2. Determination of representative height distributions of the electron concentration in the ionosphere

   Median height distributions of electron concentration may be determined from ionograms by means of the composite ionogram technique of Wright, or by inserting tabulated parameters in the idealized model of […]

3. Signatures of the evolution of parthenogenesis and cryptobiosis in the genomes of panagrolaimid nematodes

   Most animal species reproduce sexually and fully parthenogenetic lineages are usually short lived in evolution. Still, parthenogenesis may be advantageous as it avoids the cost of sex and permits colonisation […]

4. Solar-cycle modifications of the effects of thermospheric winds on the height of the F2-layer over Antarctica

   Results of analysis of the diurnal variations of hmF2 for Argentine Islands (65°15’S, 64°16’W) and Halley Bay (75°30’S, 26°40’W) are presented. It is shown that, for summer months, the diurnal […]

5. A further comparison of glacier velocities measured by radio-echo and survey methods

   A comparison has been mager between ice velocities that were measured by the radio-echo technique and by a survey method on the Devon Island ice cap, Arctic Canada (lat. 75° […]

8. Thermodynamics of the interaction between ice shelves and the sea

   An ice shelf is a floating ice sheet, attached to land where ice is grounded along the coastline. Nourished both by surface snow accumulation and by glaciers and ice sheets […]

11. Growth and population dynamics of the moss Polytrichum alpestre. in the Maritime Antarctip. Strategies of growth and population dynamics of tundra Plants 2

    The pattern of growth of Polytrichum alpestre Hoppe, a common moss in the maritime Antarctic, is described. It may form extensive communities, sometimes growing with another moss, Chorisodontium aciphyllum (Hook. […]

12. The origin of stomach oil in marine birds: Analyses of the stomach oil from six species of subantarctic procellariiform birds

    The stomach oil produced by many marine birds of the order Procellariiformes is an important aspect of their breeding ecology. Fifty-seven samples of stomach oil from six species of subantarctic […]
