Environmentally Induced Non-genetic Effects on Ageing and Fitness over Multi-generations and the Evolution of Life-history Trade-offs. This project will study trade-offs among growth, lifespan and fecundity, and test the following three predictions by employing a short-lived fish model and cutting-edge statistical and computational modelling. First, different dietary conditions not only affect the fitness of the organism, but also that of subsequent generations. Second, different nutritional eff ....Environmentally Induced Non-genetic Effects on Ageing and Fitness over Multi-generations and the Evolution of Life-history Trade-offs. This project will study trade-offs among growth, lifespan and fecundity, and test the following three predictions by employing a short-lived fish model and cutting-edge statistical and computational modelling. First, different dietary conditions not only affect the fitness of the organism, but also that of subsequent generations. Second, different nutritional effects and transgenerational effects on fitness-related traits are underpinned by epigenetic (or non-genetic) modifications. Third, such epigenetic modifications and their inheritance influence the evolution of life-history trade-offs. This project will link the emerging field of epigenetics with evolutionary theory, and reveal mechanisms of transgenerational epigenetic inheritance. Read moreRead less
Combining evolutionary, physiological and molecular approaches to understand ageing and performance. How organisms grow, behave and perform is a result of environmentally triggered molecular, physiological and biochemical reactions. Little is known about how these different levels of organisation interact to create the infinite morphological and behavioural complexities seen in adults. This project aims to integrate the fields of developmental, physiological and evolutionary biology to elucidate ....Combining evolutionary, physiological and molecular approaches to understand ageing and performance. How organisms grow, behave and perform is a result of environmentally triggered molecular, physiological and biochemical reactions. Little is known about how these different levels of organisation interact to create the infinite morphological and behavioural complexities seen in adults. This project aims to integrate the fields of developmental, physiological and evolutionary biology to elucidate how the environment moderates cell and tissue development through gene expression. This will highlight how early developmental decisions affect lifetime energetic trade-offs and efficiency, and how underlying biology manifests into emergent phenomena such as performance, behaviour, ageing and lifespan.Read moreRead less
