Invasive species and biosecurity
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.
