Biting insects in the Arctic and sub-Arctic.
THE difficulties of living in the Arctic in the winter are matters of general knowledge. It is perhaps not so well known that th~reare quite different and very acute problems during the summer season. The most serious from the medical aspect is attack by biting insects-mainly mosquitoes and blackflies. Th~ degree of this menace is difficult to imagine, unless one has experienced it personally. ...
متن کاملCystic echinococcosis in the Arctic and Sub-Arctic.
The northern biotype of Echinococcus granulosus occurs throughout the holarctic zones of tundra and taiga, from eastern Fennoscandia to the Bering Strait in Eurasia and in North America from arctic Alaska approximately to the northern border of the United States. The cycle of the cestode is complex in taiga at lower latitudes, because of the greater diversity of potential hosts. In the Arctic a...
متن کاملDynamics of recent climate change in the Arctic.
The pattern of recent surface warming observed in the Arctic exhibits both polar amplification and a strong relation with trends in the Arctic Oscillation mode of atmospheric circulation. Paleoclimate analyses indicate that Arctic surface temperatures were higher during the 20th century than during the preceding few centuries and that polar amplification is a common feature of the past. Paleocl...
متن کاملEcological dynamics across the Arctic associated with recent climate change.
At the close of the Fourth International Polar Year, we take stock of the ecological consequences of recent climate change in the Arctic, focusing on effects at population, community, and ecosystem scales. Despite the buffering effect of landscape heterogeneity, Arctic ecosystems and the trophic relationships that structure them have been severely perturbed. These rapid changes may be a bellwet...
متن کاملSea ice thickness and recent Arctic warming
The climatic impact of increased Arctic sea ice loss has received growing attention in the last years. However, little focus has been set on the role of sea ice thickness, although it strongly determines surface heat fluxes. Here ensembles of simulations using the EC-Earth atmospheric model (Integrated Forecast System) are performed and analyzed to quantify the atmospheric impacts of Arctic sea...
