Rates of disappearance of dead material of Polytrichum alpestre and Chorisodontium aciphyllum from a moss turf community and of Drepanocladus uncinatus, Calliergon sarmentosum and Cephaloziella varians from a moss carpet […]
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 […]
