      The typically repetitive nature of the sex-limited chromosome means that it is often excluded from or poorly covered in genome assemblies, hindering studies of evolutionary and population genomic processes in non-recombining ...
    • Evolutionary responses to a changing climate: Implications for reindeer population viability 

      Bårdsen, Bård-Jørgen (Journal article; Peer reviewed, 2017)
      If we want to understand how climate change affects long-lived organisms, we must know how individuals allocate resources between current reproduction and survival. This trade-off is affected by expected environmental ...

(Journal article; Peer reviewed, 2016)
      For over 50 years, the great tit (Parus major) has been a model species for research in evolutionary, ecological and behavioural research; in particular, learning and cognition have been intensively studied. Here, to ...
    • Exclusion of invertebrates influences saprotrophic fungal community and wood decay rate in an experimental field study 

      Jacobsen, Rannveig Margrete; Sverdrup-Thygeson, Anne; Kauserud, Håvard; Mundra, Sunil; Birkemoe, Tone (Journal article; Peer reviewed, 2018)
      1. Decomposer communities perform an essential ecosystem function by recycling nutrients. However, the effect of higher trophic levels on microbial decomposer communities and rate of decomposition is poorly understood. We ...
    • Expansion speed as a generic measure of spread for alien species 

      Sandvik, Hanno (Peer reviewed, 2019)
      The ecological impact of alien species is a function of the area colonised. Impact assessments of alien species are thus incomplete unless they take the spatial component of invasion processes into account. This paper ...
