerable risks to urban biodiversity, while others may play an important role in conservation. The project a ....Assessing the ecological costs and benefits of artificial wetlands in urban landscapes. The nature and distribution of wetlands around cities is changing at an unprecedented rate, with artificial wetlands increasingly dominating urban landscapes. The consequences of these changes for animals, however, are largely unknown. Some artificial wetlands may be poor quality habitats that pose considerable risks to urban biodiversity, while others may play an important role in conservation. The project aims to examine the ecological costs and benefits of artificial wetlands for native animals, and provide guidelines to help ensure wetland construction and management is cost effective and maximises biodiversity outcomes.Read moreRead less
