Manipulative tests of metabolic theory. This project aims to take a new interdisciplinary approach to understanding how energy flows through individuals, populations, communities, and ecosystems. The project expects to develop a new framework for understanding the function of biological systems, bringing together the fields of physiology, ecology, and evolutionary biology, generating research publications, and training students in interdisciplinary research. The proposed research is anticipated ....Manipulative tests of metabolic theory. This project aims to take a new interdisciplinary approach to understanding how energy flows through individuals, populations, communities, and ecosystems. The project expects to develop a new framework for understanding the function of biological systems, bringing together the fields of physiology, ecology, and evolutionary biology, generating research publications, and training students in interdisciplinary research. The proposed research is anticipated to provide a means for understanding how management interventions can alter energy flows in biological systems, bringing benefits across the areas of climate change adaptation, conservation science, agriculture and aquaculture, and fisheries management.Read moreRead less
The evolution of biological scaling. This project aims to understand why so few biological traits scale proportionally with body size. In contrast to previous mechanistic studies of this longstanding question, the problem will be approached from an evolutionary viewpoint, using artificial selection to engineer animals in which biological scaling laws are either broken or enhanced. By measuring the consequences of this for fitness, the project will provide a new understanding of how organismal si ....The evolution of biological scaling. This project aims to understand why so few biological traits scale proportionally with body size. In contrast to previous mechanistic studies of this longstanding question, the problem will be approached from an evolutionary viewpoint, using artificial selection to engineer animals in which biological scaling laws are either broken or enhanced. By measuring the consequences of this for fitness, the project will provide a new understanding of how organismal size and physiology evolve in nature. The approach should provide significant benefits to our understanding of the role of genetic constraints in hindering or facilitating biological adaptation, furthering our understanding of the capacity of animals to respond to environmental change.Read moreRead less
The evolution of breathing patterns in animals. Although breathing is usually regarding as a continuous process, many species voluntarily hold their breath for up to several hours at a time. This pattern of periodic breathing is shown by a range of animals including mammals, reptiles, and insects, yet the reasons why they hold their breath is unknown. This project will examine the evolution of breathing patterns in the context of climate and atmospheric conditions. The outcomes of this project w ....The evolution of breathing patterns in animals. Although breathing is usually regarding as a continuous process, many species voluntarily hold their breath for up to several hours at a time. This pattern of periodic breathing is shown by a range of animals including mammals, reptiles, and insects, yet the reasons why they hold their breath is unknown. This project will examine the evolution of breathing patterns in the context of climate and atmospheric conditions. The outcomes of this project will provide insight into the evolution of fundamental characteristic of animals (breathing), describe the role of climate in shaping how animals breathe, and demonstrate how animals will cope with climate change.Read moreRead less
Why are fish shrinking as the climate warms? This project aims to uncover the mechanisms behind the temperature-size rule, a phenomenon causing fishes and other aquatic organisms to decline in size as the climate warms. Drawing on multidisciplinary expertise to test three competing theories, this project expects to identify the fundamental processes driving the temperature-size rule phenomenon. Expected outcomes include improved models to forecast the effects of global warming on fish and fisher ....Why are fish shrinking as the climate warms? This project aims to uncover the mechanisms behind the temperature-size rule, a phenomenon causing fishes and other aquatic organisms to decline in size as the climate warms. Drawing on multidisciplinary expertise to test three competing theories, this project expects to identify the fundamental processes driving the temperature-size rule phenomenon. Expected outcomes include improved models to forecast the effects of global warming on fish and fisheries. The new knowledge and predictive power should be of direct benefit to natural resource managers in the continuing effort to mitigate the negative impacts of climate change. This will guide policy and management decisions by enabling more accurate forecasts of the impacts of climate change on wild and cultured fishes.Read moreRead less

Summary
Pre-natal communication in adaptation to hot climate. This project aims to reveal how birds programme their offspring for a warming world, by communicating acoustically with their embryos. Most animals, including humans, can hear external sounds before birth, but it is not known what function this plays. An Australian bird calls to its eggs at high ambient temperatures, which alters nestling growth and survival. This project will show the physiological effects involved and the consequences for a ....Pre-natal communication in adaptation to hot climate. This project aims to reveal how birds programme their offspring for a warming world, by communicating acoustically with their embryos. Most animals, including humans, can hear external sounds before birth, but it is not known what function this plays. An Australian bird calls to its eggs at high ambient temperatures, which alters nestling growth and survival. This project will show the physiological effects involved and the consequences for adaptation to heat in wild birds. This project will elucidate whether the global reduction in animal body size is an adaptive response to rising temperatures, and research the therapeutic benefits of pre-natal sounds.Read moreRead less
