Pathways to semelparity versus early maturity in animals and plants. The project aims to resolve an important but unresolved question in life history evolution and ecology- which mechanisms and constraints lead to semelparity (breeding once, which is rare), and which lead to fast life history (breeding early, which is common) in animals and plants. Theory predicts that both may be adaptations to schedules of adult death. Understanding why males and females have either semelparous or fast life hi ....Pathways to semelparity versus early maturity in animals and plants. The project aims to resolve an important but unresolved question in life history evolution and ecology- which mechanisms and constraints lead to semelparity (breeding once, which is rare), and which lead to fast life history (breeding early, which is common) in animals and plants. Theory predicts that both may be adaptations to schedules of adult death. Understanding why males and females have either semelparous or fast life history strategies is crucial to predicting survival of harvested and threatened species under pressure from climate change, drought, predators, and diseases that kill adults. Expected project outcomes include improved ability to address agents of decline of threatened animals and plants including semelparous species.Read moreRead less
Microcosm Experiments for Improved Species Distribution Models. This project aims to use a spatially-explicit experimental system based on protists (microscopic organisms) to evaluate the predictive performance of dynamic distribution models, which are a newly-emerging class of species distribution models. Species distribution models are a fundamental part of ecological science, and underpin a range of applications related to managing threatened and invasive species. The project is expected to p ....Microcosm Experiments for Improved Species Distribution Models. This project aims to use a spatially-explicit experimental system based on protists (microscopic organisms) to evaluate the predictive performance of dynamic distribution models, which are a newly-emerging class of species distribution models. Species distribution models are a fundamental part of ecological science, and underpin a range of applications related to managing threatened and invasive species. The project is expected to provide insights into when these models are likely to work better than more traditional correlative models in non-lab environments. The experiments will inform further development of dynamic distribution models, and help determine whether dynamic distribution models can be usefully applied to species management.Read moreRead less
Working with wind energy and forestry for effective eagle conservation. This project aims to reduce the impacts of wind turbines and disturbance from forestry activity on the Tasmanian wedge-tailed eagle. It will do this by understanding the flight behaviour, movements and mortality of eagles, and the behavioural responses of breeding birds to forestry-related disturbance. The project will build new knowledge and institutional partnerships that will be used to minimise impacts on the Tasmanian e ....Working with wind energy and forestry for effective eagle conservation. This project aims to reduce the impacts of wind turbines and disturbance from forestry activity on the Tasmanian wedge-tailed eagle. It will do this by understanding the flight behaviour, movements and mortality of eagles, and the behavioural responses of breeding birds to forestry-related disturbance. The project will build new knowledge and institutional partnerships that will be used to minimise impacts on the Tasmanian eagle population, and develop models for use in planning. This will safeguard Australia's largest eagle and improve the sustainability of energy and forest industries. This research will also provide a model for the resolution of similar problems elsewhere in the world.Read moreRead less
Choosing to persist: sexual selection in the wild. This project aims to investigate the role of sexual selection in maintaining healthy wild populations. The prevailing story of sexual selection, in which the sexes either compete for or choose the other sex, has been of extravagant ornaments and displays that drive species to extinction. However, an opposing story has emerged, with elaborate ornaments reflecting a healthy genome and sexual selection instead sweeping away damaging genetic mater ....Choosing to persist: sexual selection in the wild. This project aims to investigate the role of sexual selection in maintaining healthy wild populations. The prevailing story of sexual selection, in which the sexes either compete for or choose the other sex, has been of extravagant ornaments and displays that drive species to extinction. However, an opposing story has emerged, with elaborate ornaments reflecting a healthy genome and sexual selection instead sweeping away damaging genetic material. This project expects to generate new knowledge on the potential for sexual selection to remove harmful mutations in the wild. Expected outcomes include determining if sexual selection can help prevent extinction in wild populations, with direct benefits for conservation programs.Read moreRead less

The project aims to develop new ecological theory on local diversity maintenance based on an innovative interaction network model, tested on Western Australian wildflower communities. It is novel in its focus on the complexity of species interactions and their importance to diversity maintenance in nature. This project aims to explore links between plant interaction networks and coexistence theory to provide theoretical expectations for how changes to the environment are expected to alter natural plant communities. It aims to fill theory-gap about mechanisms of multi-species coexistence, advance community ecology, and provide the theoretical foundations necessary for translating ecological theory to restoration and conservation in practice.Read moreRead less

How positive interactions improve predictions of plant community diversity. Though common in nature, the importance of plant-plant facilitation to coexistence and the maintenance of plant diversity at community scales is poorly understood. This project aims to advance understanding of how positive interactions (facilitation) impact on coexistence among plant species as well as local patterns of diversity. To achieve these aims the project will use a combination of field experiments and a compara ....How positive interactions improve predictions of plant community diversity. Though common in nature, the importance of plant-plant facilitation to coexistence and the maintenance of plant diversity at community scales is poorly understood. This project aims to advance understanding of how positive interactions (facilitation) impact on coexistence among plant species as well as local patterns of diversity. To achieve these aims the project will use a combination of field experiments and a comparative analysis of competition and facilitation in Australian, Californian and Spanish annual plant communities with a novel modelling approach for predicting coexistence across variable environments. Outcomes are expected to include an innovative predictive framework of use for plant conservation in Australia and beyond.Read moreRead less
Rapid evolution, and the dynamics and stability of ecological communities. Population sizes of species go up and down and often we do not know why. This is a problem because changes in population size underpin more complex ecological change, and understanding why population sizes change affects our ability to manage environmental impacts, and threatened, harvested and pest species. The aim of this project is to discover how rapid evolution – evolution occurring over just a few generations – driv ....Rapid evolution, and the dynamics and stability of ecological communities. Population sizes of species go up and down and often we do not know why. This is a problem because changes in population size underpin more complex ecological change, and understanding why population sizes change affects our ability to manage environmental impacts, and threatened, harvested and pest species. The aim of this project is to discover how rapid evolution – evolution occurring over just a few generations – drives changes in population sizes of plants in Australian freshwater ecosystems. By focusing on this fundamental yet poorly understood process, our results promise to rewrite our understanding of the causes of change in ecological communities, while highlighting a unique and little studied component of Australia’s biota.Read moreRead less
