Population response to climate change in a host-parasite system. A computer model will be developed to predict the impact of climate change on geographic ranges and population densities of the sleepy lizard, the world's only lizard to be recorded to show long-term monogamy, and its associated parasitic ticks. A blood parasite, carried by the tick, and potentially harmful to the lizards, will also be included in the investigation. The study forms the next step in a 21 year research project by Fli ....Population response to climate change in a host-parasite system.

A blood parasite, carried by the tick, and potentially harmful to the lizards, will also be included in the investigation. The study forms the next step in a 21 year research project by Flinders university biologists. It will inform wildlife management about disease control and provide deeper understanding of the response of Australian fauna to climate change.Read moreRead less
Dispersal and gene flow in habitat-forming algae. The temperate coast of Australia has a unique and diverse algal flora. Many of these algae play a central role in subtidal ecology by providing habitat to an astonishing diversity of taxa. Despite this, we have no understanding of levels of gene flow within and among populations of habitat forming algae or how such populations persist in nature. By addressing this lack of knowledge, my research will contribute information that is critical for the ....Dispersal and gene flow in habitat-forming algae. The temperate coast of Australia has a unique and diverse algal flora. Many of these algae play a central role in subtidal ecology by providing habitat to an astonishing diversity of taxa. Despite this, we have no understanding of levels of gene flow within and among populations of habitat forming algae or how such populations persist in nature. By addressing this lack of knowledge, my research will contribute information that is critical for the conservation and management of algal habitats. This is particularly pertinent because anthropogentic stressors are beginning to precipitate significant changes in algal forests along Australia's coastline. Read moreRead less
Diatom frustules: nanostructures at the base of ocean food webs. Molecules interacting with surfaces are fundamental to biological, chemical and physical processes, including desalinization membrane design, lab-on-a-chip systems, industrial catalysis, bioremediation, neurophysiology and uptake of nutrients for incorporation into food webs. Here, we use diatoms as models for molecule-surface interactions to find basic principles that underlay all of these interactions.

LIZARD SOCIAL BEHAVIOUR AND THE INFLUENCE OF PARASITES. We ask why stable social group living in animals, with well documented benefits, is relatively rare. One cost is the enhanced opportunity for parasite and disease transmission among group members. We will explore, for a lizard, the impact of group living on parasite infections, and the costs of infection. We expect to produce observational and experimental results with an unusual level of detail, and with a fresh taxonomic perspective to in ....LIZARD SOCIAL BEHAVIOUR AND THE INFLUENCE OF PARASITES. We ask why stable social group living in animals, with well documented benefits, is relatively rare. One cost is the enhanced opportunity for parasite and disease transmission among group members. We will explore, for a lizard, the impact of group living on parasite infections, and the costs of infection. We expect to produce observational and experimental results with an unusual level of detail, and with a fresh taxonomic perspective to influence debate in this central area of behavioural ecology. We will also produce new information on behavioural ecology of Australian fauna, important for conservation management and ecotourism.Read moreRead less
Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that clim ....Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that climate change was to blame. This study will refine our knowledge of the timing and causes of these extinctions in southern Australia by assessing how communities responded to climate change in the lead-up to human arrival. It will provide vital information for managing the conservation of many modern species and guide us in limiting future losses.Read moreRead less

The extent of competition between the native and introduced herbivores of Kangaroo Island. This project examines grazing behaviour and competition among native and introduced herbivores to optimise limited resources in an ecologically fragile environment. The project will provide a biological basis for the development of management strategies to provide positive outcomes for the Kangaroo Island environment and potential economic benefit to the local and national economy. Environmental benefit in ....The extent of competition between the native and introduced herbivores of Kangaroo Island. This project examines grazing behaviour and competition among native and introduced herbivores to optimise limited resources in an ecologically fragile environment. The project will provide a biological basis for the development of management strategies to provide positive outcomes for the Kangaroo Island environment and potential economic benefit to the local and national economy. Environmental benefit includes the reduction of total grazing pressure on pastures and native vegetation of Kangaroo Island, which is one of Australia’s top 15 biodiversity ‘hot spots’, and thus help with conservation efforts on Kangaroo Island. Economic benefit will follow if farmers receive income from a currently wasted resource.Read moreRead less

Bottom-up effects of nutrients on estuarine fish related ecosystems. Over 84% of Australians live within 50 km of the coast, and have large impacts on coastal ecosystems, such as increasing nutrients in estuaries. Nutrients have strong bottom-up effects on fish ecosystems, especially during critical juvenile life history stages. Elevated nutrients can alter fish productivity and sustainability, having ecosystem and social implications. This project will combine experimental evidence with novel a ....Bottom-up effects of nutrients on estuarine fish related ecosystems. Over 84% of Australians live within 50 km of the coast, and have large impacts on coastal ecosystems, such as increasing nutrients in estuaries. Nutrients have strong bottom-up effects on fish ecosystems, especially during critical juvenile life history stages. Elevated nutrients can alter fish productivity and sustainability, having ecosystem and social implications. This project will combine experimental evidence with novel approaches of fatty acid tracers in food-webs and fish otolith (earbone) chemistry, to determine how nutrients affect fish ecosystems, recruitment, and survivorship. This project will provide information needed to create sustainable fisheries, to safeguard Australia's fisheries resources for future generations.Read moreRead less
