Australia’s biodiversity crisis continues to deepen, with predation by non-native predators such as cats and foxes strongly contributing to native fauna declines and extinctions. Yet loss of habitat to invasive weeds and land-clearing also pose important threats. Experience with such threats over eco-evolutionary timescales can often explain how well a native species will respond to novel pressures.
In this talk I will review my research on prey naivety towards non-native predators in Australia, place that body of work in a global context, and show how it fits into a recent overarching synthesis of predator-prey recognition theory.
I will then briefly explore more recent work on the role of experience and chemical cues in herbivore foraging choices within invaded vegetation communities, before describing a future research agenda combining these strands into novel approaches to stem faunal extinctions.
I am a Macquarie University Research Fellow using behavioural, chemical, and microbial ecology to address conservation problems arising from introduced species and anthropogenic disturbance.
I focus on how non-native species disrupt native predator-prey and plant-herbivore interactions, particularly through mismatched cue detection and discrimination systems. This has extended to recent explorations of the interface between odour ecology and the mammalian microbiome.
Closer to home, I currently lead a range of projects on the behavioural ecology, genetics, and virome of Sydney’s urban foxes.
