      Szadziewski, Ryszard; Blatrix, Rumsais; Dominiak, Patrycja (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-26)
      Both sexes of Dasyhelea porczynskii Szadziewski, Blatrix et Dominiak, n. sp. collected from flowers of Aristolochia clematitis L. in southern France are described and illustrated. The new species is closely related to D. leptoclada Remm, 1967 female of which is briefly diagnosed for the first time.
    • Boats from bogs in Arctic Norway: depositional contexts and explanatory frameworks in the Late Iron Age and Mediaeval period 

      Wickler, Stephen Kent (Chapter; Bokkapittel, 2024)
      A comprehensive assessment of boat-related bog finds from the collection of the Arctic University Museum of Norway (Norges Arktiske Universitetsmuseum, NAU) materialises the entanglement of boat technology and cultural meaning in northern Norway during the Iron Age. Nineteen boat parts and related equipment made of Scots pine (Pinus sylvestris) from 17 bog locations have been documented. As the Early ...
    • A renaissance of microRNAs as taxonomic and phylogenetic markers in animals 

      Fromm, Bastian (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-21)
      Molecular markers for tracing animal sample origins and compositions are critical for applications such as parasite detection, contamination screening, and sample authentication. Among these, microRNAs have emerged as promising candidates due to their deep conservation, near-hierarchical evolution, and sta bility. I here review the suitability of microRNAs as taxonomic and also phylo genetic ...
    • Microbial community composition unaffected by mycorrhizal plant removal in sub-arctic tundra 

      Kirchhoff, Leah; Gavazov, Konstantin; Blume-Werry, Gesche; Krab, Eveline J.; Lett, Signe; Pedersen, Emily P.; Peter, Martina; Pfister, Stefanie; Väisänen, Maria; Monteux, Sylvain (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-11)
      Vegetation changes in a warming Arctic may affect plant-associated soil microbial communities with possible consequences for the biogeochemical cycling of carbon (C) and nitrogen (N). In a sub-arctic tundra heath, we factorially removed plant species with ecto- and ericoid mycorrhizal associations. After two years, we explored how mycorrhizal type-specific plant removal influences microbial ...
    • Extra-pair paternity and sperm length variation in a far northern Great Tit (Parus major) population 

      Kleven, Oddmund; Østnes, Jan Eivind; Rudolfsen, Geir; Schindler, Sonja; Schmoll, Tim (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-25)
      Extra-pair paternity is common among socially monogamous bird species and considered an important driver of post-copulatory sexual selection on ejaculate traits including sperm traits. Patterns of extra-pair paternity and sperm size both show substantial variation among populations, yet we know little about the expression of these key reproductive traits at high latitudes. Here we report patterns ...
    • Bakestones in Northern Norway: An Archaeological Witness to Medieval Foodways and Maritime Trade 

      Wickler, Stephen Kent (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-01)
      BAKESTONES ARE A 11TH-CENTURY EARLY MEDIEVAL INNOVATION associated with flatbread production that reflect a distinctive Norwegian food culture spanning some 600 years. Large scale manufacture of chlorite schist bakestones at Ølve-Hatlestrand, western Norway, was linked to further distribution in Norway from the port of Bergen. Bakestones were an important item of maritime trade transported to northern ...

      Karlsen, Stein Rune; Elvebakk, Arve; Stendardi, Laura; Høgda, Kjell Arild; Macias-Fauria, Marc (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-21)
      Svalbard, located between 76°30′N and 80°50′N, is among the regions in the world with the most rapid temperature increase. We processed a cloud-free time-series of MODIS-NDVI for Svalbard. The dataset is interpolated to daily data during the 2000–2022 period with 232 m pixel resolution. The onset of growth, with a clear phenological definition, has been mapped each year. Then the integrated NDVI ...
    • Timing and extent of primary moult in breeding Black-legged Kittiwakes Rissa tridactyla at different colonies in the north-east Atlantic 

      Furness, Robert W.; Barrett, Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-24)
      Timing of moult of the inner primaries by breeding Black-legged Kittiwakes is very similar among colonies ranging from southern England to northern Norway, but can be much later at very high-latitude colonies, such as at Svalbard, where breeding is delayed by the late spring thaw. Breeding adult Black-legged Kittiwakes almost all replaced the first and second (innermost) primary feathers on their ...

      Yu, Daqi; Ren, Yandong; Uesaka, Masahiro; Beavan, Alan; Muffato, Matthieu; Shen, Jieyu; Li, Yongxin; Sato, Iori; Wan, Wenting; Clark, James; Keating, Joseph; Carlisle, Emily; Dearden, Richard; Giles, Sam; Randle, Emma; Sansom, Robert; Feuda, Roberto; Fleming, James Frederick; Sugahara, Fumiaki; Cummins, Carla; Patricio, Mateus; Akanni, Wasiu; D'Aniello, Salvatore; Bertolucci, Christiano; Irie, Naoki; Alev, Cantas; Sheng, Guojun; de Mendoza, Alex; Maeso, Ignacio; Irimia, Manuel; Fromm, Bastian; Peterson, Kevin J; Das, Sabyasachi; Hirano, Masayuki; Rast, Jonathan P; Cooper, Max; Paps, Jordi; Pisani, Davide; Kuratani, Shigeru; Martin, Fergal J.; Wang, Wen; Donoghue, Philip C J; Zhang, Yong E.; Pascual-Anaya, Juan (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-12)
      Polyploidy or whole-genome duplication (WGD) is a major event that drastically reshapes genome architecture and is often assumed to be causally associated with organismal innovations and radiations. The 2R hypothesis suggests that two WGD events (1R and 2R) occurred during early vertebrate evolution. However, the timing of the 2R event relative to the divergence of gnathostomes ( jawed vertebrates) ...
    • Ancient DNA and osteological analyses of a unique paleo-archive reveal Early Holocene faunal expansion into the Scandinavian Arctic 

      Boilard, Aurélie; Walker, Samuel James; Lødøen, Trond; Henriksen, Mona; Takken-Beijersbergen, Liselotte M.; Star, Bastian; Robu, Marius; Tøssebo, Christine; Albrektsen, Cornelia Marie; Soleng, Yvonne; Aksnes, Sverre S; Jørgensen, Roger; Hufthammer, Anne Karin; Kolfschoten, Thijs van; Lauritzen, Stein Erik; Boessenkool, Sanne (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-29)
      Paleo-archives are essential for our understanding of species responses to climate warming, yet such archives are extremely rare in the Arctic. Here, we combine morphological analyses and bulk-bone metabarcoding to investigate a unique chronology of bone deposits sealed in the high-latitude Storsteinhola cave system (68°50′ N 16°22′ E) in Norway. This deposit dates to a period of climate warming ...

      Extensive research has focused on exploring the range of genome sizes in eukaryotes, with a particular emphasis on land plants, where significant variability has been observed. Accurate estimation of genome size is essential for various research purposes, but existing sequence-based methods have limitations, particularly for low-coverage datasets. In this study, we introduce LocoGSE, a novel ...
    • Uncovering Holocene climate fluctuations and ancient conifer populations: Insights from a high-resolution multi-proxy record from Northern Finland 

      Salonen, J. Sakari; Kuosmanen, Niina; Alsos, Inger Greve; Heintzman, Peter D.; Rijal, Dilli Prasad; Schenk, Frederik; Bogren, Freja; Luoto, Miska; Philip, Annemarie; Piilo, Sanna; Trasune, Liva; Väliranta, Minna; Helmens, Karin F. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-08)
      A series of abrupt climate events linked to circum-North Atlantic meltwater forcing have been recognised in Holocene paleoclimate data. To address the paucity of proxy records able to characterise robustly the regional impacts of these events, we retrieved a sub-centennial resolution, well-dated core sequence from Lake Kuutsjarvi, ¨ northeast Finland. By analysing a range of paleo-environmental ...
    • Physiological responses of Atlantic cod to climate change indicate that coastal ecotypes may be better adapted to tolerate ocean stressors 

      Perry, Diana; Tamarit, Elena; Sundell, Erika; Axelsson, Michael; Bergman, Sanne; Gräns, Albin; Gullström, Martin; Sturve, Joachim; Wennhage, Håkan (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-05)
      Healthy ecosystems and species have some degree of resilience to changing conditions, however as the frequency and severity of environmental changes increase, resilience may be diminished or lost. In Sweden, one example of a species with reduced resilience is the Atlantic cod (Gadus morhua). This species has been subjected to overfishing, and with additional pressures such as habitat degradation and ...
    • Rapid adaptation of cellular metabolic rate to the MicroRNA complements of mammals and its relevance to the evolution of endothermy 

      Fromm, Bastian; Sorger, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-21)
      The metabolic efficiency of mammalian cells depends on the attenuation of intrinsic translation noise by microRNAs. We devised a metric of cellular metabolic rate (cMR), rMR/Mexp optimally fit to the number of microRNA families (mirFam), that is robust to variation in mass and sensitive to body temperature (T<sub>b</sub>), consistent with the heat dissipation limit theory of Speakman and Kro´ l ...
