1. 1. Miljökemikaliers påverkan på isbjörnars (Ursus maritimus) reproduktion och hur dessa kemikalier når djuren

   Kandidat-uppsats, SLU/Dept. of Anatomy, Physiology and Biochemistry

   Författare :Jessica Isaksson; [2015]
   Nyckelord :isbjörn; slädhund; reproduktion; miljökemikalier; spridning; könsmognad; könsorgan; missbildningar; polyklorerade bifenyler; organiska klorföreningar; polar bear; sledge dog; reproduction; environmental chemicals; distribution; sexual maturation; genitals; malformations; polychlorinated biphenyls; organochlorine compounds;

   Sammanfattning : Environmental chemicals are transported to the Arctic through the air and oceans, once within the Arctic they spread through rivers, lakes and other watercourses. Polar bears and sledge dogs in-gest high concentrations of environmental chemicals since many of the chemicals are fat-soluble and their diet mainly consists of marine mammals. LÄS MER

3. 2. Modelling vegetation dynamics and carbon fluxes in a high Arctic mire

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Laura Reinelt; [2015]
   Nyckelord :methane dynamics; biogeochemical cycling; vegetation dynamics; ecosystem modelling; LPJ-GUESS; geography; physical geography; high Arctic wetland; Zackenberg; Earth and Environmental Sciences;

   Sammanfattning : High Arctic wetlands are an important component of the global climate system. Nevertheless estimations of their expected response to climate change and associated climate-feedbacks have large uncertainties. Improving models for vegetation and carbon dynamics of ecosystems is an important step towards making predictions more accurate. LÄS MER
