  • 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.

Effective sampling of Acanthaster cf. solaris to provide early-warning of new and renewed outbreaks

Indicative Funding
$62,727 over 2 years
This project aims to develop a holistic monitoring program that will not only help to deliver an early-warning syste, but will increase the viability of culling CoTS populations even during non-outbreak periods with the ultimate goal of reducing the frequency and severity of future outbreaks. Perhaps even more importantly, this project will deliver (for the first time) spatially and temporally explicit information about the structure and dynamics of crown-of-thorns starfish within the ?initiation zone? and in the lead-up to a new population irruption, which is a critical knowledge gap that limits understanding of the initiation and causes of population outbreaks.

Coral Sea Marine Park Coral Reef Health Survey (2021)

Indicative Funding
$354,402 over 1 year
The Coral Sea Marine Park (CSMP) covers approximately 990,000 km2 and includes over 30 individual reef systems that are surrounded by deep waters. In March 2020 extensive bleaching of corals was recorded across shallow reef habitats within the CSMP. This project will use surveys of benthic, fish and invertebrate communities to assess the impacts of the 2020 bleaching event on coral reefs within the CSMP.

New York University Abu Dhabi - Research Enhancement Fund

Migrate or hibernate: How do coral reef fishes survive extreme seasonal temperatures in the Arabian Gulf?

Indicative Funding
$30,098 over 2 years (administered by New York University Abu Dhabi)
Seawater temperatures of the Arabian Gulf are among the most extreme and variable in which coral reefs exist, consistently reaching above 36 degrees C in summer and below 14 degrees C in winter. These temperatures present a challenging environment for marine organisms, extending substantially beyond the survivable temperature range of most tropical coral reef fishes worldwide. This project will use implanted acoustic tags to track fish movement and activity patterns and location (presence /absence on the reef) on the reef during summer and winter; and aquarium studies of metabolic activity to determine how these fishes cope with the extreme temperatures in the Arabian Gulf.

Coral Reef Health in the Coral Sea Marine Park

Indicative Funding
$968,346 over 2 years
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.

Distribution, abundance and reproductive behaviour of non-outbreak populations of Acanthaster cf. solaris

Indicative Funding
$23,004 over 1 year
This project will investigate the relative importance of diet regime and reproductive effort on the overall health of the Crown-of-Thorns Starfish. The aim is to determine the underlying causes and mechanisms that lead to population crashes among COTS at the end of major outbreaks, filling the knowledge gap on what naturally regulates abundance of COTS. This will provide valuable data that will be of great help to the selection of areas to be controlled, thereby increasing the efficiency and effectiveness of control activities, ultimately assisting in the management of this species and preventing coral loss.

Temperature and seaweed-fish interactions

Indicative Funding
$2,000 over 1 year
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.

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

Indicative Funding
$35,717 over 1 year
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.
