1. 1. Genomic insights into the population history of circumpolar Arctic dogs

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

   Sammanfattning : 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. LÄS MER

3. 2. High-resolution mapping and spatial variability of soil organic carbon storage in permafrost environments

   Författare :Matthias Benjamin Siewert; Gustaf Hugelius; Peter Kuhry; Iain Hartley; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon; soil organic carbon; permafrost; soil; land cover classification; digital soil mapping; machine-learning; ecosystem; mapping; landscape studies; Siberia; Arctic; Physical Geography; naturgeografi;

   Sammanfattning : Large amounts of carbon are stored in soils of the northern circumpolar permafrost region. High-resolution mapping of this soil organic carbon (SOC) is important to better understand and predict local to global scale carbon dynamics. LÄS MER

4. 3. Palaeodiet and Infant Feeding in Coastal Arctic Settlements : Insights from stable isotope analysis of bone and dentine collagen and amino acids

   Författare :Alison Harris; Gunilla Eriksson; Kerstin Lidén; Michelle Alexander; Tamsin O'Connell; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Arctic; palaeodiet; Inuit; Yup’ik; infant feeding; domestic dogs; amino acids; collagen; stable isotopes; maintenance activities; gender; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

   Sammanfattning : This dissertation investigates the day-to-day activities that sustained human societies in the arctic and subarctic environments of North America and Siberia over the past 1500 years. Maintenance activities, such as food preparation, childcare, and the care of domestic animals, are commonly inflected by social identity and can provide insight into the experience of gender among archaeological and historical populations.

5. 4. Chemical composition of Arctic aerosols and their link to clouds

   Författare :Yvette Gramlich; Claudia Mohr; Paul Zieger; Ilona Riipinen; Ulrich Pöschl; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; aerosols; cloud residuals; mass spectrometry; biomass burning; Environmental Sciences; miljövetenskap;

   Sammanfattning : The Arctic is a place particularly vulnerable to climate change, warming at an accelerated rate compared to the rest of the Earth. In this remote environment, the atmosphere, the ocean, the ice, and the land are all interlinked and are shaping a very complex system. LÄS MER

7. 5. Investigating the impacts of Late Pleistocene climate change on Arctic mammals using palaeogenomics

   Författare :Edana Lord; Love Dalén; Mirte Bosse; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palaeogenomics; Arctic; Late Pleistocene; past climate; collared lemming; woolly rhinoceros; Norwegian lemming; muskox; demography; population structure; speciation; adaptation; genome erosion; Systematic Zoology; zoologisk systematik och evolutionsforskning;

   Sammanfattning : The climatic fluctuations of the Late Pleistocene likely had a large impact on the evolutionary history of Arctic species. Palaeogenomics is a useful tool to shed light on how past populations responded to these climatic shifts and the associated ice sheet dynamics and sea level change. LÄS MER
