To grow or to store: Do plants hedge their bets? This project aims to resolve a long-standing question about the function of perennial plants: how much of the carbon taken up by photosynthesis is used immediately for growth, and how much is kept in reserve as insurance against future stress? This question is important to our understanding of how plants respond to stresses such as severe drought, and yet lack of data and theoretical modelling currently hampers our ability to answer it.

This project aims to resolve a long-standing question about the function of perennial plants: how much of the carbon taken up by photosynthesis is used immediately for growth, and how much is kept in reserve as insurance against future stress? This question is important to our understanding of how plants respond to stresses such as severe drought, and yet lack of data and theoretical modelling currently hampers our ability to answer it. By applying novel data analysis and modelling tools to recent experimental results, the project plans to test hypotheses for how plants allocate carbon between growth and storage in response to stress. Insights from the project may underpin better management of Australia’s vulnerable ecosystems.Read moreRead less
Linking phytoplankton to fisheries using zooplankton size spectra. This project aims to develop innovative numerical methods to understand the dynamics, carbon export, and trophic structure of zooplankton. The trophic links between phytoplankton, zooplankton and fisheries are unknown. The size- frequency distribution of zooplankton (size spectrum) is an innovative method for estimating their growth, predation and production as food for fish. Analysis of a global synthesis of zooplankton size dis ....Linking phytoplankton to fisheries using zooplankton size spectra. This project aims to develop innovative numerical methods to understand the dynamics, carbon export, and trophic structure of zooplankton. The trophic links between phytoplankton, zooplankton and fisheries are unknown. The size- frequency distribution of zooplankton (size spectrum) is an innovative method for estimating their growth, predation and production as food for fish. Analysis of a global synthesis of zooplankton size distributions from tropical to polar environments are expected to reveal these vital rates of pelagic ecosystems. The zooplankton rates will reveal, for the first time, the link between phytoplankton and fisheries, and will significantly improve ecosystem models and global assessments of environmental change.Read moreRead less

This project aims to establish an environmental radioactivity research centre, equipped with ultra-low background and high-resolution alpha and gamma spectrometry systems, radon detectors and radium delayed coincidence counters. The centre will address a critical demand in Australia for precise analysis of a large suite of natural and artificial radionuclides, which will be used as tracers and chronological tools to investigate key questions in oceanography and the mining and energy, archaeological, agricultural, and forestry sectors. The facility is expected to substantially increase expertise and training in radionuclides in Australia, and promote high-level research collaborations and outputs of both national and international significance. Major outcomes of the proposed facility include better understanding of how oceans regulate climate and improved capacity to assess effects of radiation on natural ecosystems.Read moreRead less
Optimisation of catchment management: stable isotope studies of water storage and yield. Focusing on the Cotter catchment, this project will establish how the water content of soils and tree stems regulates the amount of water used by trees in sub-catchments, and thus how much reaches streams and dams. Small areas supply most of the water yield and this project will help identify where managers should focus efforts to increase yield.
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.
Marine urban development: how can ecology inform the design of multifunctional artificial structures?

This project aims to experimentally manipulate the design of artificial structures to achieve multipurpose ecological objectives. Artificial structures such as buildings and roads have featured in terrestrial urban landscapes for many years, but have only more recently begun encroaching on aquatic environments. Most marine artificial structures lack the innovative design solutions required to mitigate their ecological impacts and provide essential ecosystem services such as pollution abatement. This project will investigate the efficacy of these designs with both classical measures of diversity and structure and novel measures of ecosystem function. The project aims to provide essential information to inform the design of future marine urban developments.Read moreRead less

The marine productivity buoy: a multi-parametric underwater profiler:
The marine productivity buoy is an innovative multi-parametric moored underwater profiler that would provide key information on phytoplankton primary productivity (PP), phytoplankton blooms, and water quality in coastal waters around Australia. The aim is to better understand changes in phytoplankton PP and abundance by synergistically using observations from the new facility made several times a day from the surface to the seafloor, and spatially extended surface observations from Earth-orbiting ocean colour satellites. Anticipated outcomes are more accurate phytoplankton PP estimates and water quality parameters in Australian coastal waters in support to research and to monitoring of these critical environments.Read moreRead less

Aquatic sources of carbon dioxide and methane are globally significant, but unknown for flooded drylands. The aim of this project is to use an innovative combination of well-integrated methodologies to determine if flooded drylands release large amounts of carbon dioxide and methane. This project is significant because this release of carbon dioxide and methane has not previously been accounted for and may change the magnitude of the global terrestrial carbon dioxide sink and account of some of the planet’s missing sources of methane. The outcomes of this project will make a significant contribution to our understanding of the global carbon cycle and earth climate system, and inform future management of these systems.
