  • Deep sympatric mitochondrial divergence without reproductive isolation in the common redstart Phoenicurus phoenicurus 
    Hogner, Silje; Laskemoen, Terje; Lifjeld, Jan Terje; Porkert, Jiri; Kleven, Oddmund; Albayrak, Tamer; Kabasakal, Bekir; Johnsen, Arild (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    Mitochondrial DNA usually shows low sequence variation within and high sequence divergence among species, which makes it a useful marker for phylogenetic inference and DNA barcoding. A previous study on the common redstart ...
  • Evolutionary analysis of the female-specific avian W chromosome 
    Smeds, Linnea; Warmuth, Vera; Bolivar, Paulina; Uebbing, Severin; Burri, Reto; Suh, Alexander; Nater, Alexander; Bures, Stanislav; Garamszegi, Laszlo Z.; Hogner, Silje; Moreno, Juan; Qvarnström, Anna; Ruzic, Milan; Sæther, Stein Are; Sætre, Glenn-Peter; Torok, Janos; Ellegren, Hans (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    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 ...
  • Genetic divergence, reproductive isolation and the early stages of speciation 
    Hogner, Silje (Doctoral thesis / Doktoravhandling, 2012)
    The process of speciation is the splitting of single populations into two or more distinct, reproductively isolated taxa. Common modes of speciation are sympatric, allopatric and parapatric speciation, with speciation in ...
  • Increased divergence but reduced variation on the Z chromosome relative to autosomes in Ficedula flycatchers: differential introgression or the faster-Z effect? 
    Hogner, Silje; Sæther, Stein Are; Borge, Thomas; Bruvik, Torbjørn; Johnsen, Arild; Sætre, Glenn-Peter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    Recent multilocus studies of congeneric birds have shown a pattern of elevated interspecific divergence on the Z chromosome compared to the autosomes. In contrast, intraspecifically, birds exhibit less polymorphism on the ...
  • Sperm performance in conspecific and heterospecific female fluid 
    Cramer, Emily Rebecca A; Stensrud, Even; Marthinsen, Gunnhild; Hogner, Silje; Johannessen, Lars Erik; Laskemoen, Terje; Eybert, Marie-Christine; Slagsvold, Tore; Lifjeld, Jan Terje; Johnsen, Arild (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Divergent sexual selection within allopatric populations may result in divergent sexual phenotypes, which can act as reproductive barriers between populations upon secondary contact. This hypothesis has been most tested ...
