    Location Notes:
    Ecosystem change: Despite sporadic work on the impacts of house mice (Mus musculus) on Macquarie Island, little is known of their direct ecological impact. Research on their typical food sources shows that they feed on invertebrates plus some plants and seeds. They are distributed throughout the island including the upland fellfield and grassland communities.
    Despite video evidence of mice eating albatross chicks on (sub-Antarctic) Gough Island, this behaviour has not been recorded on Macquarie Island. However mice are not a part of a natural ecological system on Macquarie Island and are likely to mainly effect invertebrate populations and plant associations.
