    • An integrated population model for a long-lived ungulate: more efficient data use with Bayesian methods 

      Lee, Aline Magdalena; Bjørkvoll, Eirin Marie; Hansen, Brage Bremset; Albon, Steve D.; Stien, Audun; Sæther, Bernt-Erik; Engen, Steinar; Veiberg, Vebjørn; Loe, Leif Egil; Grøtan, Vidar (Journal article, 2015)
      We develop an integrated population model for Svalbard reindeer Rangifer tarandus platyrhynchus, and demonstrate how this type of model can be used to extract more information from the data and separate different sources ...

    • Bryophytes dominate plant regulation of soil microclimate in alpine grasslands 

      Jaroszynska, Francesca Orinda Holl; Althuizen, Inge; Halbritter Rechsteiner, Aud Helen; Klanderud, Kari; Lee, Hanna; Telford, Richard James; Vandvik, Vigdis (Peer reviewed; Journal article, 2023)
      Soil temperature and moisture are important regulators of a broad range of biotic and abiotic processes in terrestrial ecosystems. Vegetation can, in turn, play a role in regulating soil microclimate, which creates potential ...

    • Demographic influences of translocated individuals on a resident population of house sparrows 

      Ranke, Peter Sjolte; Skjelseth, Sigrun; Pärn, Henrik; Herfindal, Ivar; Borg Pedersen, Åsa Alexandra; Stokke, Bård Gunnar; Kvalnes, Thomas; Ringsby, Thor Harald; Sæther, Bernt-Erik; Jensen, Henrik (Journal article; Peer reviewed, 2017)
      Translocation of individuals from source populations to augment small populations facing risk of extinction is an important conservation tool. Here we examine sex-specific differences between resident and translocated house ...

    • Determinants of age at first reproduction and lifetime breeding success revealed by full paternity assignment in a male ungulate 

      Markussen, Stine Svalheim; Herfindal, Ivar; Loison, Anne; Solberg, Erling Johan; Haanes, Hallvard; Røed, Knut; Heim, Morten; Sæther, Bernt-Erik (Journal article; Peer reviewed, 2018)
      Age at first reproduction is an important determinant of individual variation in reproductive success in ungulates, but few studies have examined its relationship with later fitness‐related traits in males. We used a ...

    • Litter type and termites regulate root decomposition across contrasting savanna land-uses 

      Smith, Stuart; Speed, James David Mervyn; Bukombe, John; Hassan, Shombe Ntaraluka; Lyamuya, Richard Daniel; Mtweve, Philipo Jacob; Sundsdal, Anders; Graae, Bente Jessen (Journal article; Peer reviewed, 2018)
      Decomposition is a vital ecosystem process, increasingly modified by human activity. Theoretical frameworks and empirical studies that aim to understand the interplay between human land-use, macro-fauna and decomposition ...

    • On fitness and partial migration in a large herbivore – migratory moose have higher reproductive performance than residents 

      Rolandsen, Christer Moe; Solberg, Erling Johan; Sæther, Bernt-Erik; Van Moorter, Bram; Herfindal, Ivar; Bjørneraas, Kari (Journal article; Peer reviewed, 2016)
      Partially migratory populations comprise both resident and migratory individuals. Th ese tactics may coexist if their demographic contribution to future generations (i.e. fitness) are equal or vary temporally with environmental ...

    • Within-colony segregation of foraging areas: from patterns to processes 

      Morinay, Jennifer; Riotte-Lambert, Louise; Aarts, Geert; De Pascalis, Federico; Imperio, Simona; Morganti, Michelangelo; Catoni, Carlo; Assandri, Giacomo; Ramellini, Samuele; Rubolini, Diego; Cecere, Jacopo G (Journal article, 2023-02-27)
      Spatial segregation of foraging areas among conspecifics breeding in neighbouring colonies has been observed in several colonial vertebrates and is assumed to originate from competition and information use. Segregation ...
