Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interac ....Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interactions, whilst models do not represent the functional characteristics and adaptions of eucalypts. This project will develop a strong evidence- and process-based understanding to quantify the functional behaviour of drought-adapted Eucalyptus species and leverage this insight to make future model projections.Read moreRead less
Bubble, Bubble CO2 is the trouble: A Natural Ocean Acidification Experiment in a coral reef setting. Carbon dioxide seep sites expose shallow coral reefs in Papua New Guinea to volcanic carbon dioxide resulting in gradients of seawater ranging from pH 8.0 (normal) to a more acidic pH of 7.5. Some areas of these reefs experience carbon dioxide exposure equivalent to IPCC predictions for 2050 and 2100. This project will reconstruct seawater pH using radiocarbon as a novel tracer of carbon dioxide ....Bubble, Bubble CO2 is the trouble: A Natural Ocean Acidification Experiment in a coral reef setting. Carbon dioxide seep sites expose shallow coral reefs in Papua New Guinea to volcanic carbon dioxide resulting in gradients of seawater ranging from pH 8.0 (normal) to a more acidic pH of 7.5. Some areas of these reefs experience carbon dioxide exposure equivalent to IPCC predictions for 2050 and 2100. This project will reconstruct seawater pH using radiocarbon as a novel tracer of carbon dioxide input at a coral reef site that has been exposed to high carbon dioxide due to volcanic seeps (seep carbon dioxide has no carbon-14) for an unknown period of time (at least many decades, but possibly centuries). These results will help to understand the time it takes to change calcifying organisms into “winners” or “losers” as an analog for Ocean Acidification due to increased atmospheric carbon dioxide input.Read moreRead less
The role of drought-stress and insect attack on rainforest plant health. This project aims to examine the vulnerability of tropical plants to drought and insect attack in a large-scale field experiment. We will pioneer a new research approach that focuses on the causes and stages of decline in plant health prior to death, in order to identify the characteristics of plant species that make them more susceptible to drought and insect attack. Expected outcomes of this project include an improved ca ....The role of drought-stress and insect attack on rainforest plant health.

We will pioneer a new research approach that focuses on the causes and stages of decline in plant health prior to death, in order to identify the characteristics of plant species that make them more susceptible to drought and insect attack. Expected outcomes of this project include an improved capacity to predict the function and composition of future forests. This project will provide significant benefits to communities concerned with the direct and indirect effects of droughts in protected areas, forestry reserves and agriculture. Read moreRead less
Changing ocean temperatures and movements of marine predators: the performance of marine protected areas in a warming ocean. Large predatory fish are essential to a balanced ecosystem and require protection from overfishing. Understanding what conditions cause them to migrate outside their normal home ranges will enable marine park managers to better design protection zones, both now and under future climate scenarios.

Trait plasticity and the maintenance of functional diversity. This project aims to determine if trait plasticity mediates functional degradation of coral reefs. It will use natural environmental gradients to identify mechanisms that enable corals to persist in marginal habitats. The project will use three-dimensional imaging to measure how variability in traits influences functional redundancy. This will facilitate better predictions of the effects of environmental change on reef systems. Expect ....Trait plasticity and the maintenance of functional diversity. This project aims to determine if trait plasticity mediates functional degradation of coral reefs. It will use natural environmental gradients to identify mechanisms that enable corals to persist in marginal habitats. The project will use three-dimensional imaging to measure how variability in traits influences functional redundancy. This will facilitate better predictions of the effects of environmental change on reef systems. Expected outcomes include improved understanding of the response of coral reef ecosystems to environmental change and a framework for predicting reefs at risk of degradation. Benefits will be to both global biodiversity conservation and the provision of ecosystem services in reef dependent communities.Read moreRead less
Predicting the consequences of drought-induced mortality for tree species in a changing climate. Tree mortality will be a dramatic manifestation of climate change as drought intensifies. A pre-existing record of mortality after recent drought in Eucalyptus woodland defines the moisture sensitivity of tree species and will be related to their functional traits, population dynamics and geography. This analysis will search for generalised characters that define the species that will be most suscept ....Predicting the consequences of drought-induced mortality for tree species in a changing climate. Tree mortality will be a dramatic manifestation of climate change as drought intensifies. A pre-existing record of mortality after recent drought in Eucalyptus woodland defines the moisture sensitivity of tree species and will be related to their functional traits, population dynamics and geography. This analysis will search for generalised characters that define the species that will be most susceptible to drought and will identify how future exaggerated drought will reorganise forest communities. The findings will contribute to understanding the vulnerability and resilience of our natural ecosystems with a changing climate.Read moreRead less

A shared mass spectrometer with compound-specific capabilities to support innovative research in biology, the environment and geology: Stable isotope studies have huge and increasing relevance to environmental studies, many of which form the backbone of understanding Australia's terrestrial and marine systems. Compound-specific isotope analysis yields much more information than is available through bulk methods. The problem has been that the separations were labour-intensive and employed complex wet chemistry. New methods reduce the work-load enough to make compound-specific studies possible. In the case of carbon isotopes, new liquid chromatographic technology removes the need for derivatisations which dilute the natural signal and can render it unusable.Read moreRead less
