Effect of deep-sea drilling on sustainability of deep-sea ecosystems. Offshore oil and gas production makes a significant contribution to the Australian economy and enhances our energy security. Australia's vast deep-sea reserves of hydrocarbons lie on the NW Shelf and in Bass Strait, ecological 'hot spots' that are extremely vulnerable to the impact of exploration, extraction and production. Using deep-sea equipment, we will conduct the field experiments that are essential to understanding the ....Effect of deep-sea drilling on sustainability of deep-sea ecosystems. Offshore oil and gas production makes a significant contribution to the Australian economy and enhances our energy security. Australia's vast deep-sea reserves of hydrocarbons lie on the NW Shelf and in Bass Strait, ecological 'hot spots' that are extremely vulnerable to the impact of exploration, extraction and production. Using deep-sea equipment, we will conduct the field experiments that are essential to understanding these ecosystems and the impact of deep-sea structures. Our advances will produce data and develop methodologies that will make Australia a world leader in reconciling our deep-sea energy and environmental needs.Read moreRead less
Understanding the crowd - improving accuracy in collective motion theory. This project intends to develop more accurate methods for predicting the motions of large groups. The amazing coordinated movements seen in large groups of animals are governed by simple interactions between individuals, termed rules of motion. In 2011, techniques were developed to estimate individual rules of motion from video tracking data. The project plans to build on these breakthroughs by using advanced tracking, mod ....Understanding the crowd - improving accuracy in collective motion theory. This project intends to develop more accurate methods for predicting the motions of large groups. The amazing coordinated movements seen in large groups of animals are governed by simple interactions between individuals, termed rules of motion. In 2011, techniques were developed to estimate individual rules of motion from video tracking data. The project plans to build on these breakthroughs by using advanced tracking, modelling and analysis to systematically determine the influence that different movement parameters have on rules of motion and how rules of motion are affected by group size. It aims to develop a framework for analysis and modelling built on the visual perception of individuals.Read moreRead less
Leadership matters: the emergence of informed leaders and their influence on group movement. This project will discover the effect of leadership and social structure on collective motion in schools of damselfish, swarms of honey bees and human pedestrians using videoed experiments and computer simulations. These findings will be important in preventing crowd stampedes, understanding risky road crossing behaviour and designing 'swarms' of robots.
Understanding biodiversity by experimental analysis of links between physical, chemical and biological properties of intertidal sediments. The coastal zone accounts for 38 % of total environmental services, estimated as $12 trillion per year. Over 90 % of current development and 80 % of Australians are found within 50 km of the coast, putting enormous pressure on these habitats. Intertidal/shallow subtidal sediments are the most extensive and productive (biologically and economically) coastal ....Understanding biodiversity by experimental analysis of links between physical, chemical and biological properties of intertidal sediments. The coastal zone accounts for 38 % of total environmental services, estimated as $12 trillion per year. Over 90 % of current development and 80 % of Australians are found within 50 km of the coast, putting enormous pressure on these habitats. Intertidal/shallow subtidal sediments are the most extensive and productive (biologically and economically) coastal habitats, supporting much of Australia's unique biodiversity. Their functioning depends on complex interactions among physical, chemical and biotic processes, yet is largely unknown. Understanding these processes is crucial for coastal planning and management, to minimise habitat-loss and retain biodiversity in these important habitats.Read moreRead less
Ecological patterns in deep-sea macro- and microbiotic communities on Vailulu'u Seamount and Ta'u Island, American Samoa. Volcanoes are viewed as large mountains that occasionally spurt smoke and debris into the air. But terrestrial volcanoes are but a small fraction of the volcanos on our planet, most simmer unobserved underneath the sea. The interdependence of biosphere, hydrosphere and lithosphere at volcanoes is amongst the most exciting and important research topics that help us understand ....Ecological patterns in deep-sea macro- and microbiotic communities on Vailulu'u Seamount and Ta'u Island, American Samoa. Volcanoes are viewed as large mountains that occasionally spurt smoke and debris into the air. But terrestrial volcanoes are but a small fraction of the volcanos on our planet, most simmer unobserved underneath the sea. The interdependence of biosphere, hydrosphere and lithosphere at volcanoes is amongst the most exciting and important research topics that help us understand how our planet has evolved and works through time. This project will used manned submersibles and remotely operated vehicles to conduct experiments at a submarine volcano that will help us understand how complex biological systems can form under such extreme conditions.Read moreRead less
The role of pulsed water events in structuring marine benthic communities along the southern Australian coastline. Marked differences in benthic community structure have been observed that are associated with pulsed cold-water events, possibly driven by internal wave phenomena. Such events have the potential to act as very important controls on both regional and local patterns of benthic biodiversity. To date, however, their effects and mechanisms of action have never been examined in Australi ....The role of pulsed water events in structuring marine benthic communities along the southern Australian coastline. Marked differences in benthic community structure have been observed that are associated with pulsed cold-water events, possibly driven by internal wave phenomena. Such events have the potential to act as very important controls on both regional and local patterns of benthic biodiversity. To date, however, their effects and mechanisms of action have never been examined in Australia. The fundamental outcome from this project will be the first assessment of the occurrence, geographical extent and ecological consequences of pulsed water phenomena along the southern Australian coastline.Read moreRead less
Multi-modal signals: an experimental analysis. This project is built upon innovations that permit the first exploration of an important, but previously-inaccessible, problem. We will continue to develop techniques with wide applicability for the analysis of movement, and will make them available to other research groups. The proposed work addresses a hot topic that is generating international attention; it will hence make a distinctive Australian contribution to a rapidly expanding research area ....Multi-modal signals: an experimental analysis.

We will continue to develop techniques with wide applicability for the analysis of movement, and will make them available to other research groups. The proposed work addresses a hot topic that is generating international attention; it will hence make a distinctive Australian contribution to a rapidly expanding research area. Results will be communicated through the WWW and science documentaries. Animal Behaviour is of great interest to the general public. This can be engaged to attract more young people to careers in science. We will continue to train postgraduates in a well-resourced and stimulating environment.Read moreRead less
From individual interactions to global patterns: understanding the basis of collective behaviour. Some of the most incredible sights in nature happen when animals form into groups, such as shoals or flocks. This study examines the phenomenon of collective animal behaviour to understand how simple interactions between group members scale to produce these behavioural spectacles.
Tracking moving targets: dynamic foraging in ants and slime moulds. This project will investigate how two self-organised systems, ants and slime moulds, deal with dynamic problems. Understanding how both organisms adapt to changes in their foraging environment will increase our knowledge of how self-organised systems function in both biological contexts and in human designed systems.
Deceptive signals in spiders. Animal communication involves a diversity of signals including visual displays, sounds and odours. Understanding the function of signals is difficult because humans cannot detect some signals such as UV light. This project investigates the functions of visual signals in two spider systems: the decorations in orb-webs and the colouration of crab spiders. We analyse whether these signals are cryptic or conspicuous. Do they attract prey or hide the spiders from predato ....Deceptive signals in spiders.

This project investigates the functions of visual signals in two spider systems: the decorations in orb-webs and the colouration of crab spiders. We analyse whether these signals are cryptic or conspicuous. Do they attract prey or hide the spiders from predators? Our project will make a significant contribution to understanding the evolution of these signals, and will, at least in part, help resolve century old debates surrounding their function.Read moreRead less
