Do microbes facilitate the invasion of marine plants? Worldwide, management of invasive species is limited by the understandings of processes that allow invasive species to establish and proliferate in a new environment. It is believed that marine microbes play a critical, but untested, role in the establishment of invasive marine macrophytes. This project aims to test the theory by integrating cutting edge microbial ecology with eukaryote ecology, two largely disparate research areas. Invasive ....Do microbes facilitate the invasion of marine plants? Worldwide, management of invasive species is limited by the understandings of processes that allow invasive species to establish and proliferate in a new environment. It is believed that marine microbes play a critical, but untested, role in the establishment of invasive marine macrophytes. This project aims to test the theory by integrating cutting edge microbial ecology with eukaryote ecology, two largely disparate research areas. Invasive species are a serious threat to biodiversity globally and cost more than $4 billion annually. This project aims to create new knowledge essential for safeguarding Australia’s marine ecosystems from invasive pests, and will place Australia at the forefront of invasion ecology.Read moreRead less
Manipulating population sex ratio to eradicate invasive mouse populations. This project aims to use house mice, an Australian pest of economic importance which is also a highly tractable system for testing evolutionary theory and generating practical outcomes. Manipulating population sex ratio is a powerful tool for either enhancing the viability of threatened species or decimating pests. However, despite much scientific effort testing sex ratio theory, the cryptic mechanisms driving sex allocat ....Manipulating population sex ratio to eradicate invasive mouse populations. This project aims to use house mice, an Australian pest of economic importance which is also a highly tractable system for testing evolutionary theory and generating practical outcomes. Manipulating population sex ratio is a powerful tool for either enhancing the viability of threatened species or decimating pests. However, despite much scientific effort testing sex ratio theory, the cryptic mechanisms driving sex allocation remain unidentified, hindering progress in these fields. The project will identify the mechanisms by which sex ratio adjustments are made and establish how individual-level responses influence insular population structure and growth. It will provide benefits by assisting Australia's efforts in eradicating invasive mouse populations.Read moreRead less
Determining how plant populations will respond to climate change. It is widely predicted that global climate change will result in extinctions, invasions and disruption of the ecosystem services plants provide. In order to manage or adapt to these consequences of changing climate we need accurate forecasts of where suitable conditions for sustainable plant populations will occur. This project will enable better forecasts of where and how fast plant populations will expand or contract in response ....Determining how plant populations will respond to climate change. It is widely predicted that global climate change will result in extinctions, invasions and disruption of the ecosystem services plants provide. In order to manage or adapt to these consequences of changing climate we need accurate forecasts of where suitable conditions for sustainable plant populations will occur. This project will enable better forecasts of where and how fast plant populations will expand or contract in response to climate change. New population modelling methods which integrate plant survival, growth and reproduction along environmental gradients, together with field studies at unprecedented national and international scales, will enable better forecasts of future locations for plant dependent industries and environmental services.Read moreRead less
From individuals to mass organisation: aggregation, synchronisation and collective movement in locusts. By combining field biology, robotics and mathematics, this project will determine how animals flock or swarm and, in particular, how locust nymphs control their collective movement over their lifetime. The mathematical models derived during the project will be directly applied to controlling outbreaks of locusts in Australia, South and North Africa.
