Extrinsic threats and biological predisposition in animal extinction and rediscovery. A global extinction crisis looms, and Australia has a shocking record, especially of mammal extinctions. The results of this project to find how different threats affect each species will lead to management that focusses on species- and region-specific causes. This will help to prevent further extinctions of Australian mammals and other fauna. Many people hope that species of particular importance to us such as ....Extrinsic threats and biological predisposition in animal extinction and rediscovery. A global extinction crisis looms, and Australia has a shocking record, especially of mammal extinctions. The results of this project to find how different threats affect each species will lead to management that focusses on species- and region-specific causes. This will help to prevent further extinctions of Australian mammals and other fauna. Many people hope that species of particular importance to us such as the thylacine have defied extinction, and will be rediscovered. This project will test which predictive factors can increase the chance of species rediscovery, and help management agencies plan for the expected number of future rediscoveries.Read moreRead less
The role of ecological specialisation in insect-plant macroevolutionary processes: a molecular phylogenetic approach across three kingdoms. Flowering plants and phytophagous insects are major components of the world's biodiversity and their evolution has been closely linked. This project will increase our knowledge of insect-endosymbiont-plant interactions and enhance our understanding of the origin, generation and maintenance of much of the world's biodiversity. A broader understanding of how i ....The role of ecological specialisation in insect-plant macroevolutionary processes: a molecular phylogenetic approach across three kingdoms. Flowering plants and phytophagous insects are major components of the world's biodiversity and their evolution has been closely linked. This project will increase our knowledge of insect-endosymbiont-plant interactions and enhance our understanding of the origin, generation and maintenance of much of the world's biodiversity. A broader understanding of how insects, their symbionts and plants have co-evolved should improve our understanding of why and how some insects are able to become pests whereas others do not. Scale insects (the model system in this study) are important pests, both ecologically (Christmas Island interaction between coccids, rainforest plants and crazy ants) and economically (e.g. citrus mealybug).Read moreRead less
Wild eco-evolutionary dynamics: the decline of an iconic Australian bird. This project aims to dissect the ecological and evolutionary processes causing a decline in an iconic Australian bird species. Studies that can properly test explanations for declines in wild populations are rare. This project aims to test how environmental and genetic processes shape individual traits, how these traits determine fitness and how changes in individual fitness affect population dynamics. The project expects ....Wild eco-evolutionary dynamics: the decline of an iconic Australian bird. This project aims to dissect the ecological and evolutionary processes causing a decline in an iconic Australian bird species. Studies that can properly test explanations for declines in wild populations are rare. This project aims to test how environmental and genetic processes shape individual traits, how these traits determine fitness and how changes in individual fitness affect population dynamics. The project expects to provide essential information for the improved management of Australian bird populations, and for understanding the effects of environmental change on natural systems globally.Read moreRead less
