Pheromone evolution and ecology in insects on intra- and inter-specific scales. The study of pheromones is important because so many insect pests use them as part of their reproductive life cycle, increasing their potential to cause damage to crops and other natural products. My research will improve our understanding of the evolution of pheromones and communication by smell, a subject that has been largely neglected by evolutionary biologists. More specifically, by identifying the ecological fa ....Pheromone evolution and ecology in insects on intra- and inter-specific scales. The study of pheromones is important because so many insect pests use them as part of their reproductive life cycle, increasing their potential to cause damage to crops and other natural products. My research will improve our understanding of the evolution of pheromones and communication by smell, a subject that has been largely neglected by evolutionary biologists. More specifically, by identifying the ecological factors that influence pheromone evolution, the research will help to assess the long-term consequences of the control measures currently used against such pests and, in particular, will have direct applications to the prevention of damage to Australian pine plantations by the invasive five-spined bark beetle, Ips grandicollis.

The evolution of elaborate antennae in insects. This project will address several neglected but fundamental issues in the field of chemical communication and insect diversity. These include the evolutionary importance of receptor structures in a communication system, and the basis of diversity in one of the most defining characteristics of insects: antennae. The moth species in the proposed experiments are commercial pests of crops and therefore understanding of the evolutionary processes shapin ....The evolution of elaborate antennae in insects. This project will address several neglected but fundamental issues in the field of chemical communication and insect diversity. These include the evolutionary importance of receptor structures in a communication system, and the basis of diversity in one of the most defining characteristics of insects: antennae. The moth species in the proposed experiments are commercial pests of crops and therefore understanding of the evolutionary processes shaping their communication systems and mating behaviour will contribute to better predictive knowledge of the effects of control measures used against them. The project will also involve international collaboration to learn and develop new a technique in the analysis of pheromone communication. Read moreRead less

Sexual signalling and parental care: A life-history perspective. I will use a fish, the Australian desert goby, to gain pivotal insights into male reproductive investment. Under-appreciated as potential study subjects, desert gobies are ideal because males must make important reproductive decisions regarding how much effort to spend on mate attraction and parental care but, importantly, they must do so within the constraints imposed by desert-living. The likely impact of my work in the field of ....Sexual signalling and parental care: A life-history perspective. I will use a fish, the Australian desert goby, to gain pivotal insights into male reproductive investment. Under-appreciated as potential study subjects, desert gobies are ideal because males must make important reproductive decisions regarding how much effort to spend on mate attraction and parental care but, importantly, they must do so within the constraints imposed by desert-living. The likely impact of my work in the field of behavioural ecology will improve Australia's research capacity and profile. By using an Australian study species, my research will also raise awareness and understanding of extraordinary fishes living in habitats vulnerable to human impact. Read moreRead less
The evolution of parental care in leeches: costs and benefits in a clade of hermaphroditic, invertebrate ectotherms. Parental care is a basic element of reproduction in many species. Nearly everything we know about parental care comes from study of vertebrates, especially birds and mammals. Leech is synonymous with exploitation, but many of these annelid worms are devoted parents. Because they differ dramatically from most vertebrates, leeches present an excellent, but as yet unused, opportunity ....The evolution of parental care in leeches: costs and benefits in a clade of hermaphroditic, invertebrate ectotherms. Parental care is a basic element of reproduction in many species. Nearly everything we know about parental care comes from study of vertebrates, especially birds and mammals. Leech is synonymous with exploitation, but many of these annelid worms are devoted parents. Because they differ dramatically from most vertebrates, leeches present an excellent, but as yet unused, opportunity to test our theories and understanding of the evoluton of parental care. We will examine the evolution of degrees of care and sibling competition in leech families, and use molecular markers to better understand the genetic structure of populations of these invertebrates.Read moreRead less

Evolutionary signficance of sexual conflict in orb-web spiders. Multiple mating by females creates intense competition between ejaculates over the fertilisation of her eggs, and has a profound influence on male and female life history and mating strategies. In orb-web spiders, sexual cannibalism creates further conflicts of interest because the male may forfeit future matings. This project examines how life-history and mating strategies interact in these spiders, by identifying the mechanisms t ....Evolutionary signficance of sexual conflict in orb-web spiders. Multiple mating by females creates intense competition between ejaculates over the fertilisation of her eggs, and has a profound influence on male and female life history and mating strategies. In orb-web spiders, sexual cannibalism creates further conflicts of interest because the male may forfeit future matings. This project examines how life-history and mating strategies interact in these spiders, by identifying the mechanisms that determine the outcome of sperm competition; the selection pressures favouring sexual size dimorphism and male size variation; the influence of sexual cannibalism on male mating strategies; and the relationship between female feeding history and her mating behaviour.Read moreRead less
