Interests

Research

My research focuses on broad-scale ecological processes and the functional importance of different taxa to the resilience of coral reef ecosystems, in particular the functional role of herbivorous fishes and the dangers of seaweed expansion on coral reefs. I have worked at over 30 locations spanning the world’s tropical oceans and this experience has provided him with considerable insight into the differences among these systems in terms of diversity, reef community structure, human use patterns and, perhaps more importantly, the underlying processes. My current research focuses on understanding the functional importance of different herbivorous fishes in preventing and/or reversing seaweed expansion on coral reefs, the differential responses of herbivorous fishes to changes in the benthic community structure on coral reefs, the recruitment dynamics and replenishment of reef fish populations, and the effects of increasing water temperature on the physiology and function of reef fish.

Coral Reef Health in the Coral Sea Marine Park

Indicative Funding: $968,346 over 3 years
Summary: A number of coral reefs occur in the Australian Marine Parks estate, particularly within the Coral Sea Marine Park (CSMP). In 2016 and 2017, coral reefs in the Great Barrier Reef Marine Park and CSMP were impacted by a mass global coral bleaching event. Regular surveys of coral bleaching and associated reef health in the CSMP are needed to inform future marine park management over the next three years to either enable comparisons against historical baselines where bleaching has previously occurred, or set new baselines for areas that aren?t bleached but may be in the future.

Temperature and seaweed-fish interactions

Indicative Funding: $2,000
Summary: Marine herbivores play a pivotal role in structuring coral reef communities, building resiliency in the face of a changing climate by the mechanical removal of fleshy macroalgae. Ocean warming is currently one of the greatest threats to marine ecosystems. As global climates are changing, understanding how marine flora and fauna interact is a crucial but understudied aspect of how entire ecosystems will respond. The purpose of this study is to assess the effects of increasing temperature on the interaction between tropical marine herbivorous fish and seaweeds. Specifically, as oceans warm, how primary production by seaweeds will scale with consumption by herbivores.

Elizabeth and Middleton Reefs Shallow Reef Monitoring 2018

Indicative Funding: $54,750
Summary: The purpose of this contract is to survey shallow reef environments within the Elizabeth and Middleton reef national Marine Park, to assess the status and trends of reef environments and reef-associated organisms. Surveys will be conducted using methods established during prior surveys, undertaken at Elizabeth and Middleton Reefs in March 2011 and arch 2014.

Australian Museum - Crown-of-Thorns Starfish research grants

Microhabitat preferences and post-settlement demography for juvenile crown-of-thorns starfish (COTS)

Indicative Funding: $35,717
Summary: We will document fine-scale (within reef) variation in the abundance of juvenile (0+ year old) CoTS and relate patterns of abundance to specific features of the local habitat (e.g., depth and aspect) and micro-habitat (eg., cover of different coralline algae and corals) to further refine where to find newly settled CoTS. In areas with high settlement of CoTS, we will also quantify early post-settlement growth and mortality for a single cohort of CoTS, by measuring the local abundance and size structure of juvenile CoTS at selected locations through the course of 1 year.

Updated review of research and monitoring in Australia's Commonwealth Marine Reserves relating to natural values

Indicative Funding: $40,821 over 2 years
Summary: Review and summarise all information (including scientific literature, technical reports and other relevant outputs of scientific research and monitoring) relevant to Australia?s Commonwealth Marine Reserves (CMRs). Relevance to CMRs will be assessed on the basis of geographic overlapping with CMR boundaries and adjacent areas and relevance (eg connectivity) to the CMRs'values, including any literature that links uses or pressures to natural values. All information will be incorporated into an updated CMR research database for the Australian Director of National Parks.

Australian Research Council - Discovery Early Career Researcher Award

Macroalgal-Driven Feedbacks and the Dynamics of Coral Reef Ecosystems

Indicative Funding: $375,000 over 3 years
Summary: Coral reefs are in decline worldwide with many being overgrown by large fleshy macroalgae. While the causes of reef degradation are relatively well established, there is an absence of information on how key ecological processes respond to this degradation. This research will determine how the foraging behaviour of fishes capable of preventing and reversing macroalgal overgrowth, and the replenishment of fish and coral populations are influenced by the composition and density of macroalgal beds. The outcomes will provide a framework for predicting future changes in key processes on coral reefs and will identify temporal windows in which management actions may be most effective; leading to more effective protection of coral reefs.
