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

The genetic code of native plants are yet to be explored for DNA elements that promote resilience to climate change. These elements are now ripe for discovery due to recent advances in epigenomics allowing for rapid identification. This proposal aims to discover heat-associated elements in waxy bluebells, which inhabit Australia’s vulnerable high country. Expected outcomes include new insights on gene regulatory mechanisms in native plants; the generation of resources for genetic conservation, and catalysing further molecular research into Australian flora. This should provide significant benefits by revealing genome regulation in native plants, thereby improving the ability to predict the impacts of climate change.Read moreRead less
Predicting adaptation and range expansion under climate change. This project investigates the repeatability and thereby the predictability of adaptation to climate change by leveraging 1000 genomes sampled over 150 years and multiple climatic gradients in the rapidly adapting, globally invasive, and highly allergenic ragweed. We expect to deepen our understanding of the genetic basis of adaptation and decipher the circumstances under which adaptive genetic change is repeatable, by integrating a ....Predicting adaptation and range expansion under climate change. This project investigates the repeatability and thereby the predictability of adaptation to climate change by leveraging 1000 genomes sampled over 150 years and multiple climatic gradients in the rapidly adapting, globally invasive, and highly allergenic ragweed. We expect to deepen our understanding of the genetic basis of adaptation and decipher the circumstances under which adaptive genetic change is repeatable, by integrating a novel evolutionary model with genomic data. We will develop the capacity to predict species’ distributions and trait evolution under climate change using a powerful empirical dataset. This will provide us with the capacity to anticipate and manage the effects of climate change on noxious and threatened species.Read moreRead less
Some like it hot: invasive species, hybridisation, and a warming world. Temperatures are rising and invasive species are becoming more prevalent.

Temperatures are rising and invasive species are becoming more prevalent. This project aims to understand how climate change and hybridisation between exotic and native marine species leads to rapid adaptation. Using integrative approaches from genomics and physiology and focusing on Australian blue mussels, this proposal will test leading hypotheses about how climate change and hybridisation can enable rapid adaptation and the spread of exotic species. Outcomes will include strategies for minimising impacts of invasive mussels and boosting warm-temperature adaptation in aquaculture mussels and restored shellfish reefs. This project will yield fundamental insights into how marine species can quickly adapt to warming seas.Read moreRead less
Multilevel selection and the integrity of mitochondrial DNA. This project aims to investigate the evolutionary conundrum of how and why organelles remain asexual. The widespread occurrence of sexual reproduction suggests that sex is beneficial to organisms. Yet we all carry an ancient genome that never had sex, the mitochondrial genome (mtDNA). Theory predicts that mtDNA should no longer exist, because without sex it accumulates deleterious mutations and cannot accumulate beneficial ones. Yet mt ....Multilevel selection and the integrity of mitochondrial DNA. This project aims to investigate the evolutionary conundrum of how and why organelles remain asexual. The widespread occurrence of sexual reproduction suggests that sex is beneficial to organisms. Yet we all carry an ancient genome that never had sex, the mitochondrial genome (mtDNA). Theory predicts that mtDNA should no longer exist, because without sex it accumulates deleterious mutations and cannot accumulate beneficial ones. Yet mtDNA does not suffer mutational meltdown and is shown to adapt. This project will explain how, proposing that the combination of two traits, uniparental inheritance and multiple genomes per cell, make up for the lack of sex. This project expects to provide an explanation for the evolutionary question of what keeps mitochondria healthy, important as mitochondria affect ageing and health.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.

The genetic link between local adaptation and speciation. Darwin believed that natural selection drove the origin of new species, or speciation. However, research on speciation during the 20th century shifted focus from studying adaptation within a population to examining the causes of reproductive isolation (lack of interbreeding) between populations. This Project aims to unify our understanding of adaptation and reproductive isolation by examining their shared heredity. Using an established sy ....The genetic link between local adaptation and speciation. Darwin believed that natural selection drove the origin of new species, or speciation. However, research on speciation during the 20th century shifted focus from studying adaptation within a population to examining the causes of reproductive isolation (lack of interbreeding) between populations. This Project aims to unify our understanding of adaptation and reproductive isolation by examining their shared heredity. Using an established system in natural conditions, this project will generate new knowledge on the genetic processes driving speciation. This interdisciplinary research will clarify how biodiversity originates with implications for crops, conservation biology and species responses to environmental change.Read moreRead less
