Do cleaner-fish control infections of parasitic protozoa transmitted by gnathiid isopods and leeches? We will study a popular example of mutualism, cleaning behaviour, from a different point of view: that cleaner-fish control the parasitic protozoa of the blood of client-fish by eating their vectors. This will provide information on the biological control of vector-borne parasites and develop mathematical models that will help us understand the epidemiology of vector-borne parasites in the sea. ....Do cleaner-fish control infections of parasitic protozoa transmitted by gnathiid isopods and leeches? We will study a popular example of mutualism, cleaning behaviour, from a different point of view: that cleaner-fish control the parasitic protozoa of the blood of client-fish by eating their vectors. This will provide information on the biological control of vector-borne parasites and develop mathematical models that will help us understand the epidemiology of vector-borne parasites in the sea. Our study will provide baseline data of a parasitic disease in a wild population, information useful for managing and monitoring the health of coral reefs. With the increased aquaculture of tropical fish species in Australia, this study will benefit the fish-farming industry by providing information on the biological control of fish parasites.Read moreRead less
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
Colour vision and photoreceptors in reef fish: a model system to discover the function of double cones. Humans are visual animals and as lucky Australians we love to look at The Great Barrier Reef. This project, while rooted in the complexities of visual neurobiology, uses a recently discovered set of 4 different reef fish from the GBR to teach us more about fundamental principles in vision. These fish, diverse as damselfish and snappers, will help solve a mystery centuries old. Double cones are ....Colour vision and photoreceptors in reef fish: a model system to discover the function of double cones. Humans are visual animals and as lucky Australians we love to look at The Great Barrier Reef. This project, while rooted in the complexities of visual neurobiology, uses a recently discovered set of 4 different reef fish from the GBR to teach us more about fundamental principles in vision. These fish, diverse as damselfish and snappers, will help solve a mystery centuries old. Double cones are the commonest daytime photoreceptor in the eyes of almost all vertebrates (humans without them are exceptions) and yet nobody knows what they do. Reef fish have them, so let's ask them what they see!Read moreRead less

Effects of river plumes on nearshore ecosystems: organic matter flows and food web consequences. River plumes may subsidize nearshore food webs by exporting land-derived material and by stimulating marine phytoplankton production via nutrient delivery. Whereas previous documentation of the biological responses to plumes has been mostly limited to large rivers and to primary production, this project targets small systems that discharge directly onto open coasts, and focuses on the fate of plume ....Effects of river plumes on nearshore ecosystems: organic matter flows and food web consequences. River plumes may subsidize nearshore food webs by exporting land-derived material and by stimulating marine phytoplankton production via nutrient delivery. Whereas previous documentation of the biological responses to plumes has been mostly limited to large rivers and to primary production, this project targets small systems that discharge directly onto open coasts, and focuses on the fate of plume material. Work on carbon pathways will centre on pelagic and benthic food chains associated with plumes, and will also test whether nearshore waters and sandy beaches are coupled via onshore advection of plume material.Read moreRead less
The role of algal endosymbionts in acclimation and adaptation of reef corals to climate change. Understanding the potential of symbiotic zooxanthellae to enhance the thermal tolerance of reef corals addresses our first national Research Priority Goal aimed at the sustainable use of Australia's biodiversity.

Understanding the potential of symbiotic zooxanthellae to enhance the thermal tolerance of reef corals addresses our first national Research Priority Goal aimed at the sustainable use of Australia's biodiversity. Given current trends in global warming, such knowledge is critical to underpinning the long-term management of the Great Barrier Reef, which has significant political and socio-economic importance on local, state, national and global scales for services ranging from fisheries to ecotourism. Understanding the potential for corals to form associations with different genetic types of zooxanthellae will significantly advance current knowledge of the likelihood that animals can adapt to climate change.Read moreRead less

We propose to study pollutants such as pesticides, polychlorinated biphenyls (PCBs), and metals in sea turtles. Drs Whittier (UQ) and Henry Olszowy (Queensland Health Scientific Services) will supervise a Ph.D. student in the research. We will identify significant pollutants in Queensland, the Solomon Islands and Malaysia at sea turtle nesting and feeding grounds. We will follow the fate of chemicals in female turtles and the effects of contamination on the development of eggs and hatchlings. This information will be used to help manage sea turtle populations and to contribute to sustainable use of the animals for a growing ecotourism industry.Read moreRead less
Aquatic eye design: sharks and rays as models of underwater colour and luminance vision. Sharks are usually assumed to be colour blind. We have discovered that they may in fact see colour very well and that the eyes of different species are adapted to their particular lifestyles. Our research will help to raise the profile of sharks and portray them as animals with advanced sensory systems and complex visual behaviours rather than just dangerous killing machines. Studying the vision of sharks m ....Aquatic eye design: sharks and rays as models of underwater colour and luminance vision. Sharks are usually assumed to be colour blind. We have discovered that they may in fact see colour very well and that the eyes of different species are adapted to their particular lifestyles. Our research will help to raise the profile of sharks and portray them as animals with advanced sensory systems and complex visual behaviours rather than just dangerous killing machines. Studying the vision of sharks may also help to reduce the number (currently >50,000) that are killed each year as bycatch by Australian long-line fisheries and make a valuable contribution to one of Australia's National Research Priorities (an Environmentally Sustainable Australia) for managing and conserving our biodiversity.Read moreRead less
Early life-history sex determination in reef fishes. In many fishes, gender is influenced by environmental conditions experienced after hatching. However, the timing, cues, and developmental pathways of sex determination are poorly understood. This research will establish how environmental conditions during the juvenile phase control patterns of sex determination in reef fishes and determine if sex differentiation is a response to local- or broad-scale environmental cues.

However, the timing, cues, and developmental pathways of sex determination are poorly understood. This research will establish how environmental conditions during the juvenile phase control patterns of sex determination in reef fishes and determine if sex differentiation is a response to local- or broad-scale environmental cues. An individual's gender has profound and significant consequences for all aspects of its biology and the mechanism of sex determination has important implications for population ecology. This project will test theory in evolutionary ecology and greatly benefit the management of reef fisheries.Read moreRead less
