Ancient Biological Invasions and Island Ecosystems: Tracking Translocations of Wild Plants and Animals

Biological invasions are one of the great threats to earth’s ecosystems and biodiversity in the anthropocene. however, species introductions and invasions extend deep into the human past, with the translocation of both wild and domestic species around the world. here, we review the human translocation of wild plants and animals to the world’s islands. we focus on establishing criteria used to differentiate natural from human-assisted dispersals and the differences between non-native and invasive species. our study demonstrates that, along with a suite of domesticates, ancient people transported numerous wild plants and animals to islands and helped shape ecosystems in ways that have important ramifications for modern conservation, restoration, and management.
