(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    In recent years, the field of sexual selection has exploded, with advances in theoretical and empirical research complementing each other in exciting ways. This perspective piece is the product of a “stock-taking” workshop ...

    Interspecific competition is thought to play a key role in determining the coexistence of closely related species within adaptive radiations. Competition for ecological resources can lead to different outcomes from character ...

  • Gopalakrishnan Saroja, Seethapathy; Kaliamoorthy, Ravikumar; Paulsen, Berit Smestad; de Boer, Hugo; Wangensteen, Helle (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Ethnopharmacological relevance: More than 15,000 angiosperm species are dioecious, i.e., having distinct male and female individual plants. The allocation of resources between male and female plants is different, and also ...

    The extensive spatial and temporal coverage of many citizen science datasets (CSD) makes them appealing for use in species distribution modeling and forecasting. However, a frequent limitation is the inability to validate ...
  • Støstad, Hanna Nyborg (Doctoral thesis / Doktoravhandling, 2018)
