We identified a range of foraging strategies adopted by grey-headed albatrosses Thalassarche chrysostoma rearing chicks at Bird Island, South Georgia, by simultaneously using satellite telemetry, wet/dry activity recorders and stomach […]
A Gray-headed Albatross (Thalassarche chrysostoma) was recorded traveling, in the course of a foraging trip, at a minimum average ground speed of >110 km h(-1) for similar to9 h with […]
Two principal groups of receptors orthologous with human PAC(1)R and VPAC(1)R and were identified and characterised at the genomic level in the teleost fish Fugu rubripes. An additional group orthologous […]
Net and acoustic studies of diel vertical migration (DVM) in krill often show a degree of dispersion around the mean population depth, which becomes greater during night-time. Trade-off models can […]
A recent taxonomic revision of wandering albatross elevated each of the four subspecies to species. We used mitochondrial DNA and nine microsatellite markers to study the phylogenetic relationships of three […]
Global rates and patterns of fecundity in marine epipelagic copepods were studied as a function of temperature, body weight of the female and concentration of chlorophyll a. We divided data […]
Ice is a major structuring force in marine and freshwater environments at high latitudes. Although recovery from scouring has been quantified in time, the frequency of scouring in the Antarctic […]
A species of the fungus Neozygites (Zygomycetes: Entomophthorales) is recorded from the Antarctic mite Alaskozetes antarcticus (Acarina: Oribatidales) collected off the west coast of the Antarctic peninsula. The features of […]
In January and February 2000, four ships conducted an extensive hydrographic survey of the Scotia Sea as part of the CCAMLR 2000 Survey. There were 169 CTD stations to at […]
Understanding the microstructure of ice underpins the interpretation of ice-core measurements and many ice-sheet properties. A detailed study of polar snow and ice using scanning electron microscope (SEM) and X-ray […]
There is much concern about the potential for invasive species to enter the only marine region left with no known exotics – the Southern Ocean. Attention has focused on planktonic […]
