Assessment of southwest Gondwana break-up and its implications for regional hydrocarbon prospectivity must now take into account the origin of the southeast margin of the Falkland Islands as a volcanic […]
Marine geophysical data from the western Falkland Plateau show strongly lineated magnetic anomalies and a coincident linear gravity high that identify the southeastern margin of a Falkland Islands block as […]
Understanding the environmental responses of an invasive species is critical in predicting how ecosystem composition may be transformed in the future, especially under climate change. In this study, Crassostrea gigas, […]
Biological responses to climate and environmental changes in remote polar regions are of increasing interest in global change research. Terrestrial and marine polar ecosystems have suffered from impacts of both […]
Physical and chemical characteristics and solution geochemistry of major and trace elements were investigated in an area of volcanic soil colonized by mosses at Edmonson Point (central Victoria Land) during […]
During the last glacial cycle, Greenland temperature showed many rapid temperature variations, the so called Dansgaard-Oeschger (DO) events. The past atmospheric methane concentration closely followed these temperature variations, which implies […]
The ionospheric signature of a flux transfer event (FTE) seen in EISCAT radar data has been used as the basis for a modelling study using a new numerical model of […]
On the sub-Antarctic island of South Georgia the field distributions of two herbivorous perimyloid beetles Hydromedion sparsutum and Perimylops antarcticus overlap with the latter occurring at higher altitudes. An introduced […]
Euphausia superba (hereafter ‘krill’) and copepods are major zooplankton taxa in the Southern Ocean, but there is little information on how they interact. This paper investigates their coincidence across a […]
The SuperDARN radars are proving to be a very powerful experimental tool for exploring solar wind-magnetosphere-ionosphere interactions. They measure the autocorrelation function (ACF) of the transmitted signal backscattered from the […]
Levels of genetic diversity and population differentiation were examined in temporally (1990 to 1997) and geographically separated samples of the argentine short-finned squid Illex argentines using 7 microsatellite loci. Number […]
Ommastrephid squid of the genus Illex form an important trophic component of large areas of the Atlantic ocean, both as prey for fish, seabirds, whales and other cephalopods, and as […]
