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 […]

Radio-echo investigations of Ronne Ice Shelf
Read more of: Radio-echo investigations of Ronne Ice ShelfSince 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 […]

The effects of temperature on 86Rb uptake by two species of Chlamydomonas(Chlorophyta, Chlorophyceae)
Read more of: The effects of temperature on 86Rb uptake by two species of Chlamydomonas(Chlorophyta, Chlorophyceae)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 third hop whistler anomaly: possible evidence of df/dt-dependent wave amplification
Read more of: The third hop whistler anomaly: possible evidence of df/dt-dependent wave amplificationOn 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 […]

Effects of contrasting relative humidities on the cold tolerance of an Antarctic mite
Read more of: Effects of contrasting relative humidities on the cold tolerance of an Antarctic miteSamples 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, […]

Effects of ingestion of liquids on the cold tolerance of an Antarctic mite
Read more of: Effects of ingestion of liquids on the cold tolerance of an Antarctic miteSamples 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 […]
