  2. 1. Immersion and recreational boating-related injuries in Alaska

    Author : Diana Stark Hudson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alaska; injuries; drowning; cold water; immersion; submersion; hypothermia; survival;

    Abstract : Background: Cold water is an ever-present hazard in Alaska, and when water-related injuries occur, they often take place in remote environments, where the nearest trained emergency response teams are several hours away. Alaska’s crude drowning death rate in 2002 was 4. READ MORE

  4. 2. Genomic insights into the population history of circumpolar Arctic dogs

    Author : Tatiana Richtman Feuerborn; Anders Hansen; Love Dalen; Mikkel Holger Strander Sinding; Kerstin Liden; Matthew Collins; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Dogs; Arctic; Inuit; Migration; Siberia; Greenland; Sled Dog; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

    Abstract : The Siberian and North American Arctic have both borne witness to numerous migrations of humans and with them their dogs. This PhD thesis is based on whole genome data from 22 Siberian dogs and 72 North American Arctic dogs, in addition to 186 mitochondrial genomes Siberian and North American Arctic dogs. READ MORE

  5. 3. Biophysical controls on CO2 evasion from Arctic inland waters

    Author : Gerard Rocher-Ros; Reiner Giesler; Ryan A. Sponseller; Ann-Kristin Bergström; Paul del Giorgio; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Inland waters; carbon dioxide; organic carbon; inorganic carbon; arctic; CO2 evasion; DOC; DIC; streams; metabolism; oxygen; Limnology; limnologi;

    Abstract : CO2 evasion to the atmosphere from inland waters is a major component of the global carbon (C) cycle. Yet spatial patterns of CO2 evasion and the sources of C that fuel evasion remain poorly understood. READ MORE

  6. 4. Sociality in a solitary carnivore, the wolverine

    Author : Fredrik Dalerum; Anders Angerbjörn; Kyran Kunkel; Stanley Boutin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sociality; carnivore; behaviour; ecology; spatial organisation; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : The social organization of animal societies has important implications for several fields of biology, from managing wild populations to developing new ecological and evolutionary theory. Although much attention has been given to the formation and maintenance of societies of group living individuals, less is known about how societies of solitary individuals have been shaped and maintained.

  7. 5. On the role of migration for the distribution of arctic birds - a circumpolar perspective

    Author : Sara Henningsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bird migration; broad-scale distributions; geographic breeding range; geography of migration; non-breeding range; barriers to migration; Arctic birds; evolution of migration routes;

    Abstract : Flexibility as well as constraints to the evolution of migration routes has the possibility of affecting large-scale patterns of geographical ranges of animals both by facilitating, but sometimes restricting, accessibility to and colonization of new regions. This dissertation concerns the broad-scale effects migration has on the distributional patterns of birds in the Arctic. READ MORE
