Molecular biosignatures for isolating pollution problems in aquatic ecosystems using macroinvertebrate bioindicators. 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 ....Molecular biosignatures for isolating pollution problems in aquatic ecosystems using macroinvertebrate bioindicators. 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
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
Preserving freshwater biodiversity: predictions to manage the effects of suspended sediment and salinity. Natural resource managers wish to minimise deleterious effects of suspended sediment and salinity on biodiversity but do not have adequate knowledge to do so. Increases in salinity and sediment are recognised as the major threats to freshwater biodiversity in Australian rivers. This research will lead to greatly enhanced information on the relative impacts of rising salinity and sediment on ....Preserving freshwater biodiversity: predictions to manage the effects of suspended sediment and salinity. Natural resource managers wish to minimise deleterious effects of suspended sediment and salinity on biodiversity but do not have adequate knowledge to do so. Increases in salinity and sediment are recognised as the major threats to freshwater biodiversity in Australian rivers. This research will lead to greatly enhanced information on the relative impacts of rising salinity and sediment on freshwater biodiversity and aid predictive modelling and scenario testing; enabling managers to make informed choices between various management actions. The project addresses several national research priority goals and it will result in significant national and community benefits by protecting freshwater biodiversity from salinity and sediment.Read moreRead less
