Climatic changes can induce geographic expansion and altitudinal shifts in the distribution of invasive species by offering more thermally suitable habitats. At the remote sub-Antarctic Kerguelen Islands, the predatory insect […]
The current method for averaging model ensembles, which is to calculate a multi model mean, assumes model independence and equal model skill. Sharing of model components amongst families of models […]
Gravity drainage is the dominant process redistributing solutes in growing sea ice. Modelling gravity drainage is therefore necessary to predict physical and biogeochemical variables in sea ice. We evaluate seven […]
Atmospheric 8‐ and 6‐hr tides are observed for the first time in the zonal and meridional winds at ~82–97 km altitudes simultaneously at Tierra del Fuego (TDF; 53.7°S, 67.7°W), King […]
Geomagnetic indices are routinely used to characterize space weather event intensity. The DST index is well resolved, but is only available over 5 solar cycles. The aa index extends over […]
Antarctic shallow coastal marine communities were long thought to be isolated from their nearest neighbours by hundreds of kilometres of deep ocean and the Antarctic Circumpolar Current. The discovery of […]
The presence of flowering plants within the Antarctic botanical zone (as defined by Greene 1964 a) has been known for nearly 150 years. The first to be discovered was a […]
Signy Island (lat. 60° 43′ S, long. 45° 38′ W) is one of the southernmost and smaller members of the South Orkney Islands, which lie in the South Atlantic Ocean […]
The aim of the present paper is to summarize the broad scope of this Discussion and to attempt to draw certain final generalizations about the Antarctic as a biological zone. […]
