Applying search theory for eradicating invasive species. Invasive species have major economic and environmental impacts in Australia and are a major cause of extinctions worldwide. Monitoring is crucial for the timely control of invasive species in sensitive environments. Early detection increases the probability of eradication and increased accuracy in detection reduces the impact of control programs on non-target species. Efficient monitoring also is crucial in determining whether eradication ....Applying search theory for eradicating invasive species. Invasive species have major economic and environmental impacts in Australia and are a major cause of extinctions worldwide. Monitoring is crucial for the timely control of invasive species in sensitive environments. Early detection increases the probability of eradication and increased accuracy in detection reduces the impact of control programs on non-target species. Efficient monitoring also is crucial in determining whether eradication has succeeded. Search Theory has been applied for over 60 years in a wide range of non-biological monitoring problems, resulting in large increases in target detection rates. Gains of a similar magnitude in invasive species detection would greatly enhance Australia's capacity to manage these threats.Read moreRead less
Mechanisms of sound absorption at the nanoscale. Understanding the interaction of sound with nanoscale structures will guide the creation of novel carbon nanotube materials, optimised for sound absorption, which have potential application anywhere that noise exists and needs to be attenuated. Fuel savings from reduced drag and weight in applications such as jet aircraft engines are also expected.
The evolution of egg retention and sex allocation: a phylogenetic contrasts study using facultatively ovoviviparous thrips. Australian idolothripine thrips provide an unparalleled opportunity for investigating the evolution of reproduction. They constitute the only group to contain many species in which the females choose among live birth, egg laying or both. They also choose the sex of each offspring. We will use phylogenetics and experimentation to understand the evolutionary pressures that le ....The evolution of egg retention and sex allocation: a phylogenetic contrasts study using facultatively ovoviviparous thrips. Australian idolothripine thrips provide an unparalleled opportunity for investigating the evolution of reproduction. They constitute the only group to contain many species in which the females choose among live birth, egg laying or both. They also choose the sex of each offspring. We will use phylogenetics and experimentation to understand the evolutionary pressures that led to and maintain live birth and the allocation of sex. This will produce new insights into fundamental questions about the evolution of animal reproduction. Our collaborative approach will make Australian thrips and research an international cornerstone in the biology of reproductive evolution.Read moreRead less
What drives parasite spread through social networks: lessons from lizards. Australia's biodiversity is continually threatened by new epidemics of local and foreign diseases and parasites. This project will enhance our understanding of how these diseases spread, allowing more effective controls to be developed to protect wildlife species, animal populations and, ultimately, Australian ecosystems.
Parasite transmission through social networks in the pygmy bluetongue lizard. Australia's biodiversity is continually threatened by new epidemics of diseases and parasites, some local, others from overseas. This project will provide information on how they spread so that more effective management of these diseases can be developed to protect wildlife species, animal populations and, ultimately, Australian ecosystems.
