    Epigenetikk er læren om arvelige mekanismer som regulerer aktiviteten til genene i ulike celler og vev som ikke involverer en endring i selve DNA-sekvensen. Om gener er skrudd av eller på er bestemt av epigenetiske merkelapper ...
  • Mysterud, Atle; Rolandsen, Christer Moe (Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)
    1. Fencing is a contentious issue due to its impact on conservation. The Danish government aims to establish a 70 km fence towards the border of Germany and the agricultural ministry of Bulgaria erected 133 km fences along ...

    Cryptic species could represent a substantial fraction of biodiversity. However, inconsistent definitions and taxonomic treatment of cryptic species prevent informed estimates of their contribution to biodiversity and ...
  • Nyrud, Martine Haukland (Master thesis / Masteroppgave, 2020)
    Background and aims – The species delimitations within the prostrate species with condensed inflorescence in Chlorophytum are ambiguous and the taxonomic rank of several of the species involved are disputed. This study ...
  • Roney, Nancy; Oomen, Rebekah Alice; Knutsen, Halvor; Olsen, Esben Moland; Hutchings, Jeffrey (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Successful resource‐management and conservation outcomes ideally depend on matching the spatial scales of population demography, local adaptation, and threat mitigation. For marine fish with high dispersal capabilities, ...
  • Rogers, Lauren; Storvik, Geir Olve; Knutsen, Halvor; Olsen, Esben Moland; Stenseth, Nils Christian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    1. Identifying the spatial scale of population structuring is critical for the conservation of natural populations and for drawing accurate ecological inferences. However, population studies often use spatially aggregated ...
  • Ellingsrud, Ada Johanne; Solbrå, Andreas Våvang; Einevoll, Gaute; Halnes, Geir; Rognes, Marie Elisabeth (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Mathematical models for excitable cells are commonly based on cable theory, which considers a homogenized domain and spatially constant ionic concentrations. Although such models provide valuable insight, the effect of ...
  • Mobarhan, Milad; Halnes, Geir; Martínez-Cañada, Pablo; Hafting, Torkel; Fyhn, Marianne; Einevoll, Gaute (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Visually evoked signals in the retina pass through the dorsal geniculate nucleus (dLGN) on the way to the visual cortex. This is however not a simple feedforward flow of information: there is a significant feedback from ...
  • Brosset, Pablo; Durant, Joel Marcel; Van Beveren, Elisabeth; Plourde, Stéphane (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Climate variability, fishing and predation are the main factors affecting fish population dynamics. In this study, the drivers of population growth variability were investigated for 7 fish stocks (2 cod, 4 herring and 1 ...
  • Mekonnen, Addisu; Fashing, Peter; Sargis, Eric J.; Venkataraman, Vivek V.; Bekele, Afework; Hernandez-Aguilar, Raquel Adriana; Rueness, Eli Knispel; Stenseth, Nils Christian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Studies of the effects of habitat fragmentation and degradation on primate positional behavior, strata use, and substrate utilization offer valuable insights into the behavioral and ecological flexibility of primates whose ...
  • Christiansen, Svenja; Klevjer, Thor Aleksander; Røstad, Anders; Aksnes, Dag Lorents; Kaartvedt, Stein (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Variability of mesopelagic scattering layers is often attributed to environmental conditions or multi-species layer composition. Yet, little is known about variation in behaviour among the individuals forming scattering ...
  • Skarshaug, Renate (Master thesis / Masteroppgave, 2017)
  • Gebremichael, Gelaye; Alemu, Diress Tsegaye; Bunnefeld, Nils; Zinner, Dietmar; Atickem, Anagaw Meshesha (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Shade coffee farming has been promoted as a means of combining sustainable coffee production and biodiversity conservation. Supporting this idea, similar levels of diversity and abundance of birds have been found in shade ...
  • Sherstha, Mani; Garcia, Jair E.; Chua, Justin H. J.; Howard, Scarlet R.; Tscheulin, Thomas; Dorin, Alain; Nielsen, Anders; Dyer, Adrian G. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    To monitor and quantify the changes in pollinator communities over time, it is important to have robust survey techniques of insect populations. Pan traps allow for the assessment of the relative insect abundance in an ...
  • Mobekk, Hilde; Hessen, Dag Olav; Fagerstrøm, Asle; Jacobsen, Hanne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    These days many gyms and fitness centers are closed to reduce transmission of the SARS-CoV-2 virus in society. The gym is an environment rich in microorganisms, and careful hygiene is a necessity to keep infections at bay. ...
