We quantify the relative roles of natural and anthropogenic influences on the growth rate of atmospheric CO2 and the CO2 airborne fraction, considering both interdecadal trends and interannual variability. A […]
Aim. To identify Antarctic palaeoendemic taxa and their probable glacial refugia from regional groups of endemic species records. Location. Antarctica. Methods. We compiled a list of Antarctic non-marine invertebrates from […]
The hydrothermal vent zoarcid fish Thermarces cerberus is a top predator that inhabits deep-sea hydrothermal vents on the East Pacific Rise (EPR). Bacterial chemoautotrophy at these sites supports abundant animal […]
Various types of plasma waves have profound effects on acceleration and scattering of radiation belt particles. For the purposes of radiation belt modeling it is necessary to know statistical distributions […]
Trawl activity on the continental shelf break off South Africa provides large quantities of food in the form of discards for a range of species, including non-breeding black-browed albatrosses Thalassarche […]
Cold-blooded Antarctic marine species are highly stenothermal and possibly the most temperature-sensitive group on Earth. Studies to date have produced upper lethal temperatures in the range of 4 to 10 […]
Animals can respond in three main ways to environments that change and deteriorate. They can cope with their inherent physiological flexibility, evolve or adapt to new conditions, or migrate away […]
Seven independent clone libraries were constructed to study the biodiversity of the bacterioplankton in the surface waters around Southern Thule, South Sandwich Islands, in order to identify the species present, […]
We present the results of the first ice sheet model intercomparison project for higher-order and full-Stokes ice sheet models. These models are compared and verified in a series of six […]
Compilation of existing population data through the 1999/2000 season for Northern Giant Petrels Macronectes halli and Southern Giant Petrels M. giganteus indicates that the total breeding population of Northern Giant […]
Although both the Arctic and Antarctic are subject to a similar annual cycle of solar radiation and the same increasing greenhouse gas concentrations, over the previous two decades the two […]
