Summary
Interplay between plasticity and senescence. This project aims at bridging two fundamental human stressors together in a quantitative genetic framework. The environment changes globally on a huge scale coupled with effect on the age-structures and genetic composition of countless populations by over-harvesting and exploitation. This project will provide significant benefits, such as potential strategies of dealing with future human-induced changes more effectively.
Learning in a changing world: Maternal effects on offspring development and behaviour. The impact of anthropogenic change on Australia's biodiversity is of grave concern. It is therefore vital to understand the capacity of Australian fauna to adapt and change, despite environmental challenges. This project aims to quantify the potential for birds to respond to environmental challenges, by programming offspring with adaptive developmental profiles. By quantifying the effects of maternal stress ov ....Learning in a changing world: Maternal effects on offspring development and behaviour. The impact of anthropogenic change on Australia's biodiversity is of grave concern. It is therefore vital to understand the capacity of Australian fauna to adapt and change, despite environmental challenges. This project aims to quantify the potential for birds to respond to environmental challenges, by programming offspring with adaptive developmental profiles. By quantifying the effects of maternal stress over two generations, this project aims to determine whether mothers have the ability to alter rates of evolutionary change by employing epigenetic mechanisms. Combining lab trials with field data it will determine the biological relevance of these effects to a common, but declining bird, with relevance across Australian avifauna.Read moreRead less

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 consistent individual differences in metabolic rate explain animal personality? Implications for fish and aquaculture in a warming climate. This project will determine if consistent individual differences in metabolic rate affect behaviour, growth, and reproduction in fish. If so, then we need to prepare for the fact that a warming climate will lead to reductions in fish growth and reproduction, because rising temperature directly increases metabolism and therefore maintenance costs.
Climate change: bridging the gap between environmental induced phenotypic change, population dynamics, and long-term evolution. It is becoming impossible to ignore the impact of global climate change on organisms around the world from changes in migration, distribution to extinction events - yet there is much to understand. This project examines the role of a changing environment during developmental and its effects on ecological and evolutionary outcomes.
Adaptive capacity of marine invertebrates in a climate change ocean. As the oceans simultaneously warm and acidify, prospects for marine biota are of concern. This project aims to determine the potential for phenotypic adjustment and evolutionary adaptation. To discern the roles of phenotype and genotype in marine invertebrate stress tolerance this project endeavours to use selection experiments, long-term rearing and quantitative genetics . A focus on vulnerable calcification systems could dete ....Adaptive capacity of marine invertebrates in a climate change ocean. As the oceans simultaneously warm and acidify, prospects for marine biota are of concern. This project aims to determine the potential for phenotypic adjustment and evolutionary adaptation. To discern the roles of phenotype and genotype in marine invertebrate stress tolerance this project endeavours to use selection experiments, long-term rearing and quantitative genetics . A focus on vulnerable calcification systems could determine genetic mechanisms underlying impaired growth. Investigation of species from the east Australia latitudinal thermal gradient, a global change hot spot could generate insights into biological responses and adaptive potential in a changing ocean and on time scales relevant to resource managers to understand the challenges faced by marine biota.Read moreRead less
Comparative Paleogenomics of the Arctic Tundra Ecosystem: the genetic response of plants and animals to climate change. This project will use DNA from deep-frozen seeds and bones 100,000 years old to record how species respond to climate change - by adapting and surviving or by shifting ranges and moving. Very large numbers of genes will be examined to identify changes across the genomes of four plant and two animal species, and contrast the responses to major climatic shifts.
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
The evolutionary biology of seminal fluid. This project will identify proteins within seminal fluid that impact sperm performance and male fertility. The work will derive new insights into the evolution of seminal fluid proteins, while simultaneously exploring how environmental factors such as diet impact male fertility in animals and humans.
