This project aims to determine the physiological effects of extreme hot weather on animals’ metabolism, development, body size and cell lifespan. Body size in animals is negatively related to latitude; individuals are relatively small in hot climates. The project will test the idea that the adverse effects of heat during development constrain body size. The project will draw on physiology, endocrinology, behaviour and cell biology and study birds across Australian climates and in a temperature-controlled laboratory. The outcomes of the project will provide insight into regional variation in species vulnerabilities to climate variation and inform biodiversity management.Read moreRead less
Evolution of the mammalian baculum. This project aims to test the hypothesis that the shape of the mammalian baculum (penis bone) evolved via its stimulatory effects on females that promote reproduction. The baculum is the most morphologically divergent bone in the mammalian body. The reason for this divergence is one of the most puzzling enigmas of mammalian morphology. This project will use comparative evolutionary methods, quantitative genetics, morphometrics, behavioural analysis and techniq ....Evolution of the mammalian baculum.

The baculum is the most morphologically divergent bone in the mammalian body. The reason for this divergence is one of the most puzzling enigmas of mammalian morphology. This project will use comparative evolutionary methods, quantitative genetics, morphometrics, behavioural analysis and techniques from neurobiology and physiology to test this hypothesis. This project aims to address fundamental questions in reproductive biology.Read moreRead less
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.
Does plant phosphorus economy determine ecological status in biodiverse Australian communities? The phosphorus (P)-impoverished nature of the soils of south-western Australia has allowed the evolution of many plant species that are amazingly efficient at acquiring and utilising P. Among the most P efficient are species of the Proteaceae, which produce cluster roots. We will explore why less efficient species can co-occur with the very efficient Proteaceae. A deep and thorough understanding of th ....Does plant phosphorus economy determine ecological status in biodiverse Australian communities? The phosphorus (P)-impoverished nature of the soils of south-western Australia has allowed the evolution of many plant species that are amazingly efficient at acquiring and utilising P. Among the most P efficient are species of the Proteaceae, which produce cluster roots. We will explore why less efficient species can co-occur with the very efficient Proteaceae. A deep and thorough understanding of the mechanism determining P efficiency of these species will contribute significantly to our basic understanding of P nutrition in plants and to our understanding of the P-impoverished ecosystems of the southwest. It will also assist in developing crops that are more efficient at acquiring and/or utilising P.Read moreRead less
Adaptive function of insect cuticular lipids. Insects secrete onto their surface a cocktail of high melting-point waxes. These biological compounds have been found to be involved in communication but are also thought to protect the insect from water loss and pathogen invasion. Insects represent the most abundant group of animals on Earth. It has been suggested that the dual role of surface waxes in ecological adaptation and reproduction may be key to their remarkable divergence. However, little ....Adaptive function of insect cuticular lipids. Insects secrete onto their surface a cocktail of high melting-point waxes. These biological compounds have been found to be involved in communication but are also thought to protect the insect from water loss and pathogen invasion. Insects represent the most abundant group of animals on Earth. It has been suggested that the dual role of surface waxes in ecological adaptation and reproduction may be key to their remarkable divergence. However, little is known of the function of individual compounds within mixtures of insect waxes. Using chemical analysis, neurophysiology and whole animal performance, the aim of this project is to provide a detailed understanding of the function of insect surface wax with potential for bioinspired products.Read moreRead less
ARC Australia-New Zealand Research Network for Vegetation Function. Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ....ARC Australia-New Zealand Research Network for Vegetation Function. Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ecoinformatics and evolutionary theory. Across this span, working groups will target nine identified opportunities for breakthrough research. Each research target needs input from two or more disciplines. Together, the nine targets link across disciplines, as a network that spans from genomic to planetary scales.Read moreRead less
The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on trop ....The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on tropical reefs or rainforest communities, through careful temporal niche partitioning where reliance on other sensory systems takes over from vision and olfaction as the principal method of prey detection. This project aims to elucidate how the modern fish diversity was shaped by such significant early evolutionary events.Read moreRead less

Summary
Understanding the origin and maintenance of megadiverse plant communities. South-western Australia hosts some of the most biologically diverse plant communities on Earth, and these occur on the most ancient, nutrient-impoverished soils. By studying coastal dunes of increasing age, this project will determine how megadiverse plant communities originate during long-term ecosystem development, and how they are maintained.
