Summary
Establishment of a confocal/multiphoton microscope for imaging of living systems. This facility will allow us to study the dynamic changes in living systems, from the smallest unicellular organisms in the ocean through to the sophisticated neural networks of the living brain. Not only will this imaging facility allow us to understand how living systems work, we will also be able to explore the dynamic changes that underlie human disease and injury.
The role of dopamine in the regulation of worker sterility in the honey bee. This project will open new doors into the knowledge of honey bees' sterility. We will not only show that certain genes control honey bee sterility but also that there is interactions between these genes and environmental cues such as the pheromones released by the queen. The project will provide significant material for a better understanding of honey bees society.

This project will open new doors into the knowledge of honey bees' sterility. We will not only show that certain genes control honey bee sterility but also that there is interactions between these genes and environmental cues such as the pheromones released by the queen. The project will provide significant material for a better understanding of honey bees society. Honey bees remain the most important pollinator world wide, and their conservation is a major concern both to agriculturalists and the general public. The project will be of immense scientific interest, and likely to be regarded as a major breakthrough. The project will also foster a strong intellectual collaboration between New Zealand and Australia.Read moreRead less

The role of early life history on the survival of coral reef fishes - opening the Black Box. A fundamental unanswered question in marine ecology and fisheries management is - what influences the number of individuals that survive the larval phase to join a reef population? Theoretical studies show that small changes in the quality of offspring can lead to large changes in the numbers surviving the larval phase. What aspects of offspring quality determine who survives is largely unknown. We use ....The role of early life history on the survival of coral reef fishes - opening the Black Box. A fundamental unanswered question in marine ecology and fisheries management is - what influences the number of individuals that survive the larval phase to join a reef population? Theoretical studies show that small changes in the quality of offspring can lead to large changes in the numbers surviving the larval phase. What aspects of offspring quality determine who survives is largely unknown. We use a multidisciplinary approach to explore what influences the quality of offspring spawned by adults, and whether offspring traits prior to or at hatching determine the identity of individuals that survive to join the reproductive population.Read moreRead less
Regenerating lizard tails: A model for understanding the process of lymphangiogenesis. In humans, impaired lymphatic drainage in limbs causes the debilitating swelling termed lymphoedema. Lymphoedema affects 500,000,000 people worldwide. In the developed world lymphoedema predominantly results from surgery for cancer, and occurs in approximately 25% of breast cancer patients. We will examine lymph vessel regeneration (lymphangiogenesis) in a naturally regenerating, complex structure (the lizard ....Regenerating lizard tails: A model for understanding the process of lymphangiogenesis. In humans, impaired lymphatic drainage in limbs causes the debilitating swelling termed lymphoedema. Lymphoedema affects 500,000,000 people worldwide. In the developed world lymphoedema predominantly results from surgery for cancer, and occurs in approximately 25% of breast cancer patients. We will examine lymph vessel regeneration (lymphangiogenesis) in a naturally regenerating, complex structure (the lizard tail), to describe the regrowth process and determine the abundance, location, functional properties and molecular control of the new lymphatics. Furthermore, if reptilian lymphatic growth factors can promote lymphangiogenesis in mammals, we can design novel therapeutic approaches using reptilian ligands to promote lymphangiogenesis in lymphoedematous human tissues.Read moreRead less
Inhibitory control of retinal sensitivity. We will determine how the nerve cells that carry information from the eye to the brain are always able to provide signals despite very different environments; daylight, fog and night. Knowledge of how nerve cells achieve this rapid learning is important for any understanding of brain function; it is fundamental if we are to develop machines that see or that help restore vision in humans. The project will provide the world's first look at the synaptic ph ....Inhibitory control of retinal sensitivity.

Knowledge of how nerve cells achieve this rapid learning is important for any understanding of brain function; it is fundamental if we are to develop machines that see or that help restore vision in humans. The project will provide the world's first look at the synaptic physiology that underpins all visual perception, helping to bring Australia back to the forefront of research in this field. This new collaboration between two successful researchers will attract top quality students and researchers from Australia and abroad and be published in major journals.Read moreRead less
Brain temperature regulation in mammals: mechanisms and consequences. Mammals detect increases in body temperature predominantly in the brain. Counterintuitively many mammals selectively cool the brain during heat stress, which appears to defeat the mechanism for inducing cooling responses. We intend to investigate this apparent anomaly which we believe is concerned with optimizing water use in hot conditions. We will further investigate the source of water for evaporative cooling by panting and ....Brain temperature regulation in mammals: mechanisms and consequences. Mammals detect increases in body temperature predominantly in the brain. Counterintuitively many mammals selectively cool the brain during heat stress, which appears to defeat the mechanism for inducing cooling responses. We intend to investigate this apparent anomaly which we believe is concerned with optimizing water use in hot conditions. We will further investigate the source of water for evaporative cooling by panting and discover if there has been convergent evolution in thermoregulatory strategies in the eutherian and marsupial lineages. The data we collect will be used to support a new model for thermoregulation in mammals.

Epigenetic Regulation of Fetal and Placental Development. Perturbations of the environment of the early embryo can alter fetal and placental growth. The mechanisms by which the early environment alters development of the fetal adrenal-placental axis are unknown. This axis coordinates fetal growth and development to ensure a successful transition from intra- to extrauterine life. We propose a novel role for the epigenetic regulation of imprinted genes in the activation of the fetal adrenal and in ....Epigenetic Regulation of Fetal and Placental Development. Perturbations of the environment of the early embryo can alter fetal and placental growth. The mechanisms by which the early environment alters development of the fetal adrenal-placental axis are unknown. This axis coordinates fetal growth and development to ensure a successful transition from intra- to extrauterine life. We propose a novel role for the epigenetic regulation of imprinted genes in the activation of the fetal adrenal and in placental growth and differentiation. This proposal extends the 'genetic conflict' hypothesis of the role of imprinted genes beyond its current focus on the regulation of fetal nutrient supply and demand.Read moreRead less

The escalating problems associated with obesity are immense. These effects contribute to a global epidemic that now eclipses both infectious diseases and (ironically) undernutrition in its proportions. The effects of disorders of thirst are less apparent but potentially devastating albeit on a smaller scale. The elderly and psychotic in the community have impaired thirst mechanisms which impacts on their life in a dramatic way particularly during prolonged hot weather. The aims of these experiments are to understand the basic brain mechanisms that underpin these drives. This understanding will have far reaching repercussions for the community both in terms of promoting good health and in preventative health care.
