Plant secondary metabolites (PSMs) are considered to protect against herbivory, although the mechanisms are not well understood. This project will determine how marsupial folivores avoid toxicity when browsing on Eucalyptus leaf. Blood levels of terpenes, phenols and their metabolites will be measured in the brushtail possum while it feeds on a diet of varying PSM content. We expect to be able to show relationships between the ingestion and blood levels of PSMs and feeding behaviour. This will give a greater understanding of the effect of plant toxins on browsing behaviour, enabling improved foraging models and more effective habitat management.Read moreRead less

Keystone effects of Australia's top predators: dingoes, devils and biodiversity. This project will study the interactions of Australia's two largest predators, the dingo and Tasmanian devil, with other species. The project will help develop an understanding of the value of these predators in maintaining ecosystem processes and diversity, and guide their management in the future.
Partitioning of primary production by crustacean grazers in the Antarctic sea ice zone. Crustaceans are an important component of the Antarctic marine ecosystem. Large numbers live in or close to the sea-ice cover, using it as a refuge from predation and a source of food. However, the impact of these animals on algae that grows in the sea-ice is unknown. This study will examine the diets and grazing rates of crustaceans in the Antarctic sea-ice ecosystem. These results will aid our understanding ....Partitioning of primary production by crustacean grazers in the Antarctic sea ice zone. Crustaceans are an important component of the Antarctic marine ecosystem. Large numbers live in or close to the sea-ice cover, using it as a refuge from predation and a source of food. However, the impact of these animals on algae that grows in the sea-ice is unknown. This study will examine the diets and grazing rates of crustaceans in the Antarctic sea-ice ecosystem. These results will aid our understanding of the fate of algal production in sea-ice and will enable the construction of realistic carbon budgets for this ecosystem.Read moreRead less

Novel governance for marine ecosystems in rapid transition. This project will develop the governance knowledge required to manage rapidly changing marine ecosystems. Australia has the third largest marine estate globally, and its ecosystems support critical economic and sociocultural values. However, human pressures are tipping marine ecosystems into alternate states, inspiring new interventions to sustain industries and communities. New interventions necessitate transitions in governance. Expec ....Novel governance for marine ecosystems in rapid transition. This project will develop the governance knowledge required to manage rapidly changing marine ecosystems. Australia has the third largest marine estate globally, and its ecosystems support critical economic and sociocultural values. However, human pressures are tipping marine ecosystems into alternate states, inspiring new interventions to sustain industries and communities. New interventions necessitate transitions in governance. Expected outcomes include a comparative understanding of novel marine interventions now underway globally, and practical guidance on how to diagnose and implement responsible marine governance. Significant benefits include enhanced governance and sustainability of Australian and international marine ecosystems.Read moreRead less
Understanding the impact of global environmental change on Australian forests and woodlands using rainforest boundaries and Callitris growth as bio-indicators. Human-caused climate change is a fact but the ecological responses are uncertain. These could include accelerated tree growth, expansion of rainforest, and thickening of woodlands, although cessation of Aboriginal firing may be equally important. We will provide a historical context to understand how and why Australian forests have change ....Understanding the impact of global environmental change on Australian forests and woodlands using rainforest boundaries and Callitris growth as bio-indicators. Human-caused climate change is a fact but the ecological responses are uncertain. These could include accelerated tree growth, expansion of rainforest, and thickening of woodlands, although cessation of Aboriginal firing may be equally important. We will provide a historical context to understand how and why Australian forests have changed. Our results will inform management and policy debates about (i) rainforest conservation (ii) the role of fire in forest management (iii) the likely impact of increased CO2 ('fertiliser effect') of forest productivity (iv) national carbon accounting and (v) the consequences of climate change on forest ecosystems, particularly the respective wetting and drying trends in the north and south of Australia.Read moreRead less

How to meet human needs for timber while limiting harm to biodiversity is an urgent scientific goal. The project will address this challenge by quantifying the impacts of forestry systems and wildfire on mammal species. Novel network modelling of interactions among plants, animals, and environmental variables will establish cost-effective management improvements to maximise biodiversity values. A systematic conservation planning approach will deliver spatially and temporally explicit solutions to balancing trade-offs between production and conservation taking into account dynamic impacts from climate change and fire. Outcomes will provide a foundation for policy changes to put theoretical solutions into practice.Read moreRead less

Assessment of plant health and productivity is vital to ensure future food security of the global population under a changing climate. Chlorophyll fluorescence (CF), a signal emitted by green plants, can reveal this information. Although CF has revolutionised photosynthetic research, current measurements are limited to individual plants. Remote sensing of canopy CF is required for efficient management of agricultural crops, forests, and natural ecosystems and is crucial for accurate estimation of plant carbon assimilation and production. This project will deliver remote sensing technology to bridge the gap between leaf and canopy productivity and pave the way for understanding both artificial and solar induced canopy CF measured from space.Read moreRead less
