Genetic Rescue of Australia's Arid Zone Plants. Many Australian arid zone plant species have been severely damaged by grazing, loss of pollinators and other impacts and cannot survive without urgent intervention. Some exist as small fragmented populations with too little genetic variation to reproduce or adapt to further environmental change. We propose to combine surveys of genetic (DNA) diversity and the reproductive status of populations in order to identify species that could be saved by a ....Genetic Rescue of Australia's Arid Zone Plants. Many Australian arid zone plant species have been severely damaged by grazing, loss of pollinators and other impacts and cannot survive without urgent intervention. Some exist as small fragmented populations with too little genetic variation to reproduce or adapt to further environmental change. We propose to combine surveys of genetic (DNA) diversity and the reproductive status of populations in order to identify species that could be saved by a process of ‘genetic rescue’. Genetic rescue will involve experimental pollinations to produce highly fit seedlings and later transplanting of these seedlings to augment genetically deficient populations.

Changing water availability and the conservation of wide-ranging species. This project aims to examine the factors that influence conservation in multiple-use zones, using a functional habitat approach to study hollow-dependent black-cockatoos and parrots in the jarrah forest of south-western Australia as a model system. It will focus on how water availability influences landscape use, and its potential as a management tool, and use this information to effectively conserve wide-ranging species in multiple-use landscapes in a changing climate. The project is anticipated to reduce the negative effects of competing land uses on biodiversity and improve the efficiency of conservation and landscape management.Read moreRead less

Summary
Monitoring coral reef health from space: how herbivore behaviour alters reef structure. This research seeks to understand how both fishing and marine reserves can shape coral reef landscapes by changing the way herbivores behave while foraging for food. It will use an innovative approach combining ecological theory with satellite imagery, resulting in a predictive tool for resource managers both in Australia and globally.
Effects of fire on the reproductive ecology of terrestrial orchids and on their pollinators in fragmented landscapes of southern Australia. This project will combine traditional plant and insect ecology with advanced molecular techniques to ascertain the effects of fire management on terrestrial orchids and their pollinators in fragmented landscapes. This will improve our understanding of the Australian biota and improve management and conservation of terrestrial orchids.
Diagnosing coral health tipping points under accelerating coastal hypoxia. This project aims to unlock the role hypoxia plays in shaping the healthy functioning of corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs and amplifying hypoxia exposure, yet we have no knowledge of the oxygen thresholds that sustain ‘normal’ coral functioning, or the mechanisms corals’ employ to tolerate hypoxia. This project will couple advanced oxyg ....Diagnosing coral health tipping points under accelerating coastal hypoxia. This project aims to unlock the role hypoxia plays in shaping the healthy functioning of corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs and amplifying hypoxia exposure, yet we have no knowledge of the oxygen thresholds that sustain ‘normal’ coral functioning, or the mechanisms corals’ employ to tolerate hypoxia. This project will couple advanced oxygen sensing, metabolic physiology and functional genomics techniques to transform our understanding of how corals and their associated microbial communities respond to reduced oxygen conditions, which is essential to improve coral reef ecosystem management.Read moreRead less

Ecophysiology and evolution of sleep and adaptive sleeplessness. The function of sleep is enigmatic, even though the treatment of costly sleep disorders requires an understanding of the function that sleep performs. This project approaches this enigma with the comprehensive study of sleep in diverse animals to examine ecological-induced plasticity and evolution of sleep. Using innovative technologies in real-world situations, this project will spearhead the study of sleep ecophysiology to identi ....Ecophysiology and evolution of sleep and adaptive sleeplessness. The function of sleep is enigmatic, even though the treatment of costly sleep disorders requires an understanding of the function that sleep performs. This project approaches this enigma with the comprehensive study of sleep in diverse animals to examine ecological-induced plasticity and evolution of sleep. Using innovative technologies in real-world situations, this project will spearhead the study of sleep ecophysiology to identify animals that are resilient to the negative effects of sleep loss, and will determine whether the evolution of new types of animal was associated with the co-evolution of new types of sleep. The outcomes will have wide-ranging implications for our view of sleep function, prescriptions for an optimal amount of sleep and human health and wellbeing.Read moreRead less

410 million years of stomatal evolution: key innovations in the transition from passive valves to active pores. Central to the supremacy of seed plants was the evolution of active, metabolic control of the stomata; the pores that regulate both plant productivity and water loss. However, little is known about the transition from passive control of stomata in seedless plants to active stomatal control in seed plants. This project will identify the key physiological and genetic innovations that und ....410 million years of stomatal evolution: key innovations in the transition from passive valves to active pores. Central to the supremacy of seed plants was the evolution of active, metabolic control of the stomata; the pores that regulate both plant productivity and water loss. However, little is known about the transition from passive control of stomata in seedless plants to active stomatal control in seed plants. This project will identify the key physiological and genetic innovations that underpinned the evolution of stomatal control over the past 410 million years. Understanding these evolutionary innovations will offer important insights into stomatal function in seed plants, as well as informing models of global productivity and water use through time, with benefits for Australian agriculture and natural resource management.Read moreRead less

This project aims to resolve how entire ecological communities respond to global warming and identify the mechanisms that underpin these responses. Combining manipulations of marine invertebrate communities with assays of energy use, the project expects to reveal emergent effects that cannot be predicted from responses of individual species. The expected outcome is a mechanistic understanding of how warming affects resource use of entire communities that will increase our capacity to predict the consequences of climate change on food-web stability and productivity. These findings should reveal how species interactions alter energy use and invasion risk which is vital to manage ecosystems in a warmer world.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.
The role of mycorrhizal fungi in the nutrition of temperate terrestrial orchids. This project addresses the role of external mycelial systems in the carbon and mineral nutrition of temperate terrestrial orchids. The project will determine the processes of nutrient transfer in the protocorm and adult phases of development across a range of terrestrial temperate orchids to inform conservation and restoration efforts.
