Avoiding coral bleaching: investigation into the repair of damaged photosynthetic machinery in symbiotic algae (symbiodinium) within corals. Photosynthesis in symbiotic algae within corals is essential for a healthy alga-coral symbiotic relationship. This project will provide new insights into how symbiotic algae maintain higher photosynthetic performance in corals through elucidating the mechanism associated with the repair of photodamaged photosynthetic machinery.

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
Will stomatal responses to humidity and carbon dioxide constrain tropical forest productivity as atmospheric carbon dioxide rises? This project will investigate two physiological processes that will partly determine growth responses of tropical forest trees to rising atmospheric carbon dioxide. The project will produce equations summarising physiological responses that can be incorporated into process-based models of tropical forest productivity.
Temperature response and thermal acclimation of mesophyll conductance. Photosynthetic rate and efficiency depend on diffusion of carbon dioxide from the atmosphere into leaf mesophyll cells. Carbon dioxide diffusion is affected by temperature, but we lack knowledge of how this varies between plant species. Stable isotope methodology will be used to characterise the temperature response of this carbon dioxide diffusion step. Plants from contrasting climates will be grown in different temperature ....Temperature response and thermal acclimation of mesophyll conductance. Photosynthetic rate and efficiency depend on diffusion of carbon dioxide from the atmosphere into leaf mesophyll cells. Carbon dioxide diffusion is affected by temperature, but we lack knowledge of how this varies between plant species. Stable isotope methodology will be used to characterise the temperature response of this carbon dioxide diffusion step. Plants from contrasting climates will be grown in different temperature regimes to reveal the extent of variation in adaptation and acclimation to temperature. This will provide new insights towards modifying photosynthesis to increase crop yield and it will also improve forecasting of global atmospheric carbon dioxide fluxes derived from the analysis of atmospheric isotope data.Read moreRead less
Reading the isotopic archive: carbon and oxygen stable isotope ratios as recorders of plant physiological processes. This project will investigate how plant physiological processes are reflected in stable isotope ratios of carbon and oxygen in plant tissues. Results will contribute towards a mechanistic understanding of the processes that cause isotopic modifications, thereby enabling an improved interpretation of naturally occurring stable isotope signals.

Summary
Spectral climate chamber facilities for phenomic studies of plant light response adaptation. Climates are changing, altering planting regimes in agriculture, and disrupting local adaptation in foundation species. The genetic basis of climate adaptation will be dissected in new plant growth facilities, equipped with real-time imaging and environmental controls that can mimic dynamic seasonal growing conditions and weather stress events.

Understanding the mechanisms of thermal acclimation in the symbiotic algae (Symbiodinium) within cnidarian corals. Global warming is a major threat to coral reefs, contributing to devastating coral bleaching. This project will provide new insight into how coral reefs can respond to rising global temperature through clarifying the thermal acclimation mechanisms in corals using molecular techniques.
