This project aims to improve knowledge about the central role that animal social behaviour plays in the spread of emerging infectious fungal diseases in nature. Applying approaches from behavioural ecology, network modelling and quantitative genetics, and utilising rare empirical pre- and post-infection data, the project expects to generate new understandings about how fungal diseases spread through animal populations, how animal social behaviour influences disease transmission, and how disease-status affects animal social behaviour. This project should have international impact, and advance current knowledge about disease dynamics. Applied outcomes should inform much-needed control strategies to benefit wildlife and preserve biodiversity. Read moreRead less
Integrating evolution and plasticity into predictions of population persistence in a changing climate: adaptation or extinction? To effectively manage biodiversity at a time of rapid environmental change, Australia needs accurate predictions of how human alterations to climate and habitat will affect species. This project integrates evolution and spatial ecology to develop new tools for predicting and understanding how species will respond to environmental change.
What drives novel community formation? Mechanisms of resilience against invasion and native species persistence under land use change. Environmental change is driving the creation of novel communities, stable mixes of native and exotic species. These communities are inevitable outcomes of human-induced environmental changes, yet why and how they form is still poorly understood. As these communities maintain high levels of native biodiversity, they are of great conservation value. Using Western A ....What drives novel community formation? Mechanisms of resilience against invasion and native species persistence under land use change. Environmental change is driving the creation of novel communities, stable mixes of native and exotic species. These communities are inevitable outcomes of human-induced environmental changes, yet why and how they form is still poorly understood. As these communities maintain high levels of native biodiversity, they are of great conservation value. Using Western Australia wildflower communities, This project aims to provide the first experimental tests of which environmental and biotic factors drive novel community formation, native species persistence and resilience to invasion. This will be important for developing realistic conservation plans in many ecosystems globally, and more specifically in Western Australia's biodiversity hotspot.Read moreRead less
The genetic link between local adaptation and speciation. Darwin believed that natural selection drove the origin of new species, or speciation. However, research on speciation during the 20th century shifted focus from studying adaptation within a population to examining the causes of reproductive isolation (lack of interbreeding) between populations. This Project aims to unify our understanding of adaptation and reproductive isolation by examining their shared heredity. Using an established sy ....The genetic link between local adaptation and speciation. Darwin believed that natural selection drove the origin of new species, or speciation. However, research on speciation during the 20th century shifted focus from studying adaptation within a population to examining the causes of reproductive isolation (lack of interbreeding) between populations. This Project aims to unify our understanding of adaptation and reproductive isolation by examining their shared heredity. Using an established system in natural conditions, this project will generate new knowledge on the genetic processes driving speciation. This interdisciplinary research will clarify how biodiversity originates with implications for crops, conservation biology and species responses to environmental change.Read moreRead less
Sex and bottlenecks: understanding the evolutionary dynamics of bacterial adaptation. Bacteria can rapidly adapt to changing environments, often with devastating consequences for humans. However, this adaptive evolution is often limited by strong reductions in population size, in particular during transmission from one host to another. This project aims to investigate whether recombination in bacteria can overcome the limits that such bottlenecks impose on the rate of adaptation. To this end, it ....Sex and bottlenecks: understanding the evolutionary dynamics of bacterial adaptation. Bacteria can rapidly adapt to changing environments, often with devastating consequences for humans. However, this adaptive evolution is often limited by strong reductions in population size, in particular during transmission from one host to another. This project aims to investigate whether recombination in bacteria can overcome the limits that such bottlenecks impose on the rate of adaptation. To this end, it will construct mathematical models and complement them with evolution experiments in bacterial populations. Results from this research aim to generate fundamental insights into the role of recombination in bacterial evolution and will provide guidance for developing management strategies for bacterial pathogens.Read moreRead less
Determining how plant populations will respond to climate change. It is widely predicted that global climate change will result in extinctions, invasions and disruption of the ecosystem services plants provide. In order to manage or adapt to these consequences of changing climate we need accurate forecasts of where suitable conditions for sustainable plant populations will occur. This project will enable better forecasts of where and how fast plant populations will expand or contract in response ....Determining how plant populations will respond to climate change. It is widely predicted that global climate change will result in extinctions, invasions and disruption of the ecosystem services plants provide. In order to manage or adapt to these consequences of changing climate we need accurate forecasts of where suitable conditions for sustainable plant populations will occur. This project will enable better forecasts of where and how fast plant populations will expand or contract in response to climate change. New population modelling methods which integrate plant survival, growth and reproduction along environmental gradients, together with field studies at unprecedented national and international scales, will enable better forecasts of future locations for plant dependent industries and environmental services.Read moreRead less
Discovering sex determining genes in a reptile with genetic and environmental sex determination. Reptile sex determination is particularly fascinating because it is triggered either by genes on sex chromosomes or by the nest temperature. This project will identify and characterise candidate sex determining genes in a model reptile to understand how genes control sexual differentiation and how they interact with temperature.
