This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics. For a suite of six species of tropical tree frequently employed in rainforest restoration plantings in northeast Queensland, this project aims to test the hypothesis that collecting seed from populations in similar ecoclimatic settings to the planting site will result in superior seedling growth and survival. The expected outcome is to provide practical advice to restoration practitioners about the importance of matching the provenance of seed source to planting sites, and opportunities for selecting provenances pre-adapted to predicted future climatic conditions at planting sites.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. This project aims to examine the vulnerability of tropical plants to drought and insect attack in a large-scale field experiment.

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
Response and vulnerability of tropical rainforest plants to experimental drought. This project will assess the vulnerability of rainforest plants to a large-scale experimental drought in the Daintree rainforest of north Queensland, using a canopy crane to access all vertical forest layers. This will provide a unique opportunity to understand how rainforests could be affected by future climate change.
Global change: Rainforest responses to experimental drought. How will rainforests respond if droughts increase in the future? In a globally unique experiment, this project will examine how Australian tropical rainforests are affected by a large-scale experimental drought, using a canopy crane to assess plant responses at all vertical forest levels. It will contrast demographic and physiological responses of an array of plant species and functional groups between experimental and control plots wh ....Global change: Rainforest responses to experimental drought. How will rainforests respond if droughts increase in the future? In a globally unique experiment, this project will examine how Australian tropical rainforests are affected by a large-scale experimental drought, using a canopy crane to assess plant responses at all vertical forest levels. It will contrast demographic and physiological responses of an array of plant species and functional groups between experimental and control plots where tree growth, composition, soil water and atmospheric exchange have been monitored since 1999. Drought responses of key species and functional groups will be compared with their distributions across regional rainfall gradients to yield crucial insights into the potential impacts of future climate change on rainforests.Read moreRead less
Advancing knowledge of microbial symbioses underpinning coral health and reef resilience and predicting their responses to climate change. Coral reefs are complex, diverse ecosystems in which microbial communities form associations with host corals. However, the roles these associations play in coral stress responses are unknown. This project unlocks the black-box of coral microbial complexity and determines how the reef’s smallest members have the greatest influence on reef health.
Resilience of Coral Reef Ecosystems to Climate Change. Science-based management of coral reefs provides enormous environmental, social and economic benefit to Australia and other tropical maritime nations. The proposed research will provide scientific knowledge and research training that underpins the management and long-term sustainability of Australian reef resources.

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
Hydraulic control on water use, growth and survival in tropical rainforest. This project aims to measure drought-related limits to water transport in the woody xylem tissue of trees in Australian tropical rainforests, to understand how this influences tree water use, photosynthesis, health and mortality risk. Tropical rainforests are sensitive to climate variability, especially drought, but this sensitivity is poorly understood, despite large effects regionally and globally. This project will co ....Hydraulic control on water use, growth and survival in tropical rainforest. This project aims to measure drought-related limits to water transport in the woody xylem tissue of trees in Australian tropical rainforests, to understand how this influences tree water use, photosynthesis, health and mortality risk. Tropical rainforests are sensitive to climate variability, especially drought, but this sensitivity is poorly understood, despite large effects regionally and globally. This project will compare forests that contrast strongly in seasonal drought stress, and use the information to develop a model designed for species-diverse forest, with subsequent potential global application. The understanding gained will enable widely applicable advances designed to feed through rapidly to regional- and global-scale models that inform land use, economic and social policy-making.Read moreRead less
