First record of the invasive springtail Hypogastrura viatica occurring synanthropically in East Antarctica: First record of the invasive springtail Hypogastrura viatica: I. R. Onley et al.

Antarctica is increasingly vulnerable to invasive species, some of which have already established on the Antarctic Peninsula. The East Antarctic environment is currently recorded to be free from established non-native invertebrates. Here we report the first record of a highly invasive springtail species, Hypogastrura viatica (Collembola: Hypogastruridae), in East Antarctica in 2020. The animals were detected live in the unpacking of imported fresh produce at an Antarctic research station. This is the first record of the transfer of H. viatica to Antarctica via fresh food. Fresh produce is an uncommon pathway for H. viatica, as the species is typically associated with coastal or wet inland environments. Extensive management and surveillance were undertaken following detection, however, taxonomic identification of specimens did not occur until May 2024. We highlight the importance of mandatory reporting and prompt identification of non-native species detections to ensure appropriate responses to future incidents. A lack of species identification may lead to more serious consequences for the environment and ecosystems of East Antarctica. [ABSTRACT FROM AUTHOR]
