Reproductive plasticity and climate change: insights from an opportunistic breeder. Across the globe, birds are struggling to optimise their reproductive timing and investment in a changing and unpredictable climate. This project will use the highly adaptable and opportunistic Australian zebra finch to develop an understanding of how birds tailor their behaviour and physiology to breed across a range of conditions.
Significance and mechanisms of evaporative water loss control by endotherms. This project plans to examine the novel hypothesis that mammals and birds can control and minimise their evaporative water loss in dry environments. Water balance is fundamental for the survival of mammals and birds. As a large component of total water loss, evaporative water loss is particularly critical for species in arid habitats and areas undergoing desertification and other habitat modifications. Control of water ....Significance and mechanisms of evaporative water loss control by endotherms. This project plans to examine the novel hypothesis that mammals and birds can control and minimise their evaporative water loss in dry environments. Water balance is fundamental for the survival of mammals and birds. As a large component of total water loss, evaporative water loss is particularly critical for species in arid habitats and areas undergoing desertification and other habitat modifications. Control of water loss is a previously unappreciated ability in mammals and birds. Determining the mechanistic basis for evaporative homeostasis would fundamentally change our knowledge of animal function, and may help us to predict and understand the effects of environmental change on survival and distribution limits for Australian fauna.Read moreRead less
Living in a changing climate: the impacts of temperature during aestivation on burrowing frogs. Although arid zones of Australia are characterised by extremes of temperature, little is known about the thermal ecology of frogs inhabiting these regions. This project will determine the effects of temperature on the physiology of an arid-adapted frog and determine whether likely increases in global temperatures will impact its survival.

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
