Introduced species infiltrate recent stages of succession after glacial retreat on sub-Antarctic South Georgia.

Biological invasions are one of the main drivers of global biodiversity decline. At the same time, glacial retreat induced by climate warming is occurring at an alarming rate across the globe, threatening unique taxa and ecosystems. However, we know little about how introduced species contribute to the dynamics of colonisation...

First record of the introduced ladybird beetle, Coccinella undecimpunctata Linnaeus (1758), on South Georgia (sub-Antarctic).

Biological invasions represent a growing threat to islands and their biodiversity across the world. The isolated sub‐Antarctic island of South Georgia in the South Atlantic Ocean is a highly protected area that relies on effective biosecurity including prevention, surveillance and eradication to limit the risk of biological invasions. Based on...
