    • Maskulinitet og trofejakt i Arktis 

      Aarekol, Lena (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
      From the late 1800s and until the protection of polar bears came into force in 1973, there were regular private hunting expeditions to the Arctic by boat, including several from Tromsø. In this article, I investigate how masculinity is manifested in specific empirical evidence: a trophy hunting expedition with the Sutton family that left from Tromsø in the summer of 1932. Using masculinity as a lens ...
    • Mass concentration of Hirnantian cephalopods from the Siljan District, Sweden; taxonomy, palaeoecology and palaeobiogeographic relationships

    • The medieval stockfish trade: a maritime perspective from northern Norway 

      Wickler, Stephen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
      Life in northern Norway has been dependent on the sea and marine resources since initial settlement following the retreating ice at least 11,500 years ago. Small islands have played a significant role for maritime communities since the Mesolithic when occupation of offshore islands reflected the maritime orientation of hunter‑gatherer settlement. Although settlement along the coast, including ...

    • Metabarcoding data reveal vertical multitaxa variation in topsoil communities during the colonization of deglaciated forelands 

      Guerrieri, Alessia; Carteron, Alexis; Bonin, Aurélie; Marta, Silvio; Ambrosini, Roberto; Caccianiga, Marco; Cantera, Isabel; Compostella, Chiara; Diolaiuti, Guglielmina; Fontaneto, Diego; Gielly, Ludovic; Gili, Fabrizio; Gobbi, Mauro; Poulenard, Jerome; Taberlet, Pierre Robert Michel; Zerboni, Andrea; Thuiller, Wilfried; Ficetola, Gentile Francesco (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-23)
      Ice-free areas are expanding worldwide due to dramatic glacier shrinkage and are undergoing rapid colonization by multiple lifeforms, thus representing key environments to study ecosystem development. It has been proposed that the colonization dynamics of deglaciated terrains is different between surface and deep soils but that the heterogeneity between communities inhabiting surface and deep soils ...
    • Metapopulation regulation acts at multiple spatial scales: Insights from a century of seabird colony census data 

      Jeglinski, Jana W.E.; Wanless, Sarah; Murray, Stuart; Barrett, Robert; Gardarsson, Arnthor; Harris, Mike P.; Dierschke, Jochen; Strøm, Hallvard; Lorentsen, Svein-Håkon; Matthiopoulos, Jason (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-27)
      Density-dependent feedback is recognized as important regulatory mechanisms of population size. Considering the spatial scales over which such feedback operates has advanced our theoretical understanding of metapopulation dynamics. Yet, metapopulation models are rarely fit to time-series data and tend to omit details of the natural history and behavior of long-lived, highly mobile species such as ...
    • MicroRNAs are deeply linked to the emergence of the complex octopus brain 

      Zolotarov, Grygoriy; Fromm, Bastian; Legnini, Ivano; Ayoub, Salah; Polese, Gianluca; Maselli, Valeria; Chabot, Peter J.; Vinther, Jakob; Styfhals, Ruth; Seuntjens, Eve; Di Cosmo, Anna; Peterson, Kevin J.; Rajewsky, Nikolaus (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-25)
      Soft-bodied cephalopods such as octopuses are exceptionally intelligent invertebrates with a highly complex nervous system that evolved independently from vertebrates. Because of elevated RNA editing in their nervous tissues, we hypothesized that RNA regulation may play a major role in the cognitive success of this group. We thus profiled messenger RNAs and small RNAs in three cephalopod species ...
    • MicroRNAs as Indicators into the Causes and Consequences of Whole-Genome Duplication Events 

      Peterson, Kevin; Beavan, Alan; Chabot, Peter J; McPeek, Mark A; Pisani, Davide; Fromm, Bastian; Simakov, Oleg (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-03)
      Whole-genome duplications (WGDs) have long been considered the causal mechanism underlying dramatic increases to morphological complexity due to the neo-functionalization of paralogs generated during these events. Nonetheless, an alternative hypothesis suggests that behind the retention of most paralogs is not neo-functionalization, but instead the degree of the inter-connectivity of the intended ...
    • Microsatellite markers for Heracleum persicum (Apiaceae) and allied taxa: application of next-generation sequencing to develop genetic resources for invasive species management

    • Million-year-old DNA sheds light on the genomic history of mammoths 

      van der Valk, Tom; Pečnerová, Patrícia; Díez-del-Molino, David; Bergström, Anders; Oppenheimer, Jonas; Hartmann, Stefanie; Xenikoudakis, Georgios; Thomas, Jessica A.; Dehasque, Marianne; Sağlıcan, Ekin; Rabia Fidan, Fatma; Barnes, Ian; Liu, Shanlin; Somel, Mehmet; Heintzman, Peter D.; Nikolskiy, Pavel; Shapiro, Beth; Skoglund, Pontus; Hofreiter, Michael; Lister, Adrian M.; Götherström, Anders; Dalén, Love (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-17)
      Temporal genomic data hold great potential for studying evolutionary processes such as speciation. However, sampling across speciation events would, in many cases, require genomic time series that stretch well back into the Early Pleistocene subepoch. Although theoretical models suggest that DNA should survive on this timescale1, the oldest genomic data recovered so far are from a horse specimen ...
    • Minimizing polymerase biases in metabarcoding 

      Nichols, Ruth V.; Vollmers, Christopher; Newsom, Lee A.; Wang, Yue; Heintzman, Peter D.; Leighton, McKenna; Green, Richard E.; Shapiro, Beth (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-24)
      DNA metabarcoding is an increasingly popular method to characterize and quantify biodiversity in environmental samples. Metabarcoding approaches simultaneously amplify a short, variable genomic region, or “barcode,” from a broad taxonomic group via the polymerase chain reaction (PCR), using universal primers that anneal to flanking conserved regions. Results of these experiments are reported as ...
    • MirGeneDB 2.1: toward a complete sampling of all major animal phyla 

      Fromm, Bastian; Høye, Eirik; Domanska, Diana; Zhong, Xiangfu; Aparicio-Puerta, Ernesto; Ovchinnikov, Vladimir; Umu, Sinan Ugur; Chabot, Peter J; Kang, Wenjing; Aslanzadeh, Morteza; Marmol-Sanchez, Emilio; Urgese, Gianvito; Johansen, Morten; Hovig, Eivind; Hackenberg, Michael; Friedländer, Marc R.; Peterson, Kevin (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-25)
      We describe an update of MirGeneDB, the manually curated microRNA gene database. Adhering to uniform and consistent criteria for microRNA annotation and nomenclature, we substantially expanded MirGeneDB with 30 additional species representing previously missing metazoan phyla such as sponges, jellyfish, rotifers and flatworms. MirGeneDB 2.1 now consists of 75 species spanning over ∼800 million ...
    • Modelled drift patterns of fish larvae link coastal morphology to seabird colony distribution 

      Sandvik, Hanno; Barrett, Robert T.; Erikstad, Kjell E; Myksvoll, Mari Skuggedal; Vikebø, Frode Bendiksen; Yoccoz, Nigel Gilles; Anker-Nilssen, Tycho; Lorentsen, Svein-Håkon; Reiertsen, Tone; Skardhamar, Jofrid; Skern-Mauritzen, Mette; Systad, Geir Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-13)
      Colonial breeding is an evolutionary puzzle, as the benefits of breeding in high densities are still not fully explained. Although the dynamics of existing colonies are increasingly understood, few studies have addressed the initial formation of colonies, and empirical tests are rare. Using a high-resolution larval drift model, we here document that the distribution of seabird colonies along the ...
    • Molecular assessment of dietary variation in neighbouring primate groups 

      Schneider, Judith; Brun, Loïc; Taberlet, Pierre Robert Michel; Fumagalli, Luca; van de Waal, Erica (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-02)
      <ol> <li>Facing rapid environmental changes and anthropogenic habitat destruction, animal behavioural plasticity becomes an adaptive potential that needs to be considered in conservation strategies along with, for example, genetic diversity. Here, we evaluate to what extent non-invasive environmental DNA (eDNA) methods may contribute to the assessment of intraspecies behavioural plasticity in terms ...
