David Bourne has a joint position as a Senior Lecturer at James Cook University in Townsville and Principal Research Scientist at the Australian Institute of Marine Science (AIMS). His training is in the area of molecular microbial ecology with his research focused on investigation of microbial diversity, structure and function in complex ecosystems.He obtained his PhD in 1997 with the research thesis focused on investigating the pathways of bacterial mediated bio-degradation of freshwater cyanobacterial toxins. Postdoctoral positions at the University of Warwick in the UK and the University of Bergen in Norway saw him apply his microbial ecology skills to both terrestrial and marine environments. His research in the UK was focused on understanding terrestrial methanotroph populations while the position in Bergen investigated microbial processes and trophic food webs in marine systems. As a research scientist and senior microbiologist at the Australian Institute of Marine Science (AIMS) his scientific interests and research areas included many aspects of marine science and microbiology including marine microbes for drug discovery and the microbial dynamics in aquaculture (Rock Lobster) larval rearing systems.
Over the last 15 years his research has focused on understanding microbial interactions with corals. This work is divided essentially into two areas, the first investigating the normal microbial communities associated with corals and their functional roles in maintaining coral fitness. The second research focus is to elucidate pathogens and mechanism of disease onset in corals and the implications this has on a stressed reef ecosystem in light of climate change being a major driver of coral reef degradation.
In February 2016, Bourne commenced a Lecturer position at James Cook University, which allows him to maintain a highly dynamic and active research group. This position is joint with AIMS allowing him to continue to mentor a group which includes a number of students and postdoctoral employees all focused on coral microbial interactions and pushing this field ahead with innovative and challenging research projects.

Recovery of the Great Barrier Reef
- Indicative Funding
- $456,818 over 3 years
- Summary
- This project investigates the potential for restoration of reef ecosystems around Magnetic Island. Linked with Earthwatch Australia, it is a citizen science-based project that engages volunteers to help remove macroalgae and monitor changes in coral recruitment, sediment dynamics, community composition, algae regrowth rates, and coral biology, with the hopes that removal of algae leads to an increase in coral cover. This contract represents an extension of the project for a further 3 years.

- Summary
- This project aims to integrate cutting edge genetic and genomic approaches into innovative aquaculture enterprises that farm in tropical northern Australia. It will deliver the requisite genetic knowledge to instigate world-leading and highly productive breeding programs for five species (barramundi, pearl oyster, prawn, grouper and marine seaweed), along with a novel understanding of the genetic basis of disease resistance and how the production environment interfaces with the bacterial microbiome, pathogens and water quality to cause disease. It will increase Australia's capacity to deliver advanced genetics outcomes to the aquaculture sector, while increasing productivity, international competitiveness, and lowered risk due to disease.

Genetic connectivity of Acropora Tenuis coral populations between Magnetic Island and adjacent mid-shelf reefs.
- Indicative Funding
- $5,274 over 1 year
- Summary
- Population declines and isolation can reduce fitness and resilience in coral populations due to low genetic diversity. Reefs surrounding Magnetic Island in the central inshore region of the GBR are categorized as degraded. The dominant reef-building species Acropora tenuis at Magnetic Island may be at risk though their population structure, genetic diversity and connectivity to adjacent reefs is unknown. This knowledge is crucial to underpin the management of local reefs and therefore this project will assess the genetic diversity and connectivity of A. tenuis populations at adjacent reefs surrounding Magnetic Island.

Long term benthic dynamics following interventions on macroalgae dominated reefs
- Indicative Funding
- $4,500 over 1 year
- Summary
- Macroalgae flourish under conditions with high amounts of terrestrial runoff, increased sedimentation and nutrient loading; conditions characteristic of an increasing number of coral reefs globally. These conditions can prompt a shift from coral dominance to an altered, macroalgae-dominated community, with the return of coral dominance rare once fleshy macroalgae have established. By increasing space for growth of existing coral colonies and enhancing available space for coral recruitment, manual removal of macroalgae (?sea-weeding?) has been proposed as one measure to promote reef recovery on macroalgae dominated reefs. This project will monitor the long-term benthic impacts of removing macroalgae from experimental plots on a degraded inshore reef.

Identifying underlying mechanisms facilitating sulphide tolerance in the BBD cyanobacterium Roseofilum reptotaenium
- Indicative Funding
- $4,500 over 1 year
- Summary
- Coral diseases are one of the major threats to reef ecosystems globally. Black band disease (BBD) can cause significant mortality in coral populations during outbreaks. BBD is characterized as a dark pigmented microbial mat that migrates across the coral colony killing underlying tissue rapidly. The microbial mat is dominated by phototrophic cyanobacteria, sulphide-oxidizing bacteria (SOB) and sulphate-reducing bacteria (SRB), which maintain a sulphide-rich and anoxic environment at the lesion interface. Cyanobacteria is generally sensitive to sulphide as it irreversibly blocks the electron transport across photosystem II (PSII), thereby preventing photosynthesis and energy generation by the cyanobacteria. Recent metagenome-enabled transcriptomic analysis provided evidence that BBD-associated cyanobacterium may possess the capacity for metabolic adaptation to sulfidic environments by enhancing light-harvesting capabilities of PSII and PSI, increasing electron transport efficiencies downstream of PSII (e.g. plastocyanin), and increasing the number of PSI reaction centres in the thylakoid membrane. The increased expression of the sqr-gene that governs sulphide-driven anoxygenic photosynthesis was also detected in the sequencing study of Sato et al (2017), providing further evidence for this adaptive mechanism. This project aims to empirically confirm through experimental studies the metabolic and genomic mechanisms that the dominant cyanobacterial strain isolated from BBD lesions facilitates sulphide tolerance.

Ecological implications of macroalgal removal for localised inshore reef restoration
- Indicative Funding
- $5,010 over 1 year
- Summary
- The growing dominance of fleshy macroalgae in many inshore coral reef ecosystems is recognised as a threat to ecosystem functioning and people dependent on coral reefs for their livelihoods. Physically removing macroalgae is proposed as an approach to free up space for coral recovery on algal-dominated reefs. The current state of knowledge surrounding macroalgal removal (reviewed in 2018) highlighted knowledge gaps related to physical and ecological consequences of macroalgal removal. This project aims to improve understanding of the ecosystem-wide impacts of macroalgal removal and determine its potential as a localised restoration strategy for inshore reefs increasingly impacted by anthropogenic threats.

Inter-kingdom signalling in animal health and disease
- Indicative Funding
- $290,608 over 4 years
- Summary
- Animals evolved in a world dominated by bacteria, and it is now clear that intimately associated microbes play critical roles in the development, health and disease of all animals ? from corals to man. To date, animal-microbe interactions have been studied near exclusively in terms of how bacteria affect animals. This proposal seeks to address this bias ? we have discovered a novel mechanism by which the coral Acropora can control its associated bacteria, characterisation of which is central to the present proposal. Understanding how a simple animal manipulates its microbial associates will have major implications, not only for coral disease and resilience, but also for health and disease across the animal kingdom, from corals to man.
