Prof Morgan Pratchett has broad interests in population and community ecology of coral reef organisms, especially corals and fishes. His current research focuses on major disturbances that impact coral reef ecosystems, with a view to understanding differential responses and vulnerabilities among coral reef organisms.

Morgan has written many papers describing direct and indirect effects of coral bleaching and outbreaks of crown-of-thorns starfish, considering impacts on both coral assemblages and associated assemblages of coral reef fishes. He has also conducted extensive research on the biology and ecology of coral reef butterflyfishes.

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.

ARC Centre of Excellence for Integrated Coral Reef Studies

Indicative Funding
$28,000,000 over 7 years
The overarching aim of the ARC Centre of Excellence for Integrated Coral Reef Studies is to provide the scientific knowledge necessary for sustaining ecosystem goods and services of the world's coral reefs, which support the livelihoods and food security of millions of people in the tropics. The Centre will enhance Australia's global leadership in coral reef science through three ambitious research programs addressing the future of coral reefs and their ability to adapt to change. A key outcome of the research will be providing tangible benefits to all Australians by bui8lding bridges between the natural and social sciences, strengthening capacity, and informing and supporting transformative changes in coral reef governance and management.

Early detection of Crown-of-Thorns starfish recruitment using settlement traps and genetic analyses

Indicative Funding
Major knowledge gaps remain around the settlement and early post-settlement stages of Crown-of-Thorns starfish (CoTS). Early detection of large settlement pulses provides our best chance to potentially stop future CoTS outbreaks. Our recent work has shown that CoTS larvae settled to our custom-built settlement traps. In order to detect settlement, genetic analyses were developed to analyse the samples. The aim is to additionally use new innovative analyses that will allow us to compare settlement rates at different time points, reefs, sites and depths. More traps will also be deployed during the next spawning season to improve our understanding of settlement preferences and test the traps as an early warning system on reefs not subject to outbreaks yet.

Crown-of-thorns starfish: surveillance and life history

Indicative Funding
$150,000 over 2 years (administered by CSIRO)
This project supports the implementation of the NESP Crown-of-Thorns Starfish Integrated Pest Management Project's management and research strategy by i) describing ecological parameters key to parameterizing the tools underpinning the management strategy, ii) analysing existing data sets to assess management performance and describe the interaction between CoTS and bleaching, and , iii) scoping new technologies and surveillance strategies for detecting and monitoring primary and secondary outbreaks. The work will involve a combination of field ecological research, statistical analysis of existing data, technology and strategy development (the latter through workshops) and inform decision making through incorporation into decision support tools and recommendations.

Coral Reef Health in the Coral Sea Marine Park

Indicative Funding
$968,346 over 3 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.

Implementation of the Crown of Thorn Starfish research strategy: regional strategies

Indicative Funding
$85,000 over 4 years (administered by CSIRO)
Crown-of-Thorns starfish (COTS) management requires decisions be made about where to invest control effort in order to achieve regional scale objectives, e.g. to modify COTRS spread or to facilitate coral recovery. However, no objective basis for choosing sites exists, beyond their economic importance, meaning that achieving these important goals is largely left to chance. This project will leverage past and current research to develop a decision support framework to assist in prioritizing reefs for control and for assessing alternative strategies by integrating the full range of ecological and management information available. Field and desktop research will also be conducted to fill critical knowledge gaps and to assess the prospects of new control technologies.

Fisheries Research & Development Corporation - Annual Competitive Round

Establishing baselines and assessing vulnerability of commercially harvested corals across northern Australia

Indicative Funding
$384,300 over 6 years (administered by JCU)
This project is critically important to provide necessary data on the distribution, abundance and biology of commonly harvested corals across northern Australia, both to ensure that current harvest levels and practices are sustainable and address legislative requirements for harvesting and exporting species listed under the Convention on International Trade in Endangered Species (CITES).

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

Indicative Funding
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.

Abundance, Species Identify and Resilience of Inshore Corals in the Dampier Archipelago

Indicative Funding
$150,000 over 4 years
The study will undertake fisheries-independent assessments of the abundance and composition of corals in near shore environments across the Dampier Archipelago. Importantly, detailed sampling will be combined with genetic sampling and analysis to unequivocally establish the species identity of corals, as required for aligning catch data with scientific information on the vulnerability of different coral species. This project will provide important baseline information on the ecological and economic importance of near shore coral assemblages and contribute to the development of monitoring protocols necessary to ensure on-going harvesting is sustainable, even in the face of climate change.

The impact of increasing ocean temperatures on the movement and behaviour of the iconic Indo-Pacific fisheries species, coral trout

Indicative Funding
$38,815 over 2 years
Ocean warming is the most pervasive aspect of climate change, which impacts directly on the distribution, abundance, and population structure of fishes, as well as the viability and sustainability of fisheries. Tropical marine fishes are particularly vulnerable to ocean warming, because species are already exposed to summer temperatures that may have negative consequences for individual condition and fitness. Coral trout are among the most important tropical marine fisheries species, targeted by commercial and artisanal fishers throughout the Indo-Pacific. This study will explore if, and how coral trout mediate or acclimate to extreme temperatures, with a view to better understand the impacts of climate change on wild stocks of these important fishes.
