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.

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
Linking phytoplankton to fisheries using zooplankton size spectra. This project aims to develop innovative numerical methods to understand the dynamics, carbon export, and trophic structure of zooplankton. The trophic links between phytoplankton, zooplankton and fisheries are unknown. The size- frequency distribution of zooplankton (size spectrum) is an innovative method for estimating their growth, predation and production as food for fish. Analysis of a global synthesis of zooplankton size dis ....Linking phytoplankton to fisheries using zooplankton size spectra. This project aims to develop innovative numerical methods to understand the dynamics, carbon export, and trophic structure of zooplankton. The trophic links between phytoplankton, zooplankton and fisheries are unknown. The size- frequency distribution of zooplankton (size spectrum) is an innovative method for estimating their growth, predation and production as food for fish. Analysis of a global synthesis of zooplankton size distributions from tropical to polar environments are expected to reveal these vital rates of pelagic ecosystems. The zooplankton rates will reveal, for the first time, the link between phytoplankton and fisheries, and will significantly improve ecosystem models and global assessments of environmental change.Read moreRead less
Predicting biodiversity distribution on the Antarctic continental shelf. This project aims to develop an international database of underwater observations to predict the distribution of seafloor biodiversity over the entire Antarctic continental shelf for the present day and to 2100. Antarctic seafloor communities are unique and highly diverse, but their distribution is poorly known because biological data are sparse. These predictions depend on a unique and validated approach to estimate the pr ....Predicting biodiversity distribution on the Antarctic continental shelf. This project aims to develop an international database of underwater observations to predict the distribution of seafloor biodiversity over the entire Antarctic continental shelf for the present day and to 2100. Antarctic seafloor communities are unique and highly diverse, but their distribution is poorly known because biological data are sparse. These predictions depend on a unique and validated approach to estimate the present and future redistribution of surface primary production to the seafloor, and will enable calculating the amount of atmospheric carbon captured and stored at the seafloor. The maps will be at an unprecedented resolution of around 2 kilometres, and be invaluable tools underpinning policy, management and future science.Read moreRead less
Marine urban development: how can ecology inform the design of multifunctional artificial structures?

This project aims to experimentally manipulate the design of artificial structures to achieve multipurpose ecological objectives. Artificial structures such as buildings and roads have featured in terrestrial urban landscapes for many years, but have only more recently begun encroaching on aquatic environments. Most marine artificial structures lack the innovative design solutions required to mitigate their ecological impacts and provide essential ecosystem services such as pollution abatement. This project will investigate the efficacy of these designs with both classical measures of diversity and structure and novel measures of ecosystem function. The project aims to provide essential information to inform the design of future marine urban developments.Read moreRead less
The trophic ecosystem of a purpose-built, offshore artificial reef: do coastal currents supply sufficient nutrients for the local production of fish? Offshore artificial reefs may provide enhanced recreational fishing for an urbanized coast. This project will investigate the oceanographic and ecological processes around the new, design-specific, reefs off Sydney to determine if they actually produce fish, rather than simply attract fish. The project will influence the design of future reefs.

Summary
Using food web theory to conserve ecosystems. Species interact with each other and the management of one species can impact on other species. These interactions are often ignored in conservation decision making. Food web theory is the obvious basis for considering links between species when making conservation decisions, but actually contains little explicit guidance for the management of multiple species. Using a novel application of optimisation approaches pioneered in artificial intelligence ....Using food web theory to conserve ecosystems. Species interact with each other and the management of one species can impact on other species. These interactions are often ignored in conservation decision making. Food web theory is the obvious basis for considering links between species when making conservation decisions, but actually contains little explicit guidance for the management of multiple species. Using a novel application of optimisation approaches pioneered in artificial intelligence research, we aim to demonstrate how food web theory can guide the management of multiple species. In doing so, we will also test the effectiveness of widely used approaches to multi-species management, such as keystone species, umbrella species and bottom-up control.Read moreRead less
Do microbial and plant diversity interact to regulate multifunctionality? This project aims to quantify the relative contribution of plant and microbial communities and their interactions on the rate, stability and resilience of ecosystem functions. Plant and soil microbial communities contribute to the functioning of terrestrial ecosystems, driving key processes such as carbon and nutrient cycling. This project will adapt established theories which indicate that greater plant diversity improves ....Do microbial and plant diversity interact to regulate multifunctionality? This project aims to quantify the relative contribution of plant and microbial communities and their interactions on the rate, stability and resilience of ecosystem functions. Plant and soil microbial communities contribute to the functioning of terrestrial ecosystems, driving key processes such as carbon and nutrient cycling. This project will adapt established theories which indicate that greater plant diversity improves ecosystem functions, stability and recovery. The expected outcome is a unifying framework for determining variation in functions across different ecosystem types and environmental disturbance such as rapid climate change.The insight gained into vulnerable ecosystems will help stakeholders (government, conservation, land management) to prioritise the focus on conservation and reduce risks to ecosystem services.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
