Evolution of halophytes: a phyloinformatic approach to understanding and exploiting the traits underlying salt-tolerance in plants. Salinity is an increasing burden on the Australian economy & environment, with >2 million ha of salt-affected land, at an annual cost to agriculture over $187 million. One solution is to exploit naturally salt-tolerant plants to increase productive agricultural land and restore salt-affected environments. To do this, we must increase basic knowledge of the diversity ....Evolution of halophytes: a phyloinformatic approach to understanding and exploiting the traits underlying salt-tolerance in plants. Salinity is an increasing burden on the Australian economy & environment, with >2 million ha of salt-affected land, at an annual cost to agriculture over $187 million. One solution is to exploit naturally salt-tolerant plants to increase productive agricultural land and restore salt-affected environments. To do this, we must increase basic knowledge of the diversity & distribution of salt-tolerance. This project is the first to use DNA sequences from thousands of species to understand the evolution of salt-tolerance in order to provide the foundation for the development of new crop varieties, selection of species that can be developed for bioremediation, and identification of traits that will be profitable targets for breeding programs.

Experimental evolution of trait interactions under changed environments. This project aims to use altered light in laboratory and wild guppy populations to test directly the following questions: which traits evolve quickly or slowly and how does this depend upon their functional interactions, and how often do different solutions to the same environmental challenges evolve? The evolutionary effects of environmental change on gene regulation and functional interactions among traits are virtually u ....Experimental evolution of trait interactions under changed environments. This project aims to use altered light in laboratory and wild guppy populations to test directly the following questions: which traits evolve quickly or slowly and how does this depend upon their functional interactions, and how often do different solutions to the same environmental challenges evolve? The evolutionary effects of environmental change on gene regulation and functional interactions among traits are virtually unknown. Using evolution experiments, this project aims to explore traits with known functional links: opsin gene regulation patterns (for colour vision), colouration, and colour-based choice. It is expected that vegetation changes cause immediate environment changes, directly affecting animals’ abilities to choose mates, forage, and avoid predation.Read moreRead less
Testing evolutionary predictions about multiple unrelated traits under changed environmental conditions using visual ecology. An understanding of evolution is vital in managing the effects of environmental change. Senses determine success in survival/reproduction and environmental change affects what is sensed. This project will make and test explicit predictions about evolution under changed conditions using visual physiology, environmental parameters and evolution experiments.

The developmental and evolutionary origins of vertebrate fins and limbs. This project aims to investigate the origin of paired appendages, a major event in early vertebrate history that changed ecological opportunity and fuelled the radiation of jawed vertebrates. This project expects to generate new knowledge on the mechanism that drove this innovation, which despite over a century of debate, remains one
of the great unknowns of comparative vertebrate evolution. Expected outcomes of this projec ....The developmental and evolutionary origins of vertebrate fins and limbs. This project aims to investigate the origin of paired appendages, a major event in early vertebrate history that changed ecological opportunity and fuelled the radiation of jawed vertebrates. This project expects to generate new knowledge on the mechanism that drove this innovation, which despite over a century of debate, remains one
of the great unknowns of comparative vertebrate evolution. Expected outcomes of this project include uncovering the anatomical changes underpinning the origin of the vertebrate appendicular system. This should provide significant benefits as it will inform our own natural history and provide a paradigm for studying gene network
conservation, phylogenetic modifications, and the acquisition of novel structures.Read moreRead less

Summary
The costs of pheromone production. This project seeks to answer fundamental questions in sexual selection theory. Chemical communication plays a fundamental role in mate choice in most taxa, yet it is critically under-researched. Traditionally, the costs of pheromone production have been assumed to be low. How these ‘low-cost’ signals remain ‘honest’ remains a central question in evolutionary biology. This project intends to quantify the costs of pheromone production in two insect model systems ....The costs of pheromone production. This project seeks to answer fundamental questions in sexual selection theory. Chemical communication plays a fundamental role in mate choice in most taxa, yet it is critically under-researched. Traditionally, the costs of pheromone production have been assumed to be low. How these ‘low-cost’ signals remain ‘honest’ remains a central question in evolutionary biology. This project intends to quantify the costs of pheromone production in two insect model systems with different modes of chemical communication, and to reveal the underlying physiological mechanisms that ensure signal honesty. This project expects to advance knowledge in the fields of chemical communication and insect immunology which may provide information useful to pest management.Read moreRead less
Biogenesis of the relict plastid of Apicomplexan parasites: the role of a dynamin-related protein in apicoplast division. The Apicomplexa are a group of intracellular parasites that cause several important diseases. Most Apicomplexa contain an organelle called the apicoplast that is indispensable for their survival and that can only form through the division of pre-existing apicoplasts. This project will examine the molecular mechanisms of how this process occurs.
