Are the sexes really equal? Sex-specific adaptation to environmental change. This project aims to develop a framework for accurately predicting species responses to global change. Many environmental factors will change, and species will evolve, but in a sex-specific manner. Yet understanding of how the sexes vary in their ability to evolve and adapt to such complex environmental change is lacking.

This project aims to develop a framework for accurately predicting species responses to global change. Many environmental factors will change, and species will evolve, but in a sex-specific manner. Yet understanding of how the sexes vary in their ability to evolve and adapt to such complex environmental change is lacking. This project aims to integrate environmental data with the sex-specific evolutionary potential of organisms in response to multiple stressors in a spatially explicit context. The intended outcome is a powerful and general tool for predicting the impact of environmental change on the distribution and abundance of organisms. The benefits include improved conservation outcomes and better pest/disease vector control.Read moreRead less

Genomics and evolution of symbiont transmission in coral reefs. This project aims to understand more deeply the symbiosis between coral and the alga Symbiodinium that underpins the primary productivity, biodiversity and economic impacts of Australia's iconic Great Barrier Reef. Reef-building corals are sustained by symbiosis between the coral and the alga Symbiodinium, and breakdown of symbiosis under environmental stress leads to coral bleaching and death. This project aims to understand how ge ....Genomics and evolution of symbiont transmission in coral reefs. This project aims to understand more deeply the symbiosis between coral and the alga Symbiodinium that underpins the primary productivity, biodiversity and economic impacts of Australia's iconic Great Barrier Reef. Reef-building corals are sustained by symbiosis between the coral and the alga Symbiodinium, and breakdown of symbiosis under environmental stress leads to coral bleaching and death. This project aims to understand how genomes of differently acquired Symbiodinium have evolved to support symbiosis with corals, through sequencing of algal genomes of Symbiodinium. This knowledge will improve the precision in predicting change to inform decision-making strategies in the conservation and restoration of coral reefs.Read moreRead less
How does climate affect regeneration and distribution of Australian plants? This project aims to quantify the degree to which Australian plant species have responded to changes in climate over the last few decades, and to build understanding of the mechanisms that underpin responses to climate change. It seeks to fill critical knowledge gaps about the way heatwaves, freezing temperatures and temperature variability affect plants. The project aims to introduce a novel approach that will allow ass ....How does climate affect regeneration and distribution of Australian plants? This project aims to quantify the degree to which Australian plant species have responded to changes in climate over the last few decades, and to build understanding of the mechanisms that underpin responses to climate change. It seeks to fill critical knowledge gaps about the way heatwaves, freezing temperatures and temperature variability affect plants. The project aims to introduce a novel approach that will allow assessment of physiological and morphological change in response to recent climate change in the absence of historic data. Improved accuracy in identifying species that will have trouble responding to climate change would allow managers to more effectively target their resources to maximise biodiversity and ecosystem function.Read moreRead less

Pheromone attenuation: signal perception in changing atmospheric landscapes. Insects use chemical signals, or pheromones, to communicate with conspecifics. To convey information, the pheromone molecules must pass through the atmosphere and physically interact with receptors, typically located on the antennae of the receiver. Pheromones, like other organic compounds, are degraded by ozone, UV light, and radicals. While we know that pheromone plumes attenuate through the dispersal of molecules, th ....Pheromone attenuation: signal perception in changing atmospheric landscapes. Insects use chemical signals, or pheromones, to communicate with conspecifics. To convey information, the pheromone molecules must pass through the atmosphere and physically interact with receptors, typically located on the antennae of the receiver. Pheromones, like other organic compounds, are degraded by ozone, UV light, and radicals. While we know that pheromone plumes attenuate through the dispersal of molecules, the additional impact of pheromone degradation has been ignored. Our project aims to highlight the significance of odour survival for insect chemical communication by examining how atmospheric conditions, including air pollution, affects signal integrity, antennal morphology and signal perception.Read moreRead less
