Effects of invasive macrofauna on marine biodiversity and ecosystem function. The project will identify environmental and biological factors that help prevent invasion of native marine communities by introduced pests, and describe thresholds in marine systems where further loss of macrofaunal species results in declines in ecosystem health.

Summary
Ecology of novel coral reef ecosystems. Coral reef ecosystems are changing. Some of these changes are predictable, based on how species respond to climate change. This project will utilise information on species vulnerability to predict what reef ecosystems, including corals, fishes and invertebrates, will look like in the future and how this will affect the benefits we gain from reefs.
Long-term changes in the phenology of Australia's temperate marine macroalgae: has climate change impacted the world's most diverse algal flora? Looking back at herbarium specimens collected over the past 100 years, this project will reconstruct a historical baseline of reproduction in Australian seaweeds. This unique opportunity to rigorously assess the extent of recent changes in response to ocean warming, will help secure the continued existence of the most species rich marine flora in the wo ....Long-term changes in the phenology of Australia's temperate marine macroalgae: has climate change impacted the world's most diverse algal flora?

Ecological competition between corals and algae in a high carbon dioxide world: understanding the mechanisms and implications for reef ecosystems. This project will explore the impacts of ocean acidification on ecological interactions between two key groups on reefs: corals and seaweeds. Such knowledge is fundamental to managing the consequences of increased global carbon emissions on the ecology and persistence of Australian marine ecosystems, including the Great Barrier Reef.

Science-based management of coral reefs provides enormous environmental, social and economic benefit to Australia and other tropical maritime nations. The proposed research will provide scientific knowledge and research training that underpins the management and long-term sustainability of Australian reef resources. Climate change research is vital for supporting the sustainable use of the ecosystem goods and services provided by reef ecosystems (e.g. to tourism and fishing industries, recreational users and indigenous Australians). This research will place Australia in the forefront of understanding and responding to the regional-scale impacts of climate change on tropical societies and economies.Read moreRead less

Summary
A new functional approach to coral reefs. 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 in ....A new functional approach to coral reefs. 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 relationship between connectivity and resilience, however, remains poorly substantiated by empirical data. By manipulating connectivity in laboratory experime ....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 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
Intervention ecology on coral reefs: a new role for fishes. In a world where few intact reefs remain, the goal of this project is to find ways to restore degraded reefs. Recent research has identified the species responsible for removing harmful algae from coral reefs, while advances in mariculture provide us with the capacity to rear these critically important reef fish species. Combining captive rearing, experimental manipulations, and a global analysis of the functional capacity of herbivorou ....Intervention ecology on coral reefs: a new role for fishes. In a world where few intact reefs remain, the goal of this project is to find ways to restore degraded reefs. Recent research has identified the species responsible for removing harmful algae from coral reefs, while advances in mariculture provide us with the capacity to rear these critically important reef fish species. Combining captive rearing, experimental manipulations, and a global analysis of the functional capacity of herbivorous fishes, in intact, degraded and human-modified systems, the research will explore the potential for restoring, or boosting, the capacity of reefs to withstand disturbance. The goal is to provide the scientific knowledge required to directly modify the key processes operating on coral reefs. 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 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

This project aims to determine if trait plasticity mediates functional degradation of coral reefs. It will use natural environmental gradients to identify mechanisms that enable corals to persist in marginal habitats. The project will use three-dimensional imaging to measure how variability in traits influences functional redundancy. This will facilitate better predictions of the effects of environmental change on reef systems. Expected outcomes include improved understanding of the response of coral reef ecosystems to environmental change and a framework for predicting reefs at risk of degradation. Benefits will be to both global biodiversity conservation and the provision of ecosystem services in reef dependent communities.Read moreRead less
