Adaptation by DNA download: Experimental evolution of a pangenome. This project aims to understand how microbes adapt when they can directly “download" new genes from their surrounding environment, or from other types of bacteria. Specifically, the proposed research will carry out the largest-scale measurements of the fitness effects of horizontally transferred genetic variation, to discover how each of these genes interacts with the environment, and with other genes.

Fitness and evolutionary consequences of developmental plasticity. This project aims to develop a framework for accurately predicting species responses to global change. Phenotypic plasticity will act as a rapid-response mechanism, enabling organisms to survive climatic shifts in the first instance. Understanding how and when plasticity underpins species’ persistence under climate change is lacking. This project aims to integrate developmental responses to environmental change with evolutionary ....Fitness and evolutionary consequences of developmental plasticity. This project aims to develop a framework for accurately predicting species responses to global change. Phenotypic plasticity will act as a rapid-response mechanism, enabling organisms to survive climatic shifts in the first instance. Understanding how and when plasticity underpins species’ persistence under climate change is lacking. This project aims to integrate developmental responses to environmental change with evolutionary adaptation and population persistence 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. Benefits include improved conservation outcomes and better control of pest/disease vectors.Read moreRead less

How beetles harness near-infrared properties to enhance energy efficiency. This project aims to discover how animals use nanophotonic structures to manipulate near infra-red light for thermal control and visual information. Almost nothing is currently known about the mechanism, function and evolution of near-infrared properties in animals, despite their potential importance for maintaining body temperatures within the critical thermal limits for survival.

This project aims to discover how animals use nanophotonic structures to manipulate near infra-red light for thermal control and visual information. Almost nothing is currently known about the mechanism, function and evolution of near-infrared properties in animals, despite their potential importance for maintaining body temperatures within the critical thermal limits for survival. The project uses multidisciplinary techniques from optical physics, physiology and evolutionary biology to reveal near-infrared adaptations in socially and economically important Christmas beetles. The intended outcomes include a bio-informed blueprint for a new class of functional nanomaterials that enhance energy efficiency.Read moreRead less

This project aims to investigate changes to native bee cognition, morphology, and pollination capability in response to climatic warming. Using emerging experimental methods for behavioural testing and state-of-the-art 3D modelling of museum specimens, the project expects to identify which species are likely to experience change under future climate scenarios. This project expects to determine if increased temperatures cause pollination deficits through impaired bee cognition and changed morphology. The knowledge gained in this project will allow us to identify vulnerable species and develop strategies across agriculture, government, and community sectors to support pollination and inform conservation priorities.Read moreRead less
