Skin in the game: biomimetics, fitness and the springtail cuticle. This project aims to examine the relationship between cuticle (skin) properties, water balance, and fitness in springtails, key players in soil systems. Springtail cuticles are diverse, responsive, and extremely resistant to wetting by water, alcohol and other substances. Their Australian diversity has not been well explored for biomimetic new materials. This project expects to explore options for new applications in materials sc ....Skin in the game: biomimetics, fitness and the springtail cuticle. This project aims to examine the relationship between cuticle (skin) properties, water balance, and fitness in springtails, key players in soil systems. Springtail cuticles are diverse, responsive, and extremely resistant to wetting by water, alcohol and other substances. Their Australian diversity has not been well explored for biomimetic new materials. This project expects to explore options for new applications in materials science and engineering by generalising the cuticle structure-function relationship. Expected outcomes are new information to harness for industry the diversity of nature’s self-cleaning, water repellent surfaces. Significant benefits lie in potential new biomimetic manufacturing options.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.
The role of plant-soil feedback in biodiversity maintenance along fertility gradients: from patterns to mechanisms. Plants strongly modify soils and their associated biota, which in turn has important consequences for plant growth. This is known as 'plant-soil feedback'. This project will determine whether such feedback plays a role in maintaining the exceptionally high levels of plant biodiversity found in the kwongan shrublands of south-western Australia.
Facilitation of high leaf phosphorus-use efficiency by nitrate restraint. This project aims to determine the link between high phosphorus use efficiency and nitrogen metabolism in the Fabaceae, Myrtaceae and Proteaceace, the three families of plants that co-dominate the flora on the extremely phosphorus-impoverished soils of south-western Australia, a Global Biodiversity Hotspot. It is expected that the extremely high phosphorus use efficiency in these plants is inextricably linked to a low capa ....Facilitation of high leaf phosphorus-use efficiency by nitrate restraint. This project aims to determine the link between high phosphorus use efficiency and nitrogen metabolism in the Fabaceae, Myrtaceae and Proteaceace, the three families of plants that co-dominate the flora on the extremely phosphorus-impoverished soils of south-western Australia, a Global Biodiversity Hotspot. It is expected that the extremely high phosphorus use efficiency in these plants is inextricably linked to a low capacity for nitrogen uptake. An anticipated outcome is new insight into how these plants achieve highly efficient phosphorus and nitrogen use, providing new understanding into the functioning of plants in an exceptionally biodiverse ecosystem and into traits that may lead to to crops with higher fertilizer use efficiency.Read moreRead less
