Summary
Sedentary behaviours and physical inactivity play a major role in the rising prevalence of obesity among children in Australia. This intervention study will take place in the school and family settings which play a critical role in shaping children's health behaviours. The objective is to determine whether a 2-year behavioural intervention reduces sedentary behaviour and promotes physical activity and results in improved health among 8-9 year old children.
Globalisation, Sustaining Rural Livelihoods and Organics: The Impacts of the Transformation in the Production and Consumption of Organic Foods. The production and consumption of organic foodstuffs has been transformed in recent years, from a focus on small-scale production for local consumption to a global industry dominated by large agribusiness companies and supermarkets.

The production and consumption of organic foodstuffs has been transformed in recent years, from a focus on small-scale production for local consumption to a global industry dominated by large agribusiness companies and supermarkets. This not only raises questions about the role of organic agriculture in achieving sustainable development in Australia and elsewhere, but is also creating relationships of dependency within the less developed world which may well reduce food security and make the problem of feeding growing populations more difficult. This study seeks to develop a range of policy alternatives in order to enhance sustainability through organic farming.Read moreRead less
Habitat degradation on coral reefs. This project aims to determine how reef degradation modifies predator-prey dynamics in fish communities, and how parental effects may help species to cope with habitat change. Live corals are ecosystem engineers that support the world’s most biodiverse communities, but anthropogenic factors have led to unprecedented global declines in live coral. The transition from live to dead coral-dominated habitats is associated with a modified sensory landscape of fear f ....Habitat degradation on coral reefs. This project aims to determine how reef degradation modifies predator-prey dynamics in fish communities, and how parental effects may help species to cope with habitat change. Live corals are ecosystem engineers that support the world’s most biodiverse communities, but anthropogenic factors have led to unprecedented global declines in live coral. The transition from live to dead coral-dominated habitats is associated with a modified sensory landscape of fear for resident fishes, via chemical interference emanating from degraded coral. Inter-generational advantages would help management to regulate reef usage to promote resilience.Read moreRead less
Sitting Less And Moving More: Population Health Research To Understand And Influence Sedentary Behaviour

Summary
The majority of Australian adults spend most of their waking hours sitting: at home, at work, and in their cars; most do not participate in exercise or sport. This leads to weight gain and to diseases of inactivity (particularly diabetes, heart disease, cancer and depression). New research will measure sitting time and the physical activity in people's daily lives, what factors encourage inactivity, and how to increase activity levels, especially among the ageing 'baby boomer' population.
An integrated examination of the drivers of movements of large filter feeding organisms of high ecotourism value: a case study. This aim is to define key drivers behind movements of large filter-feeding organisms, using the manta ray as a model system. As dive eco-tourism often depends on the presence of such charismatic filter-feeding animals, an understanding of why animals occupy particular sites at particular times is important, especially in the face of climate change.

Summary
The effects of sea-level rise on the feeding ecology of coral-reef fishes in shallow water, and the implications for reef-flat food webs. Coral reefs are threatened by climate change, but the effects of sea-level rise on wide, shallow reef flats are rarely investigated. This project will examine how the ecology of fish on reef flats varies with tidal state, how these changes alter food webs over tidal cycles, and the implications of sea-level rise leading to a 'permanent high tide'.
The nature of self-recognition: novel approaches to vexing questions. Mirror self-recognition has often been interpreted as evidence for the presence of some form of self-concept/awareness. Children from age 2 onwards investigate their own bodies after seeing a novel mark on their heads in the mirror (surreptitiously placed in their hair by the experimenter). Younger children and most animals do not respond to their images in such a way (instead, for example, treating it as another individual). ....The nature of self-recognition: novel approaches to vexing questions. Mirror self-recognition has often been interpreted as evidence for the presence of some form of self-concept/awareness. Children from age 2 onwards investigate their own bodies after seeing a novel mark on their heads in the mirror (surreptitiously placed in their hair by the experimenter). Younger children and most animals do not respond to their images in such a way (instead, for example, treating it as another individual). The present experiments probe the nature of self-recognition using novel digital video technology rather than mirrors. This technology allows us to manipulate the contingency and appearance of the image. Five studies investigate the performance of 2 to 4-year-old children, autistic children, chimpanzees and dolphins to determine whether they recognize themselves and what underwrites their performance on the tasks. The innovative use of modern technology is expected to answer some of the most persistent questions in psychology.

Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interac ....Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interactions, whilst models do not represent the functional characteristics and adaptions of eucalypts. This project will develop a strong evidence- and process-based understanding to quantify the functional behaviour of drought-adapted Eucalyptus species and leverage this insight to make future model projections.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.

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

Fish play an important role in many Australian's lives, they are a source of recreation for scuba divers, snorkelers and fishermen, they are a draw card for tourists as well as a healthy source of food. This project will investigate the visual world of fish, unravelling their use of colour communication, thereby identifying environmental factors affecting successful communication. Such a study will provide insight into the impact on reef fish of changes in water quality (e.g. river runoff) and temperature (e.g. bleaching events), as well as factors that affect the successful rearing of fish in aquaculture.
