Spatial and community ecology
I work on reptile spatial and community ecology, particularly in fragmented landscapes. I study how animals respond to landscape degradation and restoration, and how management actions can be optimised to produce the greatest biodiversity outcomes. I’m driven to understand how we can better measure and integrate data on animal movements to inform theory and practice.
Invasive mammalian predators, such as rats and cats, are arguably the most damaging group of alien taxa for global biodiversity, having contributed to a large number of extinctions. Understanding the ecology and impacts of these species and developing appropriate management strategies is a primary concern of conservation biologists, particularly on islands. My work on invasive predators ranges from local studies of control actions up to global analyses of impacts and contributions to policy development.

With two-thirds of the Earth’s land area considered fire-prone, fire is one of the planet’s most widespread ecosystem modifiers. Trends for increased fire frequency, size and intensity in many parts of the world mean that understanding the effects of fire on plants and animals is essential for species conservation. I have ongoing fire ecology projects in both intact and urban landscapes in western and eastern Australia.
