Environmental DNA: Integration of new methods to enhance marine management. This project aims to develop new environmental DNA (eDNA)-based methods of managing humanity’s impact on valuable marine resources. eDNA preserved in seawater provides a lens to study and monitor marine biota and ecosystems. This project will work with fisheries managers and the environmental consulting sector, and focus on sites in the Kimberley, Cocos-Keeling Islands, Fremantle and Deep-sea oil/gas sites to demonstrate the value of eDNA methods in best-practice monitoring. A multi-proxy toolkit (including eDNA) that can audit and baseline marine biota could make balancing conservation and sustainable exploitation achievable. Anticipated outcomes are improved management and monitoring of fisheries, ports and offshore oil/gas sites.Read moreRead less

The development and application of technologies and knowledge for enhancing sustainable management of semi-arid environments are of high priority and significant economic, social and environmental benefit. The value of iron ore exports from the Pilbara is expected to grow by nearly 30% in the next year, while the projected production of iron ore over the next 4 years is expected to be valued in excess of 60 billion dollars. However, continued and rapid expansion in the development of these resources is contingent on environmental oversight and adoption of an adaptive management approach. This research will thus make a major contribution to understanding the Pilbara ecosystems that provide tremendous economic wealth for all Australians.Read moreRead less
Impact of increased sediment and nutrient discharges on the long-term sustainability of the Great Barrier Reef. The Great Barrier Reef, one of Australia's greatest natural assets, is under increasing threat from extreme climatic events caused by global warming and from land-based pollution. This research will identify the main sources of sediment and nutrient pollution caused by river runoff and by how much this has increased above 'natural levels'. We will discover how the very sensitive offsho ....Impact of increased sediment and nutrient discharges on the long-term sustainability of the Great Barrier Reef. The Great Barrier Reef, one of Australia's greatest natural assets, is under increasing threat from extreme climatic events caused by global warming and from land-based pollution. This research will identify the main sources of sediment and nutrient pollution caused by river runoff and by how much this has increased above 'natural levels'. We will discover how the very sensitive offshore coral reefs have responded to increased pollution and whether this is the cause of the very devastating crown-of-thorn-starfish infestations. Understanding the long-term effects of land-based pollution on the ecology of coral reefs in the GBR will thus provide a scientific basis to help ensure that it has a sustainable future.Read moreRead less

Mining, irrigation, and groundwater: Towards a reliable protocol for assessing the impacts of extraction on groundwater fauna and ecology. Groundwater fluctuations associated with mining and increased irrigation demands, potentially threaten many of Australia's unique groundwater invertebrates (stygofauna) with extinction. Stygofauna represent a hidden store of biodiversity and are thought to have a critical, but poorly understood, role in enhancing groundwater quality.

Groundwater fluctuations associated with mining and increased irrigation demands, potentially threaten many of Australia's unique groundwater invertebrates (stygofauna) with extinction. Stygofauna represent a hidden store of biodiversity and are thought to have a critical, but poorly understood, role in enhancing groundwater quality. Environmentally sustainable development of groundwater resources is hampered by a dearth of information on the ecological needs of stygofauna and how they respond to human-induced change. Using field and laboratory experiments, we aim to determine how water table fluctuations threaten stygofauna. From our results we will develop sampling and management protocols to monitor and protect stygofauna communities.Read moreRead less
