A genomic delimitation of European Sphagnum subgenus Subsecunda with particular emphasis on the taxonomically difficult allodiploids Sphagnum auriculatum Schimp. and Sphagnum inundatum Russow
Petlund, Hanne Torsdatter (Master thesis, 2021)Allopolyploidi er en viktig faktor for artsdannelse i planter. Det er et utbredt fenomen blant moser og bidrar til den taksonomiske forvirringen i mange underslekter i den morfologisk og økologisk mangfoldige moseslekten ... -
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 ... -
Gene flow and genome evolution in peatmosses (Sphagnum)
Meleshko, Olena (Doctoral theses at NTNU;2021:82, Doctoral thesis, 2021)Speciation is one of the most fundamental evolutionary processes, as it creates biodiversity. Gene flow, or introgression, can bring genetic novelty into recipient species, and hence promote adaptation, while simultaneously ... -
Is interspecific gene flow and speciation in peatmosses (Sphagnum) constrained by phylogenetic relationship and life-history traits?
Meleshko, Olena; Stenøien, Hans K.; Speed, James David Mervyn; Flatberg, Kjell Ivar; Kyrkjeeide, Magni Olsen; Hassel, Kristian (Journal article; Peer reviewed, 2018)Peatmosses are interesting for studies of speciation processes not only because of their frequent hybridization and recent diversification, but also their phenotypic diversity, ecological importance and ancient history. ... -
Linked Selection and Gene Density Shape Genome-Wide Patterns of Diversification in Peatmosses
Meleshko, Olena; Martin, Michael David; Flatberg, Kjell Ivar; Stenøien, Hans Kristen; Korneliussen, Thorfinn Sand; Szövényi, Péter; Hassel, Kristian (Journal article; Peer reviewed, 2024)Genome evolution under speciation is poorly understood in nonmodel and nonvascular plants, such as bryophytes—the largest group of nonvascular land plants. Their genomes are structurally different from angiosperms and ... -
Short stories from Sphagnum of rare species, taxonomy, and speciation
Kyrkjeeide, Magni Olsen; Meleshko, Olena; Flatberg, Kjell Ivar; Hassel, Kristian (Peer reviewed; Journal article, 2023)Conserving species and their genetic variation are a global priority to safeguard evolu-tionary potential in a rapidly changing world. Species are fundamental units in research and nature management, but taxonomic work is ... -
Simulation as a tool to identify dynamical typology of water frog hemiclonal population systems
Shabanov, Dmytro; Vladymyrova, Marina; Leonov, Anton; Biriuk, Olga; Kravchenko, Marina; Mair, Quentin; Meleshko, Olena; Newman, Julian; Usova, Olena; Zholtkevych, Grygoriy (Journal article; Peer reviewed, 2019)Some related species give rise to interspecies hybrids with hemiclonal inheritance. The gametes of such hybrids transfer the set of hereditary information of one of the parental species. The water frog, Pelophylax esculentus, ... -
Spatial genetic structure in Northern European Sphagnum squarrosum Crome in relation to its Arctic morph
Nilsen, Nellie Henriette (Master thesis, 2021)Den arktiske morfen til Sphagnum squarrosum skiller seg fra den typiske Boreale morfen og har morfologiske likheter med S. teres som er nært beslektet og kan ligne på S. squarrosum når den vokser under spesifikke forhold. ... -
Whole genome data reveals possible speciation in the common peatmoss Sphagnum compactum
Brandtzæg, Nils Einar (Master thesis, 2023)Et langvarig syn innenfor mosebiogeografi er at moser har svært store utbredelsesområder og lave artsdannelse. Her studerer jeg den genetiske strukturen til den vanlige og utbredte torvmosen Sphagnum compactum Lam. & DC. ...
