About

Dr. Hugo Harrison is a molecular ecologist with an interest in coral reefs, notably movement ecology of coral reef organisms. His main research is focused on understanding patterns of larval connectivity in coral reef fish, and its relevance to the design and effectiveness of marine protected areas.

Dr. Harrison received his doctoral degree cum laude in Marine Biology from James Cook University in Australia and the Ecole Pratique des Hautes Etude in France in 2014.  As part of his thesis, Dr. Harrison and colleagues were the first to apply a forensic DNA profiling approach to track the dispersal pathways of fish larvae throughout a network of marine reserves on Australia’s Great Barrier Reefs. Their study provides the first conclusive evidence that larval supply from marine reserves generates important recruitment subsidies to both fished and protected areas.

His expertise lies in combining field-based research with advances in molecular genetics to investigate dispersal and connectivity in coral reef seascapes, which are fundamental to the persistence and effective management of reef ecosystems globally. In 2016, he was awarded a prestigious ARC Discovery Research Fellowship (DECRA) to identify “Critical regions and network connectivity of coral reef ecosystems”.

He now leads a diverse research portfolio on 'Adaptive Seascapes' to investigate coral reefs' adaptive potential to climate change. His research interests span genomics and population genetics, biophysical and metapopulation modelling, as well as species life-history and ecosystem dynamics.

The influence of symbiont genetic diversity on thermally distinct coral reefs

Indicative Funding
$2,500 over 1 year
Summary
This project aims to assess how symbiont genetic diversity underpins thermally distinct coral populations. Standardised heat stress experiments have revealed high variability in reef-level thermal tolerance. To complement phenotypic assessments, genomic analyses of symbiont communities will elucidate the role of symbionts in shaping heat tolerance thresholds. Understanding how symbiotic diversity contributes to thermal tolerance in corals will provide evidence of the ecological and adaptive processes in the symbiotic partnership of critically threatened coral reefs. This project will also provide the first study of symbiont biogeography in the Coral Sea Marine Park region to date.

Indicative Funding

Summary
This project aims to identify the environmental, physiological and genetic processes that underpin heat tolerance in corals. This will contribute to our understanding of whether coral populations will be able to adapt to a changing climate. Standardised heat stress experiments will be used to quantify heat tolerance in corals across geographical gradients to identify variation among populations, environmental and disturbance regimes. Complementary molecular approaches will investigate the genetic basis of both host and symbiont partners. This research will contribute to the protection of reef biodiversity into the future.

Coral Sea Marine Park Coral Reef Health Survey (2021)

Indicative Funding
$354,402 over 1 year
Summary
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.

Coral Sea - Coral Reef Health Multi Year Project

Indicative Funding
$45,455 over 2 years
Summary
The principal output of this project will be providing spatial and temporal analyses of hydrodynamic patterns in the Coral Sea Marine Park (CSMP) to facilitate planning and establishment and/or revisions of existing management plans. This project will inform patterns of connectivity and circulation flow across the broader CSMP, and between CSMP and Great Barrier Reef Marine Park using existing modelling platforms.

Coral Reef Health in the Coral Sea Marine Park

Indicative Funding
$968,346 over 2 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.

Critical regions and network connectivity of coral reef ecosystems

Indicative Funding
$366,000 over 3 years
Summary
The movement of individuals in fragmented landscapes plays a central role in the ecology and evolution of species. This Project aims to measure the degree of connectivity between isolated reefs in Australia's Coral Sea and the Great Barrier Reef and identify the biological and environmental mechanisms that enhance management strategies or mitigate against disturbances. It will be the first study to measure true connectivity at multiple scales and identify critical regions for the design of networks of marine protected areas. This Project will significantly improve our understanding of connectivity in marine seascapes and directly benefit fisheries management and coral reef conservation.
