The function and maintenance of aggressive mimics: the cleaner fish - fangblenny system. Mimicry is an important biological phenomenon, which is studied extensively by scientists. However, only 5% of papers that were published on mimicry systems in the last five years were from Australian institutes, yet mimicry is ubiquitous in Australia. Therefore, this study will enhance the recognition of Australian research on the international stage in mimicry studies, animal communication systems and beha ....The function and maintenance of aggressive mimics: the cleaner fish - fangblenny system. Mimicry is an important biological phenomenon, which is studied extensively by scientists. However, only 5% of papers that were published on mimicry systems in the last five years were from Australian institutes, yet mimicry is ubiquitous in Australia. Therefore, this study will enhance the recognition of Australian research on the international stage in mimicry studies, animal communication systems and behavioural ecology. This work will aid communication of biology to the general public, as mimicry is a celebrated example of Darwinian adaptation and stories about coral reefs are interesting and intuitive. This study will also provide empirical data to support theoretical development of mimicry theory. Read moreRead less

The benefits of sociality: understanding the relationship between cooperation, cognition and fitness. Cooperation may present unique cognitive challenges. Individuals perform behaviours that provide fitness benefits to others, exposing themselves to risk. The need to monitor the behaviour of group members, recognise suitable cooperative partners, and make corresponding behavioural adjustments to maximize the benefits of cooperation, may therefore be an important driver of social evolution. The r ....The benefits of sociality: understanding the relationship between cooperation, cognition and fitness. Cooperation may present unique cognitive challenges. Individuals perform behaviours that provide fitness benefits to others, exposing themselves to risk. The need to monitor the behaviour of group members, recognise suitable cooperative partners, and make corresponding behavioural adjustments to maximize the benefits of cooperation, may therefore be an important driver of social evolution. The relevance of understanding the relationship between cognition and cooperation is in how it affects the fitness of individuals and the stability of cooperation. This project aims to unveil this relationship by conducting one of the first comprehensive studies of the selective benefits of cognitive ability in a wild, cooperative bird species.Read moreRead less
The origins of gender. This project intends to address how the evolutionary phenomena of intra-sexual competition and inter-sexual conflict interact with economic circumstances to shape gendered behaviour and attitudes. These phenomena are important in evolution, economics, psychology and sociology, with implications for the economy and for the welfare of women and men. The project predicts that gender-related culture arises, partially, out of mating market dynamics. The research crosses traditi ....The origins of gender. This project intends to address how the evolutionary phenomena of intra-sexual competition and inter-sexual conflict interact with economic circumstances to shape gendered behaviour and attitudes. These phenomena are important in evolution, economics, psychology and sociology, with implications for the economy and for the welfare of women and men. The project predicts that gender-related culture arises, partially, out of mating market dynamics. The research crosses traditional boundaries between biology and economics to investigate the forces giving rise to gendered behaviour and resulting patterns of marriages, violence, political preferences and occupational choices. The project may provide new insights into the links between gender and violence, within-family conflicts, and gender roles in the home and workplace.Read moreRead less
Biogeography of avian mating systems: polyandry, reverse-plumage dimorphism, and sexual selection in Cape York and New Guinea eclectus parrots. Current sexual selection theory explains how one sex can be strongly sexually selected through competition or mate choice, or how sexual selection can push both sexes in the same direction through mutual mate choice. However, the strong and independent sexual selection in both sexes of eclectus parrot is unique amongst birds, and poses a major challenge ....Biogeography of avian mating systems: polyandry, reverse-plumage dimorphism, and sexual selection in Cape York and New Guinea eclectus parrots. Current sexual selection theory explains how one sex can be strongly sexually selected through competition or mate choice, or how sexual selection can push both sexes in the same direction through mutual mate choice. However, the strong and independent sexual selection in both sexes of eclectus parrot is unique amongst birds, and poses a major challenge to existing theory. Here I propose novel field experiments and biogeographical comparisons of populations in Cape York and New Guinea that, when combined with molecular techniques and spectro-radiometry, will identify the elements of competition and mate choice responsible for their extraordinary reverse plumage dimorphism.Read moreRead less
Sperm Competition and Sexual Selection. Competition between the sperm of two males within a single female has had profound implications for the evolution of male reproductive biology and behaviour. However, the reasons why females should mate with more than one male and thus generate sperm competition remains an evolutionary puzzle. Few studies have examined sperm competition from the female perspective and indeed, female perspectives are currently the subject of considerable debate. Using in ....Sperm Competition and Sexual Selection. Competition between the sperm of two males within a single female has had profound implications for the evolution of male reproductive biology and behaviour. However, the reasons why females should mate with more than one male and thus generate sperm competition remains an evolutionary puzzle. Few studies have examined sperm competition from the female perspective and indeed, female perspectives are currently the subject of considerable debate. Using insects as models I will examine the benefits of sperm competition for females and thereby the selective pressures that favour multiple mating. Moreover, I will determine whether sexual selection can act after copulation.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
