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

In October 2014, a project began in SE Arnhem Land to document biodiversity using Indigenous and Western knowledge. The Yugul Mangi Rangers collaborate with ecologists to input data into the Atlas of Living Australia, aiming to enhance biodiversity understanding and create employment pathways for the community.

The project investigates if adaptation in invasive plant species affects fire regimes. Researchers from ANU and CSIRO study traits promoting fire tolerance or flammability, using genomics and spatial genetic analyses. This work could influence policy on climate change adaptation and ecosystem management in Australia.

The Solomon Lab's project aims to identify microbes from major weed species to develop novel biocontrol methods. Students will work with ANU and CSIRO, supported by a $5,000 stipend. This research could improve agricultural productivity by targeting pathogens and weeds affecting crops and pastures.

The Ignition Grant Round 3 project aims to enhance genomic resources for Helicoverpa species, focusing on pest and non-pest comparisons. By using advanced sequencing techniques on museum specimens, the study seeks to uncover evolutionary traits, inform conservation strategies, and aid in biosecurity planning for these agricultural pests.

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.

This CBA-supported Honours/Masters project, now awarded, focuses on the role of European brown hares in Australia regarding lagomorph microbial diversity. Using Nanopore sequencing, it aims to understand hare-rabbit pathogen dynamics. It offered a $5,000 stipend and collaboration with ANU and CSIRO.
