Review of Environmental Monitoring by Means of Radio Waves in the Polar Regions: From Atmosphere to GeospaceNARA Subscribed
The Antarctic and Arctic regions are Earth's open windows to outer space. They provide unique opportunities for investigating the troposphere–thermosphere–ionosphere–plasmasphere system at high latitudes, which is not as well understood as the mid- and low-latitude regions mainly due to the paucity of experimental observations. In addition, different neutral and ionised atmospheric layers at high latitudes are much more variab...
The molar of a giant deer, Megaloceros giganteus (Blumenbach, 1799), was discovered in sandy deposits of the North Sea, about 10 km west of the present shoreline of the Netherlands. Compacted masticated plant remains were preserved in the molar's deep folds. A palaeoecological analysis of these plant remains shows the complete dominance of pollen from Artemisia (sage) and other Asteraceae Tubuliflorae (Compositae), indicating...
Geographic variation in growth and food conversion efficiency of juvenile Atlantic halibut related to latitudeNARA Subscribed
Higher growth capacity and food conversion efficiency was observed in populations of juvenile halibut from high Hippoglossus hippoglossus compared lower latitudes. In addition, temperature adaptation shown by the lower temperature optimum for growth in the Norwegian population (mean±S.E. 12·9±0·10 C) compared with the Icelandic and Canadian populations (14·2±0·2 and 13·9±0±30 C respectively), seems to occur. Overall the data s...
