  • Evolution of female promiscuity in Passerides songbirds 
    Lifjeld, Jan T; Gohli, Jostein; Albrecht, Tomáš; Garcia-del-Rey, Eduardo; Johannessen, Lars E; Kleven, Oddmund; Marki, Petter Z; Omotoriogun, Taiwo C; Rowe, Melissah; Johnsen, Arild (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Background Female promiscuity is highly variable among birds, and particularly among songbirds. Comparative work has identified several patterns of covariation with social, sexual, ecological and life history ...
  • Female promiscuity and genetic diversity in passerine birds 
    Gohli, Jostein (Doctoral thesis / Doktoravhandling, 2014)
    This dissertation is about female promiscuity in passerine birds. By using comparative analytical approaches, I have tried to determine why there is such variation in the frequency of this behaviour. I have found that ...
  • Migration distance is positively associated with sex-linked genetic diversity in passerine birds 
    Gohli, Jostein; Lifjeld, Jan Terje; Albrecht, Tomas (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    A recent comparative analysis of passerine birds found that the frequency of extra-pair paternity was positively associated with neutral genetic diversity. It has been hypothesised that migratory species have more extra-pair ...
  • Sperm length variation among Afrotropical songbirds reflects phylogeny rather than adaptations to the tropical environment 
    Omotoriogun, Taiwo Crossby; Albrecht, Tomas; Gohli, Jostein; Horák, David; Johannessen, Lars Erik; Johnsen, Arild; Kreisinger, Jakub; Marki, Petter Zahl; Ottosson, Ulf; Rowe, Melissah; Sedlacek, Ondrej; Lifjeld, Jan Terje (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Sperm cells vary tremendously in size and shape across the animal kingdom. In songbirds (Aves: Passeri), sperm have a characteristic helical form but vary considerably in size. Most of our knowledge about sperm morphology ...
