Summary
Larval dispersal: the critical connection in coral reef recovery. This project will document how larval exchange connects populations of reef-building corals in the Great Barrier Reef World Heritage Area using an innovative approach that combines genomics with modelling tools. Predictions will be tested by genetically monitoring the recovery of coral populations on reefs destroyed by Cyclone Yasi.
Tracking origins and spread of Crown-of-Thorns Seastars on the Great Barrier Reef. This proposal aims to uncover the source reefs for Crown-of-Thorns Seastars (CoTS) outbreaks and the main routes of spread through the Great Barrier Reef. Coral eating CoTS pose a significant threat to the Great Barrier Reef. Using population genomics, invasive species genetics, and epidemiology and drawing upon extensive collections of adults and larvae dating from the 1980’s onwards, this project will test promi ....Tracking origins and spread of Crown-of-Thorns Seastars on the Great Barrier Reef. This proposal aims to uncover the source reefs for Crown-of-Thorns Seastars (CoTS) outbreaks and the main routes of spread through the Great Barrier Reef. Coral eating CoTS pose a significant threat to the Great Barrier Reef. Using population genomics, invasive species genetics, and epidemiology and drawing upon extensive collections of adults and larvae dating from the 1980’s onwards, this project will test prominent hypotheses about outbreak origins and subsequent spatial spread of CoTS via larval dispersal. The project expects to clarify the locations and timing of long distance dispersal pathways and to test whether larval detection near reefs can provide an early warning for local outbreaks on these same reefs.Read moreRead less

Establishing genetic guidelines for the effective ecological restoration of seagrass meadows. Industry and coastal development in Australia are of national importance for economic growth and prosperity, but they threaten benthic habitats, like seagrasses. Loss of seagrass meadows without mitigation results in greater coastal impacts from damaging storms and waves and a reduction in the health and productivity of marine environments globally. Thus the ecological restoration of seagrass meadows is ....Establishing genetic guidelines for the effective ecological restoration of seagrass meadows. Industry and coastal development in Australia are of national importance for economic growth and prosperity, but they threaten benthic habitats, like seagrasses. Loss of seagrass meadows without mitigation results in greater coastal impacts from damaging storms and waves and a reduction in the health and productivity of marine environments globally. Thus the ecological restoration of seagrass meadows is an urgent national priority action that involves industry, government and the community. Through the detailed assessment of population genetic variation and key population processes in seagrasses, this project will establish genetic guidelines for a more effective seagrass restoration industry.Read moreRead less

This project aims to predict the future of coral reefs in the rapidly changing climate of the Anthropocene by integrating state-of-the-art population genomics with evolutionary and ecological modelling. The project expects to describe pathways of genetic and non-genetic adaptation; and the strength and direction of connectivity of warm vs cold adapted coral populations - united in an eco-evolutionary framework. Expected outcomes address critical gaps in data and methodology that currently hinder our ability to reliably model the evolutionary and ecological dynamics of one of the most biologically diverse, socially and economically valuable and climatically vulnerable ecosystems of our planet, contributing to their science-based management.

Saving seagrass from climate change. This research aims to test whether seagrass ecosystems can be safeguarded from climate change impacts by enhancing genetic connectivity in range edge populations using novel genetic rescue approaches. We will use the range edge seagrass meadows of the UNESCO World Heritage Site of Shark Bay as our model, which was significantly impacted by a marine heat wave in 2010/2011. The project will generate new knowledge on how seagrasses can adapt and survive in situ. ....Saving seagrass from climate change.

Coral reefs are sustained by symbiosis between the coral host and dinoflagellates of genus Symbiodinium. Breakdown of this symbiosis under environmental stress results in coral bleaching and eventual death. This project aims to understand how dinoflagellate genomes have evolved to support a symbiotic lifestyle. The project aims to sequence genomes of Symbiodinium from reef corals and other hosts, and two free-living relatives. This should enable the identification of genes that have been gained or lost, or are under adaptive selection. This genome-scale perspective on the molecular systems implicated in the evolution of this symbiotic lifestyle has potential to inform strategies for preserving Australia's Great Barrier Reef in the face of climate variations.Read moreRead less
