Testing metabolic theories in ecology. There are striking similarities in the way plants and animals take up and use energy (metabolism), despite enormous variation in size and life-style. This project will make the first experimental comparison of the predictions of the two major theories for these broad patterns. The results will significantly progress this controversial and exciting field.
Lost at sea? Understanding adaptation and dispersal in spiny lobsters. Continual recruitment of young is fundamental to the replenishment of populations, especially when a stock is fished. Existing theory suggests that species with very long planktonic larval stages disperse widely, ensuring their genes are well mixed. However, recently identified genetic differences between populations of rock lobster challenge this paradigm and demonstrate that despite larvae mixing in the ocean for years, loc ....Lost at sea? Understanding adaptation and dispersal in spiny lobsters. Continual recruitment of young is fundamental to the replenishment of populations, especially when a stock is fished. Existing theory suggests that species with very long planktonic larval stages disperse widely, ensuring their genes are well mixed. However, recently identified genetic differences between populations of rock lobster challenge this paradigm and demonstrate that despite larvae mixing in the ocean for years, local recruitment and/or adaptation are at play. Recent developments in genomics and bioinformatics should allow this project to understand the ecological processes underpinning these genetic signatures and determine their evolutionary implications. Such findings could direct targeted rebuilding of depleted fisheries stocks.Read moreRead less
Living in a high carbon dioxide world: impacts on freshwater phytoplankton populations from elevated atmospheric carbon dioxide. This project will investigate likely changes in phytoplankton populations in reservoirs that will be caused by increases in atmospheric carbon dioxide over the next century. The project will provide water supply managers with the necessary information to plan future strategies for water treatment and operating procedures.
Muscle fibre excitability and calcium regulation in skeletal muscle of amphibians and mammals. The fundamental role of skeletal muscle is posture and movement. Essential for this is a specialised cell structure and a complex regulation of function. This project will define key aspects of muscle structure and functional regulation crucial to developing targets for improving function under stressed states such as fatigue, disease and age.
Estrogen signalling in gonadotropes. Estrogen action is a normal prerequisite for cyclic function of reproduction in the female, but little is known about how this important hormone acts in the relevant cells of the pituitary gland (gonadotropes). In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms. The information will be valuable in understanding normal reproduction, but will also form the basis of further studi ....Estrogen signalling in gonadotropes. Estrogen action is a normal prerequisite for cyclic function of reproduction in the female, but little is known about how this important hormone acts in the relevant cells of the pituitary gland (gonadotropes). In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms. The information will be valuable in understanding normal reproduction, but will also form the basis of further studies to investigate the effects of drugs that affect estrogen action and environmental estrogens.

Calcium cycling and heat generation in skeletal muscle fibres. This project aims to uncover the mechanisms that enable mammalian skeletal muscle to play a major role in generating the heat required to maintain a constant body temperature. The ability to modulate body heat played a defining role in the evolution of species, their behaviour and global distribution. How heat production occurs in resting muscle is of fundamental importance and will be defined for the first time, providing new avenu ....Calcium cycling and heat generation in skeletal muscle fibres.

Summary
Hyperpolarised gas functional lung and molecular imaging. This project will produce a polariser to generate magnetised gas for research with magnetic resonance imaging (MRI). This allows imaging of normal and abnormal lung ventilation and circulation in animal and humans. The use of these hyperpolarised gases can also be used to tag specific molecules and increase understanding of lung metabolism.
Detecting sex differences in natural selection. This project aims to develop new genomic approaches for understanding how genetic mutations can differentially affect reproductive success in males and females. Applying novel tests, this project aims to uncover previously hidden genetic conflicts between the sexes. This will provide significant benefits, such as new tools that will be broadly applicable to the wider research community, and help to answer key questions in genetics and evolutionary ....Detecting sex differences in natural selection.

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

This project aims to investigate the biological mechanisms driving the evolution of toxic cyanogenic glucosides by exploiting the natural diversity of Australian wild relatives of the crop sorghum that are adapted to different environments. Wild crop relatives are an important source of traits for improving their cultivated counterparts. Analysing the diversity and evolution of Australia’s 17 native sorghum species will provide new understanding of how plants have adapted to environmental challenges across diverse Australian environments. This should provide significant benefit by providing new resources for plant breeders to produce more climate-resilient crops.Read moreRead less
