Invasive species and biosecurity

Invasive species and biosecurity research focuses on managing invasive species and enhancing biosecurity measures to protect ecosystems and biodiversity. It develops strategies to mitigate threats, control species spread and inform policies for sustainable environmental protection and agricultural resilience.

About

Species that have evolved elsewhere such as weeds, feral animals, insects and other invertebrates, diseases, fungi and parasites can have major impacts on native biodiversity.

Evolutionary changes in invasive species can increase their impact on native species and their geographic spread.
Hybridization between exotic and native species can also have significant impacts in invaded habitats.
The management of exotic pathogens can be improved by identifying resistance in the invaded host’s genome.
Native species may become invasives when they move from their current ranges as they adapt to climate change.

Projects

Uncovering the hare microbiome

The Ignition Grant Round 7 investigated the microbiome of European brown hares and rabbits in Australia, revealing differences in microbial diversity due to behaviour and diet. The study improved understanding of lagomorph pathogens and fostered collaboration between ANU and CSIRO, culminating in a published paper.

Understanding biological invasions: assessing the biosecurity threat of the pink bollworm to Northern Australia

The project investigates the genetic connectivity between Indian and Australian pink bollworm populations, using genomic sequencing to assess biosecurity threats to Australia. It aims to identify the source of Australian populations and develop genomic resources for future pest management strategies.
