Amino acids constitute one of the largest inputs of organic nitrogen (N) to most polar soils and have been hypothesized to be important in regulating vegetational succession and productivity in […]
Similarity analysis is used to identify the control parameter RA for the subset of avalanching systems that can exhibit self-organized criticality SOC. This parameter expresses the ratio of driving to […]
The consequences of warming for Antarctic long-lived organisms depend on their ability to survive changing patterns of climate and environmental variation. Among birds and mammals of different Antarctic regions, including […]
We review the distributions and functions of mycorrhizas and dark septate root endophytes in polar regions. Arbuscular mycorrhizas (AM) are present in the Arctic and Antarctic to 82 ºN and […]
In this paper we determine the probability of substorm onset as a function of open magnetic flux in the magnetosphere by comparing the occurrence distribution of open flux observed at […]
We present a detailed analysis of the spatial structure of the ionospheric plasma velocity in the nightside F-region ionosphere, poleward of the open-closed magnetic field line boundary (OCB), i.e. in […]
The MIST (magnetosphere, ionosphere and solar–terrestrial physics) group of the RAS has been reinvigorated with a more formal structure, including a council, and a more thematic approach to the regular […]
The oceanic southern margin of Gondwana, from southern South America through South Africa, West Antarctica, New Zealand (in its pre break-up position), and Victoria Land to Eastern Australia is one […]
Summer near-surface temperatures over the northeast coast of the Antarctic Peninsula have increased by more than 2°C over the past 40 years, a temperature increase 3 times greater than that […]
The earliest comprehensive plankton sampling programme in the Southern Ocean was 32 undertaken during the early part of last century by Discovery Investigations to gain a 33 greater scientific understanding […]
Female Antarctic fur seals returning ashore after foraging trips were restrained, and fecal material was obtained by introducing approximately one litre of warm water into the animal’s colon via the […]
The analysis of pinniped scats has been used to quantify their diet, using prey remains to identify species and to estimate the numbers and sizes of prey consumed. There are, […]
