Energy requirements of antarctic sledge dogs
1. Eighteen male sledge dogs were weighed immediately on removal from their sheltered winter quarters at Halley Bay, Antarctica (75° 31′s, 26° 42′W) and weekly thereafter for 14 weeks. The […]

1. Eighteen male sledge dogs were weighed immediately on removal from their sheltered winter quarters at Halley Bay, Antarctica (75° 31′s, 26° 42′W) and weekly thereafter for 14 weeks. The […]
1. Previous measurements of energy intake on sledging journeys in Antarctica have given a mean intake of 14.2 MJ (Acheson, 1974; Campbell, 1975), markedly lower than values reported earlier (see […]
1. The biomasses of free-living soil nematodes from a moss turf and a moss carpet, two contrasting bryophyte ecosystems in the maritime Antarctic, are analysed and compared with other tundra […]
Signals from very low frequency (VLF) transmitters can leak from the Earth‐ionosphere wave guide into the inner magnetosphere, where they propagate in the whistler mode and contribute to electron dynamics […]
Signals from man‐made Very Low Frequency (VLF) transmitters, used for communications with submarines, can leak into space and contribute to the dynamics of energetic electrons in the inner radiation belt […]
Variations in the rate of moulting and of faecal pellet production by Cryptopygus antarcticus (Willem), collected from Signy Island in the maritime Antarctic, were measured over temperatures of 0° to […]
