    • Can root-associated fungi mediate the impact of abiotic conditions on the growth of a High Arctic herb? 

      Wutkowska, Magdalena; Ehrich, Dorothee; Mundra, Sunil; Vader, Anna; Eidesen, Pernille Bronken (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-04)
      Arctic plants are affected by many stressors. Root-associated fungi are thought to influence plant performance in stressful environmental conditions. However, the relationships are not well-known; do the number of fungal partners, their ecological functions and community composition mediate the impact of environmental conditions and/or influence host plant performance? To address these questions, ...

    • Dead or Alive; or Does It Really Matter? Level of Congruency Between Trophic Modes in Total and Active Fungal Communities in High Arctic Soil 

      Wutkowska, Magdalena; Vader, Anna; Mundra, Sunil; Cooper, Elisabeth J.; Eidesen, Pernille Bronken (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-08)
      Describing dynamics of belowground organisms, such as fungi, can be challenging. Results of studies based on environmental DNA (eDNA) may be biased as the template does not discriminate between metabolically active cells and dead biomass. We analyzed ribosomal DNA (rDNA) and ribosomal RNA (rRNA) coextracted from 48 soil samples collected from a manipulated snow depth experiment in two distinct ...

    • Linking extreme seasonality and gene expression in Arctic marine protists 

      Wutkowska, Magdalena; Vader, Anna; Logares, Ramiro; Pelletier, Eric; Gabrielsen, Tove M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-05)
      At high latitudes, strong seasonal differences in light availability affect marine organisms and regulate the timing of ecosystem processes. Marine protists are key players in Arctic aquatic ecosystems, yet little is known about their ecological roles over yearly cycles. This is especially true for the dark polar night period, which up until recently was assumed to be devoid of biological activity. ...

    • Microbial eukaryotes and their functional importance in the Arctic. A Svalbardian perspective 

      Wutkowska, Magdalena (Doctoral thesis; Doktorgradsavhandling, 2020-11-06)
      <p>Microbial eukaryotes, including protists and fungi, play diverse functions in virtually all ecosystems. In the High Arctic, their high biomass and diversity reflects crucial ecological importance and the performance of key ecological processes. Protists are the main primary producers in arctic seas, whereas fungi are an important group of decomposers and symbiotic partners of plants in terrestrial ...
