Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will b ....Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will be combined with isotopic analysis to reveal how environmental and biological factors drive animal movements and impact habitat connectivity. In a world of vanishing top predators, it is imperative to understand system dynamics before we can evaluate the impact of species removal on ecosystem function.Read moreRead less
Biomagnification of the biotoxin BMAA in the environment. Using unique models and technics, the project aims to demonstrate that long-term exposure to the blue green algae toxin β-N-methylamino-l-alanine (BMAA) leads to uptake, accumulation and toxicity within the central nervous system. The risks for heath, mechanisms of contamination and toxicity of BMAA are very poorly understood. Algal blooms cost the Australian community more than $250 million each year and represent a major health issue fo ....Biomagnification of the biotoxin BMAA in the environment. Using unique models and technics, the project aims to demonstrate that long-term exposure to the blue green algae toxin β-N-methylamino-l-alanine (BMAA) leads to uptake, accumulation and toxicity within the central nervous system. The risks for heath, mechanisms of contamination and toxicity of BMAA are very poorly understood. Algal blooms cost the Australian community more than $250 million each year and represent a major health issue for human and fauna. This project aims to be the first to fully characterise BMAA mechanisms of contamination and neurotoxicity and to highlight the major environmental risk of exposure of human to BMAA. It also aims to develop new and unique detection and quantification tools for BMAA.Read moreRead less
Australia's freshwater ecosystems: how microbial diversity and functionality influence harmful cyanobacterial blooms. Toxic cyanobacterial blooms are a constant threat to safe drinking water supplies. A bloom is a poorly understood interaction between many species and the environment. This project will investigate the entire microbial population and their physiologies present in a bloom event in order to identify potential targets for their management.
Optimising seasonal decisions for environmental water use. This project will develop a tool to optimise the use of environmental water, drawing on seasonal forecasts of streamflow and water price, and predicted ecological responses to changing flows. This tool will strengthen the effectiveness of the government organisations responsible for managing Australia's environmental water reserves.
Bad tastes, odours and toxins in our drinking water reservoirs: are benthic cyanobacteria the culprits? Cyanobacteria (blue-green algae) produce toxins and bad tastes that contaminate drinking water sources, cause public concern about water quality. This project will address a critical knowledge gap by investigating species that grow on the sediments of reservoirs, thus providing more comprehensive management solutions to the water industry.
A global standard for the status of Wetlands of International Importance. The project will develop and test a new global standard for the assessment and reporting on ecological condition of internationally important wetlands, listed under the Ramsar Convention. It has four aims: establishment of a strategic adaptive management and governance framework, a meta-analysis of the 2,303 internationally listed wetlands, development of a protocol for assessment and prediction and delivering a digital re ....A global standard for the status of Wetlands of International Importance. The project will develop and test a new global standard for the assessment and reporting on ecological condition of internationally important wetlands, listed under the Ramsar Convention. It has four aims: establishment of a strategic adaptive management and governance framework, a meta-analysis of the 2,303 internationally listed wetlands, development of a protocol for assessment and prediction and delivering a digital reporting platform for effective management. The project is significant because it tackles the decline of freshwater ecosystems, by targeting the most prominent wetlands. It also assists state and national governments to meet their obligations under the Ramsar Convention and most importantly guides more effective management.Read moreRead less
