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.

The effect of habitat degradation on host-parasite interactions in coral reef fish

Indicative Funding: $5,840
Summary: This project will investigate how the degradation of coral reef habitats impacts the abundance and composition of parasites on/within key herbivorous coral reef fish species. In doing so, this study will explore likely changes in the health and condition of these fishes, as reefs continue to degrade. It is hypothesised that parasite community structure will differ largely between healthy and degraded habitats (e.g. coral vs. rubble and macroalgal-dominated habitats), resulting in increased infection by parasites with life histories favoured by degradation, disturbance and reduced habitat. Such changes in parasite community structure are hypothesised to lead to an initial increase in parasite-induced disease epidemics in response to habitat degradation.

Canopy-forming macroalgae on coral reefs: how does it affect key ecosystem processes?

Indicative Funding: $5,000
Summary: Coral reefs are in global decline, with a range of stressors leading to regional reductions in the cover of live corals. While some reefs recover, others are overgrown by fleshy macroalgae such as the canopy-forming Sargassum. Once established, such macroalgal-dominated states are difficult to reverse as positive feedbacks maintain the degraded state. This project will answer the questions: (a) How do clearings in dense beds of macroalgae affect key ecosystem processes such as herbivory and (b) Are herbivorous fishes able to damage or remove Sargassum holdfasts ('root-systems'), thereby preventing canopy-forming macroalgae from regrowing?

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.

Project Title The effect of canopy forming macroalgae on key ecosystem processes on coral reefs

Indicative Funding: $2,500
Summary: Herbivores play an important role in controlling algal biomass on coral reefs, however, different herbivores target different lifestages of algae. Grazing fishes have been hypothesised to prevent the establishment of adult macroalgae by consuming macroalgal juveniles, while browsing fishes consume adult macroalgae. However, the size at which macroalgae transition from being susceptible to grazers vs browsers, and the influence of small-scale habitat features on this relationship are unknown.

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.
