Coral reef connectivity: an empirical and theoretical synthesis. Australia possesses the greatest marine biodiversity of any first world country and this biodiversity is a major contributor to our economic wealth. Nonetheless, Australia's coral reef communities are threatened by various human activities and climate change. Wisely designed systems of marine reserves are critical to mitigating threats to coral reefs, but existing approaches do not incorporate crucial information about ecological c ....Coral reef connectivity: an empirical and theoretical synthesis. Australia possesses the greatest marine biodiversity of any first world country and this biodiversity is a major contributor to our economic wealth. Nonetheless, Australia's coral reef communities are threatened by various human activities and climate change. Wisely designed systems of marine reserves are critical to mitigating threats to coral reefs, but existing approaches do not incorporate crucial information about ecological connections between reefs. We will use graph theory metrics to identify priority reefs for protection based on empirical genetic and hydrological connectivity information. In addition, we will determine the sensitivity of these priorities to climate change scenarios.Read moreRead less
General theory for eradicating multiple invasive species from threatened island ecosystems. Invasive species threaten many of Australia's unique flora and fauna. Our island ecosystems have evolved in the absence of mammalian predators, and are therefore particularly vulnerable. When both cats and rats invade an island, they can quickly decimate the populations of native species, particularly seabirds, and threaten them with extinction. Unfortunately, poorly planned eradication of these invasive ....General theory for eradicating multiple invasive species from threatened island ecosystems. Invasive species threaten many of Australia's unique flora and fauna. Our island ecosystems have evolved in the absence of mammalian predators, and are therefore particularly vulnerable. When both cats and rats invade an island, they can quickly decimate the populations of native species, particularly seabirds, and threaten them with extinction. Unfortunately, poorly planned eradication of these invasive species can destabilise the complex island ecosystems, further endangering the native species. The results of this project will help conservation managers to plan eradication strategies that cost-effectively eradicate populations of two introduced species, without threatening native wildlife.Read moreRead less
How do characteristics of seeds and landscape heterogeneity determine plant spread in new environments? Climate change and exotic invasions are among the greatest threats to Australia's, and the world's, biodiversity. Under a rapidly changing climate many Australian plant species will have to spread across a fragmented landscape to persist. In order to contain or eradicate invasive plant species we need to know how they will spread in novel landscapes. We will develop models which will be used f ....How do characteristics of seeds and landscape heterogeneity determine plant spread in new environments? Climate change and exotic invasions are among the greatest threats to Australia's, and the world's, biodiversity. Under a rapidly changing climate many Australian plant species will have to spread across a fragmented landscape to persist. In order to contain or eradicate invasive plant species we need to know how they will spread in novel landscapes. We will develop models which will be used for invasive plants to predict ecological and evolutionary responses to novel landscapes and novel dispersers and for native plants to predict their spread in to fragmented landscapes. These models can be used to prioritise management actions for species of most conservation concern, and predict how far and fast invasive species will spread.Read moreRead less
Optimal environmental monitoring under severe uncertainty. Environmental monitoring is a type of quality control that informs managers about the health of the environment and about how well their management systems are performing. Because it is a critical, but expensive, component of sustainable management, it is important to ensure value for resources spent on monitoring and that environmental impacts will be detected if they are occurring. We argue that current approaches to environmental mana ....Optimal environmental monitoring under severe uncertainty. Environmental monitoring is a type of quality control that informs managers about the health of the environment and about how well their management systems are performing. Because it is a critical, but expensive, component of sustainable management, it is important to ensure value for resources spent on monitoring and that environmental impacts will be detected if they are occurring. We argue that current approaches to environmental management ensure neither efficiency nor environmental security. The aim of the project is to develop theories and techniques to make monitoring both cost effective and reliable, thereby providing monetary savings and better environmental outcomes.Read moreRead less
The role of learning in conservation management: developing adaptive approaches for the conservation of biodiversity in a changing climate. Biodiversity underpins several major industries: agriculture, tourism, forestry and fisheries. To mitigate the loss of biodiversity, there have been significant investments from all levels of government, including 2.2 billion dollars to manage biodiversity and 138 million dollars simply to gather data on the impact of climatic changes. Despite this well inte ....The role of learning in conservation management: developing adaptive approaches for the conservation of biodiversity in a changing climate. Biodiversity underpins several major industries: agriculture, tourism, forestry and fisheries. To mitigate the loss of biodiversity, there have been significant investments from all levels of government, including 2.2 billion dollars to manage biodiversity and 138 million dollars simply to gather data on the impact of climatic changes. Despite this well intended funding, the key questions of how to best allocate this money between the many threatened species and regions of Australia, and how to adapt this allocation in light of climatic changes, remain unanswered. Our research will develop explicit and practical frameworks by which we can cost efficiently learn and act simultaneously.Read moreRead less
Do dingoes regulate the structure of arid ecosystems? Predation by the red fox and land degradation due to overgrazing have been identified as major factors contributing to the loss of biodiversity in arid Australia. I hypothesise that dingoes by regulating populations of foxes and herbivores may have positive effects on biodiversity. If this hypothesis is supported, this project will have great significance for biodiversity conservation and is likely to irrevocably change land and wildlife man ....Do dingoes regulate the structure of arid ecosystems? Predation by the red fox and land degradation due to overgrazing have been identified as major factors contributing to the loss of biodiversity in arid Australia. I hypothesise that dingoes by regulating populations of foxes and herbivores may have positive effects on biodiversity. If this hypothesis is supported, this project will have great significance for biodiversity conservation and is likely to irrevocably change land and wildlife management practices in Australia. The recommendations arising from this research will influence policy on land management and contribute to achieving an environmentally sustainable Australia.
