• Animal models with group-specific additive genetic variances: extending genetic group models 

      Muff, Stefanie; Niskanen, Alina Katariina; Saatoglu, Dilan; Keller, Lukas; Jensen, Henrik (Journal article; Peer reviewed, 2019)
      Background The animal model is a key tool in quantitative genetics and has been used extensively to estimate fundamental parameters, such as additive genetic variance or heritability. An implicit assumption of animal ...
    • Dispersal in a house sparrow metapopulation: An integrative case study of genetic assignment calibrated with ecological data and pedigree information 

      Saatoglu, Fikriye Dilan; Niskanen, Alina Katariina; Kuismin, Markku; Ranke, Peter Sjolte; Hagen, Ingerid Julie; Araya-Ajoy, Yimen; Kvalnes, Thomas; Pärn, Henrik; Rønning, Bernt; Ringsby, Thor Harald; Sæther, Bernt-Erik; Husby, Arild; Sillanpää, Mikko J.; Jensen, Henrik (Peer reviewed; Journal article, 2021)
      Dispersal has a crucial role determining ecoevolutionary dynamics through both gene flow and population size regulation. However, to study dispersal and its consequences, one must distinguish immigrants from residents. ...
    • Genetic assignment of individuals to source populations using network estimation tools 

      Kuismin, Markku; Saatoglu, Dilan; Niskanen, Alina Katariina; Jensen, Henrik; Sillanpää, Mikko J. (Peer reviewed; Journal article, 2019)
      Dispersal, the movement of individuals between populations, is crucial in many ecological and genetic processes. However, direct identification of dispersing individuals is difficult or impossible in natural populations. ...
    • Inferences of genetic architecture of bill morphology in house sparrow using a high-density SNP array point to a polygenic basis 

      Lundregan, Sarah; Hagen, Ingerid Julie; Gohli, Jostein; Niskanen, Alina Katariina; Kemppainen, Petri; Ringsby, Thor Harald; Kvalnes, Thomas; Pärn, Henrik; Rønning, Bernt; Holand, Håkon; Ranke, Peter Sjolte; Båtnes, Anna Solvang; Selvik, Linn-Karina M.; Lien, Sigbjørn; Sæther, Bernt-Erik; Husby, Arild; Jensen, Henrik (Journal article; Peer reviewed, 2018)
      Understanding the genetic architecture of quantitative traits can provide insights into the mechanisms driving phenotypic evolution. Bill morphology is an ecologically important and phenotypically variable trait, which is ...
    • Variation in generation time reveals density regulation as an important driver of pace of life in a bird metapopulation 

      Araya-Ajoy, Yimen; Niskanen, Alina Katariina; Froy, Hannah; Ranke, Peter Sjolte; Kvalnes, Thomas; Rønning, Bernt; Pepke, Michael Le; Jensen, Henrik; Ringsby, Thor Harald; Sæther, Bernt-Erik; Wright, Jonathan (Journal article; Peer reviewed, 2021)
      Generation time determines the pace of key demographic and evolutionary processes. Quantified as the weighted mean age at reproduction, it can be studied as a life-history trait that varies within and among populations and ...
