Evolution of dispersal capacities during range expansion: size and behaviour matter in an arthropod invading the sub-Antarctic Kerguelen archipelago Open
The flexibility of movement behaviour was investigated in the non-native carabid beetle, Merizodus soledadinus , by comparing individuals from well-established populations (residents) to those at the invasion front (dispersers) in the sub-…

Is Antarctica Greening? Open
Earth's polar regions are experiencing significant climate change, impacting global oceanographic and weather patterns. Arctic “greening” is well studied, but a debate has emerged about whether similar trends are occurring in Antarctica an…

Antarctic vegetation cover greatly underestimated without ground-truthing of lichens Open
Antarctic landscapes are perceived as sparsely vegetated but support extensive lichen communities. Lichens are pioneers of bare rock, but estimates of their cover are limited. Vegetation mapping on an apparently bare Antarctic Island revea…

Status assessment of non-native terrestrial species in Antarctica Open
Antarctica has been subject to direct human activity for a little over 200 years. In recent decades, the combination of sharp increases in human activity and regional climate change, particularly around the Antarctic Peninsula and Scotia A…

Gaps and Advances in Long-Term Monitoring of Antarctic Near-Shore and Terrestrial Ecosystems Open
Environmental change due to greenhouse gas emissions is affecting ecosystems globally; in the polar regions in particular there is already significant evidence of change. The Antarctic Near-Shore and Terrestrial Observation System (ANTOS) …

New oribatid mite (Acari, Oribatida) records in the Antarctic Peninsula region Open
We report new oribatid records from the western Antarctic Peninsula region obtained during the XXIV and XXVI–XXVIII Ukrainian Antarctic expeditions. Five species (including 2 subspecies) representing five families of oribatid mites were re…

Tracing the biogeographic history of the world's most isolated insular floras Open
Inferring general biogeographic patterns in the sub‐Antarctic region has been challenging due to the disparate geological origins of its islands and archipelagos—ranging from Gondwanan fragments to uplifted seafloor and more recently forme…

DNA metabarcoding of non-fungal eukaryotic diversity in air and snow of Livingston Island, South Shetland Islands, Antarctica Open
A major natural route of dispersal to Antarctica is often assumed to be atmospheric transport, although few studies have documented this in detail. Aerial dispersal to Antarctica is very challenging as the continent is geographically remot…
