    Purpose Treelines and forest lines (TFLs) have received growing interest in recent decades, due to their potential role as indicators of climate change. However, the understanding of TFL dynamics is challenged by the complex ...
  • Garcia-Navas, Vicente; Rodriguez-Rey, Marta; Marki, Petter Zahl; CHRISTIDIS, Les (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    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 ...
  • Mair, Louise; Harrison, Philip J.; Jönsson, Mari; Löbel, Swantje; Nordén, Jenni; Siitonen, Juha; Lãmås, Tomas; Lundström, Anders; Snäll, Tord (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    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)
    Despite the similar function of all sperm cells – to fertilise the egg – there is extraordinary diversity in sperm shape and length across taxa. This thesis aims to improve our understanding of how this diversity has ...
  • Anmarkrud, Jarl Andreas (Doctoral thesis / Doktoravhandling, 2011)
    Genetic variation is a prerequisite for evolution. The present thesis examines how genetic diversity arises and is maintained. The thesis can be divided into two subprojects, addressing neutral and functional genetic ...

    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 ...
  • Garcia, Javier; Johnsen, Arild; Fuertes, Benito; Suarez-Seoane, Susana (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The assessment of evolutionary divergences within subspecies complexes provide an effective short-cut for estimating intraspecific genetic diversity, which is relevant for conservation actions. We explore new evidence ...
