The coexistence of antibiotic resistant and sensitive bacteria in microbial communities represents a paradox. Combining novel ecological models and competition experiments, this project aims to investigate how the pulsing of antibiotics and resources affects the coexistence of resistant and sensitive bacteria. This project expects to generate new knowledge into how the complex non-equilibrium dynamics of natural systems feeds back to regulate the spread of antibiotic resistance in microbial communities. This should advance our fundamental understanding of microbial competition, and provide a foundation for the development of new ecologically-aware strategies for managing resistance.Read moreRead less
Dispersal and recruitment of species across landscapes: a new synthesis. This project aims to ask: does failure to disperse successfully across landscapes limit the abundances and diversity of species in habitat patches? This is a central question in ecology. The project expects to generate new knowledge about the links between dispersal success and population numbers by using recent advances in river ecology that have overcome logistical barriers to hypothesis tests. Expected outcomes include n ....Dispersal and recruitment of species across landscapes: a new synthesis. This project aims to ask: does failure to disperse successfully across landscapes limit the abundances and diversity of species in habitat patches? This is a central question in ecology. The project expects to generate new knowledge about the links between dispersal success and population numbers by using recent advances in river ecology that have overcome logistical barriers to hypothesis tests. Expected outcomes include new insights into why dispersal failures occur and how they are associated with low population numbers. Benefits should include improved advice to conservation managers about extinction risks, and unique, tangible outcomes for fundamental ecological research in Australia that will spring from international collaboration.Read moreRead less
Diversity maintenance in patchy environments. This project aims to advance understanding of species coexistence and diversity maintenance in complex natural environments. Though diversity varies across patchy natural and human-created environments, the mechanistic drivers of these patterns remain poorly understood. This knowledge gap limits our ability to predict and manage responses of natural communities to environmental changes. Using data from threatened Western Australian wildflower communi ....Diversity maintenance in patchy environments. This project aims to advance understanding of species coexistence and diversity maintenance in complex natural environments. Though diversity varies across patchy natural and human-created environments, the mechanistic drivers of these patterns remain poorly understood. This knowledge gap limits our ability to predict and manage responses of natural communities to environmental changes. Using data from threatened Western Australian wildflower communities and novel ecological models of species coexistence, the project aims to deliver a mechanistic understanding of biological diversity, and provide fundamental knowledge needed to improve ecosystem management and restoration outcomes across Australia and globally.Read moreRead less

The role of drought-stress and insect attack on rainforest plant health. This project aims to examine the vulnerability of tropical plants to drought and insect attack in a large-scale field experiment. We will pioneer a new research approach that focuses on the causes and stages of decline in plant health prior to death, in order to identify the characteristics of plant species that make them more susceptible to drought and insect attack. Expected outcomes of this project include an improved ca ....The role of drought-stress and insect attack on rainforest plant health.

We will pioneer a new research approach that focuses on the causes and stages of decline in plant health prior to death, in order to identify the characteristics of plant species that make them more susceptible to drought and insect attack. Expected outcomes of this project include an improved capacity to predict the function and composition of future forests. This project will provide significant benefits to communities concerned with the direct and indirect effects of droughts in protected areas, forestry reserves and agriculture. Read moreRead less
Designing green spaces for biodiversity and human well-being. Designing green spaces for biodiversity and human well-being . This project aims to determine mechanisms linking urban design to socio-ecological benefits from green spaces. Ecological restoration in urban green space could attract more biodiversity into urban environments, reduce maintenance costs, provide market advantage for the development industry and improve a sense of place for residents. However, how best to encourage biodiver ....Designing green spaces for biodiversity and human well-being. Designing green spaces for biodiversity and human well-being . This project aims to determine mechanisms linking urban design to socio-ecological benefits from green spaces. Ecological restoration in urban green space could attract more biodiversity into urban environments, reduce maintenance costs, provide market advantage for the development industry and improve a sense of place for residents. However, how best to encourage biodiversity using urban design is poorly understood, and little is known about how green spaces create health and well-being. This project will alter levels of green space design explanatory variables in modular experimental plots, in both Royal Park, the City of Melbourne’s largest public green space, and Melbourne’s CBD; conduct biodiversity and human wellbeing experiments; and develop urban design recommendations that support biodiversity and human wellbeing.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

This project aims to quantify the species traits and environmental conditions that enable wildlife to persist in an increasingly urbanised world. Through developing and testing a framework linking unprecedented urban expansion and biodiversity change, this project will identify favourable conditions that support biodiversity in the face of global urbanisation. Project outcomes will inform appropriate real-world management actions and equip scientists, policy-makers and planners with tools to forecast the persistence of biodiversity in Australian cities. By discovering the attributes species need to survive city life this project will help prevent future catastrophic declines of global biodiversity in our increasingly urbanised world.Read moreRead less

This proposal aims to develop a framework for statistical modelling that integrates across spatial scales and disentangles the processes of environmental tolerance, biotic interactions and dispersal. Understanding the processes that drive species distributions and ecological communities is central to ecology and environmental management. This knowledge can be used to anticipate the impacts of environmental change on ecosystems, and the likely benefits of interventions. Current statistical models limit the data that can be used and the ecological questions that can be answered. This project expects to improve our ability to predict species distributions under changed environments given interacting species and dispersal across the landscape.Read moreRead less
