The roles of stress and immunocompetence in biological invasions. Invasive species pose a major threat to biodiversity worldwide; and within Australia, cane toads are widely viewed as one of the biggest such problems. Building on recent studies that reveal weakened immune systems in invasion-front toads, this project will provide a comprehensive understanding of immune responses in cane toads and native frogs, with the aim of exploiting the toads' immunocompromised state to develop new and more ....The roles of stress and immunocompetence in biological invasions. Invasive species pose a major threat to biodiversity worldwide; and within Australia, cane toads are widely viewed as one of the biggest such problems. Building on recent studies that reveal weakened immune systems in invasion-front toads, this project will provide a comprehensive understanding of immune responses in cane toads and native frogs, with the aim of exploiting the toads' immunocompromised state to develop new and more effective control measures. The project will develop a new paradigm about the roles of stress and immunity in biological invasion, applicable to the control of other invasive species and to understanding processes at work when environmental changes force species to shift their ranges.Read moreRead less

Extreme Heat: A new driver of desert mammal assemblages . Heat waves cause more deaths than any other severe weather event and are becoming longer, more frequent and more intense. Consequently, extreme heat may soon rival predation and rainfall as a major driver of desert mammal assemblages. This project will investigate how heat wave attributes (duration, intensity, frequency), species attributes (physiology, behaviour, plasticity) and landscape features (refuges, fire, grazing) interact and co ....Extreme Heat: A new driver of desert mammal assemblages . Heat waves cause more deaths than any other severe weather event and are becoming longer, more frequent and more intense. Consequently, extreme heat may soon rival predation and rainfall as a major driver of desert mammal assemblages. This project will investigate how heat wave attributes (duration, intensity, frequency), species attributes (physiology, behaviour, plasticity) and landscape features (refuges, fire, grazing) interact and contribute to lethal and sublethal effects of extreme heat on desert mammals. Modelling will predict changes in desert mammal assemblages under different climatic and land management scenarios. Results will inform fire and grazing management, threatened species recovery programs and arid zone restoration. Read moreRead less
Sediment and seed bank dynamics in river systems of southeastern Australia: Implications for vegetation-based river rehabilitation. Every year in Australia millions of dollars are spent revegetating degraded riparian corridors as part of best practice river rehabilitation. The planting and maintenance of riparian tubestock is an expensive but essential component of current on-the-ground river management across the country. What if the success rate of riparian rehabilitation could be enhanced by ....Sediment and seed bank dynamics in river systems of southeastern Australia: Implications for vegetation-based river rehabilitation. Every year in Australia millions of dollars are spent revegetating degraded riparian corridors as part of best practice river rehabilitation. The planting and maintenance of riparian tubestock is an expensive but essential component of current on-the-ground river management across the country. What if the success rate of riparian rehabilitation could be enhanced by combining geomorphic and ecological knowledge to maximise the germination of native seeds stored in riparian seed banks? As the conservation of biodiversity becomes integral to environmental management, understanding riparian seed bank dynamics and seedling establishment within a geomorphic framework is an essential tool in river rehabilitation practice.Read moreRead less

There is a rapidly increasing demand for a range of environmental data. For example, information on soil moisture status is required for efficient and sustainable water use. Moreover, irrigation practices and large scale clearing have led to serious land degradation through increased salinity from rising water tables. Combined soil moisture and salinity measurement will provide important insight to this complex issue. Further, understanding the complex and rich biodiversity of Australian flora and its adaptation to droughts and fire is essential to ensuring Australian ecosystem longevity. Knowledge of flora changes through time as a function of soil moisture content and salinity is key to gaining this understanding.Read moreRead less

Invasion of plant communities by exotic plants is a significant threat to biodiversity and ecosystem processes globally. This proposal seeks to understand strategies of invasive plants in novel environments both now and under predicted future conditions, using the framework of leaf carbon strategies. Comparative and experimental approaches will be used to understand leaf trait relationships of invasive compared with native species. This will contribute substantially to our understanding of global plant functional relationships, thereby enabling better prediction of potential invaders. The resulting data will also provide critical input for models of plant, ecosystem and biosphere responses to global change incorporating invasion dynamics.Read moreRead less
