Summary
Identifying factors that counter negative impacts of ocean climate change. This project aims to identify factors that counter the negative impacts of climate change on coral reefs. This project expects to address key research gaps to ensure the persistence of these ecosystems. Expected outcomes of this project include identification of coral reefs that are buffered by adjacent systems, such as mangroves and seagrass, and characterisation of conditions (e.g. increased food availability) that allo ....Identifying factors that counter negative impacts of ocean climate change. This project aims to identify factors that counter the negative impacts of climate change on coral reefs. This project expects to address key research gaps to ensure the persistence of these ecosystems. Expected outcomes of this project include identification of coral reefs that are buffered by adjacent systems, such as mangroves and seagrass, and characterisation of conditions (e.g. increased food availability) that allow coral reefs and associated organisms to persist under stress. Outcomes of this project should provide significant benefits such as adding to the interventions toolbox in alleviating the impacts of global change on coral reefs and identifying conservation strategies to help prevent the loss of these valuable ecosystems.Read moreRead less
Can endosymbionts alter climate change resilience in insects? This project aims to establish whether endosymbionts alter climate change vulnerability and investigate the potential for endosymbionts to be used as a tool to modify climate change resilience in insects. Heritable endosymbionts – microscopic bacteria living exclusively within host cells – are widespread in insects. A handful of studies indicate that endosymbionts may influence the thermal tolerance of their host, yet whether they al ....Can endosymbionts alter climate change resilience in insects? This project aims to establish whether endosymbionts alter climate change vulnerability and investigate the potential for endosymbionts to be used as a tool to modify climate change resilience in insects. Heritable endosymbionts – microscopic bacteria living exclusively within host cells – are widespread in insects. A handful of studies indicate that endosymbionts may influence the thermal tolerance of their host, yet whether they alter the upper thermal limits and climate change risk of insects is unknown. This fellowship will provide a greater understanding of the consequences of climate change on species persistence, as well as opening up avenues to utilise endosymbionts as a tool to manipulate the climate change resilience of insects.

Sexual conflict and the evolution of nuptial gifts. This project aims to understand how sexual conflict drives the evolution of “manipulative” nuptial gifts in male arthropods and how females respond to ingesting these gifts. Nuptial food gifts comprise materials (other than sperm) that are offered by males to females to consume at mating, and are an integral feature of the mating systems of a wide variety of arthropods. The project will study the decorated cricket, a species where males produce ....Sexual conflict and the evolution of nuptial gifts.

Nuptial food gifts comprise materials (other than sperm) that are offered by males to females to consume at mating, and are an integral feature of the mating systems of a wide variety of arthropods. The project will study the decorated cricket, a species where males produce a nuptial food gift that contains a cocktail of chemicals known to influence female reproduction when eaten. The project is expected to strengthen Australia’s international standing in evolutionary research and help train the next generation of evolutionary biologists.Read moreRead less
Interacting with change: inter-specific competition and climate change . The project aims to understand how species will adapt to climate change by examining a largely overlooked process: how competition shapes evolutionary responses. Rising temperatures will fundamentally alter where species live, re-shuffling communities. Yet, how changes in community composition will affect the way current assessments of species vulnerability to climate change is generally unknown. Expected outcomes include i ....Interacting with change: inter-specific competition and climate change . The project aims to understand how species will adapt to climate change by examining a largely overlooked process: how competition shapes evolutionary responses. Rising temperatures will fundamentally alter where species live, re-shuffling communities. Yet, how changes in community composition will affect the way current assessments of species vulnerability to climate change is generally unknown. Expected outcomes include improved species models for predicting responses to climate change through the integration of competitive effects with environmental data. The benefit will be an increased accuracy in predictions of species at risk to climate change which will guide policy and management decisions to protect vulnerable environments better.Read moreRead less
Oyster adaptation to climate change via transgenerational plasticity. We are in an age of rapid climate change, where the need to understand the adaptive potential of marine organisms in warmer, more acidified oceans is increasingly urgent. This is especially true in Australia where changes are significant. This project uses a cutting-edge, integrated interdisciplinary approach to measure the capacity of oysters to adapt and persist to climate change via transgenerational plasticity, describe th ....Oyster adaptation to climate change via transgenerational plasticity. We are in an age of rapid climate change, where the need to understand the adaptive potential of marine organisms in warmer, more acidified oceans is increasingly urgent. This is especially true in Australia where changes are significant. This project uses a cutting-edge, integrated interdisciplinary approach to measure the capacity of oysters to adapt and persist to climate change via transgenerational plasticity, describe the epigenetic mechanisms which underlie it and develop an immediate breeding method to protect vulnerable oysters and other marine organisms against climate change. The research outcomes will transform Indigenous-led oyster reef restoration projects and future-proof an iconic food source and national industry.Read moreRead less

Summary
Sexual conflict and evolutionary dynamics of insecticide resistance genes. This project aims to develop new approaches to mitigate resistance evolution by applying sexual selection theory to predict evolution of insecticide resistance in flies. A key assumption of current agriculture management strategies is that resistance carries fecundity or survival costs, but this is rarely demonstrated, especially in nature. Not all resistance mutations are novel; many represent pre-existing variants maint ....Sexual conflict and evolutionary dynamics of insecticide resistance genes. This project aims to develop new approaches to mitigate resistance evolution by applying sexual selection theory to predict evolution of insecticide resistance in flies. A key assumption of current agriculture management strategies is that resistance carries fecundity or survival costs, but this is rarely demonstrated, especially in nature. Not all resistance mutations are novel; many represent pre-existing variants maintained by balancing selection i.e. opposing effects in males and females, or by environmental fluctuations. This research will provide new insight into how resistance evolves and is maintained in natural populations and may result in potential reduction in pesticide use with associated economic and biodiversity benefits.

Evolutionary impacts of gene interactions in a rapidly changing world. This project aims to understand how gene interactions impact evolution in our warming marine environments. The role of gene interactions is controversial because they are assumed to have little effect on genetic variation for fitness in natural populations. Yet new data show that this effect can be substantial and is enhanced by heat stress, explaining most of the genetic variation available for evolution under stressful cond ....Evolutionary impacts of gene interactions in a rapidly changing world. This project aims to understand how gene interactions impact evolution in our warming marine environments. The role of gene interactions is controversial because they are assumed to have little effect on genetic variation for fitness in natural populations. Yet new data show that this effect can be substantial and is enhanced by heat stress, explaining most of the genetic variation available for evolution under stressful conditions. The project aims to use quantitative genetics, genomics, and theory to determine the evolutionary impacts on marine populations facing rapid ocean warming in southeast Australia. The outcomes could change how we view gene interactions, and help us to better predict biological responses to environmental change.Read moreRead less
Linking sex-specific adaptation to the evolution of infectious disease.

This project aims to examine how differences in the response of males and females to pathogen attack can influence the evolution of infectious disease. This project expects to generate new knowledge in the area of host-pathogen co-evolution, by integrating approaches from the fields of evolutionary genetics, sexual selection, and epidemiology. Expected outcomes include an enhanced capacity to build interdisciplinary collaborations and development of theory that predicts infection dynamics in any species with separate sexes. This is expected to provide significant benefits, such as improving our knowledge of why the sexes differ and potentially providing new avenues for understanding disease outbreaks and preventing population declines or extinctions.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.

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
