Summary
Autonomous benthic observing system. This project seeks to improve our ability to monitor marine habitats and characterise their variability by enhancing the Integrated Marine Observing system (IMOS) Autonomous Underwater Vehicle (AUV) Facility. The new AUV infrastructure will reduce operating costs, increase robustness of the sampling effort and insure continued operation for the next decade.
When fire and water mix: do carbon dioxide-related water savings drive woody plant thickening and fire dynamics in a grassy woodland? Australia's woodland landscapes have experienced widespread shrub expansion in the last century due to changes in fire, grazing and atmospheric carbon dioxide. This project will endevour to fill critical gaps in the nexus between carbon dioxide-induced effects on vegetation and fire disturbance to help explain this phenomenon and help manage Australian woodlands i ....When fire and water mix: do carbon dioxide-related water savings drive woody plant thickening and fire dynamics in a grassy woodland?

A multi-institutional environmental radioactivity research centre. 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.

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

Summary
Free ocean carbon enrichment infrastructure for the Southern Ocean: measuring impacts of ocean acidification on biological communities. As the amount of carbon dioxide has risen in the atmosphere there has been a corresponding rise of carbon dioxide going into the ocean, changing its chemistry and making it more acidic. The project will conduct the first polar region carbon dioxide enrichment experiment to assess the vulnerability of polar organisms to continuing carbon dioxide emissions.
Satellite tracking of health threats from grass pollen exposure. This project aims to discover why pollen exposure has increased since the 1960s. Grass pollens are the main environmental allergen source in Australia and the primary cause of allergic diseases. This project will investigate the ecological causes of changing pollen allergen exposures through integrating 40 years of satellite data, field phenology cameras, and pollen traps that track grass pollen sources, their evolution and impact ....Satellite tracking of health threats from grass pollen exposure.

This project will investigate the ecological causes of changing pollen allergen exposures through integrating 40 years of satellite data, field phenology cameras, and pollen traps that track grass pollen sources, their evolution and impact areas. The outcomes are expected to advance knowledge of environmental drivers and enable more accurate pollen forecasts that alleviate the medical and socioeconomic burden of allergic diseases, estimated to cost 30 billion dollars.Read moreRead less
Future fisheries under climate change: the missing role of zooplankton. This project aims to develop the first global ecosystem model with a more realistic representation of zooplankton. Fish are the main source of protein for 3 billion people, yet fish catches are declining. Current models of future fish biomass under climate change do not consider the complex role that zooplankton play in transferring energy from phytoplankton to fish. By resolving the link between phytoplankton and fish, this ....Future fisheries under climate change: the missing role of zooplankton. This project aims to develop the first global ecosystem model with a more realistic representation of zooplankton. Fish are the main source of protein for 3 billion people, yet fish catches are declining. Current models of future fish biomass under climate change do not consider the complex role that zooplankton play in transferring energy from phytoplankton to fish. By resolving the link between phytoplankton and fish, this project will vastly improve estimates of future global fisheries production and regional variation. Such knowledge is vital for future food security in Australia and globally, and also to understand the role of zooplankton in carbon export in the ocean.Read moreRead less

Summary
Critical regions and network connectivity of coral reef ecosystems. This project aims to measure the degree of connectivity between isolated reefs in Australia's Coral Sea and the Great Barrier Reef and identify the biological and environmental mechanisms that enhance management strategies or mitigate against disturbances. The movement of individuals in fragmented landscapes plays a central role in the ecology and evolution of species.

This project aims to measure the degree of connectivity between isolated reefs in Australia's Coral Sea and the Great Barrier Reef and identify the biological and environmental mechanisms that enhance management strategies or mitigate against disturbances. The movement of individuals in fragmented landscapes plays a central role in the ecology and evolution of species. The project seeks to measure connectivity at multiple scales and identify critical regions for the design of networks of marine protected areas. This is anticipated to improve our understanding of connectivity in marine seascapes and benefit management of important fishery species and current efforts in coral reef conservation.Read moreRead less

Summary
Generalising a root-water uptake mechanism for successful land surface modelling. Understanding root functioning in Australian savanna ecosystems is critically important for successful resource management but such understanding is not represented in land surface models (LSMs). This project will incorporate root functioning into LSMs and improve our ability to manage water and carbon natural resources in a changing climate.

To reduce the uncertainties in estimating and predicting vegetation biomass and to aid in the development of climate change strategies, this project will formulate and explore the first detailed long term aboveground vegetation biomass carbon record for Australia using a series of satellite passive microwave instruments. The spatiotemporal variation in biomass carbon over past decades will be investigated to better understand how it responds to changing climate and human activities. Such information will allow more accurate estimation of future vegetation dynamics and carbon storage. Moreover, an enhanced bushfire danger index that incorporates aboveground biomass information will be developed to more precisely predict the potential damage.Read moreRead less
Ecophysiological limitations that affect water and carbon balance within large tree canopies: a comparative investigation.

Supply of water to forest canopies is a major control of hydrological, atmospheric and biotic processes that impinge on groundwater stability, catchment yield, the fate of pollutants and plant productivity. Fundamental aspects of water transport and distribution within plant tissues remain obscured by conflicting experimental data and conflicting theoretical models that describe physiological functioning.
Potential hydraulic constraints to the exchange of water and carbon between leaf and atmosphere require investigation before accurate models and informed decisions can be made with respect to the role of forests in biosphere-atmosphere processes. I will use large trees to investigate physiological and morphological determinants of hydraulic function and consider relationships between tree size, water requirements and water supply.
This project will foster comparative analyses of hydraulic functioning in large angiosperm and conifer species to elucidate universal principles that relate form to function and explain relationships between trees and their environment.
