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
Responses of reptiles to fluctuating thermal environments: behaviour or biochemistry? I propose a conceptual shift in the way thermal physiology of reptiles is interpreted, questioning the predominant role of behaviour in reptilian thermoregulation. I will test the hypothesis that changes in cellular biochemistry are an important mechanism by which reptiles respond to environmental fluctuations. I will determine the relationship between metabolic enzyme activity and performance functions, and ....Responses of reptiles to fluctuating thermal environments: behaviour or biochemistry? I propose a conceptual shift in the way thermal physiology of reptiles is interpreted, questioning the predominant role of behaviour in reptilian thermoregulation. I will test the hypothesis that changes in cellular biochemistry are an important mechanism by which reptiles respond to environmental fluctuations. I will determine the relationship between metabolic enzyme activity and performance functions, and the results may call for a re-assessment of current concepts such as the notion that reptiles must achieve "preferred" body temperatures to maintain performance.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. 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 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
Of birds and bees: membrane lipids and the determination of maximum lifespan. The underlying mechanisms that determine why different animals have different maximum lifespans are unknown. Why do queen bees live for years but the genetically-identical workers bees live for only weeks? Similarly, to understand why birds live much longer than similar-sized mammals will give immense insight into the processes that cause ageing. Understanding the aging process in animals will have significant implicat ....Of birds and bees: membrane lipids and the determination of maximum lifespan. The underlying mechanisms that determine why different animals have different maximum lifespans are unknown. Why do queen bees live for years but the genetically-identical workers bees live for only weeks? Similarly, to understand why birds live much longer than similar-sized mammals will give immense insight into the processes that cause ageing. Understanding the aging process in animals will have significant implications for human health as the biggest risk factor for most diseases is age. Such understanding will help to cope with the worldwide problems of an aging population.Read moreRead less
Neurons and neurotransmitters that control the apnoeic response to irritation of the larynx. Normal function of the larynx enables breathing, cough, singing, speech and many other normal functions. This project will reveal how nerves in the brain coordinate to achieve these many functions; in particular the way that breathing stops if fluid or smoke enters the larynx.
Nutritional and bacterial influences on gut and peripheral homeostasis. Nutritional and bacterial influences on gut and peripheral homeostasis. This project aims to understand the role of macronutrients on gut homeostasis. While the understanding of what factors affect gut homeostasis is still in its infancy, scientists know that its disruption contributes to a broad range of inflammatory diseases, including type 1 diabetes and asthma.

Nutritional and bacterial influences on gut and peripheral homeostasis. This project aims to understand the role of macronutrients on gut homeostasis. While the understanding of what factors affect gut homeostasis is still in its infancy, scientists know that its disruption contributes to a broad range of inflammatory diseases, including type 1 diabetes and asthma. This project will determine the role of specific macronutrients on gut microbiota, gut epithelium, and immunity in mice, and the receptors involved. This research could ultimately lead to significant decreases in the cost of healthcare.Read moreRead less

This project aims to investigate the role of maternal gut microbiota on foetal immune development, revealing the interaction of gut microbiota-host immunity at the early stages of new life. Significantly, the research will examine the time window when microbiota by-products from the mother reach the foetus and affect the development of immunity. Maternal by-products will be identified using cutting-edge methods to unravel the complex systems interactions in the developmental process. Outcomes include new fundamental knowledge about maternal gut microbiota composition and its relationship to the growing foetus, with benefits in informing pregnant women about their lifestyle choices, particularly their dietary habits, during pregnancy.

Design of the cardiovascular system of living and fossil vertebrates. This project aims to understand how the heart and blood vessels evolved in mammals, birds, reptiles and fish to achieve efficiency. The heart is the most important organ for life. The project will study the structure and function of vertebrate animals’ hollow and spongy hearts to show how energetics shaped their evolution. It will measure arterial holes in bone to gauge brain and bone metabolism, which opens up a new way to me ....Design of the cardiovascular system of living and fossil vertebrates. This project aims to understand how the heart and blood vessels evolved in mammals, birds, reptiles and fish to achieve efficiency. The heart is the most important organ for life. The project will study the structure and function of vertebrate animals’ hollow and spongy hearts to show how energetics shaped their evolution. It will measure arterial holes in bone to gauge brain and bone metabolism, which opens up a new way to measure metabolism in extinct animals directly from fossils, rather than by inference from living relatives. The expected outcome is to correlate cardiovascular design and metabolic rates of organs.Read moreRead less

Interactions between the early environment and the genetic regulatory program of the early embryo have major consequences for the development of individuals. The aim of this Network is to harness the resources of leading researchers from the previously distinct disciplines of developmental biology and developmental physiology to better understand developmental regulatory networks and how environmental factors impinge on them. The formation of such a Network is unique, timely and strategic in that it will generate new insights into the mechanisms by which events in early life determine the risk of adverse outcomes in perinatal and adult life.Read moreRead less
Is FGF21 the master regulator of protein intake? The project plans to bring together two major, rapidly growing disciplines – nutritional geometry and metabolic signalling – to address a topic of fundamental biological significance: the regulation of protein intake. A specific capacity to regulate protein intake has been shown for organisms spanning slime moulds to humans, yet the controlling mechanisms remain elusive. The project aims to test the hypothesis that fibroblast growth factor 21, rel ....Is FGF21 the master regulator of protein intake? The project plans to bring together two major, rapidly growing disciplines – nutritional geometry and metabolic signalling – to address a topic of fundamental biological significance: the regulation of protein intake. A specific capacity to regulate protein intake has been shown for organisms spanning slime moulds to humans, yet the controlling mechanisms remain elusive. The project aims to test the hypothesis that fibroblast growth factor 21, released from the liver under low protein nutrition, is a master regulator of protein intake. Understanding the mechanisms of protein appetite may have implications for organismal biology, understanding social interactions, the structure of food webs and the health and welfare of food and companion animals and humans.Read moreRead less
