New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ec ....New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ecogenomics offers a way to rapidly assess the composition of an ecological community. These techniques offer great promise, but they must be cross-validated against existing methods to derive the best ’toolbox’. Working with Melbourne Water and CSIRO the investigators aim to do this using demonstration estuaries in Victoria.Read moreRead less

Animal cultures and anthropogenic change. This project aims to investigate the impacts of anthropogenic change on the elaborate song cultures of declining Australian songbirds. Culture is fundamental to the biology of social animals, and has profound implications for biodiversity conservation; however, the drivers of animal cultural change are unclear. This project will analyse how lyrebird song cultures respond to anthropogenic environmental change, including Australia’s 2019-20 megafires. Furt ....Animal cultures and anthropogenic change. This project aims to investigate the impacts of anthropogenic change on the elaborate song cultures of declining Australian songbirds. Culture is fundamental to the biology of social animals, and has profound implications for biodiversity conservation; however, the drivers of animal cultural change are unclear. This project will analyse how lyrebird song cultures respond to anthropogenic environmental change, including Australia’s 2019-20 megafires. Furthermore, it will assess the mechanisms linking environmental and cultural change, and examine the utility of vocal cultures as bioindicators of ecological health. This project will advance fundamental research in animal culture and enhance the conservation of cultural diversity in the wild.Read moreRead less

Investing in ecological portfolios: retaining migratory strategies of fish. In finance, investors minimize risk and optimize long term returns by building stock portfolios with different attributes. This contingency strategy also occurs in ecological systems. We will use portfolio effects as a conceptual model to characterise the poorly known sub-population variations in migratory strategies of estuarine fish and their response to environmental conditions. In doing so, we will determine how envi ....Investing in ecological portfolios: retaining migratory strategies of fish. In finance, investors minimize risk and optimize long term returns by building stock portfolios with different attributes. This contingency strategy also occurs in ecological systems. We will use portfolio effects as a conceptual model to characterise the poorly known sub-population variations in migratory strategies of estuarine fish and their response to environmental conditions. In doing so, we will determine how environmental change drives variations in migratory strategies, impacts long-term growth and population trophic web dynamics. Outcomes will foster novel and dynamic management frameworks that enhance population stability despite the predicted volatility of environmental conditions.Read moreRead less

When and where are temperate reef communities vulnerable to ocean warming? This project will test in the laboratory and the field, when and where ocean warming will exceed the thermal limits of marine species and why certain species show greater sensitivity to warming temperatures than others. This project expects to generate robust estimates about how temperature sensitivity varies between populations across species’ ranges and identify the ecological implications for habitat loss in areas wher ....When and where are temperate reef communities vulnerable to ocean warming? This project will test in the laboratory and the field, when and where ocean warming will exceed the thermal limits of marine species and why certain species show greater sensitivity to warming temperatures than others. This project expects to generate robust estimates about how temperature sensitivity varies between populations across species’ ranges and identify the ecological implications for habitat loss in areas where thermal limits differ between key species. Expected outcomes include an enhanced capacity to detect when and where vulnerability hotspots will emerge that could jeopardise the immense social, ecological, and economic value of Australia’s temperate reefs, next to which 70% of Australians live, along 8,000 km of coastline.Read moreRead less
