The Antarctic intertidal zone is one of the world’s most extreme marine environments. As well as having a typically high annual temperature variation (~ 30 °C), it is affected by […]
The human-assisted establishment of two non-native predatory carabid beetles (Merizodus soledadinus (Guerin-M,n,ville), Trechisibus antarcticus (Dejean)) on the sub-Antarctic island of South Georgia occurred 30-50 years ago, but the distribution of […]
It has long been maintained that the majority of terrestrial Antarctic species are relatively recent, post last glacial maximum, arrivals with perhaps a few microbial or protozoan taxa being substantially […]
The process of organismal freezing in the Antarctic limpet, Nacelle concinna, is complicated by molluscan biology. Internal ice formation is, in particular, mediated by two factors: (a) the provision of […]
This study explores the manner in which the plasmapause is responsible for dictating which magnetospheric source regions of ELF/VLF chorus are able to propagate to and be received by midlatitude […]
Patagonian toothfish (Dissostichus eleginoides) is a large notothenioid fish that supports valuable fisheries throughout the Southern Ocean. D. eleginoides are found on the southern shelves and slopes of South America […]
The field of Genomics has essentially been fuelled by medical research with developments in human gene therapy, such as the Human Genome Project. This major international undertaking resulted in a […]
Coupling between the Rice Convection Model and Ring Current-Atmospheric Interactions Model codes is used to simulate the dynamical evolution of ring current ion phase space density and the thermal electron […]
In recent years, the international “Southern Elephant seals as Oceanographic Samplers” (SEaOS) project has deployed miniaturized conductivity-temperature-depth satellite-relayed data loggers (CTD-SRDL) on elephant seals 1) to study their winter foraging […]
Miniature electronic data recorders and transmitters have revolutionized the way we study animals over the past decades, particularly marine animals at sea. But, very recently, animal-borne instruments have also been […]
Aim At the height of glaciations such as the Last Glacial Maximum (LGM), benthic life on polar continental shelves was bulldozed off nearly all of the Antarctic shelf by grounded […]
Ice-core records of climate from Greenland and Antarctica show asynchronous temperature variations on millennial timescales during the last glacial period(1). The warming during the transition from glacial to interglacial conditions […]
