About

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.

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.

Recovery of the Great Barrier Reef

Indicative Funding
$371,000 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. The project is an extension of a previous project which accumulated 7 years of base line data on demographic recovery dynamics of corals at Orpheus Island.

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.

Recovery of the Great Barrier Reef

Indicative Funding
$165,000 over 2 years
Summary
This project investigates the recovery of reef ecosystems around Orpheus Island. Linked with Earthwatch Australia, it is a citizen science based project that engages volunteers to help survey the recovery of corals that have suffered major ecological disturbances including a severe category cyclone in 2011 and two major bleaching events in 2016 and 2017. To date the project has accumulated 7 years of base line demographic recovery dynamics of corals. It also investigates disease process on the reefs around Orpheus Island specifically looking at black band and elucidating the ecological and microbial drivers of disease outbreaks.

Reviewing microbial communities on the GBR: contribution to a functioning reef

Indicative Funding
$25,000
Summary
Marine microorganisms drive all globally important biogeochemical cycles, underpin the health of marine ecosystems and are the first biological responders to environmental perturbation. Through benthic pelagic coupling, and host associated interactions, the marine microbes contribute directly and indirectly to reef functioning. Within reef systems of the GBR however we have very little understanding on how microbes provide resilience and buffering in the system or contribute to processes that lead to tipping points and changed ecosystem structure and function. The project will be a desktop study and review that looks across all relevant literature to assess the microbial taxonomic and functional groups that contribute to a functioning reef. It will assess microbes that are implicated in healthy reef functioning and contrast with microbes in disturbed environments. This analysis will build on current knowledge from all reef systems and aquarium studies and made relevant to the GBR conditions. Considering the unique environment of the GBR with reefs spread across longitudinal temperature gradients and across a water quality gradient, the study will assess reef microbes across these gradients using information delivered from eReefs.

Genome-level insight into the dynamics of a model coral microbiome

Indicative Funding
$120,000 over 3 years (administered by UQ)
Summary
Microorganisms form an intimate symbiotic relationship with corals and are critical to their health. However, the microbiome can be disrupted by environmental perturbations, including higher than normal ocean temperatures, leaving the coral susceptible to disease and bleaching. Currently, our understanding of how the microbiome composition and metabolic function change in response to seasonal temperature variation and disease is limited. Here, we will examine the structural and functional microbiome dynamics in an ecologically important coral on the Great Barrier Reef along a natural temperature gradient. This will provide insight into the role the microbiome plays in maintaining coral health.
