Characteristics of summer airflow over the Antarctic Peninsula in response to recent strengthening of westerly circumpolar winds
Read more of: Characteristics of summer airflow over the Antarctic Peninsula in response to recent strengthening of westerly circumpolar windsSummer 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 summertime plankton community at South Georgia (Southern Ocean): comparing the historical (1926/27) and modern (post 1995) records.
Read more of: The summertime plankton community at South Georgia (Southern Ocean): comparing the historical (1926/27) and modern (post 1995) records.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 […]

An enema method for obtaining fecal material from known individual seals on land
Read more of: An enema method for obtaining fecal material from known individual seals on landFemale 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 […]

Investigating the biases in the use of hard prey remains to identify diet composition using antarctic fur seals (Arctocephalus gazella) in captive feeding trials
Read more of: Investigating the biases in the use of hard prey remains to identify diet composition using antarctic fur seals (Arctocephalus gazella) in captive feeding trialsThe 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, […]

Application of liposome and stable isotope tracer techniques to study polyunsaturated fatty acid biosynthesis in marine zooplankton
Read more of: Application of liposome and stable isotope tracer techniques to study polyunsaturated fatty acid biosynthesis in marine zooplanktonWe investigated the ability of four species of marine zooplankton to synthesize polyunsaturated fatty acids (PUFAs) during pulse-chase tracer experiments. Liposomes containing a deuterium labelled precursor fatty acid, D5-18:3n-3, were […]

Temporal resolution of cold acclimation and de-acclimation in the Antarctic collembolan, Cryptopygus antarcticus
Read more of: Temporal resolution of cold acclimation and de-acclimation in the Antarctic collembolan, Cryptopygus antarcticusThe Antarctic collembolan, Cryptopygus antarcticus (Willem), can switch its supercooling point (SCP) between ‘winter’ and ‘summer’ modes of cold hardiness over a matter of hours. High resolution temporal scaling of […]

Scavenging in Antarctica: intense variation between sites and seasons in shallow benthic necrophagy
Read more of: Scavenging in Antarctica: intense variation between sites and seasons in shallow benthic necrophagyThe response of scavengers to a feeding cue at Adelaide Island, West Antarctic Peninsula was investigated using a baited video camera system. Fourteen experimental deployments, each lasting 72 h were […]

An energy–distance trade-off in a central-place forager, the Antarctic fur seal (Arctocephalus gazella)
Read more of: An energy–distance trade-off in a central-place forager, the Antarctic fur seal (Arctocephalus gazella)We tested the prediction that lactating fur seals (Arctocephalus gazella) at South Georgia will take prey of greater energy density with increasing distance of foraging from the colony. The study […]

Statistical relations between the probability of occurrence of Pc3-4 pulsations at high latitudes in the Antarctic regions and the solar wind and IMF parameters
Read more of: Statistical relations between the probability of occurrence of Pc3-4 pulsations at high latitudes in the Antarctic regions and the solar wind and IMF parametersGeomagnetic pulsation in the Pc3–4 bands have been studied at high Antarctic latitudes during the local summer. The statistical relation between the occurrence probability of Pc3 and Pc4 pulsations and […]

Hypoxia tolerance associated with activity reduction is a key adaptation for Laternula elliptica seasonal energetics
Read more of: Hypoxia tolerance associated with activity reduction is a key adaptation for Laternula elliptica seasonal energeticsSeasonal dormancy is a widespread mechanism for reducing energy expenditure during periods of low energy availability. Seasonal variation in activity and the cost of pumping water through the siphons were […]
