The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure.

This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interactions and an ability to quantify the biomass, social structure, and behaviours of predators required to influence these processes. Benefits should include improvements in how the ecological role of large carnivores is measured, and when and where carnivore populations should be culled or conserved.Read moreRead less
Rehabilitating a changing landscape: using the latest advances in koala ecology to direct adaptive management. The koala has been identified as one of the world's flagship species suffering from environmental change. In contrast to the decline of koalas in New South Wales generally, the eucalypts planted in Gunnedah to combat salinity led to an increase in koalas. However, the startlingly high death rate of Gunnedah koalas (25 per cent of the population) in the heatwave during the drought in 200 ....Rehabilitating a changing landscape: using the latest advances in koala ecology to direct adaptive management. The koala has been identified as one of the world's flagship species suffering from environmental change. In contrast to the decline of koalas in New South Wales generally, the eucalypts planted in Gunnedah to combat salinity led to an increase in koalas. However, the startlingly high death rate of Gunnedah koalas (25 per cent of the population) in the heatwave during the drought in 2009 must be understood. There are also new threats brought about by intensive land modification. This project aims to determine the effects of environmental change on the koala population through a study of landscape ecology, leaf chemistry, disease epidemiology and koala movements. This aims to lead to better management decisions for arboreal fauna.Read moreRead less
The contribution of human/marine herbivore interactions to reef degradation. This project aims to define how interactions between human society and herbivores influence marine ecosystem structure and function. It will analyse geographic patterns from recent systematic sampling of reef communities worldwide and study fish, macro-invertebrate and meso-grazer herbivory to identify herbivores’ role in the collapse and recovery of reef ecosystems. This project will examine the match between a critica ....The contribution of human/marine herbivore interactions to reef degradation. This project aims to define how interactions between human society and herbivores influence marine ecosystem structure and function. It will analyse geographic patterns from recent systematic sampling of reef communities worldwide and study fish, macro-invertebrate and meso-grazer herbivory to identify herbivores’ role in the collapse and recovery of reef ecosystems. This project will examine the match between a critical ecosystem function and community structure across local to global scales, including the identification of non-linearities and interactions involving human effects on this process. This research is expected to safeguard marine ecosystems from collapse.Read moreRead less
From prediction to adaptation: responding to rapid ecosystem shifts under climate change. Nobody knows exactly how climate change will affect the ecosystems on which we depend for our own existence, though negative impacts are widely predicted. This project integrates mathematical, economic and ecological approaches to learn about the most effective way to spend limited funds for sustaining ecosystems threatened by climate change.
Landscape-scale monitoring and adaptive management of woodland birds in the Mt Lofty Ranges. Despite the fundamental role of scientific monitoring in nature conservation, its research importance and potential is widely neglected. There is an urgent need to improve quantitative rigour, particularly to ensure adequate statistical power is achieved when monitoring at a landscape scale. We will apply new analytical tools to the problem of devising a powerful and flexible monitoring regime for a high ....Landscape-scale monitoring and adaptive management of woodland birds in the Mt Lofty Ranges. Despite the fundamental role of scientific monitoring in nature conservation, its research importance and potential is widely neglected. There is an urgent need to improve quantitative rigour, particularly to ensure adequate statistical power is achieved when monitoring at a landscape scale. We will apply new analytical tools to the problem of devising a powerful and flexible monitoring regime for a highly threatened woodland bird community in South Australia. Monitoring will be embedded within a decision-making framework with explicit links to local management agencies. Results will be broadly applicable across agricultural areas of Australia, where bird assemblages are in general decline.Read moreRead less
Landscape level effects on dispersal behaviour and gene flow in the logrunner, a rainforest restricted bird. Dispersal is thought to be critical for the persistence of small avian populations in fragmented landscapes. However, our knowledge of dispersal is limited. I will combine behavioural observations on radiotagged birds and powerful genetic markers to examine the effects of habitat fragmentation on the dispersal behaviour of a rainforest restricted bird, the logrunner. This study will deter ....Landscape level effects on dispersal behaviour and gene flow in the logrunner, a rainforest restricted bird. Dispersal is thought to be critical for the persistence of small avian populations in fragmented landscapes. However, our knowledge of dispersal is limited. I will combine behavioural observations on radiotagged birds and powerful genetic markers to examine the effects of habitat fragmentation on the dispersal behaviour of a rainforest restricted bird, the logrunner. This study will determine how landscape structure influences the movement of juvenile logrunners, investigate the causes and consequences of variation in juvenile dispersal behaviour, and use molecular data to determine how connectivity between habitats effects the genetic structure of logrunner populations.Read moreRead less
The conservation of widely distributed species: implications of differences between western and eastern koala populations. Koalas are an iconic species in Australia, generating $2.5 billion in tourist income alone. This project will be a first to test cross-regional variations in koala-habitat relationships, with implications for conservation of other species occupying broad geographical ranges. It will also predict the effect of future climate change on western koala populations living at the ....The conservation of widely distributed species: implications of differences between western and eastern koala populations. Koalas are an iconic species in Australia, generating $2.5 billion in tourist income alone. This project will be a first to test cross-regional variations in koala-habitat relationships, with implications for conservation of other species occupying broad geographical ranges. It will also predict the effect of future climate change on western koala populations living at the margin of their ecological tolerances. It will provide regional natural resource management bodies and state conservation agencies with a sound ecological framework to conserve western koalas in the long term. Regional communities will benefit from involvement by incorporating new conservation knowledge into sub-catchment and property management planning.Read moreRead less
A Bayesian framework for metapopulation dynamics of species in endangered communities: integrating demographic, environmental and genetic data. Biodiversity conservation is a spatial and temporal problem. Populations change in time, constrained by the structure and spatial division of their habitat.

Biodiversity conservation is a spatial and temporal problem. Populations change in time, constrained by the structure and spatial division of their habitat. This study will develop a tool that can be used to assess the influence of environmental fluctuations and landscape heterogeneity on the persistence of endemic species in the mound springs of the Great Artesian Basin. Using a Bayesian framework to integrate data from diverse sources, we will develop models for the biodiversity impacts of groundwater withdrawal and climate change in central Australia. These tools are essential for management of this ecosystem, which has been listed as an 'endangered community' under the Environmental Protection and Biodiversity Conservation Act of 1999.Read moreRead less

This project aims to identify the key ecosystem functions that are needed to sustain coral reefs and determine their susceptibility to disturbance. Around the world coral reefs are changing fast, challenging traditional scientific, management, and governance approaches. This project plans to address this challenge by implementing a new, functional, approach exploiting a unique combination of evolutionary and ecological methodologies. Expected outcomes include a global overview of ecosystem function and an in-depth understanding of how ecosystems change over time. This is likely to result in specific, and practical, management objectives by identifying crucial ecosystem functions that support reefs and the people who rely on them. Read moreRead less
Promoting resilience of ecosystems through connectivity. The resilience of ecosystems in the face of major environmental disturbances is emerging as a major concern for modern ecology. Connectivity of ecosystem components is a critically important element of ecosystem function and should, theoretically, be central to system resilience.

The resilience of ecosystems in the face of major environmental disturbances is emerging as a major concern for modern ecology. Connectivity of ecosystem components is a critically important element of ecosystem function and should, theoretically, be central to system resilience. The relationship between connectivity and resilience, however, remains poorly substantiated by empirical data. By manipulating connectivity in laboratory experiments using a well-understood model marine system, the project aims to determine how connectivity affects resilience. It could provide a crucial step towards integrating connectivity into management and conservation of natural resources.Read moreRead less
