    • Extensive genome-wide phylogenetic discordance is due to incomplete lineage sorting and not ongoing introgression in a rapidly radiated bryophyte genus 

      Meleshko, Olena; Martin, Michael David; Korneliussen, Thorfinn Sand; Schröck, Christian; Lamkowski, Paul; Schmutz, Jeremy; Healey, Adam; Piatkowski, Bryan T; Shaw, A. Jonathan; Weston, David J; Flatberg, Kjell Ivar; Szövényi, Péter; Hassel, Kristian; Stenøien, Hans K. (Peer reviewed; Journal article, 2021)
      The relative importance of introgression for diversification has long been a highly disputed topic in speciation research and remains an open question despite the great attention it has received over the past decade. Gene ...

    • Long-distance dispersal and barriers shape genetic structure of peatmosses (Sphagnum) across the Northern Hemisphere 

      Kyrkjeeide, Magni Olsen; Hassel, Kristian; Flatberg, Kjell Ivar; Shaw, A. Jonathan; Brochmann, Christian; Stenøien, Hans K. (Journal article; Peer reviewed, 2016)
      Aim Disjunctly distributed peatmosses (Sphagnum) have been found to exhibit little genetic structure over regional and intercontinental scales, mainly caused by high ability for transoceanic long-distance dispersal. ...

    • Phylogenomic structure and speciation in an emerging model: the Sphagnum magellanicum complex (Bryophyta) 

      Shaw, A. Jonathan; Piatkowski, Bryan; Duffy, Aaron M.; Aguero, Blanka; Imwattana, Karn; Nieto-Lugilde, Marta; Healey, Adam; Weston, David J.; Patel, Megan N.; Schmutz, Jeremy; Grimwood, Jane; Yavitt, Joseph B.; Hassel, Kristian; Stenøien, Hans K.; Flatberg, Kjell Ivar; Bickford, Christopher P.; Hicks, Karen A. (Peer reviewed; Journal article, 2022)
      Sphagnum magellanicum is one of two Sphagnum species for which a reference-quality genome exists to facilitate research in ecological genomics. Phylogenetic and comparative genomic analyses were conducted based on ...

    • Spatial Genetic Structure of the Abundantand Widespread Peatmoss Sphagnummagellanicum Brid . 

      Kyrkjeeide, Magni Olsen; Hassel, Kristian; Flatberg, Kjell Ivar; Shaw, A. Jonathan; Yousefi, Narjes; Stenøien, Hans K. (Journal article; Peer reviewed, 2016-02-09)
      Spore-producing organisms have small dispersal units enabling them to become widespread across continents. However, barriers to gene flow and cryptic speciation may exist. The common, haploid peatmoss Sphagnum magellanicum ...

    • Sphagnum magniporosum (Sphagnaceae, subgenus Subsecunda) a new peatmoss species from Venezuela 

      Flatberg, Kjell Ivar; Hassel, Kristian; Prestø, Tommy; Kyrkjeeide, Magni Olsen; Shaw, A. Jonathan; Ahti, Teuvo (Journal article; Peer reviewed, 2022)
      We describe Sphagnum magniporosum sp. nov. in Sphagnum subgen. Subsecunda (Sphagnaceae) Bryophyta. The new species is described and characterized using morphological methods. The description is based on qualitative examination ...

    • Sphagnum Xlydiae, the first allotriploid peatmoss in the Northern hemisphere 

      Kyrkjeeide, Magni Olsen; Hassel, Kristian; Aguero, Blanka; Temsch, Eva M.; Afonina, Olga M.; Shaw, A. Jonathan; Stenøien, Hans K.; Flatberg, Kjell Ivar (Journal article; Peer reviewed, 2019)
      In plants, hybridization between interspecific taxa leading to chromosome doubling seems to happen regularly and may be an important driver of speciation. Allopolyploid species often have morphological traits from both ...
