Late Mesozoic bipolar bivalve faunas
Bipolar bivalve genera probably existed through the greater part of late Mesozoic (i.e. late Jurassic–late Cretaceous) time. Of the various theories put forward to account for their presence, those based […]

Since 1981, the British Antarctic Survey has flown 27 000 line kilometres over Ronne Ice Shelf, during which radio-echo ice thicknesses were recorded. An earlier map of ice thickness was […]
86Rb uptake was examined in two species of unicellular green algae, Chlamydomonas nivalis isolated from snow, and a cell wall-less mutant of the temperate freshwater Chlamydomonas reinhardii. In C. reinhardii […]
The decapods Pasiphaea scotiae (Stebbing), P. rathbunae (Stebbing), Petalidium foliaceum Bate and Acanthephyra pelagica (Risso) and the mysid Gnathophausia gigas (W.-Suhm) have been sampled from the Southern Ocean. Lipid contents […]
On occasion the third hop of an echoing magnetospheric whistler exceeds the first hop in intensity over some low range of frequencies. Case studies show that this anomalous behavior can […]
Samples of adult Alaskozetes antarcticus, an Antarctic cryptostigmatid mite, were collected in winter and summer. In 4 separate experiments, mites were maintained under relative humidities in the range: 0, 26, […]
Samples of a cryptostigmatid mite, Alaskozetes antarcticus, were collected during summer and winter on Signy Island, South Orkney Islands, in the maritime Antarctic. In four experiments, adult mites were maintained […]
